    LONDON (Reuters) — Children are dying for lack of drugs tailored to their needs, according to the World Health Organization (WHO), which launched a global campaign on Thursday to promote more research into child medicine.
    More than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters.
    The problem is even worse in developing countries where price remains a major barrier and 6 million children die each year from treatable conditions.
    In the case of HIV/AIDS, the few existing pediatric therapies（儿科的疗法）developed for children generally cost three times more than adult ones.
    As a result, clinicians lack clear guidelines on the best drug to use and often have to guess at the correct dose.
    Fortunately, the WHO has drawn up the first international List of Essential Medicines for Children, containing 206 products considered safe for children.
    “But a lot remains to be done. There are priority medicines that have not been adapted for children’s use or are not available when needed,” said Dr Hans, the U.N. agency’s director of medicines policy and standards.
    Medicines that need to be adapted to children’s needs include many antibiotics, pain drugs as well as combination pills for HIV/AIDS, tuberculosis and malaria.
    The agency is building an Internet entrance linking to clinical trials carried out in children and will launch a Web site with the information early next year.
    Testing medicines on children has always been a controversial issue, since good ethical（伦理的）practice requires informed agreement from people participating in clinical trials, which is difficult to obtain in the case of children.
    As a result, research-based drug companies have been wary of developing child-friendly medicines and general companies have been slow to produce them at lower cost.
    In an attempt to deal with the issue, both Europe and the United States now have special rules offering extended patent protection for drugs that have been tested on children.
    小题1:Which of the following is the best title of the passage?
    A．A Global Campaign to Promote Research into AIDS Medicine
    B．WHO Says Children are Dying for Lack of Child-sized Drugs
    C．Many People are Concerned about Children’s Drugs
    D．Measures Taken to Develop Child-friendly Medicine Quickly
    小题2:Which of the following medicine is not needed to be adapted to children’s need according to the passage?
    A．Pain killers.B．Tuberculosis.
    C．AID pills.D．Flu pills.
    小题3:Why has testing medicines on children always been a controversial issue?
    A．It is against good ethical practice
    B．Children shouldn’t take part in clinical trials.
    C．It is hard to get informed agreement from children tested.
    D．Parents don’t allow their children to be tested on medicine.
    小题4:The underlined word “wary” in the last but one paragraph means _________.
    A．fastB．fondC．cautiousD．uninterested
    小题5:What can be inferred from the passage?
    A．There is still a long way to go on children’s medicine.
    B．An Internet entrance is being built to link to clinical trials carried out in children.
    C．Both Europe and the United States now have special rules offering extended patent protection for children’s drugs.

    [1]A researcher who helped make crops grow in dry land areas received the World Food Prize last week. Daniel Hillel was recognized for his work in developing what is called “micro-irrigation" or “drip irrigation." It has made farming possible in places where there is little rainfall or water.
    [2]Daniel Hillel's farm near his home in Israel shows his ideas at work. “Each tree row is fed by these plastic tubes that drip water at the base of the tree." Watering plants drop by drop has changed agriculture by reducing the amount of water needed to grow crops.
    [3]Farmers now depend on drip irrigation in many areas, including vineyards in Spain, onion fields in Africa, and even farms in the United States. Farmers in California grow about fifty percent of the fruits and vegetables of the continental United States. And the reason that is possible is because of these drip and micro-irrigation techniques.
    [4]Daniel Hillel was born in California. After his father died, his mother moved the family to Palestine, where her parents lived. The area eventually became part of the state of Israel. Daniel Hillel got his start in dry land farming as a settler in Israel's Negev Desert in the 1950s. “The issue was efficient use of water because land is available and extensive while Water is limited."
    [5]Desert farmers were not able to push water through irrigation canals to their crops the way farmers have since ancient times. So Mr. Hillel and others gave plants just what they needed, just where they needed it. The idea was to apply the water little by little. The method worked so well that soon Mr. Hillel was traveling the world, showing others _____.
    小题1:Why did Daniel Hillel win the World Food Prize?   ( no more than15 words)
    _____________________________________________________________________
    小题2:How did drip irrigation change agriculture? ( no more than12 words)

    C
    Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
    If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(万亿)minutes annually - earn $109 billion for the wireless carriers.
    Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
    Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
    “Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
    Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid（易吸收的液体）. No studies have yet been completed on cell phone radiation and children, she says.
    Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
    Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen（腹部）.
    小题1:Why is the warning in the small print?
    A．They think people will not care about it.
    B．There is not enough space for the warning.
    C．They don’t want the users to pay attention to it.
    D．The warning is not important at all.
    小题2: What does the underlined word in sixth paragraph probably mean?
    A．acceptable B．valuableC．accessible D．easily affected
    小题3:What can we conclude from the last paragraph?
    A．Pregnant women should keep cell phones away.
    B．People should use cell phones in the correct way.
    C．If you are a child, you’d better text than make phone calls.
    D．When you use a cell phone, use a wired headset or the phone’s speaker.
    小题4: What does the passage mainly talk about?
    A．Be careful when using cell phones.
    B．Don’t hold your cell phone against your ear.
    C．Rats exposed to radiation have damaged DNA in their brains.
    D．Low-energy radiation could damage cells that could lead to cancer.

    TOKYO, Japan (AP) – Japan is very serious about robotics (机器人技术). If the androids are going to fit in, they probably need to learn the Japanese custom of serving tea. Fortunately, researchers at the University of Tokyo are exploring just that. In a show this week, an android（有人特点的）with camera eyes made by Kawada Industries Inc. poured tea from a bottle into a cup. Then another robot on wheels delivered the cup of tea in an experimental room that has sensors(感应器)embedded in the floor and sofa as well as cameras on the ceiling, to simulate（模仿）life with robot technology.
    “A human being may be faster, but you’d have to say ‘Thank you,’” said University of Tokyo professor Tomomasa Sato. “That’s the best part about a robot. You don’t have to feel bad about asking it to do things.”
    Sato believes Japan, a rapidly aging society where more than a fifth of the population is 65 or older, will lead the world in designing robots to care for the elderly, sick and bedridden（卧床不起的）. Already, monitoring technologies, such as sensors that automatically turn on lights when people enter a room, are becoming widespread in Japan.
    The walking, child–size Asimo from Honda Motor Co. greets people at showrooms. NEC Corp. has developed a smaller companion robot on wheels called Papero. A robot available since 2004 can entertain the elderly and others in need of companionship.
    Sato says his experimental room is raising awareness about privacy questions that may arise when electronic devices（设备）monitor a person’s movements down to the smallest detail.
    On the bright side, the tea – pouring humanoid has been programmed to do the dishes.
    小题1:What is the best title of this passage?
    A．“Thank You” Will Never Be Needed in Japan
    B．Monitoring Technologies Are Widespread in Japan
    C．Robot Is Designed to Care for the Elderly.
    D．Robot technologies are widespread in Japanese daily life.
    小题2:The underlined word “embedded” in the first paragraph probably means      .
    A．fixedB．establishedC．settledD．rooted
    小题3:According to Professor Sato,       .
    A．the robot serves tea much faster than a human being
    B．the robot does anything like human beings
    C．tea – serving robot helps to form laziness of the aging society
    D．tea – serving robot doesn’t need any reward for the service
    小题4:Which of the following statements is NOT true?
    A．A robot can imitate people to complete complicated tasks.
    B．A robot has been programmed to clean the dishes.
    C．All the problems in the aging society can be solved by robots.
    D．The number of aging people is increasing rapidly in Japan.
    小题5:We can infer from the passage that        .
    A．people are afraid of being monitored by robots.
    B．the technology of robots has been highlighted（强调） in Japan.
    C．robots can completely take the place of human beings.
    D．people’s privacy should be strictly protected

    Sydney—A shark savaged a schoolboy’s leg while he was surfing with his father at a beach in Sydney on February 23. It was the third shark attack along the coast of Australia’s largest city in a month.
    The 15­year­old boy and his father were in the water off Avalon, on Sydney’s northern beaches, around dawn when he was attacked. The city’s beaches are packed with locals and tourists during the summer months.
    “The father heard a scream and turned to see his son thrashing (激烈扭动) about in the water,” police said. “Fortunately, the shark swam away and the boy was helped to the shore by his father.”
    Lifesaving Club spokesman Nick Miller said, “It got him around the top of his left leg and the father came and dragged him out of water.” He said the boy was bleeding heavily when he was brought to the shore. “There was a lot of pain, as you can imagine.” The teenager was airlifted to hospital for treatment for leg injuries.
    Police said the bites “cut through to the bone”, but the boy did not appear to have sustained any fractures (骨折). He was in a stable condition now.
    Several beaches were closed after the attack. Water police and lifeguards were searching for the shark, while police hoped to identify its species by the shape of the bite marks. But they said it was too early to say what type of shark attacked the boy. “I don’t even know if he saw it,” Miller said.
    Many shark species live in the waters off Sydney’s beaches, but attacks on humans are still relatively rare. However, there were two attacks on successive days earlier this month, one on a navy diver in Sydney harbor，not far from the famous Opera House, and the other on a surfer at the city’s world­famous Bondi beach.
    Fishermen say shark numbers are on the rise. There is a ban on commercial fishing in the harbor, which has increased fish stocks. Marine experts also claim environmental protection has created a cleaner environment, attracting sharks closer to the shore as they chase fish. Many shark species, including the Great White—the man­eaters made famous in Steven Spielberg’s Jaws—are protected in Australian waters.
    小题1:The report mainly tells us________.
    A．shark attacks on humans are on the rise
    B．sharks attacked humans three times in one month
    C．a boy was attacked by a shark at a Sydney beach
    D．shark numbers are increasing in the waters off Sydney’s beaches
    小题2: The underlined word “savaged” in the first paragraph probably means “_____”.
    A．attractedB．draggedC．bitD．packed
    小题3: What do we know about the city of Sydney from the passage?
    A．It is one of the largest cities in Australia.
    B．Sydney harbor is not far from the famous Opera House.
    C．There are many locals and tourists on its coast all the year round.
    D．There are few shark species in the waters off Sydney’s beaches.
    小题4: About the injury of the boy we know that________.
    A．he was losing much blood when he was dragged out
    B．he was very nervous when he was sent to hospital
    C．he may be in danger of losing his leg
    D．he was injured in the right leg
    小题5: All the following are the causes of Australia’s sharks’ increasing except that___.
    A．environmental protection has created a cleaner environment
    B．a ban on commercial fishing has increased fish numbers
    C．many shark species are protected in Australian waters
    D．the film Jaws has made the Great White famous

    An Italian couple are to become the world's oldest divorcees, after the 99 - year – old husband found that his 96 - year - old wife had an affair（婚外情）in the 1940s．
    The Italian man, called by lawyers in the case as Antonio C, was looking through an old drawer when he made the discovery a few days before Christmas．    
    In spite of the time that had passed since the affair, he was so upset that he immediately asked his wife of 77years, named as Rosa C, whether it was true, and demanded a divorce．
