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. Thy 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 cannot 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 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 fat 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 father away. One day rockets may be able to go anywhere in the space.

36. What color is the sky()？

A. It is blue .

B. It is white.

C. It is grey.

D. It has no color.

37. 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

38. A rocket can fly to the moon because ().

A. it looks like a balloon

B. it is much lighter than an airplane

C. it doesn’t have wings

D. it works like an untied balloon

39. Which of the following statements about a rocket is NOT true()？

A. It can fly when there is no air.

B. It can fly without wings

C. It is made of strong metal

D. it is propelled by burning gas inside it.

40. A rocket is pushed up into the air when ().

A. hot gas rushes out of its head

B. it is powered by gas

C. hot gas rushes out of its bottom

D. hot gas rushes out of its neck.

Kite

Kite flying is the sport of sending up into the air, by means of the wind, a light frame. covered with paper, plastic or doth. The frame. can be one of many different shapes and is attached to a long string held in the hand or wound on a drum. Kites have a long history practical application and many different types of kite have been developed to serve various purposes.

The ancient Chinese used bird-kites to carry ropes across rivers and valleys. The current folding kite which will dive excitingly is an improved type of such a kite. With its long flat body and single pair of bird like wings, it looks just like a large bird in the air. The modern version is usually made of tissue paper rather than the traditional silk.

Man-lifting kites were developed in ancient times, again by the Chinese, for getting information from walled cities and army camps. In fact, as recently as World War Ⅱ, German U-boats flew kites from their towers to lift people into the air to watch the land. These kites, which are no longer in existence, were made of lightweight cloth. They were much larger and stronger than the Chinese ones. Their design, however, was simply that of the cutter kite. Smaller in size, this type of kite is still very popular as a toy for children, being easy to make with a diamond-shaped frame, no wings and brown-paper covering.

Box kites are another type of kite found in toy shops today. The first box kite, named for its box-like body, was developed in the 19th century to test theories of flight and this type of cotton-covered kite greatly assisted the success of early airplanes. These kites are the ancestors of a heavier version of the box kite, called the double box kite, which consists of two main sections, placed side by side. Developed for the peacetime purpose of fishing in strong sea wind, it is the only modern kite described which has practical value. A long-lasting plastic material has to be used for this kite, which carries fishing lines.

The ancient Chinese bird-kites were usually made of light frames covered with ______.

A．silk

B．paper

C．cloth

D．plastic

People in the US can now carry an artificial intelligence (AI) around in their pocket, where it waits patiently to be told what to do.

Siri, an iPhone application that understands spoken commands and uses the web to carry them out,is a byproduct from a US military project to develop an artificially intelligent assistant.

Many people's experience of a "virtual assistant" may be limited to Microsoft's annoying classic Mr. Clippy. But in the week we spent together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop. It wasn't even stumped when I asked "do I need my umbrella today？" coming straight back with the local weather forecast.

A typical command might be: "Reserve a table for two at a good French restaurant in San Francisco." Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger.

In some ways Siri is just a fancy front-end to the 35 sites it can connect to, from taxi booking sites to movie review databases. But what's new is the way it can interpret the intentions of its master or mistress and use those sites to put them into action.

Doing that requires the ability to actually understand the meaning of words you use, not just passing on keywords blindly, says Siri co-founder Adam Cheyer.

"Book a four-star restaurant in Boston seems pretty straightforward," says Cheyer, "until you realise that Book is a city in the US, and Star is also a city in the US, and there are 13 Bostons, and Star is also the name of a restaurant."

To cut through what Cheyer calls the "combined explosion of interpretations", Siri uses your location, and the history of the commands you've given. It knows that "book" is most likely a command verb, unless you happen to be near the city of Book.

Siri attaches probabilities to the interpretation of each word and cross-reference(参照) with your location and other data, some of which you must provide yourself.

According to the passage, Siri is most probably ______.

A．still at its experimental stage

B．very popular with iPhone users

C．a US military assistant software

D．an artificial intelligence software
