It is _____ to fly an airplane at three thousand miles an hour.
A

possible

B

likely

C

maybe

D

probable


参考解析

解析:
句意:飞机每小时飞行三千英里是可能的。possible,likely和maybe都有“可能的”的意思,但三者又有区别:possible表示某件事在行为者的力所能及的范围内,例如某人所能够做的、所能够成就的或所能筹划的事情;也可以表示某件事的可能性,这时说明的是事物的性能;likely所修饰的人或物的可能性已被断定,或被提出,或被坚持;probable表示某人做某事或事物的可能性时,具有推理的内涵。

共用题干Rockets in the SkyIf 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 wingsB:the air will become thickerC:the air will exert pressure on itD:the air will disappear in no time
