Malaria, the world's most widespread parasitic（寄生虫引起的）disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't （or can't） seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect （感染）. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

Take control of your health by learning these four numbers. They’ll help with everything from losing weight to protecting your heart.

Your daily calorie needs

This is not technically a measurement, but it can have a huge influence on your health. Most women need 2,000 calories a day for good health, and men generally need about 2,550. One way to work out your daily calorie needs is to multiply (乘以) your weight in pounds by 13 to 15, depending on your activity level. But roughly, that’s 300 to 400 calories for breakfast, 500 to 600 for lunch, and 600 to 700 for dinner. Trying to lose weight? Eat about 500 calories less.

Your waist size

Waist size is one of the best ways to measure whether your weight is affecting your heart health. When body fat is packed into your abdomen (腹部),your risk of heart attack increases. For women, health risk begins to rise when your waist is more than 35 inches. For men, risk increases with a measurement when your waist is over 40 inches.

 Your blood pressure

Blood pressure rises and falls normally during the day. When it remains high, you have high blood pressure and this carries a higher risk or heart disease and stroke.

A reading of 140/90 mm Hg or more is considered high, and if it’s between 120/80 and 139/89, you may still be at risk and should be taking steps to prevent the development of high blood pressure.

Your morning pulse rate

Your pulse rate is the number of times your heart beats in one minute. A normal resting pulse rate is 60 to 90 beats per minute. People who are fit tend to have lower resting pulse rates because their heart muscles are in good shape. But if you don’t exercise regularly and your heart rate is lower than the normal range, tell your doctor—it could be a sign of heart disease.

71. How can you control daily calories if you decide to lose weight?

      A. Eating around 2,000—2, 500 calories

      B. Having fewer than 500 calories.

      C. Cutting down about 500 calories from amount.

      D. Taking in a little fewer calories than the total amount

72. When your waist size becomes larger than the figures given in the text, ________.

      A. you are surely unhealthy                     B. you should try to reduce your waist

      C. you should go on a strict diet              D. the chance of heart disease rises

73. What should you do if your blood pressure is 128/83 mm Hg?

      A. Take measures to stop it going high.           B. Leave it as it is as there was no risk.

      C. Measure the blood pressure regularly.  D. Go to see a doctor for advice.

74. Which of the following is true of a resting pulse rate?

      A. The slower it is, the healthier.           B. The more exercise you do, the slower it is.

     C. Don’t worry if it is lower than normal.   D. Regular exercise can make it slower.

75. What might be the best title of this text?

      A. Healthy living style              

B. The secrets of your body

      C. What are your body functions          

D. Healthy numbers you need to know

DID you get a flu shot this year? For the first time, the Centers for Disease Control and Prevention in the US is recommending that all children aged from 6 months to 18 years receive the flu vaccine．

Vaccines battle diseases caused by bacteria and viruses．A weakened form of the germ （微生物） is introduced into the body．The body makes special substances called antibodies to fight the germs．If the actual germs were to attack, the antibodies would fight it．

   Because there are many kinds of flu viruses, scientists must create a new vaccine  formula （方程式） each year．Researchers must make a prediction．

It is like forecasting the weather．Sometimes they are right on, and sometimes they are off．But even when the vaccine does not closely match circulating flu types, it can make the illness less serious．

   "The flu vaccine is not as effective as the polio （小儿麻痹症） vaccine or the measles vaccine," says Dr William Schaffner of Vanderbilt University School of Medicine．"It's not a great vaccine, but it is quite a good vaccine．"

But a flu vaccine doesn't work for everyone．There are certain people who should be careful about taking it．

Because the vaccine is produced in eggs, those who are allergic （过敏的） to eggs should not take it．If you have a fever, you should wait until you recover．

Some people are afraid that they might get the flu from the flu shot．Scientists say that it is not possible, because the viruses in the flu shot are inactivated．But some minor side effects such as low-grade fever and body ache could occur．If they do, they begin soon after the shot and usually last only one to two days．

Did you know?

Smallpox was the first disease people tried to prevent by putting a virus into a healthy person．In 1796, English scientist Edward Jenner placed some infected material under a boy's skin．

64．By saying "It's not a great vaccine, but  it  is  quite  a  good  vaccine",  the  author  means the flu vaccine               ． 

       A．does help to make illness less serious

       B．is not effective, compared with the polio and measles vaccines

       C．is not as effective as the polio and measles vaccines

       D．is quite good because it works for everyone

65．We can infer from the passage that               ．  

       A．those who are allergic to eggs should not take flu vaccine

       B．you should go to a doctor if you have a fever or body ache after taking the flu vaccine

C．all the flu vaccines are not effective for everyone

D．it is possible that some people might get the flu from the flu shot

66．It is not advisable for everyone to take flu vaccine because               ．  

       A．there are many kinds of virus

       B．the flu vaccine is not as effective as the polio and measles vaccines

       C．it has some minor side-effects

D．someone may be allergic to it

67．What topic will be discussed in the following paragraph?   

       A．How the smallpox vaccine worked on the boy．

       B．The side-effects of smallpox vaccine．

       C．The origin of the flu vaccine．

       D．What kind of people should be careful about taking smallpox vaccine．
