答案：above all in a quiet neighbourhood 三、阅读理解 As we all know,trees are important to our life.They provide us with food,wood and most importantly,oxygen.Now there is one more thing we can add to this list- blocking out harmful bacteria in water. The discovery was made by some scientists and high school students who were seeking for a natural water filter(过滤器)一one that can help people in developing countries that don't have access to modern water systems. 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(气泡) They began by cutting 1.5-inch-wide sections of the 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()of different sizes through.To their surprise,they found it was effective in trapping all the particles.Encouraged,the team did another experiment 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 the 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. 1.How 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. 答案D

Levi Strauss was born in Germany in 1829. 2 .Before he moved to the West in 1853,Strauss worked in his brother’s dry goods business.This gave him a chance to produce his famous invention.During the Gold Rush,Strauss decided to move to the West to seek his fortune
