Ⅴ. 阅读理解
Is your mind on fire You might feel burned out(筋疲力尽的) after solving a difficult maths problem or studying for a whole day. Are our brains really “burning” when we spend a lot of time thinking In fact, our brains never stop burning calories(卡路里), even if we aren’t thinking about anything.
Our brains are powered by glucose(葡萄糖), a kind of sugar that can be found in carbohydrate(碳水化合物) like rice and noodles. The glucose goes to the brain through the bloodstream(血流). It powers the neurons(神经元) in our brains. Since our brain never really rests, it is burning energy in the form of glucose all the time. Even when we sleep, our brain needs energy to keep our body’s basic functions working. These include breathing, digesting and keeping the body warm.
The brain uses up 20 to 25 percent of the body’s total energy(总热量). That’s 350 calories per day for women and 450 for men. When you are five or six years old, your brain uses up to 60 percent of the body’s energy according to Live Science.
When we are thinking hard, the brain burns more calories. In one experiment, researchers found that people who were working on a hard task(任务) on a computer ate around 200 more calories than those who were resting. That explains why you feel hungry and eat more after taking an exam or studying for a long time.
(　　)33. Our brains get energy from 　　　　.
A. glucose B. calories
C. neurons D. resting
(　　)34. How many calories does an average man burn in a day
A. Around 20 to 35.
B. Around 350 to 450.
C. Around 580 to 750.
D. Around 1,800 to 2,250.
(　　)35. In the experiment, researchers found that 　　　　.
A. people burned fewer calories if they were thinking
B. people working on the computers ate more than others
C. people who were resting got hungry more easily
D. people working on hard tasks burned more calories
(　　)36. The passage mainly explains 　　　　.
A. why people feel hungry
B. how brains burn calories
C. when our brains work
D. why some people eat more
Ⅵ. 阅读短文,根据短文内容回答问题
　　What should we do if one of our classmates suddenly falls ill or gets hurt Here are some ways you should follow:
Broken bones
Take away clothing from the wound(伤口). Use an ice bag. Don’t move the hurt body part while waiting for the doctor to arrive.
Fainting(昏厥)
Have him or her lie with feet lifted a little. Don’t move the body. Make sure he or she can breathe and let in fresh air. Clean the person’s face with a cool cloth.
Animal bites(咬伤)
Wash the bite area with soap and water. Pack the wound with a clean cloth if it is bleeding. If the bleeding has stopped, cover the area with a bandage and take the person to the hospital. Make sure you remember what kind of animal it is, so the doctor can find the right way to treat(治疗) him or her at once.
Nosebleeds
Have the person sit up with his or her head tilted(倾斜) forward a little. Do not have the person tilt his or her head back because this may cause heavy breathing or coughing. Pinch(捏) the lower part of the nose for at least 10 minutes.
If you follow these ways, you can help your classmates a lot more.
