Question

閱讀短文，從所給的選項中選出每段最恰當?shù)闹黝}句，并將其字母序號填在橫線上(其中有一項多余選項)。

A. Feed your head

B. Eat what you like

C. Learn what you love

D. Get to bed and go to sleep

E. Body exercise is brain exercise

F. Learn the power of risk taking

How would you like to learn more without having to study more? Here’s how:

1._____________. Your performance, attention, and the ability to concentrate(集中) are damaged by shortness of sleep. Teenagers need nine to ten hours of sleep a night for best performance(表現(xiàn)).

2.______________. The brain(大腦) runs badly if it doesn’t get enough fuel(燃料). That means protein(蛋白質(zhì)) and complex carbs (復合碳水化合物)-eggs and wheat bread for breakfast, say, rather than sugary cereal(含糖的麥片粥) and orange juice. The biggest mistake teens make is not to have breakfast or to go for sugar, which raises blood sugar levels.

3.______________. Body exercise really improves brain performance, perhaps because it increases blood flow, or perhaps because it makes stress and anxiety(焦慮) smaller. Twenty minutes of activity a day that raises your heart rate will do great good.

Learn now what you want to remember for the rest of your life. Teenage brains are much better at remembering things than the brains of young children or adults(成年人). Scientists aren’t sure why. Whatever the reason, the teenage years are the time to learn new languages and master(掌握) other lifelong skills.

4._____________. Adults are always worried about the downside(下降) of teenage risk(冒險) taking, and it’s true that teenagers are more likely than adults to get themselves in trouble by drinking and driving. But the fact that the parts of the brain that drive people to try new, risky, and exciting things appear to be more developed in teenagers can be a huge advantage. Pick certain challenges-difficult sports, a hard job, mastering a performance art, traveling overseas-and the teenage brain is able to deal with them. They have this power they’re given to go out and do it without fear.

5.______________. Because emotional(情感的) systems develop fast in teenager brains, teenagers learn things they’re interested in quickly and well. Their brains give them tools like attention on the project.
