Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate, you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo(竹子) . Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied(多樣化) diet . The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

It was your birthday, and you just opened your biggest gift — a smooth silver laptop. You can’t wait to instant-message your friends with the news, but first you have to get rid of your old desktop computer. Do you just throw away the monitor and keyboard in the trash? Not anymore!
Three states, that is, California, Maine, and Maryland, recently passed laws prohibiting people from throwing away electronic waste, or e-waste, includes televisions, computers, and cell phones. Although they don’t make you sick when you use them, they do when they are destroyed, for they contain heavy metals that can be harmful to human bodies. For example, cell phone batteries contain a kind of chemical causing damage to kidneys and deserted computer monitors can damage brains. And flat TV screens may cause injury to the nervous system. Those metals can leak into the ground or give off pollutants when burned.
It is required that e-waste be placed at special sites rather than usual landfills. Several other states are considering similar laws and California is also pushing for a law banning the application of such dangerous substances.
Government officials are not the only people taking aim at e-waste; environmentalists are also urging people to recycle their outdated equipment.
“It is just a waste … to not recycle,” Patrick, an associate professor of occupational and environmental health at university of Iowa, told The Daily Iowan, “Allowing dangerous chemicals to leak into the environment for decades seems irresponsible.”
What Can You Do?
Reduce. Be a responsible shopper, and take care of your electronics so they will last longer.
Re-use. Donate or sell your old high-tech equipment.
Recycle. To find a responsible recycler, contact a local or state environmental group.
小題1:What’s the best title of this passage?
A．E-waste is being made good use of.
B．E-waste, a big threat to us.
C．E-waste is dangerous to us all the while.
D．Goodbye, e-waste.
小題2:Why is e-waste harmful and dangerous to human beings?
A．Because they can go off at times and threaten us.
B．Because they can make people sick, as long as people use them.
C．Because they contain poisonous chemical substances.
D．Because they take too much space when placed in trashes.
小題3:What can we know from Patrick’s words?
A．Waste can’t be recycled.
B．Waste can be made use of by recycling
C．We have to recycle e-waste to protect the environment.
D．Protecting the environment is important.
小題4:Which of the following is NOT given as a piece of advice to help with e-wastes?
A．Taking care of your electronics so they will last longer.
B．Donating or selling your old high-tech equipment.
C．Contacting a local or state environmental group.
D．Asking fewer people to use electric products.

The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾倫望遠(yuǎn)鏡陣列) in Hat Creek, California. The telescopes were partly made possible by a gift of twenty-five million dollars from Paul Allen. The total cost of the project is already fifty million dollars.
At present, there are 42 radio telescopes working at the Hat Creek observatory. The signals they receive are combined to create what is equal to a single, very large telescope. The telescope will be used to observe objects like exploding stars, black holes and other objects that are predicted but have not yet been observed. Seth Shostak of the SETI Institute says this is the first telescope whose main purpose is to search for signals from intelligent life in space. The SETI Institute is based in Mountain View, California. The organization supports the search for other life forms in the universe.
What makes the Allen Telescope Array unusual is that it can collect and study information from a wide area of the sky. In addition, the 42 telescopes can study information about several projects at the same time. That means studies of large areas of the sky can be made faster than ever before.
Some officials think the Allen Telescope Array will be completed in three more years. 350 individual radio telescopes are planned. The new abilities of the Allen Telescope Array will make searching for stars similar to the sun much faster.
An earlier search by SETI, Project Phoenix, studied about 800 stars to a distance of 240 light years. The project ended in 2004. With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.
小題1:The main purpose of the Allen Telescope Array is          .
A．to serve for the research of weather predication
B．to prepare for the wars against life from the universe
C．to search for signals from intelligent life in space
D．to observe exploding stars, black holes and other objects
小題2:From this passage we know that         .
A．the 42 radio telescopes at Hat Creek observatory can work together
B．the total cost of the project came from Paul Allen
C．Hat Creek observatory can receive signals from all parts of the worm
D．Hat Creek observatory is operated by an American named Paul Allen
小題3:Which of the following is TRUE according to this passage?
A．The Allen Telescope Array takes much more room than former telescopes.
B．The Allen Telescope Array is still being built at present in the United States.
C．Another 42 radio telescopes will be fixed in the Allen Telescope Array.
D．The SETI Institute is against the search for other life forms in the universes.
小題4:With the help of the Allen Telescope Array,         .
A．a(chǎn)stronomers can gather more information than before from other planets
B．humans will have more chances to live on other planets than before
C．humans will be able to find more natural resources on other planets
D．scientists will be able to find more natural resources from other planets

C
So long as teachers fail to distinguish between teaching and learning, they will continue to undertake everything to do for children that only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.
Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also a public activity. It can be seen and observed.
Learning to read, however, involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest (探索) for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of learning to read by reading.
小題1:The problem with the reading course as mentioned in the first paragraph is that
________.
A．it is one of the most difficult school courses
B．students spend endless hours in reading
C．reading tasks are assigned with little guidance
D．too much time is spent in teaching about reading
小題2:The teaching of reading will be successful if ________.
A．teachers can improve conditions at school for the students
B．teachers can enable students to develop their own way of reading
C．teachers can devise the most efficient system for reading
D．teachers can make their teaching activities observable
小題3:The underlined word “scrutiny” most probably means “________”.
A．inquiryB．observationC．controlD．suspect
小題4:According to the passage, learning to read will no longer be a difficult task when
________.
A．children become highly motivated
B．teacher and learner roles are interchangeable
C．teaching helps children in the search for knowledge
D．reading enriches children’s experience
小題5: The main idea of the passage is that ________.
A．teachers should do nothing in helping students learn to read
B．teachers should encourage students to read as widely as possible
C．reading ability is something acquired rather than taught
D．reading is more complicated than generally believed

An astronomer is making a case for launching pop singer Justin Bieber into suborbital（亞軌道的）space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager — he would come back down to Earth eventually, after all — but rather to help jump-start the emerging suborbital spaceflight industry.
It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. “If there’s more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good.”
Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport.
None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z.
Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists — but Shostak is thinking about ways to make it grow.
A celebrity launch isn't Shostak’s only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling（充滿）with cameras both inside and out, to give the public dramatic views of every mission.
Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry’s success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
小題1:Why may Justin Bieber be sent into suborbital space?
A．To show his bravery and make him a role model for teenagers.
B．To arouse the American public’s interest.
C．To help reform the spaceflight industry.
D．To film an advertisement about space.
小題2:What can we learn about suborbital spaceflight?
A．A trip will return to Earth before finishing a lap.
B．The whole trip will leave passengers weightless.
C．Each trip can take 500 passengers.
D．The trip will be too expensive even for celebrities.
小題3:What can we infer from the text?
A．SpaceShipTwo will be the first to fly.
B．Famous people will be the main passengers in the future.
C．The space trip is still in preparation.
D．Every space trip will be made into a film.
小題4:The last paragraph suggests that _________.
A．space is too mysterious to explore
B．the suborbital market is promising
C．the spaceflight industry is more successful than people think
D．developing the industry is risky
小題5:What is the main purpose of the text?
A．To predict a change in the space market.
B．To discuss a recent launch.
C．To introduce the status of the spaceflight industry.
D．To remove public doubt about the spaceflight industry.

Almost everyone suffers from a headache sometimes.But some people suffer from repeated, frequent headaches.
What is headache? What causes it? What can be done about a headache? What research is being done on headaches?
The dictionary defines(下定義) headache simply as “a pain in the head.” What most people mean by headache is a pain which lasts several minutes or hours.It covers the whole head, or one side of it, or perhaps the front or the back of the head.To add to the confusion(困惑) about a definition, some people call tight feeling in the head a headache.
A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early.If a person removes the warning, day after day, with a pain-killer, he may pass the point of easy control.
The professional name for covering up a symptom(癥狀) is “masking” (遮蔽).A headache specialist once said, “Masking symptoms is not the best way of treatment.” He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia(貧血癥) while bleeding continues undiscovered.He added, “Sometimes it is wiser to stand still than to advance in darkness.”
A headache is important also because it affects normal, happy living.The employee with a headache does less work.In a flash of temper he may upset his fellow workers or customers, causing a direct or indirect loss to his organization.The mother with a headache suffers and disturbs the family.She upsets her husband and children.
小題1:Which is true according to the passage?

These days, young children can enjoy directly what it is like to be a marine biologist (海洋生物學(xué)家) at a marine association. What they discover can lead them to appreciate and protect the ocean and also the animals living in it.
At the present time, learning isn’t only limited to the classroom. It’s quite common for kids to learn from outdoor experiences. Teachers commonly take their pupils on field trips to museums as well as other interesting areas. If you wish to help pupils to take care of the ocean, one of the best areas to take them to is a marine association, the place where the ocean biome (生物圈) is shown.
Taking your pupils to a marine association is a prefect way to help them learn. Education professionals agree that there are topics that children can learn more successfully whenever they experience them directly.
Several organizations that focused on protecting the ocean now operate on the coast of different areas in America and all around the world. It’s quite common for marine associations nowadays to open their doors several times a week to kids, parents, and ocean lovers to learn more about the ocean biome.
A marine association has different programs for children of different ages. You’ll find programs that are developed specially for pupils. Pupils are involved in interactive (互動(dòng)的) learning. This learning experience allows young children to recognize the value of the role each species performs in their environment. They not only get to research creatures from the ocean, but they also get to see, touch, and smell most of these animals and plants. This type of exposure offers students an idea about the life of a marine scientist. It could help them choose a career afterwards.
These programs are generally held on Saturdays and Sundays in order that kids and parents can have more hours in which to have fun. Teachers who want to arrange these activities for their students can call a local marine association near them.
小題1:According to the text, pupils can have a better understanding of the ocean biome by _______.
A．learning about it from books
B．going to a marine association
C．a(chǎn)ttending marine biologists’ meetings
D．taking part-time jobs at marine associations
小題2:In Paragraph 5, the author mainly wants to tell us _______.
A．the advantage of learning at a marine association
B．different activities offered by a marine association
C．a(chǎn) marine association’s working conditions
D．the way to develop children’s interest in ocean
小題3:The underlined word “exposure” in Paragraph 5 probably means _______.
A．the way of explaining something
B．the way of choosing a career
C．a(chǎn) marine association’s working condition
D．the way to develop children’s interest in the ocean
小題4:Which of the following is TURE?
A．Young children can enjoy indirectly what it is like to be a marine biologist at a marine association.
B．To help your pupils to take care of the ocean, the best area to take them to is a marine association.
C．Children can learn the topics more successfully when they experience them directly.
D．A marine association has the same program for children of different ages.
小題5:The text is most probably taken from _______.
A．a(chǎn) teacher’s presentation
B．a(chǎn) marine biologist’s report
C．a(chǎn) student’s field trip journal
D．a(chǎn)n introduction to a marine association

When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction. 
Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
小題1:The aim of the extinction of large prehistoric animals is to suggest that _______.
A．large animal were not easy to survive in the changing environment
B．small species survived as large animals disappeared
C．large sea animals may face the same threat today.
D．Slow-growing fish outlive fast-growing ones
小題2:We can infer from Dr Myers and Dr. Worm’s paper that _______.
A．the stock of large predators in some old fisheries has reduced by 90%
B．there are only half as many fisheries are there were 15 years ago
C．the catch sizes in new fisheries are only 20% of the original amount
D．the number of larger predators dropped faster in new fisheries than in the old
小題3:By saying these figures are conservative (line 1, paragraph 3), Dr worm means that_______.
A．fishing technology has improved rapidly
B．then catch-sizes are actually smaller then recorded
C．the marine biomass has suffered a greater loss
D．the date collected so far are out of date.
小題4:Dr Myers and other researchers hold that _______.
A．people should look for a baseline that can’t work for a longer time
B．fisheries should keep the yield below 50% of the biomass
C．the ocean biomass should restore its original level.
D．people should adjust the fishing baseline to changing situation.
小題5:The author seems to be mainly concerned with most fisheries’ _______.
A．management efficiency
B．biomass level
C．catch-size limits
D．technological application.
