The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate（碳水化合物）, protein（蛋白质） and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein C= carbohydrate F=fat)

根据短文内容，判断下列句子是否正确，对的涂（A），错的涂（B）。

Cats are the most popular pets among Americans. So it is not surprising there are many expressions about cats. Do you know any of them? Now let me introduce some to you.
Some cats like to catch small birds, like canaries. If someone looks very proud or satisfied with himself, we say he looks like the cat that ate the canary.
Sometimes, a cat likes to play with a small animal it catches. So if you play cat and mouse with someone, you change between different kinds of behavior when dealing with another person. For example, a child might offer something sweet to her little brother, and then take it away when reaches for it.
A cat will often catch a small animal and present it to its owner. The saying “that looks like something the cat dragged in (把…拖进来)” describes something in bad condition.
A fat cat is a person with a lot of money.
There are many other expressions about cats in America. How interesting! Which kind of cat are you, or which kind would you like to be?
小题1:Americans don’t like cats as pets very much.
小题2:The canary is a kind of bird.
小题3:If you have much money, we can call you a sad cat.
小题4:We can say he looks like the cat that ate the canary if someone is very pleased with himself.
小题5:The passage introduces us four expressions about cats.

We expect that this will be the most popular of the four sports. So students should sign up (报名) as soon as possible. Students will take a private bus to and from Kwun Tong Sports Park. Each student will have to pay $ 10 each time for the cost of the bus. There will be four basketball courts available for our use with one teacher watching over each game.

Sports 4: Swimming
The Kowloon City Swimming Centre is a 10-minute walk from our school. Four teachers will go to the pool and watch the students from the poolside. We will only be able to use the pool for one hour (2: 45 p.m. to 3:45 p.m.). Only students skillful at swimming can take up this activity. The pool will have two lifeguards on watch.
