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.

Sports 1: Basketball
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 2: Gym
We will use St. Peter’s Park. There are two reasons for choosing this park. First, it is not very busy and crowded before 6:00 p.m. Second, it has lots of trees with plenty of shade. Students must bring along two bottles of water to prevent from being thirsty. All the activities here are free. And there will be a teacher on duty for each activity.

Hiking (远足)will be at Kowloon Peak. The activity will start at 2:30 p.m. and finish 90 minutes later. There will be 15 students in each group. And three teachers will be with the students. This sport will cost $ 75 per hour. Students should take plenty of water and sunglasses.
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. Girls must wear swimming suits. The cost is $ 15 per visit.
