1、大学英语六级模拟试卷 832及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write a short essay entitled On the Importance of Innovation. You should write at least 150 words following the outline given below. 1创新对于一个企业、一个民族的成长至 关重要 2但抄袭、模仿等现象屡见不鲜 3我认为 On the Importance of Inno
2、vation 二、 Part II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-4, mark: Y (for YES) if the statement agrees with the information given in
3、the passage; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Five Eco-crimes We Commit Every Day Ask yourself this: how green am I really? You might think you are doing your bit for the environment, bu
4、t even if you shun bottled water, buy local produce and reuse your plastic bags, chances are that you have some habits that are far more environmentally damaging than you realise. 1. Coffee Take coffee. The average cup of black filter coffee is in fact responsible, for 125 grams of CO2 emissions. Of
5、 this, two-thirds comes from production and most of the rest from brewing. Choosing the instant coffee reduces that figure to around 80 grams. Yet that still means a six-a-day caffeine habit clocks up more than 175 kilograms of CO2 each year. Thats the equivalent of a flight across Europe from Londo
6、n to Rome, say. Add milk, and the methane(甲烷 )produced by dairy cows means you increase your coffees climate-changing emissions by more than a third. It doesnt end there, though. The environmental group WWF has calculated that it takes 200 litres of water to produce the coffee, milk, sugar and cup f
7、or just one cup of regular takeout hot coffee. So if everyone ditched their pre-work coffee fix that would do wonders for the planet. 2. Toilet paper Then theres toilet paper. Like coffee companies, toilet paper manufacturers have long provided options for environmentally conscious consumers. Top of
8、 the list is 100 per cent recycled paper, which avoids much of the energy use and emissions associated with harvesting and processing new wood. Every kilogram of recycled tissue saves some 30 litres of water and between 3 and 4 kilowatt-hours of electricity. Since 1 kilowatt-hour of electricity is r
9、esponsible for around 500 grams of CO2, that means a saving of 1.5 to 2 tonnes of CO2 per tonne of tissue. Recycled toilet tissue is most widely used in Europe and Latin America, but even there it still only accounts for 1 in 5 rolls. In the US it isnt a common product. The average American gets thr
10、ough 23 toilet rolls each year, adding up to more than 7 billion rolls for the country in total. Of these, just 1 in 50 are from 100 per cent recycled fibres. As Greenpeace pointed out earlier this year, this not only wastes energy and water, it also puts additional logging pressure on old-growth fo
11、rest in North America, forests which play a vital role in supporting native biodiversity. The reason toilet roll made from new wood is preferred is quite simple: its long fibres produce the softest paper. Every time paper is recycled, the fibres become shorter, making for an increasingly rough bathr
12、oom experience. Recycled paper cant compete on softness so some use of new wood by the toilet paper industry may be inevitable. Sourcing Forest Stewardship Council(FSC)approved toilet tissue will help to ensure that any new wood fibres that are added to the mix have come from sustainable forestry pr
13、ojects that protect, rather than threaten, old-growth forest ecosystems. 3. Fast fashion Next on the list of everyday crime is fast fashion. In 1990, global textile production stood at 40 million tonnes. By 2005 that figure had risen to around 60 million tonnes. This surge in manufacture and consump
14、tion has been helped by fast-moving fashion trends and sweatshop price tags. As a result, much of the clothing we buy ends up being discarded long before it has worn out. In the UK, where the average item is worn for less than a third of its useful lifespan, more than a million tonnes of clothing ar
15、e thrown away each year. The bulk of it ends up buried in landfill sites. Even the global economic crisis appears to have had little impact on our love affair with fast fashion; UK clothing sales this summer were up 11 per cent on the same time last year. If we cant entirely kick the habit, we can a
16、t least dispose of the evidence in a greener way. At present, in the UK and US, only around a quarter of unwanted textiles are reused or recycled. Recycled textiles have many uses, from mattress(床垫 )fillings to bags and shoes, but the truly green alternative is reuse. The energy required to collect,
17、 process and sell a reused item of clothing is only 2 per cent of the energy required to manufacture a new garment. Every kilogram of virgin cotton preserved by reusing second-hand clothing saves 65 kilowatt-hours of energy, equivalent to about 32.5 kilograms of CO2. 4. Laundry Fast fashion has crea
18、ted textile mountains in many homes, yet the environmental cost of this excessive consumption has an even less conspicuous twin: the energy used to launder it all. Cleanliness has become a touchstone of domestic life since advertisers convinced us that our shirts must always be “whiter than white“,
19、our sheets should forever smell of spring flowers, and that to be dressed in freshly laundered clothes at all times is a badge of success. We live in a “wear once and wash“ culture. In fact, only about 7.5 per cent of the average laundry load in the UK is thought to be heavily soiled. Much of the re
20、st is made up of items that are stuffed into the washing machine simply because they are on the floor instead of in the wardrobe. This habit is shockingly wasteful in terms of water, detergents(洗涤剂 )and energy. One study found that over 80 per cent of the CO2 emissions produced during the life cycle
21、 of a single blouse arose from cleaning and drying it. The percentage can be even higher for items made of cotton, as they tend to require far more energy-hungry drying. It is easy to see how these emissions stack up. A full load in a washing machine uses around 1.2 kilowatt-hours of electricity per
22、 cycle and tumble drying clocks up a further 3.5 kilowatt-hours, resulting in over 2 kilograms of CO2 emissions per wash. With four or five loads per household per week, the total annual emissions from each home can easily pass the half-tonne mark. Thats a significant proportion of the 10-tonne annu
23、al emissions of the average European. Line drying, washing at lower temperatures and ensuring full rather than partial loads will all help to reduce laundry emissions. For the largest cuts, simply washing less frequently is the way to go. 5. Food wastage Of all the facets of overconsumption that pla
24、gue both human society and the global environment, food wastage is the most shocking. US households throw away around 30 per cent of their food, worth $48 billion every year. Similar levels of wastage are seen in Europe. In the UK, some 6.7 million tonnes of food is binned annually. Most of this joi
