Article: In the universe,as we all know,there is the sun,the moon,the earth and a good manystars.Through our geography lessons,we know the earth goes around the sun,and the moon goes around the earth.We have day and night because the earth keeps turning all the time.When our part of the earth turns to the sun,it is day.When our part of the earth turns away from the sun,it is night. Just because the moon is closer to the earth than the sun, it looks much bigger than the sun. Big things will look smaller when they are further, and small things also look bigger when they are nearer. The sun is big enough to give out very strong light. The moon can't give any light at all, but it looks quite bright, too. Why? In fact, the light from the moon comes from the sun. The moon looks much bigger and brighter than the stars. But actually   the stars are much bigger and brighter than the moon.They look smaller than the moon also because they are further away from the earth. There are many other planets in the universe. But of all the planets, only on the earth there are living things and people can only live on the earth, too. But at 9:00 a.m. on October 15th,2003, Chinese pilot Yang Liwei was sent up to space.

Q: Read the following article and answer the question. Article: What do you do if you are in trouble on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane. Body signals Pilots from different countries understand body signals if they have the correct training, When you wave your arms up and down in a straight line, it means, "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side. Smoke signals The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a tire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke. Ground-to-air signals It's a good idea lo build some signals, too. Use large pieces of wood to make the symbols  . If you can't find any wood, use earth. Some useful symbols are: F "I need food and water" II "I need medicine." I "I am badly hurt." X "I am unable lo move from here." Pilots' replies If the pilot lowers the plane's wings from side to side, this means: "message received and understood" (At night, the pilot flashes the plane's green lights.) If the pilot flies the plane in a clockwise circle, this means "message received hut not understood" (At night, the: pilot flashes the plants red lights.) However, there is no signal which means "message not received. Question: From the passage we know that   _  . Answer:
A: light smoke can be seen easily if the ground is dark.

Q: Read the following article and answer the question. Article: Soon computers and other machines will be able to remember you by looking at your eyes! The programme works because everyone's eyes are different. So in the future you won't have to remember a number when you want to use a machine or take money out of a bank. You'll just have to look at the machine and it will be able to tell who you are. The eye-recognition  programme is tested in shops and banks in the USA, Britain and Italy. Scientists are working on other systems, such as knowing you from the shape of your face or hand or even your smell! And machines can already tell who you are from your voice or your fingerprint . But eye-recognition will replace other ways of finding out who you are. It is better, because your eyes don't change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the programme can be up to 94% correct, depending on how good the technology is. In Britain, it was found that 91% of people said that they liked the idea of eye-recognition. ,. Question: Which recognition technology is already in use? Answer:
A: Remembering fingerprints or voices.
