Some people say they have a solution to the problems of car crowding and pollution. In many cities, hundreds of people 16 bikes to work every day. In the New York City, some bike riders have even founded a group: Bike for a Better City. They say if more people ride bikes to work, there would be 17 cars and less dirty air.
For several years this group has tried to gather help for bike riders. They want to have special roads 18 bikes only, because when bikes and cars use the same roads, there may be accidents. Bike for a Better City thinks if there were bike roads, more people would use bikes.
But no bike roads have been established 19 . Not everyone thinks it is a good 20 . Drivers don’t like it, and some shop owners don’t like it, 21 . And most people live 22 far from the city to travel by bike. Still, 23 has been done about it. On Saturdays and Sundays, the largest open park in New York is 24 to cars, and the roads may be used by bikes only, but the group still says this is not enough and goes on fighting 25 bike roads.

Ⅳ.阅读理解。（30分）
(A)
Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable(一次性的) toothbrushes, toothpaste, shampoo and slippers.
Many guests like the idea because they don’t have to bring their own. But if you travel to Beijing, remember to bring these things of your own. That’s because some hotels in Beijing have no longer provided guests with these disposables (一次性用品). Many disposable things are made of plastic. People throw them away after only using them once. It’s a waste of natural resources (资源) and is very bad for the environment.
In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of lunch bowls every year!
Plastic can take 100 to 400 years to break down. So the less plastic we throw away, the better environment we will have.
So, wherever you travel, bring your own things and use them again and again. Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life:
Use cloth shopping bags, not plastic ones.
After using a plastic bag, wash it out and let it dry. Then use it over and over again.
Do not use paper cups.
At your school canteen (餐厅), use your own bowls and chopsticks instead of disposable ones.
根据短文内容，判断正(T)误(F)。
( )26.Many guests like to use disposable things because they are very convenient (方便的).
( )27.Some Beijing hotels have no longer provided guests with free TV programmes.
( )28.Plastic breaks down easily.
( )29.After using a plastic bowl or a bag, we’d better throw it away, because it’s too dirty to use again.
( )30.We should use less plastic things and protect our environment.
(B)
Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage（损害；毁坏）. They can travel hundreds of miles in the wind before falling to the ground in the rain. And this “chemical rain” gradually（逐渐地）destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the country’s trees had been damaged by the year 1986.
Time and time again there are serious accidents that pollute the air. In 1986 there was a serious accident at a nuclear power station in Russia. A cloud of radiation flew across the whole Europe. It is said that 125,000 people died in Russia as a result of illness caused by this accident.
In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured (受伤的). Many of the injured lost their sight.

A.Chemicals in the smoke from power stations can’t travel far in the wind.

D.“Chemical rain” is bad for our environment.
( )33.In Germany, how many trees had been damaged by the year 1986?

( )34.What was the result of the accident that happened in Russia in 1986?

It’s important to learn things about protecting environment. Here’s a 4Rs rule for us.
·Reduce
If you want to reduce waste, you should use things wisely (明智的). A large number of trees are being cut down to make paper. If everyone uses paper carelessly and then throws it away, soon we would not have any trees left. Some other things are also being wasted, and people don’t know what to do with waste in big cities, so it’s necessary to reduce waste.
·Reuse
You should always think of reusing the usable (可用的) things before throwing them away. Give your clothes or things you don’t use to the poor. In a family, you may pass such clothes on to your younger brothers or sisters.
·Recycle
Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money, for example, cola cans are sent to a factory, where they’re smashed flat（压平）and smelted (熔化), and the metal things are made into new cola cans.
·Repair
If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it’s better for you to sell the old ones or give them to other people who can use them after doing some repair.
( )36.The “Reduce” rule mainly requires us _____.
A.to use things wisely B.to cut down many trees
C.to use paper carelessly D.to use more and more things
( )37.What’s the right order of recycling cola cans?
a.smash them flat b.collect the used cans
c.smelt them d.send them to a factory
A.a-b-c-d B.d-c-b-a C.b-d-a-c D.b-d-c-a
( )38.The “Reuse” rule mainly requires us _____.
A.to throw away the old clothes
B.to collect waste paper and soft drink cans
C.to use both sides of paper
D.to give the old but usable things to the poor
( )39.Which sentence is about the “Repair” rule?
A.When you leave a room, turn off the lights.
B.Take a cloth bag when you go shopping.
C.Don’t use plastic bags.
D.If your chair is broken, you can repair it.
