3、of fierce storms in the past ten years.Many scientists connected higher surface water temperatures resulting from global warming to greater and more damaging storms.Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol，an international agreement calling for

4、 industrialized nations to reduce their greenhouse gas emissions(导致温室效应的气体排放)，which are a main cause of global warming.“By refusing to sign the agreement，the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years

9、lion years ago. In fact，a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammalshorses，in this case，the last time the world heated up.The scientists used fossils to follow the evolution of horses from their earliest appearance

10、 56 million years ago.As temperatures went up，their size went down，and vice versa；at one point they were as small as a house cat，said Dr.Jonathan Bloch，curator(馆长)of the Florida Museum of Natural History，was quoted by the Daily Mail as saying.The scientists say that the current warming could have th

11、e same effect on mammals，and could even make humans smaller.“Horses started out small，about the size of a small dog like a miniature schnauzer(雪纳瑞犬)Whats surprising is that after they first appeared，they then became even smaller and then dramatically increased in size，and that exactly corresponds to

12、 the global warming event，followed by cooling.It had been known that mammals were small during that time and that it was warm，but we hadnt understood that temperature specifically was driving the evolution of body size.”Dr.Bloch said in the Science journal.5How did the scientists find out the evolut

13、ion of horses?ABy using fossils.BBy following the horses.CBy heating up.DBy studying cats.6According to the passage，which of the following sentences is NOT true?AGlobal warming has happened more than once.BThe Earth heating up was connected with the size of horses.CHorses first appeared on the Earth

15、ida and NebraskaCHorses used to be like catsDDr.Jonathan BlochCA town in Oxfordshire has become the first in the UK to have biomethane (生物甲烷) gas generated from human waste piped to their homes for gas central heating and cooking.Up to 200 families in Didcot now receive the gas via the national gas

16、power system.Head of energy and technology at British Gas，Martin Orrill，said customers wouldnt notice any difference as the gas is purified (提炼)to the highest standard and has no smell.The gas is produced at a sewage (污物)treatment works plant in Didcot.The entire process takes only less than three w

17、eeks，with the sewage being collected and sent first to settlement tanks.The solid waste material is then fed into digesters，where anaerobic bacteria(厌氧菌)digest the sewage，with the aid of enzymes (酶) to speed up the process.The digestion process produces methane，which can be burned to drive machines

18、to produce electricity，or can be purified and fed into the gas network and piped to homes and businesses.British Gas says supplying the gas rather than electricity is far more efficient since around twothirds of the energy is lost in producing electricity.Partners in the Didcot project，British Gas，S

19、cotia Gas Networks，and Thames Water，all hope to expand the process to other towns，and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned.One of these projects，in Manchester，could be supplying 500 homes with biomethane by mid next year.Anothe

20、r British Gas project in Suffolk will provide gas from digestion of brewery wastes to around 235 families.The Didcot project cost 2.50 and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies.An EU directive means the UK must ensure at least

21、15 percent of its energy is from renewable sources by 2020.The UK produces about 1.73 million tons of sewage annually.If all sewage treatment works in the UK were fitted with the technology，they could supply gas for up to 350，000 families.9Which of the following is TRUE of the biomethane gas?AIts ma

22、inly made from rotting plants.BIts an environmentally friendly gas.CIts production process is too long.DIts easily recognized by the customers.10What is the function of the enzymes?ATo digest the solid waste material.BTo help get rid of anaerobic bacteria.CTo help purify the biomethane.DTo speed up

23、the digestion process.11The last three paragraphs mainly show that_AUK government supports the biomethane projectsBthe biomethane projects are very costlyCthe biomethane projects still face many barriersDthe biomethane projects are promising12. What is the text mainly about?AComputer science.BEngine

24、ering.CEnergy.DBusiness.DAsk someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need.We are dealing with t

25、he results of that overconsumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place. The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical households waste in the UK. In

26、many supermarkets nowadays food items are packaged twice with plastic and cardboard.Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to c

27、ause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need.However, a few of them are coming round to the ide

28、a that this cannot continue, encouraging customers to reuse their plastic bags, for example. But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially

29、true of food.But it also applies to a wide range of consumer products, which often have far more packaging than necessary. There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the wastefulness of our consume

30、r culture, but we have a mountain to climb.13What does the underlined phrase“overconsumption” in Paragraph 1 refer to?AUsing too much packaging.BRecycling too many wastes.CMaking more products than necessary.DHaving more material than is needed.14The author uses figures in Paragraph 2 to show _Athe
