Coral reefs
For millions of years, coral reefs have provided homes and food for thousands of different living things. Fish and sea birds share the reef with other sea creatures. Now these beautiful places are in danger. 1. Scientists have found that people and pollution have ruined more than one-fourth of the earth’s coral reefs. Unless things change, all of the remaining reefs may die within your lifetime.
Some people think that coral is stone because of its rough, hard surface. But coral is an animal! Tiny polyps (水螅体) form the coral reefs. 2. These colours come from the algae (海藻) living inside the coral. Billions of coral polyps stick together. New ones grow on the dead corals. This happens year after year. Over time, the coral builds up a reef. The reef rises from the ocean floor until it almost reaches the sea’s surface. It takes coral 500,000 years to build a huge reef. 3.
The coral reefs have been harmed in different ways. People have broken off pieces of coral. They wanted to sell or keep them. To catch more fish, people have dropped sticks of dynamite (炸药) into the water. 4. Water pollution has encouraged overgrowth of the sea plants that grow near coral reefs. They block out the sunlight that the algae need. 5. Warm water kills the algae. When the algae die, the coral loses both its food and its color. The coral turns white and dies. Scientists call this coral bleaching (珊瑚白化). The bleached part of the coral reef cannot recover.
A. They come in many colours.
B. This has blown up parts of the reefs.
C. So are all the sea plants and animals that depend on them.
D. The worst problem is the heating up of the world’s oceans.
E. Coral reefs are experiencing a rapid increase in most locations.
F. However, it has taken human beings less than 100 years to destroy the reefs.
G. They cover less than 1% of the ocean floor, but support about 25% of sea creatures.

Some people make you feel comfortable when they are around. You spend an hour with them and feel as if you have known them half your life. 1..
Here are several skills that good talkers have. If you follow the skills, they’ll help you put people at their ease, and make friends with them quickly.
First of all, good talkers ask questions. 2. . One well-known businesswoman says, “At business lunches, I always ask people what they did that morning. It’s a common question，but it will get things going.” From there you can move on to other matters—sometimes to really personal questions. 3.. Second, once good talkers have asked questions, they listen to the answers .This point seems clear, but it isn’t. Your questions should have a point and help to tell what sort of person you are talking to. And to find out, you really have to listen carefully and attentively.
4. . If someone sticks to one topic, you can take it as a fact that he’s really interested in it. Real listening also means not just listening to words, but to tones of voice. If the voice sounds dull, then, it’s time for you to change the subject.
Finally, good talkers know well how to deal with the occasion of parting. If you’re saying goodbye, you may give him a firm handshake and say, “I’ve really enjoyed meeting you.” 5.. Let people know what you feel, and they may walk away feeling as if they’ve known you half their life.
A. Real listening at least means some things.
B. You can become a popular person.
C. Almost anyone, no matter how shy he is, will answer a question.
D. And how he answers will let you know how far you can go.
E. If you want to see that person again, don’t keep it a secret.
F. It’s polite to listen to others with a smile.
G. These people have something in common.

Two brightly colored butterflies have just flown by. They seems to be exactly alike, but actually one is a little larger than the other. 1 The smaller one has a wingspread of less than three inches and also a black line on its back wings.
At first sight, it is hard to tell them apart. Would you guess from this that they are different-sized butterflies of the same species? 2 If you said yes to either question, you would be wrong, for these look-alikes belong to quite different families.
The larger insect is the monarch butterfly (黑脉金斑蝶). As a baby insect, the monarch feeds on milkweed, which seems to give the monarch a disagreeable taste and smell. 3 Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone.
4 Birds would find this insect tasty, but because it looks like the monarch, birds keep away from it. The viceroy’s similarity to the monarch gives it some protection from its enemies and helps it survive.
There are other pairs of look-alike butterflies, bees and moths. In each case, one either has a disagreeable taste or smell, or can give a painful sting (叮咬). The larger is called the model. 5
A．The smaller insect is the viceroy (副王峡蝶), which feeds on the leaves of trees.
B．The larger insect has a wingspread (翼长) of up to four inches.
C．The bright coloring of the monarch acts as a warning sign to its enemy.
D．Birds protect their babies from eating such dangerous enemies.
E. The insect that imitates this model for protection is called the mimic（保护色）.
F. Or that they are different species of butterflies but close relatives belonging to the same family?
G. Do you like this kind of special species?

What do they really mean?
Food manufacturers and retailers are letting shoppers down. This is the view of the CWS, which has just brought out a new report.
According to the report, shoppers believe food labels(标签) because they think there are strict regulations in place. 1. So the food industry can get away with all sorts of tricky strategies to make products look bigger and sound better than they are.
The report has identified the different ways in which shoppers are misled. 2.____ Descriptions on packaging are sometimes inaccurate in an attempt to oversell the product. One example given in the report is the phrase "haddock fillets", used for a product that is in fact cut from big blocks of fish rather than individual slices.
3. These include "traditional", "wholesome", or "premium". The claim that a brand is "90% fat-free" hides the fact that it contains 10% fat, which above recommended levels. Phrases such as "free from preservatives" make a virtue out of a normal attribute of food.
Labels have a wide variety of text sizes on them. You sometimes need a magnifying glass to read the small print. 4.
Another deliberate type of misinformation lies in the image. Many pictures on packets use small plates to make the product look bigger. 5.
However, misleading messages on packaging could soon be a thing of the past. The CWS recently produced a code which, if used, would end the current inaccuracies and half-truths. It has called on the government to support it as a way of improving food standards.
A. Meaningless adjectives are often used to give a positive message.
B. An officer says the labels will receive very serious consideration.
C. Photographs are sometimes retouched(修饰) to achieve the same effect.
D. By contrast, the hard sell (强行推销) information is given emphasis.
E. The rules are, in reality, very weak at present.
F. This result has not pleased the food industry.
G. The most common of these is poor labeling.

As Nicole and Mike Zupan get closer to retirement, they worry about more than just covering their own living expenses for the next several decades.
1. He is autistic(患自闭症的) and may never be able to live on his own. Their idea of retirement is to live a quiet life close to their son. 2. They want to create a special needs trust to help pay for treatment and other expenses he might face as an adult.
“Because of our son’s needs, I guess I never really considered true retirement for us,” she says.
3. She is to attend college in a few years.
The Zupans’ ideal plan is for Mike, 60, to retire first, in five to seven years, and for Nicole, 52, to continue working for several years beyond that before she joins him in retirement.
But before they can get there, they want to pay off the $18,000 in credit card debt, partly because their son’s treatment is not covered by insurance. They have about $230,000 left on the mortgage(按揭) for their home in Fairfax County, Va., which they assess will take about 12 years to pay off. 4.
Matters are complicated by the fact that Nicole, who worked as a preschool teacher, is now unemployed while she recovers from foot operation. 5. Mike’s $120,000 income, which he earns as a government clerk, is enough to cover their basic living expenses. But Nicole wants to get back to work so the family could afford more treatment for Josef and pay down their debt faster. They also would be able to save more for their long-term goals, including retirement, their daughter’s college tuition and their son’s future living expenses.
A. Besides they have a $14,000 loan they used on home improvements.
B. It’s unlikely that Josef will go to college.
C. They’re also trying to save for their 14-year-old daughter, Elshaday.
D. They want to set aside enough money for their 15-year-old son, Josef.
E. It could be a few weeks before she can return to the workforce.
F. Can their retirement savings cover them?
G. He may need to move into a group home when he gets older.
