Your body prevents harmful microorganisms entering and causing harm. The
skin, for example, doesn't allow microorganisms to enter. Hairs and mucus in your nose catch invaders, and then you push themucus out when you cough, sneeze or blow your nose. Enzymes and acids in the body, and white blood cells also destroy bacteria.
Do antibiotics help ? Doctors use antibiotic drugs to fight bacterial infections, but antibiotics don't work
against viruses. This is why doctors don't give antibiotics to patients with a
common cold or flu.
How does immunization work ? Immunization
(or vaccination) is another way of protecting the body, by injecting the body with
dead or inactive microorganisms. After vaccination, the body starts to
make antibodies that destroy the microorganism. Because the microorganisms in the
vaccination are not dangerous, the person doesn't getill. When they come

into contact with a live (dangerous) micro organism, then the antibodies
destroy the infection before it makes them ill.

B. Everyone needs different amounts of energy per day depending on age, size and activity levels. An athlete needs more calories than an office worker. To stay in shape, an average adult requires at least 1,800 calories per day (according to the Food and Agriculture Organization of the United Nations). If we eat just the number of calories our body needs each day, we will probably be healthy. However, eating too much can make you put on weight. To lose weight, eat fewer calories than your body burns each day.

C. These are some experts' tips to reduce calorie intake. First, you must know how many calories you need each day and always count them in your diet. Have small frequent meals and drink more water too. This will help you feel less hungry. Furthermore, avoid all sugary drinks and junk food. They are high in energy but low in nutritional value.

What factor decides the amount of energy a person needs each day?

A. Age

B. Size

C. Activity levels

D. All are correct.

What do you often do after school? In my school, there are a lot of clubs which students can take part in after school hours.

The club that has the biggest number of members is the swimming club called “Blue Dolphins”. I myself love swimming so I am a member of this club. I go to the swimming pool twice a day and swim for about an hour. I’m really interested in swimming breaststroke because it helps me move as fast as I can. I’m also fond of backstroke. I swim backstroke when I want to relax, breathe and let my body float freely. It’s very relaxing.

The second club I would like to mention is the charity club. Its name is “Golden Heart”. Members of the club often do community service. This month, they are conducting a clean-up campaign to protect the environment around the school. They collect trash, clean the toilet area, and grow plants. I am not a Golden Heart’s member, but I participate in their activities whenever I can.

If you can sing, dance or play musical instruments, the musical club “Heartstrings” is definitely for you. The president of the club is Mike, my best friend. He is not only good-looking but also sings beautifully and plays the guitar very well.

In conclusion, we should do as many activities as possible in our free time to have good health and a fresh mind to prepare for lessons in class. Spending all our time studying is not a good idea.

Question. The writer is fond of backstroke when ________

A. he has a competition

B. he is hot

C. he is tired

D. he want to relax
