第4题:

Can animals be made to work for us?Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings.
They point out that at a circus,for example,we may see elephants,monkeys,dogs and other animals doing quite skillful things.Perhaps you have seen them on the television or in a film.If you watch closely,you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward.The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them.
Of course,as we know,dogs can be used to guard a house,and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near.But it may be possible to train animals to work in factories.In Russia,for example,pigeons which are birds with good eyesight,are being used to watch out for faults in small steel balls that are being made in one factory.When the pigeon sees a ball which looks different from others,it touches a steel plate with its beak.This turns on a light to warn people in the factory.At the same time a few seeds are given as a reward.It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour.

共用题干
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.

The cable-car in Singapore______.
A: takes visitors up to a mountain restaurant
B: takes skiers to the top of a ski-run
C: takes visitors to Sentosa
D: takes visitors to a high mountain

答案:C
解析:
选项A、B和D所涉及的情况都在瑞士,这在第一段可以看到。唯有C选项谈新加坡的情况,所以选项C是正确答案。


缆车是由马达带动的,没有驾驶员和轮子,也不受乘客控制。根据文中提示“The cable-car is really a carriage which hangs from a strong steel cable suspended in the air.”所以正确答案是A。


从上下来看,乘客所看到的惊险景色是因为“The car is suspended so high in the air that ships on the sea look like small boats , and boats like toys.”所以答案选B。


旅程虽短,但是“The cars in the air move in a leisurely manner, allowing passengers more than enough time to take in the scenery”,所以答案应该选A。


no less than意为“不比……少”,“和……一样”,所以正确答案应该选C。
