Artificial Intelligence(AI)is growing rapidly. We are living in a world that depends more and more on Al. AI is a group of technologies. It helps machines get, understand and use information to do tasks.

AI’s recent developments have got a lot of social attention. Some people have welcomed AI because it makes things possible. For example, AI will have a big influence on areas like medicine and engineering. But this attention has also produced a lot of fear. Especially many workers are worrying that AI could make them lose their jobs.

According to a recent study, nearly five percent of jobs disappear because of AI. In some industries, AI has already been doing the work that people used to do, such as assembling(装配)cars, digging the coal and lifting goods. Self-driving cars and trucks controlled by AI will also take away the driver's jobs in the future.

On the other hand, AI will also create many new jobs for people. More people will be needed to write programs for AI systems(系统)and they will set up and work on them too. Meanwhile, jobs that require(需要)feelings, excellent communication skills with people will not be replaced(取代)by AI. These include jobs in fields like teaching, nursing and personal training.

AI is here. It is changing how people live and work in many ways. That makes AI important to watch, not to fear.

1.Which of the following is true according to Paragraph One?

A.AI can get information for people.

B.AI can help machines understand orders.

C.AI will become less important in the future.

2.What can we know about AI?

A.People welcome AI because it makes things enjoyable.

B.AI will have a big influence on areas like medicine and teaching.

C.Some people don't like AI because they think it may make them lose jobs.

3.Who might be influenced by AI according to the passage?

A.Writers. B.Businessman. C.Workers of car factories..

4.Why will AI create new jobs too?

A.Because more programmers will be needed.

B.Because some jobs will he replaced by AI.

C.Because there will always he human nurses.

5.What conclusion can we draw from the passage?

A.AI should be stopped right now.

You're not the same person you were as a child. You're not even the same personyou were five years ago. We don't just mean your personality. While we'd love tostart a never-ending discussion over the “true self”,we're here to talk about thecells(细胞)in your body.

Do you know how your fingernails and hair are constantly growing and replacingthemselves? The same thing happens almost everywhere in your body. Your outerlayer of skin makes way for fresher skin, and inside your veins(血管),blood cells turn over to make wayfor fresh blood. It's probably no surprise that these types of cells are short-lived, even some of the mostseemingly permanent(永久的)parts of your body replace themselves over time-including your bones.

Strong as your bones might seem, the cells they're made of won't last a lifetime. Bones are masters at rebuilding themselves, which is why most broken bones can heal on their own into the right shape.

Bones have special cells called osteoclasts(破骨细胞)whose job is to break down bone, even if itisn't broken, and send the minerals into the blood stream. This may sound frighteningly like your bonesare wearing away, but your body knows what it's doing. As osteoclasts break down bone, osteoblasts(成骨细胞)build up new bone to replace the old. By the end of each year, about 10 percent of yourentire adult skeleton will have been rebuilt through this process.

If 10 percent of your bone breaks down every year, it must take about ten years to renew 100percent of your skeleton. That would be a great guess, and it lines up nicely with the medical myth thatthe human body's cells are fully replaced every seven years, but the body is a bit more complex. That10 percent is just an average-some bone grows faster than that, and some grows slower. While someparts of your bone will turn over quickly, other parts will stick around for decades. In fact, most bonecells could live as long as 50 years.

So before you get wrapped up in an identity crisis(危机)about the cells in your body disappearingon you, know that you can lose some hair and you can cut your nails, but the bones of you aren't goinganywhere-at least not very soon and not all at once.

1.Which of the following is TRUE according to the passage?

A. All the cells in our body are the same ones that we were born with.

B. Our blood cells are constantly growing and replacing themselves.

C. It must take about 10 years to rebuild 100 percent of our skeleton.

D. Osteoblasts can break down skin and also rebuild it over time.

2.The underlined words "wearing away" probably mean“__”.

A. building up B. taking off C. dying out D. turning on

3.What does the passage mainly talk about?

A. Our skeleton seems permanent but renews itself over time.

B. It is not surprising that some cells in our body are short-lived.

C. There are two types of cells in our bones: osteoclasts and osteoblasts.

D. We are not the same person we were five years ago because of personality.

Many of you may know that Jakarta is the capital city of Indonesia.1.Last month, Indonesia said that the country would move its capital from Jakarta to Kalimantan. This is big news for Indonesia.

The word capital comes from the Latin word "caput", meaning "head". It is no doubt the "head" of a country. The central government and important institutions (机构)are put there. 2. In English -language news reports, when you read "relations between Beijing and Moscow" ,it actually means "relations between China and Russia".3. Therefore, it is important to choose a good place for one's capital. In many countries, the capital is the richest city. This is because when a city becomes an important business center, it takes on a more important place around the world.

London, for example, has been the economic(经济)center of Britain for nearly 2,000 years, so people naturally chose it as the capital. 4.For example, Brazil's capital used to be Rio de Janeiro, which is a coastal city. Later the capital moved to the island city of Brasilia, partly because coastal cities can be attacked( 攻击) more easily.

In the case of Indonesia, the new capital was chosen in order to achieve development in different areas. 5. By becoming the new capital, it can expect faster economic growth.

A. But this will change soon.

B. That is how important the capital is.

C. Some countries have several capitals.

D. Kalimantan is an underdeveloped area.

E. Maybe we got the right ideas because of that.

F. Sometimes, capitals are chosen for safety reasons.

G. The leaders of a country usually work and live in the capital as well.
