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.
George Washington Carver had a goal. This was to help southern farmers who needed good crops. They needed crops that didn’t hurt the soil. Carver went to Simpson College in Iowa, in which he studied for three years. Then he went to Iowa State, where he got two degrees. The college knew he was smart and wanted him to stay. So he joined the team. He was put in charge of a huge greenhouse. There he grew over 20,000 kinds of fungi(真菌),which made him famous.
Carver had many job offers. Thomas Edison offered $175,000 a year. Henry Ford tried to hire him too. Joseph Stalin invited him to the Soviet Union to help with cotton. But Carver refused all offers. Instead, he took a job at Tuskegee Institute. This was a school for African Americans. Carver was paid only $1,000 a year. But he was happy because he had goals to reach and he knew he could reach them at Tuskegee.
Carver worked at Tuskegee for 47 years. He never asked for a raise in pay. And he never received one. He worked so hard that he died in his office chair on January 4, 1943.
Carver came up with over 300 products from peanuts (花生), all of which could have been patented (申请专利). He could have made millions. But he did not want to. Here is what he said, “Mr. Creator did not charge to grow the peanut. I cannot accept money for my work with it.”
Through his efforts, Carver set up a fund, for he wanted research to continue. He gave his life’s savings to it, which came to $40,000. One honor came after his death. His birthplace was made a national shrine (圣地). How surprised the modest Carver could have been!

C.Stupid. D.Reliable.
4.What’s the main idea of the text?

C.Carver refused many job offers that would make him rich.
D.Some scientists would rather do good than make much money.
If you are home-alone, or live alone, and somebody comes to the door, shout out “I got it” so that it seems like someone else is there with you and you are not alone. But actually before that, there are lots of preventive(预防的) actions to take.
Give your apartment a safety check
It’s a good idea to give your apartment a once-over for safety concerns—ideally before you even move in. Complete this safety checklist.
Can any of your valuables be seen from the street?
Can you see who’s at the door without opening it?
Do you have all your mail held at the post office when you travel?
Have all the locks of your doors been changed since you moved in?
Become friends with your neighbors
If you’re shy, then you’d probably prefer anything else to chatting with neighbors. But make an effort to be friendly. In one way or another, your neighbors will be more willing to lend a hand to a friend than they are to help out a stranger in times of trouble.
Be smart about spare keys
Thieves and other illegal types know exactly where to check for spare keys.
So don’t think you’re being clever by hiding them in the mailbox, or underneath a carpet. Instead, you had better leave them to a friend or trusted neighbor.
Always lock the door
Lock your doors, every single time. Even if you’re just going to the garbage dumpster(垃圾大铁桶) quickly, or only stepping inside to catch something you forgot.
It may seem like overkill — especially if you live in a relatively safe district. But it only takes that one moment for someone to steal in.
1.Why does the author advise you to shout “I got it” in Paragraph 1?
A.To protect yourself. B.To answer the door.
C.To call out loudly. D.To welcome the guests.
2.What is the author’s opinion about spare keys?
A.Hide spare keys in the mailbox.
B.Take all the keys with you if possible.
C.Leave the keys to someone you trusted.
D.Have your keys ready as you leave.
3.What are the right preventive actions?
① Never change the locks.
② Close the door in time.
③ Make friends with neighbors.
④ Put spare keys under the carpet.
⑤ Keep valuables seen from the street.
⑥ Have a safety check about the apartment.
A.①②④ B.②③⑤
C.③④⑥ D.②③⑥
Once upon a time there lived a wise king who wanted to marry off his favorite daughter. He wondered how he could find the right person. The king had an idea. He decided to hold a competition to decide which gentleman would win this great honor. The king announced that anyone who wanted to marry the princess must report to the palace. To win his daughter, a man must fill up a whole room with a light thing very quickly.
The first brave competitor arrived at the palace. His name was Peter. He brought bags full of feathers. With great confidence, he started to fill the large room with feathers, but time ran out and he failed.
The next day, another young man whose name was Bob tried to quickly fill the room, this time with beautiful silk. Time ran out again, and he left the palace disappointed.
The competition went on day after day. Hundreds of competitors hoped to pass the test but no one succeeded. The king began to feel hopeless. Wasn’t anyone in the kingdom qualified to marry the beautiful princess?

In general, our houseparents are annoyed for boys students in dormitories. I didn't begin to like our houseparents until one night in last week. I was asleep when my alarm clock drops onto the floor and were broken into pieces. After the while, the houseparent on duty opened the door and rushed in. Instead blaming me, he asked me anxious what was going on. Before making sure I was OK, he asked me to go back to sleep and cleaned up itself. Since then, I have completely changed my opinion of our houseparents. They are like our parents, kept all of us safe.
