Comets(彗星) are parts of our solar system. Like the planets, they go around the sun.

But comets are not made of solid rocks like planets. A comet is a ball of dust, stones, and ice. Many people call comets dirty snowballs.

The “snowball” may be only a few miles across. But when the sun heats the “snowball,” much of it is changed to gases. The gases spread out and form the comet’s head, which may be thousands of miles across.

A comet moves fast in its trip around the sun. But when we see it, the comet does not seem to move. That’s because it is so far away. The moon moves fast, but when you look at it, you can’t see any motion(运动). That’s because the moon is far away.

Each year astronomers(天文学家) discover new comets. Some of them are seen only once. They make one trip around the sun and then go away out into space. The sun’s gravity cannot hold them.

Other comets, like Halley, keep returning. They have been captured by the sun. Halley’s earliest visit was probably 3,000 years ago. It may keep returning for another 3,000 years.

But every time a comet goes around the sun, the comet loses part of itself. Gases and dust are pulled out of the comet. That’s why Halley is now dimmer（暗淡的） than it used to be. Next time it visits us, in 2062, it may be even dimmer. Each visit it may get dimmer and dimmer, until it finally disappears.

1.What is this passage mostly about?

2.How does the writer help the reader understand what a comet looks like?

3.What is the most likely reason the writer wrote this passage?

Our sun is a star, and nine worlds (天体) move round it. Worlds like these are planets. But there are other stars, other suns, not only thousands of them, but millions of them. Do different stars have planets? We can see the planets round our own sun. but we haven’t been anymore. The stars are too far away from us. Stars give out light, but the planets don’t have any light of their own. So we can’t see them. They are too far, and too dark. Still, we can tell that some stars have planets. While a big planet goes round, it pulls its star to one side. And sometimes we can see this. Then we know that the star has a planet. For example, Barnard’s Star is a small red star. And it is the quickest star in the universe. But sometimes it moves slower, and then quicker again. We have known Bernard’s Star for many years, and now we are sure it has a planet.

Now many young people are traveling around the world on their own not because they have no one to travel with, but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier.“ The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.

Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything.” He said, “The feeling of having conquered something on my own is a major part of what drives me each day when I’m dealing with a difficult task.” “I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

The great 19th century explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”

1.Which of the following will Kristina Wegscheider agree with?

A. Traveling alone is a necessary experience for everyone.

B. It is more meaningful to travel in foreign countries.

C. It is comfortable to travel around without a friend.

D. Traveling abroad helps people to find new things.

2.Traveling alone is challenging because________________ .

A. you have to make things on your own

B. it is hard for you to prove yourself to others

C. you can only depend on yourself whatever happens

D. it will finally build your character

3.What can we infer about Chris Richardson?

A. He started traveling alone at an early age.

B. He was once shot in the arm.

C. He used to work as a salesman.

D. His website encourages others a lot.

4.What is the best title for the passage?

A. Travel Abroad          B. Travel alone
