A Ride in a Cable-car
A ride in a cable-car is one of the exciting and enjoyable experiences a child can have.In
Switzerland,which is the home of the cable-car,it is used mostly to take tourists up the slope of a mountain,to a restaurant from which one can have a bird-eye view of the surrounding country, or to a top of a ski-run,from which,in winter,skiers glide down the snow covered the slope on skis .In Singapore,however,the cable-car takes one from the summit of a hill on the main island to a low hill on Sentosa,a resort island just off the southern coast.
The cable-car is really a carriage which hangs from a strong steel cable suspended in the air.
It moves along the cable with other cars on pulleys,the wheels of which are turned by electric motors. The cars are painted in eye-catching colours and spaced at regular intervals.Each car can seat up six persons.After the passengers have entered a car,they are locked in from outside by an attendant,they have no control over the movement of the car.
Before long,the passengers get a breath-taking view through the glass windows of the modern city,the bustling harbour,and the several islands off the coast. The car is suspended so high in the air that slips on the sea look like small boats,and boats like toys.On a clear day,both the sky above and the sea below look beautifully blue.
In contrast to the fast-moving traffic on the ground,the cars in the air move in a leisurely manner,allowing passengers more than enough time to take in the scenery during the brief trip to the island of Sentosa.After a few hours on Sentosa,it will be time again to take a cable-car back to Mount Faber. The return journey is no less exciting than the outward trip.

Which of the following about the cable-cars is true?
A: The cars move along the steel cable.
B: The cars are operated by a driver.
C: The cars are controlled by the passengers.
D: The cars move on wheels.

Rockets in the Sky
If someone asked you,"What color is the sky?"I expect that you would answer,"Blue."I am afraid that you would be wrong.The sky has no color.When we see blue,we are looking at blue sunlight.The sunlight is shining on little bits of dust in the air.
We know that there is air all around the world.We could not breathe without air.Airplanes could not fly without air.They need air to lift their wings.Airplanes cannot fly very high because as they go higher the air gets thinner.If we go far enough away from the earth,we find there is no air.
What is the sky?The sky is space.In this space there is nothing except the sun,the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space.They have looked at them through telescopes and in this way they have found out a great deal.The moon is about 384 ,000 kilometers away from the earth.An airplane cann't fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
I am sure that you are asking,"How does a rocket fly?"If you want to know,get a balloon and then blow it up until it is quite big.Do not tie up the neck of the balloon.Let go!The balloon will fly off through the air very quickly.The air inside the balloon tries to get out.It rushes out through the neck of the balloon and this pushes the balloon through the air.It does not need wings like an airplane.
This is how a rocket works.It is not made of rubber（橡胶）like a balloon,of course.It is made of metal. The metal must not be heavy but it must be very strong.There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket,the rocket is pushed up into the air.
Rockets can fly far out into space.Rockets with men inside them have already reached the moon.Several rockets,without men inside them,have been sent to other worlds much farther away.One day rockets may be able to go anywhere in the space.

When an airplane flies too high,______.
A:the air will be too thin to support its wings
B:the air will become thicker
C:the air will exert pressure on it
D:the air will disappear in no time

Californian Michael Schwabe said goodbye to the gas pump two years ago．He leased an electric car．Schwabe says he gets more out of driving an electric car than just a charge.
"With the price of gasoline and with the problems with clean air,it's important we get electric vehicles out on the road."
On California roads there are about two thousand electric cars．By 2003,ten percent of all new cars may be required to have zero emissions．This is a mandate automakers say it is way ahead of its time.
Gloria Bergquist of the Alliance of Auto Manufacturers says,"The technology(for zero emissions)isn't here yet;it still needs advancement in driving range to make it more appealing to a wider consumer audience."
Auto makers blame it on the batteries．Power runs out on most cars after about 70 miles．However,some cars can now go more than 100 miles on a charge．Batteries are expensive．Carmakers say there is nothing they can do about it.
Tim Carmichael of the Clean Air Coalition says,"The automakers have not built a vehicle unless required to do so,so it's very important for the state to stay committed to this program requiting automakers to build small amounts in beginning years and then the market will take off."

Right now the California Air Resources Board requires that a percentage of new cars sold should be free of emissions．What is that percentage?

A.1%．
B.5%．
C.10%．
D.100%.

Madrid was hailed as a public health beacon last November when it rolled out ambitious restrictions on the most polluting cars.Seven months and one election day later,a new conservative city council suspended enforcement of the clean air zone,a first step toward its possible demise.Mayor Jose Luis Martinez-Almeida made opposition to the zone a centrepiece of his election campaign,despite its success in improving air quality.A judge has now overruled the city's decision to stop levying fines,ordering them reinstated.But with legal battles ahead,the zone's future looks uncertain at best.Among other weaknesses,the measures cities must employ when left to tackle dirty air on their own are politically contentious,and therefore vulnerable.That s because they inevitably put the costs of cleaning the air on to individual drivers一who must pay fees or buy better vehicles一rather than on to the car manufacturers whose cheating is the real cause of our toxic pollution.It's not hard to imagine a similar reversal happening in London.The new ultra-low emission zone（Ulez）is likely to be a big issue in next year's mayoral election.And if Sadiq Khan wins and extends it to the North and South Circular roads in 2021 as he intends,it is sure to spark intense opposition from the far larger number of motorists who will then be affected.It's not that measures such as London's Ulez are useless.Far from it.Local officials are using the levers that are available to them to safeguard residents'health in the face of a serious threat.The zones do deliver some improvements to air quality,and the science tells us that means real health benefits-fewer heart attacks,strokes and premature births,less cancer,dementia and asthma.Fewer untimely deaths.But mayors and councillors can only do so much about a problem that is far bigger than any one city or town.They are acting because national governments一Britain s and others across Europe-have failed to do so.Restrictions that keep highly polluting cars out of certain areas-city centres,。school streets",even individual roads-are a response to the absence of a larger effort to properly enforce existing regulations and require auto companies to bring their vehicles into compliance.Wales has introduced special low speed limits to minimise pollution.We re doing everything but insist that manufacturers clean up their cars.
Which of the following is true about Madrid's clean air zone?

A.Its effects are questionable
B.It has been opposed by a judge
C.It needs tougher enforcement
D.Its fate is yet to be decided
