18.The world is being covered by plastic.In China,the amount of plastic waste rose into 14 million kilograms last year,but only about 9% was recycled.Over 1.32 million kilograms of plastic found its way into the world's oceans,which caused serious pollution.Luckily,researchers have found a special kind of bacteria which can help break down plastic recently. The bacteria are so small that we need a microscope (顯微鏡) to see them.They can "eat" plastic by changing its chemicals into something that will help them grow.The secret to this is enzymes (酶).Bacteria uses enzymes to cause chemical changes. In 2012,in the decaying (腐爛的) leaves,scientists discovered an enzyme called LCC that slowly broke down PET plastic.Most people know PET plastic.It is used in water and soda bottles.Most PET is thrown away,but even when it is recycled,it can't be made into new bottles.Compared with other 100,000 enzymes,it was the best at breaking down PET. To improve LCC,scientists studied the enzyme and the way it broke down the PET.By testing thousands of small changes to the enzyme,they found a new kind of LCC.It can be alive at higher temperatures,eat PET very quickly and make most PET plastic reusable.Scientists were satisfied with the result.When the environment was just right,the new LCC was able to break down 90% of the PET in just ten hours.The old enzyme took about 20 hours and only broke down half of the PET.

21."Save the whales!" That's what the picture on Jake Smith's bedroom wall said.Jake liked having a picture that said something important;that showed he cared.He just never expected to get a chance to save a real whale,one right in his own neighborhood. It was a Saturday morning when the newspaper first reported the whales' coming.A group of the animals were swimming close to the beach in Jake's hometown.All the local people rushed out to the beach to see them.They were expecting a beautiful show,better than a movie,but nothing they'd have to do anything about. Then one whale swam in their direction,directly towards land.It came in with the waves and when the waves receded,it stayed.Its huge body rested on the sand.Suddenly,Jake and his family and all the others were no longer sightseers (觀光者).They had to become rescuers (救援者).A few people ran towards the animal.They pushed and tried to force the whale back into the water,but it was no use. An animal rescue service team soon arrived in a truck with heavy lifting machinery,to help move the animal.Jake and his family couldn't do much on the beach,so they went back to their house and made sandwiches and hot tea for the rescuers.At least,Jake thought,they could help in some way. Back at the beach,they offered the food to the rescuers and were happy to see that it was needed.It was getting dark.Some people lined up their cars along the beach and shined the headlights on the sand.The rescuers would not give up.After trying many times they were finally able to lift the whale into the water.Everyone cheered when it headed out to sea.It swam out about a mile and then disappeared for a moment under the sea.Then,in what looked like a jump of joy,it rose high above the water -- a thank-you to those who had worked so hard to save its life.

24.Shyness is a kind of fear.People who are shy always worry too much about what people think of them or embarrassing themselves in some way in front of others. (1)
. ◆ Have a good posture(姿態(tài)) The way a person holds themselves says a lot about that person.People with sloped(傾斜的)shoulders don't think of themselves as important people. (2)
.By practicing a good posture,you will feel you have the ability to do things well. ◆ Increase your walking speed You can tell if a person is confident by the way he walks.People who walk in a slow way and look at the ground while walking usually have no confidence in themselves. (3)
