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 biotechnology. 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 to repair their organs. 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 ________.

More than 6000 children were expelled(开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8.
The department gave a report to the expulsions(开除) as saying handguns accounted for 58 percent of the 6093 expulsions in 1996---97, against 7 percent for rifles(步枪) or shotguns and 35 percent for other types of firearms.
“The report is a clear sign that our nation's public schools are cracking down(严惩) on students who bring guns to school,” Education Secretary Richard Riley said in a statement. “We need to be tough-minded about keeping guns out of our schools and do everything to keep our children safe.”
In March1997, an 11 years old boy and 13 years old boy using handguns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14-year-old boy killed three high school students and wounded five in Dasucah, Kentucky.
Most of the expulsions, 56 percent, were from high school, which have students from about age 13. 34 percent were from junior high schools and 9 percent were from elementary schools, the report said. The main idea of the passage is that in the US schools _______.
| A．students enjoy shooting |
| B．students are eager to be soldiers |
| C．safety is a problem |
| D．students can make guns |
From what Richard Riley said we can infer that ________.
A. the number of the expulsions is not large
B. the number of the expulsion is wrong
C there are soldiers hiding among the students
D. guns are out of control in US schools The main idea of paragraph four shows us ______.
| A．some examples of shoot in US schools. |
| B．the American's feeling. |
| C．some famous schools. |
| D．that some teachers were killed by students. |
From this passage we get to know that ________.
| A．every American cannot have guns |
| B．only soldiers and police can have guns |
| C．every American citizen can own guns |
| D．teachers have no money to buy guns |

One answer to the question of land shortage was suggested by an organization some years ago. A city was to be built at sea, housing 30,000 people.
The suggestion was to shape the city like a harbor(港口).The outer wall of the harbor would stand on steel columns resting on the sea-bed. Naturally this could only be where the water was fairly shallow. The people would like to live in flats in the fifty-metre high outer wall. The flats would be all face inwards, and would be made of concrete(混泥土) and glass. The glass would be specially made and colored to control the heat and strong light from the sun. The planners called this man-made harbor would be calm. On it would be floating islands carrying more building: a hospital, two theaters, museum, an art exhibition hall and a church. On one of the islands would be a special factory to take the salt out of sea water and turn it into fresh water.
People living in the city could move around on small boats driven by electricity, so there would be no air pollution from the burning of gas. There would be platforms outside the man wall for ships bringing supplies. People could also travel to the mainland by motorboat or water plane. What was suggested about the construction of a new city at sea?
| A．The city was to be designed together with a harbor. |
| B．The walls around the city would be made of steel and glass. |
| C．The building of the city would rest on a floating island. |
| D．The people would live in tall building surrounded by a wall. |
How would fresh water be supplied to the city?
| A．By treating sea water. |
| B．By getting it from the surrounding islands. |
| C．By building a small lake of fresh water inside the city. |
| D．By transporting it from the mainland. |
The suggestion made by the organization is to solve the problem that _______.
| A．there is not enough space for building cities on land |
| B．land transportation has became increasingly difficult |
| C．there are too many people on land |
| D．present cities are heavily polluted by cars |
The purpose of the writer is _______.
| A．to suggest how new type of harbor could be built at sea |
| B．to give a description of a new-type city |
| C．to draw people's attention to the problem of air pollution |
| D．to introduce a new way of building harbor-cities |
Mobile phones are an important business tool for farmers in rural areas．But they also put a valuable educational tool in their hands．
The University of Illinois in the United States has a project called SAWBO—Scientific Animations Without Borders．It produces educational videos that can be downloaded to cell phones．The goal is to help people in developing countries improve their lives．
One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops．The process starts with sorting and drying the neem fruits．Then let the fruit dry in the sun for about three or four days, until they become brown．Using a mortar（碾槌） and stick, the fruits are slightly pounded to remove the shells from the fruits without breaking the seed inside．
The videos use computer animation（动画）．Some of the animated characters are a little funny looking-like a farmer with a long nose．But the subjects are serious, including a health video on preventing cholera（霍乱）．Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood．He says, “The information is digested in such a way that in two minutes, we can transmit a complex idea．”
The researchers tested the seven-minute video on seven mobile phones．They wanted to see if people would share the video using Bluetooth wireless technology．With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the internet．As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages．" This is just incredible impact," said Francisco Seufferheld．
The team has made a few videos so far．These are available in a total of eighty languages, dialects and accents．Professor Barry Pittendrigh says there are plans for more videos later this year．What is the text mainly about?
| A．A best-selling mobile phone |
| B．A valuable educational project for farmers |
| C．United States support for developing countries |
| D．A new type of scientist –farmer relationship |
The SAWBO program is introduced in order to ____．
| A．raise farmers’ standard of living |
| B．do some research on mobile phones |
| C．develop farmers’ practical skills |
| D．help farmers prevent insect damage to crops |
The biggest advantage of the program is that it______．
| A．includes health video on preventing cholera |
| B．can be passed to farmers using Bluetooth technology |
| C．can be used to sort and dry the neem fruits |
| D．is easy for farmers to understand |
Which of the following words can best take the place of the word “ pound” in the 3rd paragraph?

Brrriiinnng．The alarm clock announces the start of another busy weekday in the morning．You jump out of bed, rush into the shower, into your clothes and out the door with hardly a moment to think．A stressful journey to work gets your blood pressure climbing．Once at the office, you glance through the newspaper with depressing stories or reports of disasters．In that sort of mood, who can get down to work, particularly some creative, original problem-solving work?
The way most of us spend our mornings is exactly opposite to the conditions that promote flexible, open-minded thinking．Imaginative ideas are most likely to come to us when we’re unfocused．If you are one of those energetic morning people, your most inventive time comes in the early evening when you are relaxed．Sleepy people’s lack of focus leads to an increase in creative problem solving．By not giving yourself time to tune into your wandering mind, you’re missing out on the surprising solutions it may offer．
The trip you take to work doesn’t help, either．The stress slows down the speed with which signals travel between neurons （神经细胞）, making inspirations less likely to occur．And while we all should read a lot about what’s going on in the world, it would not make you feel good for sure, so put that news website or newspaper aside until after the day’s work is done．
So what would our mornings look like if we wanted to start them with a full capacity for creative problem solving? We’d set the alarm a few minutes early and lie awake in bed, following our thoughts where they lead．We’d stand a little longer under the warm water of the shower, stopping thinking about tasks in favor of a few more minutes of relaxation．We’d take some deep breaths on our way to work, instead of complaining about heavy traffic．And once in the office—after we get a cup of coffee—we’d click on links not to the news of the day but to the funniest videos the web has to offer．What is the purpose of the first paragraph?
| A．To tell us a specific story． |
| B．To introduce the topic of the passage． |
| C．To indicate how busy one usually is in the morning． |
| D．To show mornings are not suitable for creative work． |
What does the author imply about newspapers?
| A．They are normally full of bad news． |
| B．They are solution providers． |
| C．They are a source of inspiration． |
| D．They are more educational than websites． |

| A．wander into the wild | B．listen to a beautiful tune |
| C．stop concentrating on anything | D．switch to the traffic channel |
