Although Charles Darwin（达尔文） thought that trees are competing for survival of the fittest, Simard and her team have made a new discovery and showed just how wrong he was. In fact,the opposite is true: trees survive through their group work and support, passing around necessary nutrition (营养) like Nitrogen (氮) and carbon depending on who needs it.Nitrogen and carbon are shared through miles of underground fungi (真菌) networks, This makes sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.Simard talks about mother trees, These are usually the largest and oldest plants on which all other trees depend. These “Mother Trees” are connected to all the other trees in the forest by this network of fungi, and may manage the resources of the whole trees and plants in the forest. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down Mother Trees without paying attention to these highly complex tree societies or the networks on which they feed, we are reducing the chances to save the whole forest.We didnt take any notice of it Simard says sadly. Mother trees move nutrition into the young trees before dying, but we never give them chance. If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.36 . The underlined sentence the opposite is true in Paragraph 2 probably means that trees_.Acompete for survivalBprotect their own wealthCdepend on each otherDprovide support for dying trees37 . Mother trees are extremely important because they_.Alook the largest in size in the forestBpass on nutrition to young treesCseem more likely to be cut down by humansDknow more about the complex tree societies38 . The underlined word it in the last paragraph refers to_.Ahow tree societies workBhow trees grow oldChow forestry industry developsDhow young trees survive39 .

Last month Hong Kong officers found 131,000 kilograms of broken computers,TVs and phones sent from Japan.Things like these are called electronic waste,or ewaste. Dealing with them is not an easy job. Every time an old computer breaks down,it needs to be dealt with safely. What is worse,at present,broken computer parts are usually buried. It may be hundreds of years before they are really gone in the earth.Many places in China are polluted by ewaste. Guiyu in Guangdong Province is one of them. This town is named as “the ewaste capital of the world”. It has to deal with 1.5 million kilograms of ewaste each year,from which it makes 75 million yuan. But it comes at a cost.Many of the poisons in ewaste find their way into the environment. An environmental group has found the air,the earth and the rivers in Guiyu badly polluted.Luckily,the Chinese government wants to change the situation. This year,China passed a new environmental protection law. Computer companies like Lenovo and Dell will be asked to take back their old computers. Hopefully,the problem with ewaste will be solved in the near future.45 . The ewaste found in Hong Kong last month was from _.AFranceBJapanCGermanyDAustralia46 .

But it seems that besides wearing a mask (口罩), few of us know what has caused the smog and what to do to beat it.
