H5N1 avian influenza, commonly known as bird flu (流感), has killed at least 15 people across Asia and was proved in China on January 27. No human cases have been found in the main??land, but 13 of the country’s 31 provinces have reported the disease in poultry.

The Chinese government has taken measures to prevent and control the disease. Poultry within 3 km of infected (受感染的) farms is to be killed and those within 5 km vaccinated (接种疫苗). At the same time, there will be continuous monitoring and daily reports on the disease across the country, and in??creased production of bird flu vaccines.

Among the 11 Asian countries and regions having bird flu in animals, only Vietnam and Thailand have reported human cases. The people infected were reported to have caught the disease from poultry.

While the World Health Organization ( WHO) says there is “no proof (证据) of human-to-human infection (传染)” of bird flu, the big fear is that the disease could combine with a human flu virus (病毒) to produce a deadly new disease that will kill millions of people across the world. Many Asian farmers live closely with their animals and sell live chickens in the market. This greatly increases the chance of humans being infected with bird flu.

A spokesman of the WHO said that Asian countries having bird flu should introduce a more healthy way of raising and selling chickens. The people there have to completely change their way of life and manners towards animals. Here are some safety measures for people to stay healthy;

*   Keep fit through usual exercise;

*   Avoid infected poultry and infected people;

*   Avoid eating uncooked or under-done poultry and eggs;

*   Make sure there is always fresh air in your home;

*   Cover your mouth and nose when coughing or sneezing;

*   Wash your hands as often as possible.

What does the underlined word “poultry” mean?

A. Wild birds.

B. Wild animals.

C. Home-raised birds.

D. Home-raised animals.

From the passage, we learn that __________.

A. infected poultry within 3 km was killed in China

B. the first bird flu case was proved in China on Jan. 27

C. human infected cases were found in 11 Asian countries

D. over two thirds of China have been affected by the bird flu

What do people fear most?

A. Poultry will infect many people.

B. There will be human-to-human infection.

C. The disease can spread quickly among people.

D. A new disease combining bird flu and a human flu will break out.

Once again, science supports what your grandmother told you: A good night's sleep helps your body fight a cold.

People who averaged fewer than seven hours of sleep per   1   in the weeks before being exposed to the cold virus were nearly three times   2   likely to get sick as those who   3   eight hours or more, a new study found.

Researchers used frequent telephone   4   to track the sleep   5   of more than 150 men and women aged 21 to 55 over the course of a few weeks. Then they   6   the subjects to the virus, quarantined them for five days and kept   7   of who got sick.

  8   sleeping more, sleeping better also seemed to   9   the body fight illness: Patients who fared better on a measure   10   as 'sleep efficiency' - the percentage of time in bed that you're actually sleeping - were also   11   likely to get sick.

The results held   12   even after researchers   13   for variables such as body-mass index, age, sex, smoking and pre-existing antibodies to the   14   .

  15   your grandmother, the researchers aren't exactly sure   16   sleeping better makes you less likely to   17   a cold. But they   18    take a stab at the answer: 'Sleep disturbance influences the regulation of proinflammatory cytokines（促炎细胞因子）, histamines, and other symptom mediators that are released in response to infection.'

The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health.
