But even in develped cuntries, mst peple dn't g t wrk by bike. It's nt because bikes are expensive r peple are tired if they ride t wrk. It's because the number f cars n the rads becmes larger.

5 pllutin is still the mst serius. It's bad fr living things in the wrld. Many cuntries dn't let peple burn anything bad fr air in huses, and factries in the city.

Reading cmprehensin 1. Mark Twain nce said that everyne talks abut the weather, but n ne ever des anything abut it. This was true in his day. But it may nt be the case in tday's wrld. In fact, humans have fund many different ways t cntrl the weather. Clud seeding (云催化) is a kind f technlgy that can cntrl rain. It is dne by spreading chemicals like dry ice r silver idide(碘化银) inside f cluds, either by rcket r airplane. This changes the amunt f water inside the cluds, which helps t cntrl the amunt f rain, the time when it rains and even where it rains.
This technlgy has helped t slve drught. It has als played a key rle during imprtant events.

On the ther hand, n tw cluds are the same, s every new experiment intrduces new cnditins.
Using lasers(激光) t change the weather has been tested in a lab, and it has been fairly successful n a small scale. Scientists are still trying t figure ut hw t use it in the real wrld, but it culd be a new way t stp climate change.

Clze test 1. It's very imprtant that we all recycle. In nature everything is 1 again. Fr example, when an animal dies, it becmes 2 animal's fd. Nthing is wasted. But humans have created things like plastic bags 3 can't be brken dwn by nature. Our rubbish kills animals and 4 water and sil. 5 we cntinue making t much rubbish, the prblem will nly get wrse. If nature can't reuse the rubbish, we must recycle 6 . We shuld clean up the rubbish we've made because the nature can't.
Recycling is als the right thing t d fr anther reasn. The earth is rich in natural materials like water and trees, 7 these materials are nt endless. We use up ur natural materials much 8 than the earth is able t reprduce them. Fr example, each year we cut 9 mre than 6,000 square miles f frest, but it takes an average f 25 years fr a new tree t 10 . Recycling can help us save the earth, s let's take actin right nw.

But even in develped cuntries, mst peple dn't g t wrk by bike. It's nt because bikes are expensive r peple are tired if they ride t wrk. It's because the number f cars n the rads becmes larger.

Reading cmprehensin 1. Mark Twain nce said that everyne talks abut the weather, but n ne ever des anything abut it. This was true in his day. But it may nt be the case in tday's wrld. In fact, humans have fund many different ways t cntrl the weather. Clud seeding (云催化) is a kind f technlgy that can cntrl rain. It is dne by spreading chemicals like dry ice r silver idide(碘化银) inside f cluds, either by rcket r airplane. This changes the amunt f water inside the cluds, which helps t cntrl the amunt f rain, the time when it rains and even where it rains.
This technlgy has helped t slve drught. It has als played a key rle during imprtant events. Fr example, China used clud seeding in Beijing just befre the 2008 Olympic Games in rder t stp rain frm falling during the event. Hwever, scientists are still debating hw t use this technlgy. On the ne hand, it is believed that it might have side effects. Fr example, silver idide may be bad fr the envirnment. On the ther hand, n tw cluds are the same, s every new experiment intrduces new cnditins.
Using lasers(激光) t change the weather has been tested in a lab, and it has been fairly successful n a small scale. Scientists are still trying t figure ut hw t use it in the real wrld, but it culd be a new way t stp climate change. In additin t cntrlling rain, scientists have als tried t find ways t weaken strms and hurricanes(飓风). Scientists at the US Natinal Hurricane center Headquarters think it might be pssible t cntrl hurricanes by using lasers. Others believe that burning petrleum(石油) in a hurricane's path culd slw the strms dwn.

Reading cmprehensin 2. Hw d yu deal with plastic bags frm the supermarket? Thrw them away r recycle them? Hw abut eating them? The bags are n harmful t the envirnment. Humans and animals can safely eat them. Indian cmpany EnviGreen has made a bag with natural materials. It lks and feels just like plastic, but can be brken dwn(分解) easily.
Ashwath Hedge wh set up the EnviGreen cmpany spent fur years ding experiments with 12 natural materials. They include ptates, crn, vegetable il and bananas. He made the materials int liquid(液体) and used the liquid t make the bag. Althugh the EnviGreen bag is mre expensive than a cmmn plastic bag, it has many advantages. Accrding t The Wall Street Jurnal, it takes 1,000 years fr cmmn plastic bags t break dwn.
But an EnviGreen bag can naturally break dwn in less than 180 days. It als breaks dwn in less than a day in water, and in less than a minute in biling water. Hedge was happy t shw it in his interview; he put an EnviGreen bag in water and ate it with a smile. There are mre than 15, 000 tns f plastic waste in India every day. But nly 9, 000 tns are prcessed(处理). In China, 3 billin plastic bags are used every day. Maybe the EnviGreen bag culd be a slutin(解决方法) t the wrld prblem f plastic pllutin.
