Whales live in the ocean, but they are not fish. They are warm-blooded mammals and must have air to breathe. The babies are born alive and drink milk from the mother's body. It took millions of years for the whale to develop as it is today.
Every spring groups of whales swim hundreds of kilometers to warm places to bear their young. Each group goes to the same place every year. The mothers take very good care of their babies. The fully grown whales are very gentle and playful with each other, and with humans. They “talk” to each other with a high noise that sounds beautiful. This“talking” can be heard for more than 300 kilometers in open waters.
Yet humans kill over a hundred whales a day. They kill them to make whale oils and a lot of other things. Killing them is a modern business with modern machines and even harpoons( 鱼叉炮) that explode( 爆炸) inside the whales. A whale dies very slowly and in great pain. Some ships kill every whale they can find, even the mothers and babies. Then there are no young whales to grow up or to bear more young.A commonly mistaken belief is that ____.

Each child has his individual（个人的）pattern of social, as well as physical, development. Some of it depends on his home life and his relationships with the people who love him. Children in large families learn how to get along with others through normal brother- sister play and tussles （打斗）. An only child, on the other hand , may have to learn his lessons in social living through hard experiences on the playground or in the classroom. Twins who always have one another to lean on may be slow in responding to others because they do not need anyone else.
A child who is constantly scolded and made to feel he does everything wrong may have a difficult time developing socially. He may be so afraid of displeasing the adults around him that he keeps to himself （where he can’t get into trouble）or he may take the opposite route and go out of his way to create trouble. Like the deserted child, he too may return to infantile （幼稚的）pleasures, developing habits that will satisfy him, but create barriers（障碍）toward social contact.Which of the following may have effect on children’s paten of social development?
| A．Age. | B．Education | C．Home life. | D．Gender（性别） |
The passage implies that which of the following may have the earliest time learning to get along with others?

| A．Too much scolding of children may make their social development difficult. |
| B．All children developed in the same ways. |
| C．Children who are constantly scolded may learn to get along with others quickly. |

-What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live, Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.According to the passage, human death is now mainly caused by __________.
| A．diseases and aging |
| B．accidents and war |
| C．accidents and aging |
| D．heart disease and war |
In the author’s opinion, today’s most important advance in technology lies in __________.
| A．brain cell | B．the Internet |
| C．medicine | D．human organ |
Humans may live longer in the future because _________.
| A．heart disease will be far away from us |
| B．human brains can decide the final death |
| C．the basic materials of cells will last forever |
| D．human organs can be repaired by new medicine |
How long can humans live in the future according to the passage?
| A．Over 100 years. |
| B．More than 120 years. |
| C．About 150 years. |
| D．The passage doesn't tell us. |
-American office workers spend an average of 52 hours a week at their desks, according to a statistic survey. Some might argue that not all that time is spent working，but still all those hours in windowless offices with artificial light can have an influence.
A few green additions could have a large effect on worker happiness，according to the survey led by Tina Cade from Texas State University.
“We pretty much found out that if you had windows and plants or even if you just had plants in your office, you were more satisfied with your job,” Cade told LiveScience. “We thought it was important for offices because a lot of times people are looking for ways to keep employees happy and do all these expensive things like building a gym. Maybe for less investment they could put in a few plants in important places.”
The team surveyed 450 office workers in Texas and the Midwest，asking questions about job satisfaction and the work environments. When asked about their overall life quality,82 said they felt “content” or “very happy”. Only 69 percent of those who work with plants but without windows，and 60 percent of those who have windows but no plants, said they felt this way.
The group of people who work without plants or windows were the most dissatisfied，with only 58 percent of them saying that overall they were “content” or “very happy”. While no one who works with plants，windows，or both reported they felt “miserable”, 0.8 percent of those who work in offices without either said they were “miserable”. “I was really surprised that having a plant in your office appeared to be more beneficial than having a window in your office,” Cade said. “Everybody says, ‘I need a window!’ but actually it seemed like a plant could be a suitable alternative.”What does the passage mainly tell us?
| A．Green plants can increase job satisfaction. |
| B．An easier way to increase job satisfaction. |
| C．What the best working environment is. |
| D．Who are happy with their job environment. |
Among the 450 people surveyed, ________.

Which of the following statement is true?
| A．The employers want to do little to keep employees happy. |

-Without proper planning, tourism can cause problems．For example, too many tourists can crowd public places that are also enjoyed by the inhabitants(居民) of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people of a destination(目的地) country and how tourism affects them. Tourism should help a country, keep the customs and beauty that attract tourists．Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
On the other hand, if there is not enough tourism，people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports，air terminals, first－class roads, and other support facilities（设施）needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.
Building a hotel is just a beginning．There must be many support facilities as well，including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.Which of the following has most probably been discussed in the part that goes before this passage?
| A．It is very important to develop tourism. |
| B．Building roads and hotels is necessary. |
| C．Support facilities are highly important. |
| D．Planning is very important to tourism. |
Too much tourism can cause all these problems EXCEPT ________.
| A．a bad effect on other industries |
| B．a change of tourists’ customs |
| C．over－crowdedness of places of interest |
| D．pressure on traffic |
Not enough tourism can lead to ________.
| A．an increase of unemployment (失业) |
| B．a decrease (减退) in tourist attractions. |
| C．the higher cost of support facilities |
| D．a rise in price and a fall in pay. |
The underlined word “handle” in the last paragraph most probably means _________.
| A．get in |
| B．pick up |
| C．carry away |
| D．take down |
