To prevent these difficulties, a dam may be built across the river. This will store water for dry seasons, and in wet seasons it will prevent the flooding of the land. A great lake will, no doubt, be formed behind the dam, and this may mean that houses and fields will be covered with water. Most people will accept that and will be ready to move to other places. Then the country can have the right amount of water at all times; more crops will be grown, there will be more food for everyone, and there will be no more floods.
Dams have been built for centuries in different parts of the world. Modern dame are usually built of concrete(混凝土)but earth dams were used in India and Sri Lanka about 2500 years ago. There was another across the River Tigris very long ago, and large numbers of irrigation canals were made in Iraq to irrigate the land. The Romans were great dam-builders and there was also a famous dam at Ma’ rubin Arabia.
We cannot use sea water for irrigation; the salt will not allow the crops to grow. Fresh water is always needed, and it is very difficult and costly to make fresh water from sea water. This is done in a few countries, but the fresh water is for drinking. There is not enough at present for irrigation. Perhaps a scientist will one day invent a cheaper way of producing fresh water from the sea.

The bones of great metal ships, unlike the wooden vessels of old, survive the destruction of the sea long enough to become home and harbor for underwater life of all kinds. Shipwrecks(残骸) often provide the only hard surface and structure at the sandy bottom of the sea, something many sea creatures need.
The ship has been underwater for only five days. Its surface is still clean. Six weeks later, the wreck is covered with a slimy layer of algae(海藻), but it is still recognizable as a ship. Soon, animals that need to attach themselves to a hard surface, like the feather duster worms, make the wreck their home.
In warm waters, coral polyps(珊瑚虫) settle on the wreck and begin the process of building a rock-like crust on the ship. Small fish are attracted on all of these creatures. Larger fish come to feed on these small fish that hide in the wreckage. Eventually, the largest animals are attracted to the rich life on the shipwreck.
Shipwrecks give us valuable information about how sea plants and animals develop. We know exactly how long this wreck has been under water and how long sea life has been growing on it. Yet even the strongest steel shipwreck will finally be destroyed by the flows of water. But long after this wreck has been broken apart, it will still act as a reef (礁石). Layer upon layer of sea life has formed a structure that is now more natural than artificial, and will remain an island of life under the sea.
小题1:Which of the following is NOT TRUE about shipwrecks?
A.Most ships in ancient times sank easily and become shipwrecks. |
B.Shipwrecks, for scientists, are worth researching to get valuable information. |
C.The skeletons of old wooden shipwrecks will exist for quite a long time. |
D.Some sea animals tend to seek food on the shipwrecks. |
A.the differences between the ancient vessels and the modern ones |
B.how the ships become shipwrecks at sea |
C.how coral polyps live on the wreck in warm waters |
D.the value of studying shipwrecks at the bottom of the sea |
A.a hard outer covering | B.the skin of a rock |
C.a hole in a ship | D.a small house |
A.They will be pulled out of the sea for research. |
B.They are likely to disappear and form reefs. |
C.They will become an island under the sea. |
D.They will be like works of art. |
I was nurse on duty that day. I didn’t think there would be any patients, sighing about having to work on Christmas. Just then five bodies showed up at my desk, a pale woman and four small children.
“Are you all sick?” I asked suspiciously.
“Yes,” she said weakly and lowered her head.
But when it came to descriptions of their presenting problems, things got a little vague. Two of the children had headaches, but the headaches weren’t accompanied by the normal body language of holding the head or trying to keep it still. Two children had earaches, but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to produce it.
Something was wrong, but I didn’t say anything but explained that it might be a little while before a doctor saw her. She responded, “Take your time; it’s warm here.”
On a hunch (出于直觉), I checked the chart after the admitting clerk had finished registering the family. No address---they were homeless. The waiting room was warm.
I looked out at the family huddled by the Christmas tree. The little one was pointing at the television and exclaiming something to her mother. The oldest one was looking at an ornament on the Christmas tree.
I went back to the nurses’ station and mentioned we had a homeless family in the waiting room. The nurses, grumbling about working Christmas, turned to compassion for a family just trying to get warm on Christmas. The team went into action, much as we do when there’s a medical emergency. But this one was a Christmas emergency.
We were all offered a free meal in the hospital cafeteria on Christmas Day, so we claimed that meal and prepared a banquet for our Christmas guests. We needed presents. We put together oranges and apples in a basket. We collected from different departments candies, crayons and other things available that could be presents. As seriously as we met the physical needs of the patients that came to us that day, our team worked to meet the needs, and exceed the expectations, of a family who just wanted to be warm on Christmas Day.
Later, as the family walked to the door to leave, the four year old came running back, gave me a hug and whispered, “Thanks for being our angels today.”
小题1:Which of the following would be the best title of the passage?
A.Working Christmas Day | B.Christmas Day is Coming |
C.A Happy Family | D.A Pale Woman and Four Small Children |
A.Hardworking and outgoing | B.Serious and careful |
C.Hardworking and warmhearted | D.Serious and stubborn |
A.Something was wrong with one of the children’s heads. |
B.The pale woman forgot to write the address. |
C.The author did not understand the truth. |
D.The children’s mother told a lie. |
A.The author didn’t think there would be any patients on Christmas Day |
B.The woman was uncomfortable when she lowered her head |
C.The family appeared in the emergency room on Christmas Eve |
D.The woman and four small children were satisfied and grateful |
Ten years ago, no one thought that using computers could become compulsive(强迫性的)behavior that could affect the social and physical life of computer users. This obsessive behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.
They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at schools. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.
They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual(虚拟的)life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.
Because of the change in their behavior, they begin to isolate(孤立 themselves from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect the whole world.

Fingerprints are classified in the ways: by general shapes and contours(轮廓), by the finger positions of the pattern-types, and by size (often measured by counting the ridges in the loops). Every set of fingerprints has different “ridge characteristics” (i. e. the print of each separate finger is different from that of all the other fingers), which belong to one of four basic groups: arches, loops, whorls and composites. All fingerprints can then be divided into 1, 024 groups. By using details in the patterns above, these 1, 024 groups can be further divided into thousands of smaller groups, thus making it possible to find a particular set of fingerprints in a few minutes.
小题1:According to this passage, the true statement about human fingerprints is that ____.
A.people"s fingerprints sometimes can be passed on from parents to children |
B.people’s fingerprints are unique but identical twins may have the same fingerprints |
C.using fingerprints is the only way to identify people |
D.people"s fingerprints will not change in all their lives |
A.we can never find the same set of fingerprints among human beings |
B.finger impressions can be taken easily and quickly |
C.fingerprints offer a most useful and foolproof way of identifying people |
D.all of the above |
A.that is permanent | B.that is acceptable |
C.that can not go wrong | D.that is not foolish |
A.Fingerprints can be classified in three ways |
B.All fingerprints can be divided into 1, 024 groups and can not be divided further |
C.It is not easy to find a particular set of fingerprints in a short time |
D.People can not classify the fingerprints in an effective way |
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it had ever been in the past.“We were surprised by just how positive(肯定的) today’s young people seem to be about their families,” said one number of the research team.“They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds:they want a car and material goods,and they worry about whether school is serving them well. There’s more negotiation(商议) and discussion between parents and children,and children expect to take part in the family decision-making process. They don’t want to rock the boat(捣乱).”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel Lazall. “I always tell them when I‘m going out clubbing. As long as they know what I’m doing, they’re fine with me.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments(评论),“Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over. ”

B.is common nowadays |
