The air plant has wonderful and amazing features. It takes in moisture(水汽)from the air through its leaves．Although it is seen growing on another object or plant to support itself.
To prevent the roots from being too wet，avoid(避免) planting it in soil. Keep the roots in a well—ventilated(通风良好的)environment. Air plants can grow well hanging from fishing lines. They can also be hung from seashells, teacups or even on wood.
Water the air plant once in a while. Simply let the water fall from the roots. The roots will take in the water for the air plant. The air plant can live between 0℃° and 51 ℃. It does not need to be in the light all the time. However, sunlight(morning and evening only)helps it to reproduce(繁殖)faster. When it flowers，it turns a colorful pink, red or orange．At most 8 young plants can grow from the air plant．When these grow to half the size of the parent plant, simply pull them away gently from the parent plant and plant them in another place．
The lifespan of an air plant depends on the care it gets and the environment it is placed in. Generally, all air plant can live for many years.
Because they are so beautiful and easy to take care of, air plants are excellent as birthday gifts or housewarming gifts.

(C)The earth is not only, but also thirsty for water. This may seem strange to you. because nearly 70% of the earth’s surface（表面）is covered with water. But about 97% of that is sea water, or salt water. Man can only use the other 3%—the fresh water from rivers, lakes, and other sources. And we can’t even use all of that, because some of it is in the form of icebergs and glaciers（冰川）. Even worse, some of it has been polluted.
However, as things stand today, the fresh water is still enough for us. But our need for water is becoming larger and larger quickly—almost day by day. We should take steps to do with this problem now and in this way we can get away from a serious world-wide water shortage later on.
We all have to learn how to stop wasting our valuable water, one of the first step is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system(下水道), from there it returns to sea or runs into underground (地下)places.
But even if every large city reused its water, we still would not have enough. All we’d have to do to make use of sea water in the world is to remove the salt.
小题1: The earth is thirsty for water because_______ .

A．man has not enough food to eat.

小题3: What can we do if we want to have enough fresh water?
(a) make good use of the sea water.
(b) carry salt water into lakes and rivers.
(c) try to save the fresh water as much as possible
(d) do our best to use the water again.
(e) drink and use all the water on the earth’s surface

A．(c)and(e)	B．(a) and (b)
C．(a), (c)and(d)	D．(b) , (d) and(e)

小题4: The best but the most difficult way to solve the water problem of the world is to ___

A．remove the salt from the sea water

B．make the water in the cities clean.

C．take the water from underground

D．make the need for the water smaller.

小题5: What is the best title for this passage?

ARE you creative, shy, outgoing? Our personalities reveal a lot about who we are. But what’s surprising is that our personality can also say something about our health. That’s according to researchers at Duke University, US.
During an experiment on 1,000 people, scientists assessed (评定) their personalities in two ways: by asking someone they knew, such as a family member or friend; then by asking someone they had just met, such as a nurse. The study found that those who were careful at age 26 were in better health after 12 years.?
Being careful means that people tend to have a lot of self-control, and are less likely to smoke, the scientists said. Careful people are also more likely to have an active lifestyle and healthy diet.
From those who were least careful, 45 percent developed health problems by the age of 38. Such health issues included gum disease and high blood pressure (高血压). To compare, only 18 percent of careful people went on to develop health problems.
Another positive personality was called “openness to experience”, meaning curious and imaginative. People who have more of this personality have higher IQ scores. So they’d be more likely to know how to find medical help to prevent disease.
According to the report, if doctors assessed our personalities, it could help doctors to find which young adults need advice on how to live a healthy lifestyle. What’s surprising is that stress didn’t play a big part on a person’s health. Even though stress and anxiety (焦虑) are usually linked to bad health.
But can a doctor who knows our personality really improve our health? Or should doctors be kept away from knowing something so personal?
小题1:Which personality type may be better for our health, according to the research?

A．self-controlled.	B．Stressed.
C．Shy.	D．Careless.

小题2:From the passage, we learn that careful people ____.

A．are too shy to talk to strangers

B．love to ask the doctor for advice

C．are likely to have a healthy lifestyle

D．may have high blood pressure when they’re older

小题3:Where can you probably read the article?

A．Newspaper.	B．Science fiction book.
C．Research paper.	D．Travel guide.

小题4:What is the main idea of the article?

A．People can change their personality type.

B．Scientists have found two different personality types.

C．Personalities have something to do with our lifestyle.

D．Personalities say something about our health.

After shaking the east coast of Honshu, Japan on March 11, the earthquake has caused more than 10, 000 deaths and 17, 000 people missing. In downtown of Tokyo, buildings shook and frightened citizen blocked out all the streets and roads. The tsunami（飓风）afterwards, which caused more deaths and injury, made Japanese people unable to cheer up. “Now that our neighbors are in trouble,” the Foreign Ministry spokesman said, “we are in our turn to give a hand. Our rescue team has already got there in time to help.” The terrible earthquake also caused a big fire breaking out at the Fukushima nuclear power plant（福岛核电站）, leading to a radiation leaking（泄漏）.
50 nuclear workers, facing radiation and fire, became the only people remaining at the Fukushima nuclear power plant on Tuesday — and perhaps Japan’s last chance of preventing a broader nuclear danger. They have volunteered to put seawater on dangerous nuclear fuel（核燃料）to cool it down, to prevent thousands of tons of radioactive dust high into the air. Some scientists suggest that the leaking is harmful to human being and may influence human body through rain or snow from the sky in the future.

Fishing is a popular activity and every fisherman knows the rule: Keep the big ones, throw the smaller ones back. The idea behind Lt is simple - the larger fish are probably older. If you keep the smaller ones, they won’t be able to reproduce, and the fish population is in danger.
But fishing out the largest fish from a population has an unwanted effect: Over time, fewer adult fish get really big. If only the smaller fish reproduce（繁殖）, then future generations become smaller. This is an example of evolution（进化） in action.
One scientist, Dr David Conover has spent the last decade studying the effects of the “keep the big ones” rule and if they can be reversed（颠倒）.
To set up his experiment, Conover and his team caught hundreds of silverside fish and divided them into six groups. For two groups, Conover followed the “keep the large ones” rule and took out the biggest fish. For two other groups, he removed only the small fish.
For the last two groups, he removed fish at random (随意的).
After five years, he measured the fish in each group. In the two groups where the largest fish were regularly removed, the average fish size was smaller than the average size in the other groups. Here was evolution in action: If only small fish survive to reproduce, then future generations of fish will also tend to be small.
For the second five years of his experiment, Conover changed the rules and took fish randomly from each group. At the end of the experiment, he found that the fish that were in the “keep the large ones” group for the first five years had started to get larger again, although he calculated it would take at least 12 years for the fish in that group to return to their original size.
In other words, it takes less time to shrink(变小) than it does to recover.
小题1: The underlined word “it” (Line 2) refers to “ ”

A．the activity	B．the fish
C．the rule	D．the fisherman

小题2:Why do many people follow the “keep the big ones, throw the small ones back” rule?

A．It helps to protect fish numbers.

B．It helps to protect fish size.

C．It is the custom in most countries.

D．They will be punished if they don’t.

小题3:What did Conover find after the first five years of his experiment?

A．The “keep the big ones” rule made no difference to fish size.

B．The “keep the big ones” rule made fish smaller on average.

C．The “keep the big ones” rule made the fish bigger on average.

D．The “keep the big ones” rule affected all fish populations in the same way.

小题4: What is the author’s intention in writing this article?

A．To encourage people to fish more carefully.

B．To urge governments to change the rules of fishing.

C．To describe the results of a scientific experiment.

D．To introduce the rules of fishing to readers.

B
People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many meanings using the word “mouth”. But some of them are not so nice.
For example, if you say bad things about a person, the person might protest (抗议) and say “Do not bad mouth me.”
Sometimes, people say something to a friend or family member that they later regret(后悔) because it hurts that person’s feelings. Or they tell the person something they were not supposed to tell. The speaker might say, “I really put my foot in my mouth this time.” In other words, he might feel sad for saying the wrong thing.
Sometimes when one person is speaking, he says the same thing that his friend is going to say. When this happens, the friend might say, “You took the words right out of my mouth!”
Some people have lots of money because they were born into a very rich family. There is an expression for this, too. You might say such a person “was born with a silver spoon in his mouth”.
This rich person is the opposite of a person who lives “from hand to mouth”. This person is very poor and only has enough money for the most important things in life, like food.

North American back bears are shy animals. They are fearful by nature, and will usuallyrun away if they see or hear people. Because of this, it can be difficult for scientists to learnabout these animals.
In order to study black bears, researchers from New Jersey, USA, catch bears and usedrugs to help them go to sleep. Researchers then work out the size and the weight of the bear,take blood to test for diseases, remove a tooth and take it to the lab to find out its age. Fromthese studies,researchers want to find out how many bears live in New Jersey, how long theylive, and how many babies theyproduce.
But in Minnesota, USA, researchers study bears that are completely awake. The bears knowthe researchers' voices and they are not afraid of die research team. With the help of a few grapes
