Do your children always sit still and watch TV? If so, you should be very alert!
Nowadays, children watch television for long hours. They often spend evenings watching their favorite programs on TV. Sometimes they might stay up late to watch TV. Their addiction to television results in their not having time to play or do exercise. They should go outside with friends or spend time reading books. Moreover, watching television too much is harmful to their eyesight.
Researchers claim that attention deficit disorders in children are a result of watching too much television. They say that watching television leads to a developmental disorder in the part of the brain which is responsible for language skills. Children who watch television more and read less have greater difficulty paying attention and concentrating. Children that spend long hours watching television are more likely to be affected by attention deficit disorders.
Television is one form of media which is used to show all kinds of products. Watching too much television can lead to early exposure to a wide variety of things. Television advertisements may cause children to behave incorrectly or damage themselves. Advertisements about fast food, cold drinks or other such products that are not good for children’s health can have a bad effect on them. Some TV shows and films also affect how children think and behave.
Studies in psychology have shown that certain programs can have a long-lasting effect on children’s minds. Horror scenes and other frightening shows can have a negative effect on the minds of children watching them.
Television is a means of recreation but watching it too often is harmful to children’s physical and mental health. You need to help you children deep a balance of everything in life.

The quest for success always begins with a target. As Berra once said , ＂you get to be very careful if you don＇t know where you＇re going, because you might not get there.＂
Too many people wander through life like sleepwalkers. Each day they follow familiar routines, never asking, ＂What am I doing with my life?＂and they don＇t know what they＇re doing because they lack goals.
Goal-setting is a focus of the will to move in a certain direction. Begin with a clear conception of what you want. Write down your goals and date them---putting them into words clarifies them. Rather than concentrating on objects to acquire and possess, focus on fulfilling your desires to do, to produce, to contribute to goal-setting that yields the true sense of satisfaction we all need.
It’s important to visualize(想象)yourself accomplishing your goal. While losers visualize the penalties(不利) of failure, winners visualize the rewards of success. I’ve seen it among athletes, statistics contrasting air and highway safety, but it made no difference. I had read too many articles describing crash scenes and imagined these scenes vividly. I had programmed myself, without realizing it ,to stay off planes.
Then one summer I had the opportunity to fly on a private plane with friends to a resort; I didn’t want to miss out on a great vacation. So I spent two weeks imagining a smooth flight on a beautiful sunny day and an easy landing.
When the day arrived, I was eager to go . To everyone＇s surprise, I got on the plane and I loved every minute of it , and I still use the techniques I employed that day.

I was telling my boy Sonny the story of the hare (兔子) and the tortoise (烏龜). At the end I said, “ Son, remember: Be slow and steady (鎮(zhèn)定的), and that will win the race. Don’t you think there’s something to learn from the tortoise?”
Sonny opened his eyes wide, “Do you mean next time when I’m entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?”
I was shocked, “But the tortoise didn’t wish that the hare would fall asleep!”
“He must have wished that,” Sonny said, “Otherwise how could he be so foolish as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did.”
“He didn’t have such a wish,” I insisted. “He won the race by perseverance (堅(jiān)忍不拔的), by pushing on steadily.”
Sonny thought a while. “That’s a lie,” he said. “He won it because he was lucky. If the hare hadn’t happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he’d never have won the race. That’s for sure.”
I gave up. Today’s children are not like what we used to be. They’re just hopeless.

Batteries can power anything from small sensors to large systems．While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves．University of Missouri（MU） researchers are developing a nuclear energy source that is smaller, lighter and more efficient．
“To provide enough power, we need certain methods with high energy density（密度）”，said Jae Kwon, assistant professor of electrical and computer engineering at MU．“The radioisotope（放射性同位素） battery can provide power density that is much higher than chemical batteries．”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems （M/NEMS）．Although nuclear batteries can cause concerns, Kwon said they are safe．
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems．”
His new idea is not only in the battery’s size, but also in its semiconductor（半導(dǎo)體）．Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor．
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure（晶體結(jié)構(gòu)） of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem．”
Together with J．David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery．In the future, they hope to increase the battery’s power, shrink its size and try with various other materials．Kwon said that battery could be thinner than the thickness of human hair．
小題1:Jae Kwon gave examples in Paragraph 4_________．

A．to show chemical batteries are widely applied．

B．to introduce nuclear batteries can be safely used．

C．to describe a nuclear-powered system．

D．to introduce various energy sources．

小題2:According to Jae Kwon, his nuclear battery _______．

A．uses a solid semiconductor	B．will soon replace the present ones．
C．could be extremely thin	D．has passed the final test．

小題3:The text is most probably a ________．

A．science news report	B．book review
C．newspaper ad	D．science fiction

Surgeons in Spain have successfully carried out the world’s first organ transplant using new stem cell technology. Some people are calling it the greatest medical breakthrough so far this century.
But what are stem cells? As we know, most cells in our bodies are designed to serve specific purposes – for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young, and in the laboratory scientists can grow them into different types of cell.
Claudia Castillo needed a new windpipe after getting a serious disease. Scientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had recently died. They used strong chemicals to remove the donor’s cells, leaving a tissue scaffold(組織支架). This was refilled with cells from Ms Castillo’s windpipe, and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo.
Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejection. But by using Ms Castillo’s own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health.
This ground-breaking procedure could be used in other transplant operations in the future. Scientists also believe stem cells might be used to treat Parkinson's disease, Alzheimer's disease, heart disease, stroke, arthritis, diabetes, burns and so on.
However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos created in laboratories and which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases.
小題1:This transplant is considered the greatest medical breakthrough because _________.

A．this is the first organ transplant in the whole world

B．the patient is in perfect health after the operation

C．it is the first success with new stem cell technology

D．the stem cells are from an embryo developed in a lab

小題2:Stem cells are different from the other ceils in the way that __________.

A．they are grown in the lab only

B．they can grow into different types of cell

C．they are designed for a specific purpose

D．they can work in the liver not in the heart

小題3:What is the main idea of the third paragraph?

A．How Claudia survived in the operation

B．How to remove the cells from the donor’s organ

C．Why stem cells are needed in the transplant

D．How the windpipe is transplanted

小題4:Which of the following is TRUE according to the passage?

A．Human bodies always reject transplanted organs even with their own cells

B．The donor’s cells had to be removed because they were unhealthy

C．The transplanted organ was refilled with the stem cells only

D．Claudia will not have to take drugs to prevent rejection.

小題5:Which word can best describe the scientists’ attitude towards the stem cell technology?

A．controversial	B．confident
C．conservative (保守的)	D．critical

It is easier to float in the ocean than it is to float in a swimming pool. Do you know why?
Ocean water is full of salt— and salt water can hold up more weigh than fresh water. See for yourself!
You Will Need:
● 3 cups of warm water
● Measuring cup (量杯)
● Wide-mouthed jar
● Salt
● Spoon
● Raw (生的)potato
You Will Do:
1. Pour 1.5 cups of warm water into the jar.
2. Add 1/3 cup of salt.
3. Stir(攪拌) until the salt is completely dissolved.
4. Add another 1.5 cups of water. Pour it slowly over the back of the spoon into the jar so that the two liquid will not mix together.
5. Gently place the potato into the jar. Do not drop it.
What Will Happen:
The potato will sink— but only halfway!
Why?
Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top.
The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down.
小題1:In the experiment, what should you do right after you pour the water over the spoon?

A．Add the salt to the water.	B．Stir the salt into the water.
C．Place the potato in the jar.	D．Pour warm water into thejar.

小題2:In Step 4 of the experiment, why do you pour the water over the spoon “slowly”?

A．It is easier to see what you are doing.

B．It pushes the fresh water to the bottom.

C．It will keep the water from coming out.

D．It will keep the liquids from mixing together.

小題3:In which step of the experiment do you add the salt?

A．Step 1

B．Step 2

C．Step 3

D．Step 4

小題4:What does the underlined word “gently” mean?

A．Carefully

B．Quickly

C．Secretly

D．Silently

Researchers at San Diego Zoo have been studying what has been described as the “secret language” of elephants. They have been monitoring（監(jiān)測(cè)） communications between animals that cannot be heard by human ears.
The elephant’s call will be familiar to most people, but the animals also give out growls (低吼). Their growls, however, are only partly audible (聽(tīng)得見(jiàn)的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”
The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation (妊娠期) of over two years, in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,” said Dr Anderson.
The researchers believe that this also warns the elephants to look out for coming danger. “You may think that a baby calf of about 300 pounds would not be as open to predation (捕食) as other species,” he says. “But packs of hyenas (袋狼) are a big threat in the wild.”
Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.
小題1:Why some elephants’ call is called “secret language”?

A．Because it can’t be heard by human ears.

B．Because it can only be heard by female elephants.

C．Because people don’t know its meanings.

D．Because people haven’t studied it completely.

小題2:By using a sensitive microphone and a GPS tracking system, the researchers wanted to find out             .

A．where the elephants usually go

B．what the elephants’ growls really mean

C．how mother elephants raise baby calves

D．how elephants protect their babies.

小題3:A pregnant elephant uses inaudible growls to           .

A．show the location where she is staying

B．a(chǎn)sk for help when she losses her way

C．scare away the enemy

D．let others know she will have a baby

小題4:What is the passage mainly about?

A．The elephants can speak like people.

B．The wild elephants’ ways to fight against enemies.

C．The “secret language” between elephants.

D．The special life of female elephants.

___1____ Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.
However, they sing most of the time for a very different reason. ____2___ Some scientists believe that birds do sing some of the time just because they are happy.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims(聲稱)as its own. ____3___ No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away. If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting(筑巢)season. So he is screaming all the time, whether he can see an outsider or not.__4__.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language all their own. ___5__

A．Only he and his family are welcome there.

B．Most of it has to do with attracting mates and setting up territories.

C．Have you ever wondered why birds sing?

D．Their singing is actually a warning to other birds to stay out of their territory.

E. Have you ever wondered why birds sing?
F. Most of the language is widely used.
G. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

Travis laughed as he tore at the wrapping paper on his birthday present．He was so    16 ! Finally, he would have the coolest pair of name-brand basketball shoes．
All the guys on his team were wearing the name-brand shoes of a popular basketball   17  , Chuck Hart．    18   Hart was criticized for his poor sportsmanship（運(yùn)動(dòng)員風(fēng)范） and infamous（臭名遠(yuǎn)揚(yáng)的）   19 , he was a great player．In fact, Travis wasn't thinking about Hart' s behavior; he had only expected to see Hart' s  20  on the side of the box．The first indication that something was   21  came as he tore away the last piece of paper．Not Hart' s．The new shoes were the name-brand of another player, Robert Ryann, who was   22   for his amazing work in the community．
