As many as 10 of the 17 kinds of penguins(企鵝)may be in danger of disappearing. The number of penguins have decreased(減少) by 30% since 1987.
Penguins are black and white birds that live in the southern part of the world. They are common in South America,New Zealand,Australia and South Africa. Many live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly,but they are fine swimmers. Penguins eat fish and krill(磷蝦).
The warming of the earth is the decrease in penguin populations. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖). Besides,many adult penguins die of hunger.
Widespread(廣泛的) fishing,exploration for oil and oil leaks(漏) also make penguins be in danger. Poisonous organisms(生物) in ocean water are another danger. Penguins also have their enemies,including wild dogs,sharks,seals and sea lions.
News about penguins is not all bad,however. Several years ago,oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild. Now these South African penguins are reproducing in higher numbers than before the oil leaking

If you have a problem with speaking, you can do several things. Listen to English as much as possible. You can learn a poem(詩) or a song by heart. You can also learn more dialogues(對(duì)話). And practice speaking with your friends as much as you can.
Many people find it difficult to listen to English. The answer is to listen as much as you can. However, don’t do too much at one time. It is better to practice listening for five minutes every day. Don’t sit down and listen for an hour at a time. That’s too much! Do choose listening passages that are interesting and not too difficult. Choose(選擇) tapes(磁帶) on which the people speak clearly and not too fast. Take it easy, at first. Success with simple tapes at the beginning is the answer. Later on you can practice with tapes that are more difficult.
Finally, how can you learn to write well? How do you use little words like in, on, of and for? There are two answers to this. First, do some study with new words. Keep a list of verbs like look for, look after and so on. Second, read as much English as possible. There are many things that can’t be learnt. You must see them in books many times.

IQ(intelligence quotient智商)is a score that shows a person’s level of intelligence. People used to believe that some people are born with a high IQ and some aren’t.
1 a study by scientist at University College London has challenged(挑戰(zhàn))this idea. According to an article last October on the Journal Nature, scientists are beginning to think that our IQ is not a constant(不變的)score.
The scientists tested 33 healthy young people in 2004 between the ages of 12 and 16. Then they did tests again four years later, when the same people were between 16 and 20.
Scientists found big changes in the IQ scores between 2008 and 2004. Some 2and some fell 3 as many as 21 points.
To test whether these scores were meaningful, the scientists compared them with results from brain scans(掃描). They found that the IQ changes matched changes in the structure(結(jié)構(gòu))of the subjects’ brains. “A change in 20 points is a huge 4 ,” said Professor Cathy Price, who led the research. He said it could mean the difference between an average and a 5 person. The team has not found a clear cause for these changes. However, they say it is 6 that education plays a role in changing IQ. “Here we have shown that children’s 7 is likely to be still developing, ” says Price. “We have to be careful not to write off 8 performers at an early stage. In fact, their IQ may improve in a few more years. ”
1 A. And B. However C. Besides D. Though

When people visit Switzerland for the first time,they look with great interest,not only at the mountains but also at a type of clock—a Cuckoo-clock,on sale there.Cuckoo-clocks are very popular with tourists looking for a souvenir.A Cuckoo-clock has a small painted cuckoo that comes out near the top of the clock every half an hour and says,“Cuckoo”.Every hour it comes out and says “Cuckoo” the right number of times.It does not get a sore throat at midnight or mid-day! Children find these clocks wonderful.Adults gradually get annoyed because the cuckoo never misses an hour or a half hour,and this makes a short sleep in an armchair rather difficult.
In Europe,the cuckoo's call is a welcome sign that summer is on the way.This is the time when the mother cuckoo flies round,looking for a nest(巢)to lay one of her eggs.She chooses a nest belonging to another bird which already has eggs.When the nest is left unnoticed for a minute or two,the cuckoo rushes down,lays an egg and hurries off.In this way,she may lay her eggs in as many as four different nests.not one of which has been built by herself.
When a cuckoo egg hatches(孵化),the baby bird is bigger and stronger than the other nestlings.Step by step,it pushes other baby birds and any unhatched eggs out of the nest.In this way,it receives all the food from its foster-parents(養(yǎng)父母)and has a better chance of surviving.
