China_is_going_green. In order to reduce air pollution and oilshortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
1.The author writes this passage mainly to________.
A.teach people how to drive a hybrid car

Vitamin B could help reduce the effects of the dangerous type of air pollution, according to a new study published on Monday. In the first study of its kind, a team of international researchers looked into the damage caused by one of the pollutants that have the severest impact on health—PM2.5.
They found that Vitamin B supplement could effectively reduce the impact of the tiny particles (颗粒)on the human body, although they stressed that the research was in its early stages. According to the WHO, 92% of the world's people are living in places where the PM2.5 level goes beyond the recommended level. So it’s urgent to find a solution to the problem.
According to this study, published in the PNAS, 10 volunteers were initially exposed to clean air and given a placebo (安慰剂)to check their baseline responses. The group then kept on taking placebos tor tour weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1,000 cars passed every hour. The bad air was delivered to the volunteers through an "oxygen type" face mask. The experiment was then repeated, with each volunteer taking a Vitamin B supplement daily, made up of 2.5mg of folic acid, 50mg of Vitamin B6, and l mg of Vitamin B12.
Vitamin B6 can be found in liver, chicken, nuts and other things, and Vitamin B12 in fish, meat, eggs, milk and some cereals. The researchers found that four weeks of Vitamin B supplements — the damage of PM2.5 effects by 28-76%. The results emphasized how prevention at an individual level could be used to fight against the damage of PM2.5, the researchers said.
1.What's the newly discovered effect of Vitamin B in Paragraph 1?
A. It can be used to replace other vitamins in our daily life.
B. It can help lower the air pollution level in the open air.
C. It can reduce the impact of PM2.5 on human bodies.

We’re drowning in plastic. If you want to reduce your own contribution to the plastic pollution problem, recycling might seem like an easy solution.
But what happens after you clean out those plastic containers and pour them into a recycling bin? Unfortunately, the outcome isn’t as rosy as many people think; recycling is unlikely to give plastic to-go containers new life. “Of all the waste produced in 2017, only 8.4% of it eventually got recycled. It’s not that consumers aren’t motivated to recycle or that they don’t have ready access to recycling programs; the United States simply doesn’t have the proper facilities (设施),” said John Hocevar, a marine biologist with Greenpeace USA.
A recent report surveyed the United States’ 367 materials recovery facilities—the facilities that sort our recycling—and found only plastic bottles were regularly recycled. The fate of most other types of plastic such as packaging usually ends up being buried or burnt.
Not all plastic is created equal. If you turn over a transparent plastic bottle, like those used to hold water, you’ll notice a number “1” inside a triangular recycling symbol. Non-transparent jugs, like the kind that hold milk, get a “2”. At materials recovery facilities, or MRF’s, plastics get sorted based on these numbers, which indicate how recyclable they are.
Numbers 1 and 2 are relatively recyclable. Recycling gets more difficult with higher numbers, called “mixed plastic”. This waste makes up around 69% of all the plastic we use. It’s much more expensive to process than numbers 1 and 2.
So what the United States needs is facilities equipped to process other kinds of plastic. But Hocevar came up with a different solution: “The really simple answer is that we have to stop making so much throwaway plastic.”
That said, is recycling worth it? For bottles labeled (贴标签) “1” or “2”, the answer is “yes”. There’s also a growing market for plastics labeled “5”. For other numbers, Hocevar’s answer was simple: a resounding (响亮的) “no” on numbers 3, 4, 6 and 7.
1.Which problem is the USA facing according to the text?
A.People don’t know the best way to recycle.
B.Ready recycling programs are not accessible.
C.People lack awareness about plastic recycling.
D.There isn’t suitable equipment for plastic recycling.
2.What may John Hocevar think of plastic recycling in the USA?
A.Productive. B.Promising.
C.Unsatisfying. D.Controversial.
3.What information can the numbers on plastic bottles convey?
A.Whether it is easy to recycle them.
B.The recycling technology they need.
C.They places where they were produced.
D.Which dustbin we should put them into.
4.What should we do with plastic according to Hocevar?
A.Give up the use of plastic.
B.Develop more cheaper facilities.
C.Only recycle plastics labeled 1 to 5.
D.Reduce the production of mixed plastic.

To pollute or not to pollute? That is the question. In order to survive, we all need to cause pollution. Factories that process the food we eat, clothes we wear, and cars we drive have to cause pollution. The environment has the ability to absorb our waste or the pollution, but its absorption ability has its limits. If the pollution level is higher than what the environment can cope with, then that's the time when pollution is bad.
If the pollution level becomes too high, human health can be affected badly. Then, the productivity level of the sick people is low and the economy suffers. The economy suffers not only because of the lost productivity of the people, but also because the government must pay for the damage the pollution has done to its people.
This is the reason why the government prefers taxation policy. Imposing(征收)a tax on firms that pollute the environment can be considered a good strategy, as long as the tax covers all the external costs or the cost of the damage the firm has created during production.
Taxation, if enforced(执行)really well, can make firms create a technology that may reduce pollution, if they find out that it will be cheaper than continuously paying the tax. The disadvantage of this policy, however, lies in the possibility that some big firms will find the tax cheap and then they will just produce more and pollute the environment more. If other small firms find the tax expensive, thus closing down, their production will be eaten up by those firms which can afford the tax.
Therefore, it is important that lawmakers in each country, when deciding to impose a tax on pollutant emissions, first review and analyze very carefully the real cost of the damage.
1. We can infer from the first paragraph that
A. for human beings pollution is unavoidable
B. it's not easy to figure out how bad pollution is
C. humans should reduce the use of everyday products
D. we can survive without causing pollution.
2.The underlined word "absorb" here refers to”____”.
A. reduce B. fit in
C. avoid D. deal with
3.What is the second paragraph mainly about?
A. The effects of pollution on human health.
B. The relationship between people and their government.
C. The effects of pollution on economic development.
D. The relationship between human health and economic development.
4.Which of the following can be the result of imposing a higher tax according to Paragraph 3 ?
A. Firms may reduce the prices of their products.
B. Firms may develop some environmental technology.
C.A big firm will be broken up into small firms.
D.A small firm will try to pass the tax on to consumers.
