Section A 26 Using a computer or smartphone at night can cause us to pile on the

15、pounds, new research has revealed. The study found a link between blue light exposure blue light is【 C1】 _by smartphones and tablets and increased hunger. It found that exposure to the light increases hunger levels for several hours and even increases hunger levels after eating a meal. Results of th

16、e US study show that blue-enriched light exposure, compared with【 C2】 _light exposure, was【 C3】 _with an increase in hunger that began 15 minutes after light onset and was still present almost two hours after the meal. Blue light exposure has also already been shown to decreased【 C4】 _in the evening

17、 increasing the risk of insomnia. Study co-author Ivy Cheung, of Northwestern University, in Chicago, said: “A single three-hour exposure to blue-enriched light in the evening【 C5】 _impacted hunger and glucose metabolism. “ “These results are important because they suggest that manipulating environm

18、ental light exposure for humans may represent a novel【 C6】_of influencing food intake patterns and metabolism.“ The study group【 C7】_10 healthy adults with regular sleep and eating schedules who received【 C8】_carbohydrate-rich meals. They completed a four-day trial under dim light conditions, which

19、involved exposure to less than 20 lux during 16 hours【 C9】_and less than three lux during eight hours of sleep. On day three they were exposed to three hours of 260 lux, blue-enriched light starting 10.5 hours after waking up, and the effects were compared with dim light exposure on day two. Ms Cheu

20、ng said more research is needed to determine the【 C10】 _of action involved in the relationship between light exposure, hunger and metabolism. A) exposure B) awake C) associated D) emitted E) related F) acutely G) comprised H) sleepiness I) agencies J) significant K) approach L) identical M) dim N) m

Recycling has become a part of American life. It also is an important part of the waste-processing industry. In fact, many cities and towns in

22、the United States now have recycling programs. To learn how such a program works, we will go to a recycling centre in the eastern state of Maryland. B) The recycle bin in the home or office is often the last stop for empty containers. But for papers, plastics, cardboards and cans, it is the beginnin

23、g of a trip thousands of kilometres long. Yehenew Gedshew directs a recycling centre near Washington, DC. “As long as people throw their trash, we have a job.“ His recycling centre processes about 35 tons of material an hour. How does it process that much every hour? Yehenew Gedshew says the busines

24、s is highly-organized. “First what happens is, dump trucks bring materials to our site. They dump it on the tipping floor. It goes to the first screen where the cardboard and the rest of the material is sorted out.“ The rest of the material goes on a belt that carries the glass and plastic to the la

25、st screening area(筛分区 ). The glass gets crushed and the plastic gets sorted and flattened. C) Local recycling programs often require people to separate plastics, papers and glass. But Yehenew Gedshew says sorters at his recycling centre do all that work. He says the centre ships most of its plastic

26、to a processing centre in North Carolina, more than 500 kilometres to the south. At that centre, mountains of bottles become piles of plastic. They are ready to be melted and shaped into something new. D) From the store to the recycling bin, and from there to just about anywhere you can imagine, pla

27、stic bottles spend a lot of time on the road. And so have we. We now go to Fayetteville, North Carolina. The city is home to the Clear Path Recycling centre. It is one of the largest plastic recycling centres in the United States. E) The Clear Path Recycling Centre receives 8 to 10 trucks a day. Tha

28、t means more than 18,000 kilograms of plastic every day. The goods come to the centre in large piles or bales, like the ones at the recycling centre in Maryland. F) Not far from the Clear Path Recycling is a huge storage area for the plastic objects. They enter the recycling centre to begin the proc

29、ess that will change them. “This is where the whole bottles enter the whole bottle wash. It s just like your front-end loading washing machine at your house. It s just a lot longer, and a lot bigger.“ G) Hot water washes paper labels off the drink bottles and removes dirt. The plastic is broken up i

30、nto what the plastics recycling industry calls “PET flake(PET碎片 ).“ Another centre will buy the flake to melt and mould into something else. H) Plastic bottles spend their lives on the move. Machines mould and fill them with our favourite drinks. When we are done drinking, machines destroy the bottl

31、es and make them into new bottles. Their journey never ends. But our trip has come to an end in Wilson, North Carolina. I) In our program, we have described the trip made by plastic bottles from stores to recycling bins and then to recycling centres. The bottles are then broken down into small piece

32、s, which are put into bags. Now, we will witness the rebirth of a plastic bottle. J) Mark Rath is a supervisor at Peninsula Packaging. At his business, pieces of plastic become products like carry-out trays at food stores and restaurants. Peninsula Packaging melts and flattens plastic so it can be s

33、haped and moulded. The process is complex. “We take the clear chips like this, and it goes into an oven, and it cooks for about 3 to 4 hours in that oven.“ K) The plastic cooks at almost 200 C. When the melted plastic comes out of the oven, it is made into carry-out trays or other food packaging. “W

34、e unwind the plastic into a very long oven where we heat it again, and then well form it in a forming station. Well follow it through and see what happens to it.“ What happens to the recycled plastic involves a vacuum, lots of pressure, and believe it or not more recycling. L) Mark Rath says all of

35、the plastics in this packaging centre become some kind of container in their next lives. “Thatll end up being a fresh-cut-salad base. Not sure where it goes, but itll end up some place with celery and carrots and tomatoes.“ It has taken several days, but a plastic bottle like the one we bought in Wa

36、shington, DC has now become a salad tray in North Carolina. M) Countless things affect the health of our environment. What we take from nature may not harm it as much as what we add to it. For years, many people have harmed the environment by throwing away plastic grocery bags. But in Washington, a

37、“bag tax“ has changed the behaviour of many people, and the way business affects the environment. N) The Anacostia River flows through southeast Washington into the better-known Potomac River. The Anacostia is often called the citys “other river.“ Tommy Wells is a member of the Washington, DC city c

38、ouncil. He is worried about the health of river. He notes that some people have called the Anacostia, one of the 10 most polluted rivers in the country. Mr. Wells says he was tired of seeing so many plastic bags in or near the river. “I wanted something that got into people s heads; not their pocket

39、s.“ O) Stores in Washington now require people to pay five cents for each disposable plastic bag. The money goes into the “Anacostia River Clean Up Fund.“ People who bring their own bag do not pay anything extra. Has the “bag tax“ helped? Bret Bolin is with the Anacostia Watershed Society, a group t

40、hat is working to protect the river. “In just about 3 and a half months of the bag fee, people were already reporting that they were seeing a lot less bags in the river and at cleanup sites than in past years.“ Councilman Tommy Wells agrees that the bag tax worked. “There was a 60 percent reduction

41、of the amount of bags that were pulled out of the river.“ The local government estimates that stores gave shoppers almost 300 million bags in 2009. Mr. Bolin says the bag tax caused the number to drop sharply. “And they were estimating something like 55 million being distributed in 2010, which is an

42、 80 percent reduction, which is amazing.“ 37 Bag tax has played a key role in reducing bags in and near the Anacostia River. 38 After the trunks bring in trash the first thing we need to do is sorting them out. 39 The Anacostia River is greatly polluted by many plastic bags and it worries Tommy Well

43、s a lot to see people just care about making money instead of environment protection. 40 The Clear Path Recycling Centre receives a large amount of plastic everyday. 41 Many things can be harmful to environment such as throwing away plastic bags but this behaviour has been changed due to the bag tax

44、. 42 Plastics at Peninsula Packaging will become different containers such as a salad tray, in many places across the country. 43 After hot water washes off labels and dirt, the plastic will be broken into small pieces waiting to be melted and molded into other things. 44 Plastic bottles spend their

45、 life on the move from the drink container to the recycling centre to be made into new bottles or other containers. 45 In a huge storage area the bottles will enter an enormous machine which looks like a big front-end loading washing machine in people s home. 46 Peninsula Packaging melts and flatten

46、s plastic in a big oven so it can be shaped and melded into new things like carry-out trays. Section C 46 Imagining being asked to spend twelve or so years of your life in a society which consisted only of members of own sex, how would you react? Unless there was something definitely wrong with you,

47、 you wouldnt be too happy about it, to say the least. It is all the more surprising therefore that so many parents in the world choose to impose such abnormal conditions on their children conditions which they themselves wouldn t put up with for one minute! Any discussion of this topic is bound to q

48、uestion the aims of education. Stuffing children s heads full of knowledge is far from being foremost among them. One of the chief aims of educations is to equip future citizens with all they require to take their place in adult society. Now adult society is made up of men and women, so how can a se

49、gregated school possibly offer the right sort of preparation for it? Anyone entering adult society after years of segregation can only be in for a shock. A co-educational school offers children nothing less than a true version of society in miniature. Boys and girls are given the opportunity to get to know each other, to learn to live to gather from their earliest years. They are put in a position where they can compare themselves with each other in terms of academic ability, athletic achievement and many of the extra-c
