Since the gene , called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging ,immunity and resistance in humans the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits such as immunity,”said Robin May , who led the study.
Populations across the world are aging at a surprising pace , bring potentially big challenges for health and social care systems . A study by Danish scientists last year found that half of babies born in rich world today will live to celebrate their 100th birthday . Scientists are eager to find out how people age to try to develop drugs to help them stay healthier lives extend.
“What we have found is that things like resistance and aging tend go hand in hang “ May said in an interview
May’s team compared longevity ,stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAV-16 in each of the four species and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes , which scientists believe play a role in the aging process. “The fact that subtle differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and many explain how differences in lifespan and related traits have arisen during evolution，”May saidIn which section may the text appear in a newspaper?
A Education B Science C Entertainment D Culture According to May ,
A resistance has a lot of to do with aging B FOXO genes can be found in worms
C genes play the same role in difference species D new drugs will change the genes in older peopleFrom the text we know that DAF-16
A is a gene that is only found in worms B can make people live longer
C has an effect on aging and immunity D has been quite familiar to scientists
Last summer I went through a training program and became a literacy volunteer (扫盲志愿者). The training I received, though excellent, didn't tell me how it was to work with a real student, however. When I began to discover what other people’s lives were like because they could not read, I realized the true importance of reading.
My first student Marie was a 44-year-old single mother of three children. In the first lesson, I found out she walked two miles to the nearest supermarket twice a week because she didn't know which bus to take. When I told her I would get her a bus schedule, she told me it would not help because she couldn't read it. She said she also had difficulty once she got to the supermarket because she couldn't always remember what she needed. Also, she could only recognize items by sight, so if the product had a different label, she would not recognize it as the product she wanted.
As we worked together, learning how to read built Marie’s self-confidence. She began to make rapid progress and was even able to take the bus to the supermarket. After this successful trip, she reported how self-confident she felt. At the end of the program, she began helping her youngest son, Tony, a shy first grader, with his reading. I found that helping Marie to build her self-confidence was more rewarding than anything I had ever done before.
As a literacy volunteer, I learned a great deal about teaching and helping others. In fact, I may have learned more from the experience than Marie did.What did the writer do last summer?
| A．She worked in the supermarket. |
| B．She helped someone to learn to read. |
| C．She helped some single mothers. |

| A．Because she liked to walk to the supermarket. |
| B．Because she didn't have a bus schedule. |
| C．Because she couldn't afford the bus ticket. |
| D．Because she couldn't find the right bus. |
How did Marie use to find the goods she wanted in the supermarket?
| A．She knew where the goods were in the supermarket. |
| B．She asked others to take her to the right place. |
| C．She managed to find the goods by their looks. |
| D．She remembered the names of the goods. |
Which of the statements is TRUE about Marie?
| A．She could do many things she had not been able to before. |
| B．She was able to read stories with the help of her son. |
| C．She decided to continue her studies in school. |
| D．She helped to build up my self-confidence. |
Traditional surgical procedures require surgeons to make large incisions(伤口) in a patient’s body in order to gain access to the internal organs. It was once common for heart surgeons, who perform highly specialized and complex procedures, to make long incisions in a patient’s chest and then split the breastbone to reach the heart. Patients who undergo surgery are often at the risk of infection, as bacteria can infect the cut in the skin. In addition, there is often a lengthy recovery period.
A surgical technique known as “keyhole surgery” has become more common in recent years. In general, the surgeon will make a couple of small incisions around the area where the operation is going to be performed. Tubes are pushed into the holes, and a tiny camera, which is called an endoscope, is put into the body. The camera is attached to a large monitor screen that is positioned so that the doctor can see it while he performs the operation. In addition to the camera, doctors also push their tiny surgical instruments through the tubes. The awkward part of keyhole surgery is that it is counterintuitive; that is to say, if a surgeon wants to move the tool to the left, he or she must push it to the right.
Other advancements in technology are also being used today in the OR (operation room). A new machine called the “da Vinci Surgical System” has been tested in hospitals in the U.S.. Unlike keyhole surgery, the da Vinci’s robot’s moving parts are designed to imitate the natural hand and wrist movement of a surgeon, thus providing better control and sensitivity. The system is controlled by a surgeon from a console(控制台). Sitting at a console a few feet from the patient, the surgeon can perform an operation by holding and moving highly sensitive pads that enable him or her to control the instruments. The area of the body on which the surgeon is working is enlarged on a screen, which is attached to the console. This gives surgeons a realistic three-dimensional view of the area — similar to what they would see during a traditional surgical procedure.
Although the da Vinci Surgical System is undergoing some trials for some procedures, it has been welcomed as revolutionary by many surgeons. Patients with serious illnesses must still undergo major surgery, but the smaller incisions and less invasive procedures typically mean that a shorter recovery time is needed. In some cases, the patient’s stay in the hospital has been cut in half when the da Vinci Surgical System was used. On the downside, some operations have taken up to fifty minutes longer because surgeons are inexperienced at using the new technology. As surgeons become more familiar with the machines, the time needed for surgical procedures is likely to decrease.What can be learned about the traditional surgery according to the passage?
| A．The cost of the traditional surgery is very high. |
| B．It often leaves a large wound in a person’s body. |

The two-week vacation at the end of summer school ended yesterday. Kevin had gone nowhere during his vacation. He had the money, but he hated to travel alone. He used to take vacations with Gary, his youngest brother, but they had a big argument at the end of their last vacation. Each of them had spent the last three years waiting for the other to apologize.
Kevin did not feel good about being on non-speaking terms with his favorite brother. But he was not going to ask for forgiveness when, in his mind, this whole misunderstanding was his brother’s fault.
So Kevin’s summer vacation was spent in his own “back yard.” As usual, he had planned to clean up his apartment. As usual, two weeks later his apartment looked just as it had two weeks before.
He did do one thing new and different during his vacation. There was a new coffee shop on Foothill Street. It served 25 varieties of delicious coffee at reasonable prices, and the staff was genuinely friendly. The shop was air-conditioned at a slightly chilly temperature. About eight small round tables were inside. Outside were four bigger tables. Each had four white metal chairs around it, and several big umbrellas provided shade. Even on hot afternoons, there was usually a pleasant breeze.
Kevin visited the coffee shop four times during his vacation. He always sat at a table outside by himself and read the free daily paper. Each day he was there, he read most of the newspaper articles while he enjoyed two cups of coffee.
Between articles, he took breaks by watching the nearby traffic and pedestrians. The coffee shop was next to a huge parking lot. The lot was for customers of a grocery store, movie rental store, pharmacy, bank, and restaurant. Kevin considered his outdoor seat the perfect place for one of his favorite activities—people watching.
The coffee shop, with its excellent location and coffee, had helped make his vacation a pleasant one. But he knew in his heart, had his brother been there to join him just one day, his vacation would have been a perfect one. Why didn’t Kevin go anywhere during his vacation？
| A．Because he was short of money. | B．Because he didn’t like traveling. |
| C．Because he had no company. | D．Because he had to clean up his apartment. |
What did Kevin do in his vacation?
| A．He cleaned up his apartment. | B．He had a big argument with Gary. |
| C．He worked in a parking lot. | D．He stayed at home most of the time. |
Which of the following is NOT mentioned about the coffee house?
| A．It served delicious coffee of different flavors. |
| B．It had an effective air-conditioning system. |
| C．It was often crowded with local customers. |
| D．It provided free newspapers for customers. |
Employment practices often reflect the needs of employers several decades ago．Times have changed．And so too has the Canadian workforce．Yet many employment practices have not kept pace with this change．For example, some work environments and washrooms designed for able-bodied workers seldom accommodate people who use a wheelchair．
Modernizing these practices is what employment equality is about．For example, making sure work benches and washrooms are adapted for disabled people entering the workplace paves the way for workers who become disabled on the job．By doing so, any given group of people? formerly discriminated against-now has access to better employment opportunities．
The objective, of course, is to make the workplace reflect Canadian society．However, this does not necessarily mean setting and enforcing quotas(实行配额）. Rather, it means identifying the barriers to employment and designing measures, with achievable goals and clear timetables, to remove them．
For example, according to the Canadian Union of Public Employees-Canada’s largest union, it would be unrealistic in the short term to insist that because half of the working age population is women, that half of the employees of an engineering firm should be women．At this moment, there would not be enough qualified female engineers．
A reasonable numerical goal would be based on the number of women who actually are engineers （8% ） and those who are studying to become engineers （25% ）．A short term goal of 13% would be appropriate without running the risk of hiring unqualified people．
Equally important is to ensure people who have been disadvantaged the chance to become qualified for new opportunities．If aboriginal people （土著居民） , for example, can’t qualify for certain jobs because they haven’t had access to appropriate educational opportunities, then an employment equality program would have to address that problem with training programs.
Employment laws in this country cannot be considered displeasing if they guarantee all Canadians fair and equal access to the workforce.The passage is mainly about how to ____.
| A．modernize equipment for the disabled at work |
| B．achieve equality of employment opportunities |
| C．protect women’s rights in employment |
| D．complete a job training program |
The underlined word "them" in Paragraph 3 refers to ____.
| A．barriers | B．measures | C．goals | D．timetables |
The example of women shows that ____.
| A．only a small percentage of women engineers will get promoted |
| B．13% of the working age women should be hired as engineers |
| C．policy makers should adopt a practical and flexible approach |
| D．the quota of women for employment should be raised |
The underlined word "address" in Paragraph 6 probably means _
| A．put forward | B．run into | C．find out | D．deal with |
