B E-WasteElectronic waste (e-waste) comes from computers, phones, e-books, cameras, fridges, TVs and so on. How much e-waste has been produced?There is too much e-waste on the earth. In the past ten years, 531.9 Mt (million metric ton) of e-waste has been produced. That’s as heavy as about 52,663 Eiffel Towers. What can we do with e-waste?E-waste is harmful to the environment. The three words are important: reduce, reuse and recycle. The following are some examples, Alex Li recycled about 136 tons of broken computers into ones that can be used again. Junichi Kawanishi turned about 79,000 tons of e-waste into Olympic medals. Weixiang EP Tech designed educational activities from e-waste for kids. Quadloop created solar lamps from e-waste. 16．From the passage, we can know e-waste doesn’t include ________. A．computers B．e-mail C．e-dictionary D．fridges 17．How much e-waste was produced in 2021 around the world? A．63.1Mt. B．59.4Mt. C．57.4Mt. D．53.9Mt. 18．What does the underlined sentence show? A．The Eiffel Tower is famous. B．The issue of e-waste is serious. C．The Eiffel Tower is so heavy. D．It’s not clear. 19．What did Alex Li do? A．He recycled computers. B．He created solar lamps. C．He made medals. D．He designed educational activities. 20．What can be inferred from the passage? A．E-books are not a kind of e-waste. B．E-waste doesn’t do harm to the earth. C．No actions have been taken to reduce e-waste. D．E-waste has been increasingly produced in recent years. C Trees are useful to man in three very important ways: they supply him with wood and other products; they give him shade; and they help to prevent droughts and floods. Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. 200 years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but without its trees, its soil became hard and poor. When the empire fell to pieces, the home country found itself faced floods and starvation. Even if a government realizes the importance of adequate supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with; and he can earn money by producing charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and take care of new trees. So unless the government has a good control system, or can educate the people, the forests will slowly disappear. This does not only mean that the villager’s sons and grandsons have fewer trees. The results are even more serious: for where there are trees their roots break the soil up — allowing the rain to sink in — and also bind the soil, thus preventing its being washed away easily; but where there are no trees, the rain falls on hard ground and flows away from the surface, causing floods and carrying away the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a useless desert. 21．What is the most important function of trees? A．Providing fuel. B．Offering shade. C．Preventing natural disasters. D．Providing charcoal. 22．What eventually happened to the rich, powerful country 200 years ago? A．Its people died of hunger. B．It fell to pieces. C．It became a giant empire. D．It built many ships with wood. 23．It is implied in the passage that the villager ________? A．wants a plentiful supply of trees. B．wants fire wood. C．wants to get money. D．is not aware of the environmental protection. 24．The role of trees is to ________. A．loose soil B．keep soil in position C．harden soil D．Both A and B 25．What does the passage mainly talk about? A．The three benefits provided by trees. B．Trees and soil conservation. C．The various uses of trees. D．The different attitudes of the government and the villagers toward trees. 3、 补全对话：本题共5小题，每小题2分，共10分。在七个选项中选择五个，有二个多余选项。 A: Hi, Li Ming. ____26____ B: I went hiking and picked rubbish along the way.

The villager wants wood to cook his food with; and he can earn money by producing charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and take care of new trees. (即使政府意识到树木充足供应的重要性，也很难说服村民看到这一点。村民需要木头来煮饭;他可以通过生产木炭或向市民出售头来赚钱。他通常太懒或太粗心去种植和照顾新树。)”及第五段“The results are even more serious: for where there are trees their roots break the soil up — allowing the rain to sink in — and also bind the soil, thus preventing its being washed away easily; but where there are no trees, the rain falls on hard ground and flows away from the surface, causing floods and carrying away the rich topsoil, in which crops grow so well (结果更加严重：因为树木的根系会破坏土壤，使得雨水得以渗透，还能固定土壤，防止土壤轻易被冲刷走；但是，在没有树木的地方，雨水落在坚硬的地面上，从表面流走，引起洪水带走肥沃的表层土壤，而农作物正是在这种土壤中生长良好。)”可推知，村民没有意识到环境保护。故选D。 24．细节理解题。根据第五段“for where there are trees their roots break the soil up — allowing the rain to sink in — and also bind the soil, thus preventing its being washed away easily; but where there are no trees, the rain falls on hard ground and flows away from the surface, causing floods and carrying away the rich topsoil (因为树木的根系会破坏土壤，使得雨水得以渗透，还能固定土壤，防止土壤轻易被冲刷走；但是，在没有树木的地方，雨水落在坚硬的地面上，从表面流走，引起洪水带走肥沃的表层土壤)”可知，树的作用是松土且能防止土壤流失。故选D。 25．主旨大意题。根据第一段“Trees are useful to man in three very important ways: they supply him with wood and other products; they give him shade; and they help to prevent droughts and floods. (树木对人类有三种非常重要的用途：它们为人类提供木材和其他产品；它们为人类提供阴凉；它们有助于防止干旱和洪水。)”可知，文章主要讲述的是树的重要作用。故选A。 3、 补全对话：本题共5小题，每小题2分，共10分。在七个选项中选择五个，有二个多余选项。 A: Hi, Li Ming. ____26____ B: I went hiking and picked rubbish along the way.

(您还做了什么来保护环境)”可知，横线上应是回答保护环境做的事，选项G“我们还种植树木并回收一些垃圾。”符合语境。故选G。 29．根据“Actually, everyone can do something for our environment. (实际上，每个人都可以为我们的环境做些事情)”“For example, we can use public transport and sort the garbage.
