When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.
Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.
The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.
This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻击) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attack attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.
小题1:What happens to people attacked by sharks?

A．Most of them because blind.	B．Most of them because of deaf.
C．Most of them died.	D．Most of them are still alive.

小题2:How do sharks find out about an unusual object according to the passage?

A．By biting.	B．By smelling.
C．By touching.	D．By killing.

小题3:Which sentence about sharks is true?

A．Sharks pull meat off bones when they eat.

B．Sharks might mistake humans for seals.

C．Sharks like to attack surfers because of their thick fat.

D．One bite from a shark is nothing serious.

小题4:What would the author write the passage mainly for?

A．To tell surfers to stay away from sharks.

B．To ask people to stop killing sharks.

C．To let us know the reasons for shark attacks on people.

D．To show that humans are much stronger than sharks.

It is true that people with better education are usually able to get better paying jobs. In other words, they have more chances to choose a good job while people with little or no education don’t. It seems that the purpose of education is to make people get jobs. But this isn’t accepted by all people.
Some people may think that a person should spend the best years of his life to get education only for a way of living. This was probably one of the earliest reasons of education. In fact, if education is just a way of making a living, people don’t need to spend so much time in school. People can get education for a living in a short time. Subjects like history and geography need not be taught to everyone. Even language and mathematics need not be taught in detail(详细地), either. Here it is clear that education is much more than teaching a man to get a way of living.
Education is well-rounded and it is mainly for improving a man. It is not only to teach him to speak, read and write, but also to develop his creative thinking and other abilities. After that, it is to make him a wise man and thankfully enjoy the achievements of human. Education is to make a man lead a better life. Educated people are expected to be able to listen to good music, read good books, watch plays and most of all take an interest in the world.
I would agree that making a good living is an important reason for education, but certainly not the most important or the main reason.
小题1:People with little education usually ____.

A．spend a long time in school	B．have a good chance to get a job
C．spend the best years to choose jobs	D．have fewer chances to get a good job

A．圆满的

B．崭新的

C．公平的

D．全面的

小题4:It is expected that educated people will be able to _____.

A．accept education as a way of living

B．take an interest in the whole world

C．develop their abilities to make plays

D．learn subjects like language and math

小题5:The passage mainly tells us that _______.

A．education should make a man improve

B．people can get education in a short time

C．people should be able to get better paying jobs

Televisions were among the most talked-about things at CES 2013—the 2013 International Consumer Electronic Show (国际消费类电子产品展销会) last week in Las Vegas, Nevada. They were bigger and better with some of the highest technology (技术). Some TVs used a new technology called OLED. They were bigger, thinner and lighter, offered better colour and were brighter than traditional TVs using LED.
Ultra High Definition TVs were also popular. Most of the TVs shown on the exhibition used 4k technology.
Smart TVs this year were smarter. Many offered technology that users have a more personalized （个性化的）experience. One such TV from TCL can know who is watching with the help of new technology. Then it can offer programmes according to the user’s usual interest. Another TV from Panasonic offers a similar personalized user experience.
Size also played an important part in CES 2013. TVs changed in size from big to bigger, with at least two companies —Samsung and Hisense —showing TVs that are 110 inches large on the exhibition.
The yearly CES is the biggest technology show in North America and one of the biggest in the world.
It’s a meeting of the brightest minds and the top leaders from many industries and those who want to know about the future.
