All plant cells are capable of taking up（吸收）water. Even dead ones do to a certain degree. Absorption（吸收）of water by dead cell walls makes wood become larger.
In common land plants, the living cells of roots take upmost of the water. Land plants without roots do exist, however. Those greenish-yellow lichens（苔藓）you see on rocks in the high mountains have no roots. Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots.
Even among the flowering plants, one finds rootless forms. These flowering plants are “the higher plants” because they evolved（进化）recently and are thus considered higher on the evolutionary scale（进化度）.
In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water only from the dew（露水）it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies.
In the southern United States and in Puerto Rico, one sees bromeliads growing high above the streets on the insulation（绝缘物）of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.Wood becomes larger because of .

Once you’ve tasted the joy and freedom of an all-access backstage pass, sitting in the balcony（楼厅） far from the stage has little attraction. In March of 2008, I had the opportunity to tour with a band. The experience was eye-opening.
I hadn’t realized how many misconceptions I had about the lifestyle of a world-class musician. Such a life is not as great as it appears. In fact, some aspects are extremely tedious. Hours and hours are spent waiting. The musicians wait for their transportation; they wait for the sound check; they wait to perform. After the show, they wait for the crowds of fans to go away.
When the musicians are not waiting, they are traveling. Sometimes the travel itself can seem attractive and exciting, with the limousines（豪华轿车） and the first-class seats on the plane. However, even these luxuries cannot make up for long, boring hours on the road or in the air. Basic needs are all but ignored. Late-night shows and early wake-up calls make them know the preciousness of sleep. The demanding travel itineraries（行程） and show schedules make regular meals impossible.
In spite of the sacrifices, life on tour has its advantage, at least for the talent. A support team generally travels with the band, with at least one person dedicated to meeting the musicians’ needs at all times. The musicians are expected to perform at the shows, but they are not expected to manage any detail of their lives. When I was with the band, I poured glasses of grapefruit juice, made sandwiches, prepared dressing rooms, and performed all kinds of routine work, such as buying toothpaste and getting money from the ATM. In addition, efforts are made by promoters to keep the musicians happy. Most places offer private dressing rooms for the musicians. There is also usually a green room, a room that is large with comfortable furnishings where the band can visit with friends and family while waiting to go on stage. Before the band goes on, their families and friends file out into the auditorium and find their seats. The house lights go dark and curtain rises. When the lights flash on and the band starts playing, the scene is magical. A behind-the-scenes view makes the experience even more spectacular.The underlined world in paragraph 2 probably means _____.
| A．exciting | B．boring | C．reasonable | D．ridiculous |
We can infer from the third paragraph that _____.
| A．good arrangements always make the trips comfortable and pleasant |
| B．most musicians would rather travel long distance than wait |
| C．most musicians ignore their basic needs because the travel is too luxurious |
| D．the lack of sleep and irregular meals seem to be a part of the life of musicians |
Which might be the best title for the passage?

| C．My Part-time Job. | D．How to Make Musicians Happy. |
My teenage son Karl became withdraw after his father died. As a single parent, I tried to do my best to talk to him. But the more I tried, the more he pulled away. When his report card arrived during his junior year, it said that he had been absent 95 times from classes and had six falling grades for the year. At this rate he would never graduate. I sent him to the school adviser, and I even begged him. Nothing worked.
One night I felt so powerless that I got down on my knees and pleaded for help. “Please God, I can’t do anything more for my son. I’m at the end of my rope. I’m giving the whole thing up to you.”
I was at work when I got a phone call. A man introduced himself as the headmaster. “I want to talk to you about Karl’s absences.” Before he could say another word, I choked up and all my disappointment and sadness over Karl came pouring out into the ears of this stranger. “I love my son but I just don’t know what to do. I’ve tried everything to get Karl to go back to school and nothing has worked. It’s out of my hands.” For a moment there was silence on the other end of the line. The headmaster seriously said, “thank you for your time”, and hung up.
Karl’s next report card showed a marked improvement in his grades. Finally, he even made the honor roll. In his fourth year, I attended a parent-teacher meeting with Karl. I noticed that his teachers were astonished at the way he had turned himself around. On our way home, he said, “Mum, remember that call from the headmaster last year?” I nodded. “That was I. I thought I’d play a joke but when I heard what you said, it really hit me how much I was hurting you. That’s when I knew I had to make you proud.”By saying “Karl became withdrawn”, the author means that the boy changed entirely and _____.

Did you ever look up at the moon and think you saw a man’s face there? When the moon is round and full, the shadows(影子) of the moon mountains and the lines of the moon valleys sometimes seem to show a giant nose and mouth and eyes. At least, some people think so.
If there were a man on the moon—instead of mountains and valleys that just look like the face of a man—what would he be like?
He would not be like anyone you know. He would not be like anyone anybody knows.
If the man on the moon were bothered by too much heat or cold the way Earth people are, he could not stay on the moon.
The moon becomes very, very hot. It becomes as hot as boiling water. And the moon becomes very, very cold. It becomes colder than ice.
Whatever part of the moon the sun shines on is hot and bright. The rest of the moon is cold and dark.
If the man on the moon had to breathe to stay alive, he couldn’t live on the moon because there’s no air there. He’d have to carry an oxygen tank, as astronauts do. There’s no food on the moon, either. Nothing grows—not even weeds（grass）.
If the man on the moon liked to climb mountains, he would be very happy. There are many high places there, such as the raised land around the holes, or craters(火山口), of the moon. Some of these rims are as tall as Earth’s highest mountains.
But if the man on the moon liked to swim, he would be unhappy. There is no water on the moon—just dust and rock.
When you think of what it’s like on the moon, you may wonder why it interests our scientists. One reason is that the moon is Earth’s nearest neighbor—it is the easiest place in space to get to.
Going back and forth between the moon and Earth, astronauts will get a lot of practice in space travel. Things learned on moon trips will be of great help to astronauts who later take long, long trips to some of the planets.
Scientists are also interested in the moon because it has no air. The air that surrounds Earth cuts down the view of the scientists who look at the stars through telescopes. A telescope on the moon would give them a clearer, closer view of the stars.（words: 411）What is the reason why our scientists are interested in the moon.?
| A．The moon is beautiful. |
| B．The moon is different from the earth. |
| C．The moon is Earth’s nearest neighbor—it is the easiest place in space to get to. |
| D．The moon is the easiest place in space to get to and it has no air, unlike Earth. |
The underlined word “rim” in the Paragraph 8 means _________ .

| B．There may be human beings on the moon. |
| C．If there were a man on the Moon, there would be many similarities between the man on the Moon and on the Earth. |
| D．A telescope on the Moon would help scientists have a clearer, closer sight of the stars. |
Everyone has got two personalities(性格)—the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behavior, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to upset people, so you never express your real feelings. You’re quite shy and you aren’t very confident.
If you sleep on your stomach, you are a rather secretive(不坦率的)person. You worry a lot and you’re always easily upset. You’re very stubborn, but you aren’t very ambitious(有雄心的). You usually live for today not for tomorrow. This means that you enjoy having a good time.
If you sleep curled up(卷曲), you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive（提防的）. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.
If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel anxious, but you don’t often get depressed（压抑）. You always say what you think even if it annoys people.（words: 278）According to the writer，you naturally show your secret and real personality _______.
| A．only in a normal night |
| B．only when you go to sleep |

Memory, they say, is a matter of practice and exercise. If you have the wish and really make a self-effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.
Sometimes you remember things that did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remembered locking it carefully the night before.
Memory “trick” works the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber(理发师) shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.
We always seem to find something funny in incidents（小事） caused by people’s forgetfulness or absent-mindedness(心不在焉). Stories about absent-minded professors have been told for years, and we never got tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny.
