5．Drive through any suburb in the U．S．Today，and it's hard to miss the bins that have become companions to America's trash cans．Recycling has become commonplace，as people recognize the need to care for the environment．Yet most people's recycling consciousness extends only as far as paper，bottles，and cans．People seldom find themselves facing the growing problem of e-waste．
E-waste rapidly increases as the techno-fashionable frequently upgrade to the most advanced devices，and the majority of them end up in landfills（垃圾填埋地）．Some people who track such waste say that users throw away nearly 2million tons of TVs，VCRs，computers，cell phones，and other electronics every year．Unless we can find a safe replacement，this e-waste may get into the ground and poison the water with dangerous toxins（毒素），such as lead，mercury，and arsenic．Burning the waste also dangerously contaminates the air．
However，e-waste often contains reusable silver，gold，and other electrical materials．Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals，which can destroy ecosystems．
A growing number of states have adopted laws to ban dumping（傾倒）e-waste．Still，less than a quarter of this refuse will reach lawful recycling programs．Some companies advertising safe disposal（處置）in fact merely ship the waste to some developing countries，where it still ends up in landfills．These organizations prevent progress by unsafely disposing of waste in an out-of-sight，out-of-mind location．
However，the small but growing number of cities and corporations that do handle e-waste responsibly represents progress toward making the world a cleaner，better place for us all．

25．What can we infer from the first paragraph？A
A．Many Americans now have access to recycling bins．
B．E-waste cannot be put into trash cans in the U．S．
C．Most Americans have realized the dangers of e-waste．
D．Most of America's trash cans are made of recycled material．
26．What can best replace the underlined word"contaminates"in Paragraph 2？A
A．Pollutes．    
B．Heats．    
C．Absorbs． 
D．Reduces．
27．How does the author feel about burying e-waste in landfills？B
A．It's important．  
B．It's unsafe．
C．It's acceptable．
D．It's uncommon．
28．What's the author's purpose in writing this text？D
A．To tell us how to recycle e-waste．
B．To talk about the future of e-waste．
C．To discuss if it's necessary to recycle e-waste．
D．To encourage us to deal with e-waste properly．

5．From ancient times，people have always asked the question：what is the essence of our life？Well，in my opinion，life is a journey which （61）is（be） full of beautiful flowers and big stones．
Since we were born，we have been destined（注定） to experience happiness and sufferings in our whole life．Many great men have said human beings are equal．However，Aristotle didn't think so．He said some men were born for slavery and others for（62）ruling（rule） others．As to these two opposite view points，I agree with the first and believe we should make （63）our efforts to make our life（64）meaningful（meaning）．
When I was 8years old，I started to go to school with my cousin，（65）who did well in study in our class．On the contrary，my ability to study was not as good as his，so I was （66）confused（confuse） and disappointed with myself．At home，I chatted with my mother．She told me it was normal for me （67）to come（come） across difficulties in studies（68）and that I should try to find good learning methods that were suitable for me．
Then I began to have classes and do homework carefully，so I succeeded in my study and I （69）was admitted（admit） to the famous YaleUniversity at last．（70）In conclusion，challenges and difficulties are like big stones in our life，and we should overcome them with confidence and hard work．
