【文章內容簡介】 ss to modern water systems.[來源 :Zx x k .Co m] The researchers, led by Rohit Karnik, a professor ,decided to turn to trees for help because they were able to allow liquid to flow through while blocking out air bubbles(氣泡） . They began by cutting sections of tree bark from the branch of a white pine tree. The researchers then tested the wood’s filtering ability by pouring water containing red dye particles(染料顆粒 )of different sizes through. To their surprise, they found it was effective in trapping all the particles. Encouraged, the team did another experiment, this time with water containing bacteria. Sure enough, the bark held back 99%of the bacteria, allowing only 1% to flow through. Mr. Karnik said the bark was able to filter water containing much smaller particles. This means that it can be used to get rid of most of the bacteria. However, what troubles them is that tree bark cannot hold back viruses, which tend to be much smaller. Though the experiment is successful, we must remember one thing—the bark only works when damp. This means that before this natural filter can be put to practical use, the researchers will have to figure out how to keep the bark damp, or find a way to keep the bark’s great filtering ability even when it’s dry. But the study is not done. The researchers plan on testing other types of trees, including those flowering trees. They think those may be more effective in trapping smaller particles and even viruses. will the discovery affect the world? A. No harmful bacteria will be found in water. B. There will be no water pollution around the world. C. More pine trees will be planted around the world. D. Clean water will be more accessible in developing countries. problem troubles the researchers when using the trees bark as a water filter? A. Viruses cannot be prevented. B. Tree bark should be wet. C. It’s hard to remove air bubbles. D. Not all bacteria can be held back. does the team plan to do other experiments? A. To find other natural water filters. B. To improve the filtering ability of other trees. C. To find a way to keep the bark wet. D. To test the filtering ability of other trees. which column of a newspaper can we read this text? A. Culture.

But when people call us by cruel nicknames, it can be difficult to get them to stop. So what should you do? Ask your friends to stop. Maybe you tripped(絆倒） over your feet a few times, and your friends started calling you klutz, thinking that you don’t really mind. 37. Leave a nicknames behind. Sometimes, life gives us a chance to start fresh. 38. If you’re moving from elementary school to middle school, let your friends know that don’t want to go by your old nickname. Ignore those who call you by a nickname. If the kids calling you by a bad nickname aren’t your friends, you should do your best to ignore them. 39. It may be hard to pretend that it doesn’t hurt, but if you get angry or obviously upset, it will just encourage them to use the nickname all the time. 40. Remember that if you have a bad nickname now, you probably won’t be stuck with it. Just look at Elvis Presley! When he first started singing on stage, he wiggled(擺動） his hips so much that cruel critics and the audience nicknamed him Elvis The Pelvis. He never stopped wiggling. People soon found it impossible to ignore his talent and began to call him The King of Rock amp。 Roll. A. If it does bother you, tell them. B. Believe t
