1.Researchers in Britain are driving the environmental movement to a new level.A team from the University of Warwick has built what it calls the world's first completely environmentally friendly Formula Three racing car.The car is made mainly of renewable materials,like plants and vegetables.The structure around the car is made from natural plant fibers and potatoes.The steering wheel(方向盘) is made from root vegetables like carrots.The engine uses bio-fuel made from vegetable oil and waste chocolate.
The new racing car is extremely fast.The car has a top speed of two hundred fifteen kilometers an hour.And it can go from zero to ninety-five kilometers an hour in just two and a half seconds.
The racing car meets all of the Formula Three racing requirements except for its biodiesel(生物柴油)engine.
Automobile racing is one of the most widely watched sports in the world.But it is also considered one of the least friendly sports to the environment.Racing cars burn a lot of fuel,and create a lot of air pollution.In recent years,the racing industry has taken steps to protect the environment.More racing companies are now producing cars that use less energy.These cars produce less pollution than cars that depend on traditional fuel,like gasoline.
Last month,the new racing car was set to run in its first competitive race at the Formula Three Championship Final at Brands Hatch.It would have been the first biodiesel-powered car to race at Formula Three.Current Formula Three rules let only gasoline-powered car to compete.Officials needed permission from all of the Formula Three racers for the biodiesel-powered car to compete.They were unable to contact one of the drivers,so the new racing car didn't appear in the event.In test runs,the new racing car was the fifth fastest among the Formula Three race cars.Supporters are hoping to have the fuel problem solved in time to compete in the next season.
66.What's the second paragraph mainly about?A
A.What materials the new racing car is made of.
B.Why researchers built the new racing car.
C.The characteristics of the new racing car.
D.The process of the new racing car being designed.
67.According to the passage,theD of the new racing car doesn't meet the Formula Three racing requirements.
A.speed B.appearance C.weight D.engine
68.It can be inferred from the passage thatC.
A.the new racing car is the first environmentally friendly car
B.automobile racing could be forbidden in the near future
C.many people like to watch automobile racing
D.the new racing car will be allowed to compete in the next season of Formula Three racing
69.In recent years,racing companies are producing cars thatC.
A.burn more fuel B.go more quickly
C.produce less pollution D.cost less money
70.Why didn't the new racing car compete at the Formula Three Championship Final last month?B
A.Because the new racing car still needs testing.
B.Because officials needed each racer's permission but failed to contact one.
C.Because there're some technical problems to be solved.
D.Because few drivers think it is fast enough.

13.
Two recent studies might end the great grocery bag debate.The debates over which type of grocery bag is best break down into two issues:which are better for the environment,and which are better for your health.
The first study focused on the question of cloth bag contamination(传染).It's well-known that supermarkets offer many opportunities for people to pick up contaminated food:other shoppers contaminate shopping carts,and stockroom clerks contaminate containers.When shoppers put such things into cloth bags,they can contaminate the bag,and then wind up contaminating uncontaminated foods on their next shopping trip.Large numbers of bacteria were found in almost all bags.
Washing the bags might help,but researchers found that"reusable bags are seldom washed and often used for different purposes".
The second study should end the"use reusable grocery bags"argument.In the study,researchers evaluated(评估)the bags on a set of environmental standards,including global warming potential.The table below shows how many times that non-HDPE bags must be used in order to bring their global warming potential down to that of an HDPE bag.The first column,for example,shows that a paper bag should be reused three times to reduce its global warming potential to that of an HDPE bag,while you have to use an LDPE bag four times,a non-woven PP bag 11times,and a cotton bag up to 131times to achieve the same end.
So the conclusion seems clear:the traditional,thin plastic bag has better environmental performance and is likely to be quite safer for human health.
72.The researchers in both studies might agree thatC.
A.we should reuse our grocery bags as much as possible
B.cotton bags are environment-friendly when they are reused
C.plastic bags are good for the environment and our health
D.grocery bags,if washed,can reduce global warming potential
73.The underlined phrase"wind up"in Paragraph 2probably meansB.
A.give up B.end up C.pick up D.take up
74.What's the problem with cloth bags according to the first study?A
A.They are easily contaminated when reused.
B.They produce large numbers of bacteria.
C.They are poisonous and can pollute foods.
D.They need washing before being reused.
75.We know from the chart that in terms of reducing the global warming potential,A.
A.if an HDPE bag is used three times,a cotton bag should be used 393times
B.the more times HDPE bags are reused,the greater their global warming potential is
C.LDPE bags,when reused 9times,have a better effect than cotton bags reused 131times
D.non-woven PP bags,though reused 33times,work worse than paper bags reused 7times.

Type of carrier | HDPE bag (No secondary reuse) | HDPE bag (40.3% reused as rubbish bags) | HDPE bag (100% reused as rubbish bags) | HDPE bag (Used three times) |
