As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at     31   . Its cells would grow old fast and it would die young.    32    until the technique is perfectly safe, it should be     33   .
I'd love to have a clone of     34   . I often wish I had a twin sister, someone who    35   me in everything. So why not a clone? Well, the idea    36   be fun but I'm not sure if it would be     37   . I think we would be playing with fire if we let scientists go ahead with     38   cloning. There are so many     39   
involved that all research in this area should be strictly controlled.
There are so many arguments     40    cloning that it is difficult to get anyone to consider the possible benefits. I am     41    that it is a technique which could be beneficial. The most obvious use would be for childless     42   . They would be able to have babies with their own genetic material. I don't see what's wrong with that.
Imagine a child     43    up knowing that his or her mother is really a sister or a brother. The emotional     44    on the child would be     45   . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea
    46    me!
It's all very good to ban human cloning but scientists should be allowed to   47   
research. If they don't, we may     48    important benefits for our society, such as producing body organs. A clone is an     49    copy of a person with the same gene. Therefore, it is the     50    donor for an organ(器官) transplant.

When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are interested in what they leave behind: their poop(排泄物). At a recent meeting in Denver, Professor Brown at the university presented her research showing how panda poop could inspire a new way to obtain energy from plants, which are a renewable energy source. Usually, plants can be called biomass(有機(jī)燃料) when they are used as an energy source.
Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists something about breaking down biomass. Pandas—or at least the bacteria in their stomachs—are very good at getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda has only one stomach. Bamboo comes in, and poop goes out.
Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two pandas, YaYa and LeLe living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break down biomass, including one that had never been found in pandas. Brown says that because the poop contains bacteria that break down biomass, it could also be used to break down other types of biomass.
Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn biomass—like grass or other plants—into fuel.
Brown says she doesn’t mind handling panda poop. “It’s probably the most pleasant material to work with,” she says, “My colleagues and I have been working with other poop for a long time, and we can assure you it has a fairly pleasant smell associated with it.”
小題1:The importance of studying panda poop is _______.
A.to create a renewable energy from plants
B.to explore a new way to get energy from plants
C.to learn a lesson of energy from panda poop
D.to figure out how the bacteria work for us mankind
小題2:The process of the panda poop project can be described as ______.
a. Identify the chemicals helpful to break down biomass.
b. Find the bacteria in panda poop which break down bamboo.
c. Reproduce the chemicals in the lab to turn biomass into energy.
d. Analyze how the bacteria in panda poop work in panda’s stomach.
A. a, b, d, c          B. a, d, c, b          C. b, a, d, c          D. b, d, a, c
小題3:What does the author mainly want to express in the 2nd paragraph?
A.Pandas don’t digest bamboo the same way as cows.
B.Pandas are capable of getting energy using stomachs.
C.Pandas can get energy from bamboo more efficiently.
D.Scientists have learnt something new from panda poop.

Have you ever wondered why the roots of the plants always know which way to grow—into the soil but not above it? Some British scientists have recently solved this mystery.
It turns out that roots have special hairs that tie them into the soil and help them grow their way past obstacles, a team at the John Inners Center in Norwich reports in the February 29 issue of Journal Science.
“The key is in the fuzzy(有絨毛的)coat of hairs on the roots of plants,” says professor Liam Dolan. “We have found a growth control system that enables these hairs to find their way and to become longer when their path is clear.”
Root hairs explore the soil in much the same way a person would feel their way in the dark. If they come across an obstacle, they make their way around until they can continue growing in an opening. In the meantime, the plant is held in place as the hairs grip(緊緊抓住)the soil.
The hairs are guided by a clever chemical trick. A protein(蛋白質(zhì)) at the tip of the root hairs called RHD2 helps them to take calcium(鈣) from the soil. Calcium makes the hairs grow, and produce more RHD2, and take more calcium.
But when an obstacle blocks the hair’s path, or the hair reaches the surface of the soil, the cycle is broken and growth starts in another direction.
This system gives plants the flexibility to explore a complex environment and to live in even the most unpromising soils, says Dolan.
In poor soils such as in parts of Australia and Africa, native plants have adapted by producing enormous numbers of root hairs. A better understanding of this adaptation will allow scientists to develop hairy rooted crops that can grow in unfriendly environments.
According to Dolan, “Research in the John Inners Center is taking a breeding approach to increase hair length in wheat but it will be some time before new cultivars(栽培變種) are developed.”
小題1:The passage is mainly about _______.
A.why the roots of plants grow into the soil but not above it
B.how the roots of plants grow into the soil but not above it
C.the process of plants growth
D.a(chǎn) growth control system of plants
小題2:How does the circle work?
A.RHD2 takes calcium from the soil, which makes hairs grow, and produce RHD2 and take more calcium
B.Roots take RHD2 and calcium from the soil and produce RHD2
C.Roots make hairs grow, and produce RHD2, and take more calcium
D.RHD2 takes protein, which makes hairs grow, and produce RHD2, and take more calcium
小題3:We can infer from the last paragraph that ________.
A.hairy rooted crops can grow better in unfriendly environments
B.a(chǎn) new cultivar of wheat with long hair has been developed by scientists
C.a(chǎn) new cultivar of wheat with long hair is still on test
D.the roots of plants always know which way to grow

A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors.
On one side stand those who see clothes dryers (干衣機(jī)) as a waste of energy and a major polluter of the environment.As a result, they are turning to clotheslines as part of the “what-I-can-do environmentalism.”
On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at.They have persuaded Homeowners Associations (HOAs) access the U.S.to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood.
This has led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines.So far, only three states have laws to protect clothesline.Right-to-Dry supporters argue that there should be more.
Matt Reck, 37, is the kind of eco-conscious(有生態(tài)意識的)person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants.His family also uses a clothesline.But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighbor had telephoned them about his clothesline.The Recks paid no attention to the warning and still dried their clothes on a line in the yard.“Many people say they are environmentally friendly but they don’t take matters into their own hands,” says Reck.The local HOA has decided not to take any action, unless more neighbors come to them.
North Carolina lawmakers are saying that banning clotheslines is not the right thing to do.But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods.They worry that if buyers think their future neighbors can’t even afford dryers, housing prices will fall.
Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change.As they say, “The clothesline is beautiful.Hanging clothes outside should be encouraged.We all have to do at least something to slow down the process of global warming.”
小題1:One of the reasons why supporters of clothes dryers are trying to ban clothesline drying is that ______.
A.clothes dryers are more efficient
B.clothesline drying reduces home value
C.clothes dryers are energy-saving
D.clothesline drying is not allowed in most U.S.states
小題2:Who are in favor of clothesline drying?
A.Housing businesses.
B.Environmentalists.
C.Homeowners Associations.
D.Reck’s dissatisfied neighbors.
小題3:What is mainly discussed in the text?
A.Clothesline drying: a way to save energy and money.
B.Clothesline drying: a lost art rediscovered.
C.Opposite opinions on clothesline drying.
D.Different varieties of clotheslines.

A farm planted levels or floors is called a vertical(垂直的)farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards,rather than outwards,it requires much less space than a conventional farm.
The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18­story vertical farm could feed as many as 50,000 people,all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time,food would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides(殺蟲劑) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space,therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course,not all food does well with this type of planting,but there are many crops that actually seem to do better.
In some climates,a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words,we could grow crops in areas where we never could before.
Vertical farms may just be a concept for now,but they are a concept that will solve many of our problems in the future.
小題1:According to the passage, a vertical farm________.
A.is mainly built outwards
B.is dependent on solar power
C.is planted on levels upwards
D.is only an environmental friendly farm
小題2:Compared to the conventional farm, the vertical farm can________.
A.depend far less on sunlight
B.greatly increase the use of soil
C.help to protect the limited gardens
D.reduce the use of harmful pesticides
小題3:It can be learned from the passage that vertical farms________.
A.have been put into use
B.only use hydroponics to grow food
C.need less room than conventional farms
D.may increase the transportation costs
小題4:What would be the best title for the passage?
A.Vertical farms for our future
B.Ways to deal with future problems
C.Vertical farms and green skyscrapers
D.Making Full Use of Our Limited Land

The flying fox is not a fox at all. It is an extra large bat that has got a fox’s head, and that feeds on fruit. Like all bats, flying foxes hang themselves by their toes (趾) when at rest, and travel in great crowds when out flying. A group will live in one place for years. Sometimes several hundreds of them occupy a single tree. As they return to the tree towards sunrise, they quarrel among themselves and fight for the best places until long after daylight.
Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her chest wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls to the ground. Then the older ones fly down and try to pick it up. If they fail to do so, it will die. Often hundreds of baby bats can be found lying on the ground at the foot of the tree.
小題1:The passage tells us that there is no difference between the flying fox and the ordinary bat in ______.
A.their size B.their appearance
C.the kind of food they eat D.the way they rest
小題2:Flying foxes ______.

Sea turtles come in many different sizes, shapes and colors. The shell of each sea turtle species is different in length, color, shape and the arrangement of the scales(鱗片).
Sea turtles do not have teeth but use their jaws (下巴)to eat. Their sense of smell is excellent. Their eyesight underwater is good, but they have near-sighted eyes out of water. Their special bodies make them adapt to life at sea. However, sea turtles maintain(保持) close ties to land.
Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore, all baby sea turtles begin their lives on land. Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest, largely because they can be found most easily. After decades of studying sea turtles, much has been learned about. However, many mysteries(謎) still remain.
Researchers do not yet know how long baby turtles spend in the open sea, or exactly where they go. People believe they spend their earliest years floating in the sea, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in waters near the shore. They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles, depending on the species. There is no way to know the age of a sea turtle from its physical appearance. It is believed that some species can live for over 100 years.
小題1:Which of the following statements is NOT true about sea turtles?
A.They don’t use teeth to eat.
B.They have a good sense of smell.
C.Sea turtles are more adaptable to life at sea.
D.Different species have different shells.
小題2:The underlined phrase “near-sighted eyes” in the second paragraph means_____.
A.good eyesightB.bad eyes

Surprisingly, no one knows how many children receive education in English hospitals, still less the content or quality of that education. Proper records are just not kept. We know that more than 850,000 children go through hospital each year, and that every child of school age has a legal right to continue to receive education while in hospital. We also know there is only one hospital teacher to every 1,000 children in hospital.
Little wonder the latest survey concludes that the extent and type of hospital teaching available differ a great deal across the country. It is found that half the hospitals in England which admit children have no teacher. A further quarter have only a part-time teacher. The special children’s hospitals in major cities do best; general hospitals in the country and holiday areas are worst off. From this survey, one can estimate that fewer than one in five children have some contact with a hospital teacher—and that contact may be as little as two hours a day. Most children interviewed were surprised to find a teacher in hospital at all. They had not been prepared for it by parents or their own school. If there was a teacher they were much more likely to read books and do math or number work; without a teacher they would only play games.
Reasons for hospital teaching range from preventing a child falling behind and maintaining the habit of school to keeping a child occupied, and the latter is often all the teacher can do. The position and influence of many teachers was summed up when parents referred to them as “the library lady” or just “the helper”. Children tend to rely on concerned school friends to keep in touch with school work. Several parents spoke of requests for work being ignored or refused by the school. Once back at school children rarely get extra teaching, and are told to catch up as best they can.
Many short-stay child-patients catch up quickly. But schools do very little to ease the anxiety about falling behind expressed by many of the children interviewed.
小題1:Which of the following statements is true?
A.Every child in hospital receives some teaching.
B.Not enough is known about hospital teaching.
C.Hospital teaching is of poor quality.
D.The special children's hospitals are worst off.
小題2:It can be inferred from the latest survey that________.
A.hospital teaching across the country is similar
B.each hospital has at least one part-time teacher
C.a(chǎn)ll hospitals surveyed offer education to children
D.only one-fourth of the hospital have full-time teacher
小題3:The hospital teachers are found________.
A.not welcomed by the children and their parentsB.unnecessary
C.not quite helpfulD.capable
小題4:In order to catch up with their school work, children in hospital usually turn to________.
A.hospital teachersB.schoolmatesC.parents D.school teachers
小題5:We can conclude from the passage that the author is________.
A.unfavorable towards children receiving education in hospitals
B.in favor of the present state of teaching in hospitals
C.unsatisfied with the present state of hospital teaching
D.satisfied with the results of the latest survey
