Sometimes, you do not finish drinking your glass of water before you go to bed. 1.

But have you ever wondered if it is still safe to drink?

“If you have clean water in a clean glass, you’re fine to drink it for a day or two,” Kellogg Schwab from the Johns Hopkins University Water Institute in the US told Time.

2. That’s because after about 12 hours, the carbon dioxide (二氧化碳) in the air reacts（反应）with the water in your glass, slightly lowering its pH level.

Also, there might be more microorganisms (微生物) in your water if you leave it out overnight. Microorganisms grow more quickly at room temperature. These microorganisms can stay on your glass. 3. But as long as you clean your glasses very often, this will not be a problem.

In countries like the US and UK, people often drink water directly from the tap (水龙头).4. Most experts say that tap water has a shelf life of six months, according to Zane Satterfield from West Virginia University, US. After six months, there is less chlorine (氯) in the water and bacteria (细菌) start to grow. You’d better not drink the water otherwise you may get sick.

5. Schwab said people should be careful with them. If you leave a bottle of water under the sun or in a car for a long period of time, the plastic produces a chemical called BPA. This chemical can cause heart disease and cancer.

A.What about plastic water bottles?

B.They can make you get sick more easily.

C.Is it safe for you to drink the water later?

D.But you may find that it tastes strange.

E.Some people prefer to drink water from rivers.

F.You might want to drink it the next morning.

G.This is OK—however, tap water cannot be stored for a long time.

Do you know that over ten million American kids go to camp every summer? 1.Back then, before the air conditioner was invented, hot city summers were uncomfortable and even unhealthy for children, so escaping to the country for a few weeks became a popular trend.

Today, kids have different reasons for making camp a part of their lives, such as:

To meet new people

Camp might give you a chance to be with people from different states, or even different countries. It’s a great way to make new friends and learn about different places and cultures. Michiko, 13, put it like this:“I loved camp. I met this girl name Manny who lives in New York (I live in New Jersey) and she is cool. 2. We taught each other words. We liked to swim in the pool a lot.”

To challenge yourself

　 3. Fresh challenges — like trying new sports, learning new crafts and games, or pushing yourself to achieve something — can be very rewarding. Take it from Arabella, 13, who told us: “ I went to summer camp and I passed my swimming test! I can hardly swim, so it was a big accomplishment (成就). 4.　 ”

To appreciate nature

There’s a great big natural world out there, and going to camp helps you learn how beautiful and important it really is. 5. Getting out into the woods or mountains can give you a better understanding of how the web of life works.

A. Not all the things that kids do at camp are easy.

B. She speaks Spanish and I speak Japanese.

C. I felt great afterwards.

D. It’s also a great way to learn about teamwork and tolerance(包容).

E. Summer camp has been a U.S. tradition for over 150 years.

F. When you get right down to it, going to camp is all about having a good time.

G. Without trees, soil, water, and wildlife, the Earth couldn’t survive.

高一英语单项填空中等难度题查看答案及解析

Have you ever heard the old saying, “Never judge a book by its cover.”? This is a good rule to follow when trying to judge the intelligence of others. Some people have minds that shine only in certain situations. A young man with an unusual talent in writing may find himself speechless before a pretty girl when he speaks. He may not be able to find the right words. But don’t make the mistake of thinking him stupid. With a pen and paper, he can express himself better than anybody else.

Other people may fool you into overestimating(过高估计) their intelligence by putting up a good front. A student who listens attentively and takes notes in class is bound to (一定会) make a favorable impression on his teachers. But when it comes to exams, he may score near the bottom of the class.

In a word, you can’t judge someone by appearance. The only way to determine a person’s intelligence is to get to know him. Then you can see how he reacts to different situations. The more situations you see, the better your judgment is likely to be. So take your time. Don’t judge a book by its cover.

1.The passage suggests that ______.

A.　 a speechless person always writes well

B. a good writer may not be a good speaker

C. a good writer is always a good speaker

D. a good writer will find himself speechless

2.According to this passage, a student who listens attentively and takes notes in class ______.

A. is an intelligent student

B. will not be a good student

C. will score best in exams

D. may not be an intelligent student

3.The passage suggests that we should judge a person’s intelligence through ______.

A. his teachers

B. his behavior in the classroom

C. his reactions to different situations

D. his appearance

4.The writer of this passage wants to tell us not to______.

A. judge a book by its cover

B. make the mistake of thinking a young man stupid

C. overestimate a student’s intelligence

D. judge a person’s intelligence by his appearance

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

1．Get to bed and go to sleep.Your performance，attention，and the ability to concentrate are damaged by lack of sleep.Teenagers need nine to ten hours of sleep a night for best performance.

2．Feed your head.The brain runs badly if it doesn’t get enough fuel.That means protein(蛋白质)and complex carbs (复合碳水化合物)－eggs and wheat bread for breakfast，say，rather than sugary cereal(含糖的麦片粥)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 is brain exercise.Body exercise really improves brain performance，perhaps because it increases blood flow，or perhaps because it reduces stress and anxiety(焦虑).Twenty minutes of activity a day that raises your heart rate will do great good.

4．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.Scientists aren’t sure why.Whatever the reason，the teenage years are the time to learn new languages and master other lifelong skills.

5．Learn the power of risk taking.Adults are always worried about the downside of teenage risk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.

6．Learn what you love.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.

1.According to the passage，teenagers should have　　　for breakfast.

A．wheat bread and eggs                    B．sugar and orange juice

C．sugar and bread                        D．wheat bread and orange juice

2.Body exercise plays a part in all the following EXCEPT　　　.

A．making people less anxious                B．raising heart rate

C．reducing blood pressure                  D．reducing stress

3.The underlined word “downside” in the passage probably means　　　.

A．excitement                            B．disadvantage

C．benefit                               D．power

4.It can be learned from the passage that　　　.

A．teenagers learn quickly when they are fond of something

B．teenagers should be forbidden to drive

C．scientists know why teenagers have a good memory

D．teenagers need less sleep than adults
