Passage 1
Once a peasant lost his horse and he went to town to buy another. Among the horses on sale he saw his own horse. “This horse is mine,” he said to the man standing by the horse. “Someone stole it from me three days ago.”
“How can that be?” the man said. “It has been mine for three years.”
“Three years?” said the peasant. “Are you sure?” Then he quickly covered both eyes of the horse with his hands and asked: “Which eye is he blind in?”“The left eye,” said the ma n. The peasant uncovered the horse’s left eye and people saw it was clear and shining. “Oh, I made a mistake,”said the man. “I meant to say the right eye.”“It’s not blind in either eye,”said the peasant, uncovering the other eye.

Passage 2
A heat pump is a single electric system that both heats and cools. In summer, a heat pump is a conventional air conditioner which removes heat from a building. In winter, the system reverses itself to use the natural heat that is always present in outdoor air. By taking advantage of the free heat, a heat pump is more economical to operate in winter than a system using electric resistance heat. Electric resistance heat
uses electricity as a raw material to create heat where no heat existed before. Heat pump, on the other hand, uses electricity to
move existing heat from where it already exists naturally (outdoors) to where it is wanted (indoors).
Heat energy will naturally flow from areas of greater concentration to areas of lesser concentration. That is what happens when hot food grows cool. The heat from the food flows into the air in the room until the food stabilizes at room temperature. Blowing air over substance will speed up the process, which is why a winter day will seem cold when there is a strong wind than when the air is still.
A heat pump uses this heat transfer process to move heat which is always in the air. The outdoor coil is made colder than the outdoors air. A fan blows outdoor air across the coil where heat is absorbed by the refrigerant. The refrigerant is then compressed and moved to the indoor coil and the heat is distributed in the building.
During the summer, a heat pump reverses this process. The indoor coil is made cooler than the indoor air, and so room heat flows into the refrigerant which is compressed and moved to the outdoor coil. The outdoor coil, which is hotter than the outdoor air, will lose heat energy.
6．A heat pump is used_____.
A. to cook
B. to heat
C. to cool
D. to heat and cool

A. electric resistance
B. natural heat and cool
C. coal energy
D. petrol energy
9. According to the passage, a heat pump is _____.
A. only used at night
B. only used in summer
C. only used in winter
D. used in summer and in winter as well
10. According to the passage, we can make the substance cool quickly by _____.
A. blowing cold air over it
B. putting it in the room
C. covering it with something
D. blowing hot air over it
VI. Short answer questions. (10 points)
Directions: in this part is a short passage with five questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statement in the fewest possible words (not exceeding 10 words).
The key to weight loss is regular physical activity. And surprisingly, you don’t have to give up eating or make the gym your second home to see long-term, positive effects.
Your body needs a certain amount of energy to maintain basic functions such as
breathing, blood circulation and digestion. The energy required to keep your organs functioning is referred to as the
resting or basal metabolic rate.
Any time you are active, additional energy is required. It is obtained from glycogen (肝糖) （carbohydrates）and fat stored in the blood, liver, and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.
Which of the two energy sources you use depends on the intensity and duration of your activity. The higher the intensity, the more your body will pull from the stored carbohydrates. The lower the intensity, the more your body will rely on fat as its fuel.
Aerobic exercise (any activity that increases oxygen intake and heart rate) is most effective for weight loss. When you perform aerobic activities you repeatedly contract large muscle groups such as your legs and arms. Walking, running, rollerblading, swimming, dancing, and jumping jacks are all forms of aerobic activity.
Surprisingly, if your aerobic activity is low to moderately intense and of long duration, you will burn more fat than if you had participated in a short burst of high-intensity exercise. In short, a brisk 30-minute walk will burn fat while a 100-yard sprint (疾跑) will burn glycogen.
Q1.What are regarded as basic functions of a human body?
Q2. Where can additional energy be obtained?
Q3. Which energy do you use when you train duration of your activity?
Q4. What is aerobic exercise?
Q5. Why is aerobic exercise thought of as the most effective weight loss?
