Myth: If you cut your hair, it will grow long faster.

Truth: That’s not true. “Your hair isn’t like a lawn or a rosebush, where cutting can stimulate fresh growth,” says Phillip Kingsley. The length of your hair is genetically determined. When it reaches a certain length, it stops growing. When you clear up the dead split ends, this make your hair look healthier, but not necessarily longer.

Myth: If you skip meals, you lose weight fast.

Truth: There’s no truth in this advice. Not only will you not lose weight by starving yourself, but according to Carol Ann Rinzler, this may actually cause you to gain weight. Rinzler reasons that missing a meal causes your metabolism(新陈代谢) to slow down so that you burn food more slowly. This only makes you feel hungrier and by the time you finally do reach the table you will probably eat more food. Strange as it may seem, studies show that eating several small meals and snacks throughout the day is a more healthy way to lose pounds.

Myth: If you swallow gum,it will stay inside your stomach for seven years.

Truth: Actually, it takes just a few days for gum to make its exit---not seven years, says NeiIzenberg, M. D., editor of Kids Health Organization. But because gum is made of the same thing as rubber, it cannot be fully digested in your stomach--- so if you gum up the works on a regular basis, you might find yourself in a sticky situation.

Myth: The best way to stop a nosebleed is to lift your head back.

Truth: Now that’s bad advice. Bloody noses are caused by broken blood vessels, so while lifting your head back might stop the fluid from rushing out of your nose, it won’t stop the bleeding; you’ll just end up swallowing lots of blood. Your best bet “Rest quietly. Don’t poke or pick, and the blood will naturally clot (凝结成块) within a minute or two”, suggests Dr. Izenberg.

Walking down a path through some woods in Georgia, I saw a small pool of water ahead on the path. I changed my direction to go around it on the part of the path that wasn’t covered by water or mud. As Ireached the pool, I was suddenly attacked! Yet I did nothing for the attack. It was so unpredictable andfrom somewhere totally unexpected. I was surprised as well as unhurt though I had been struck four or fivetimes. I backed up a foot and my attacker stopped attacking me. Had I been hurt, I wouldn’t have found itamusing. And I was laughing. After all, I was being attacked by a butterfly!

Having stopped, laughing, I took a step forward. My attacker rushed me again. He charged towards me at full speed, attempting to hurt me but invain. For a second time, I took a stepbackwards while myattacker paused. I wasn’t sure what to do. After all, it’s just not everyday that one is attacked by a butterfly. I stepped back to look the situation over. My attacker moved back to land on the ground. That’s when I discovered why my attacker was charging at me onlymoments earlier. He had a mate andshe wasdying.

Sitting close beside her, he opened and closed his wings as if to fanher. I could only admire the loveand courage of that butterfly in his concern for his mate. He had taken it up on himself to attack me forhis mate’s sake, even though she was clearly dying and I was so large. He did so just to give herthose extra few precious moments of life. His courage inattacking something thousands of times larger and heavier than himself just for his mate’s safety seemedadmirable. I couldn’t do anything other than reward him by walking on the more difficult side of the pool. He had truly earned those moments to be with her, undisturbed.

Since then, I’ve always tried to remember the courage of that butterfly whenever I see huge barriers facing me.

NASA on September 28, 2015 announced the strongest evidence yet for liquid water on the red planet, increasing the possibility that astronauts journeying to Mars could someday rely on the planet's own water for their drinking needs.

You may feel like you've heard about the hunt for liquid water on Mars before—and the researchers involved know it may seem played out. But science has yet to truly prove that water flows on Mars once and for all, and doing so could completely change the way we view the planet. This new data is a big step in the right direction.

"Liquid water is an attractive topic, and we like the thousandth time someone has discovered water on Mars," Lujendra Ojha, the Georgia Tech PhD candidate who led the research announced Monday, told The Post. But there's a good reason that liquid water is so "attractive": Mars is now the only planet in our solar system to show evidence of the stuff on its surface, other than our own. Other worlds have it in subsurface oceans, or scattered around as vapor in the atmosphere. But Mars is the only place where we have solid evidence for liquid that sits right there in the open air. While it would be a major leap to suggest that Mars might harbor life—even microbial life—liquid water at least makes it possible that parts of the planet are habitable.

The study builds on research from April, when scientists using data from the Curiosity rover noted that the planet had the seasonal potential for liquid water. We know that because of the extremely low pressure on Mars, water has a boiling point of just a few degrees Celsius, after which it evaporates. The April study noted the presence of perchlorates (高氯酸盐) —a kind of salt—which could make the boiling point of Mars' water much higher, theoretically allowing it to remain liquid. They affirmed that the planet's temperature would be right for liquid, perchlorate-filled water to form every day during winter and spring.

1.What does the Paragraph 2 mainly tell us?

A. The significance of the discovery.

B. The doubt of the discovery.

C. The difficulty of the discovery.

D. The expense of the discovery.

2.The underlined words "our own" in Paragraph 3 refer to ________.

A. Mars

B. the earth

C. liquid water

D. the solar system

3. What plays an important role in making Mars' water in the state of liquid?

A. The thick atmosphere around Mars.

B. The physical structure of Mars.

C. The extremely low pressure on Mars.

D. Perchlorates in Mar's water.

4. The best title for the passage can be "________".

A. Water on Mars could be used for dringking

B. There might be some kinds of life on Mars

C. NASA would send astronauts to journey to Mars

D. NASA confirms the best-ever evidence for water on Mars

Some experts feel that cars are certain to fall into disuse. They see a day in the not-too-distant future when all cars will be deserted and made useless. 1. They hold that the car will remain a leading means of city travel in the foreseeable future.

The car will undoubtedly change greatly over the next 30 years. It should become smaller, safer, and more practical, and should not be powered by the gas engine. 2.

Unless changes take place in the power system, the car in the future will still be the main problem in city traffic jams. 3.

When the car enters the highway system, a small arm will drop from the car and connect with a rail, which is similar to hose(软管) powering subway trains electrically. Once joined to the rail, the car will become electrically powered from the system and control of the car will pass to a central computer. 4.

The driver will use the telephone to dial instructions about his position and the place he heads for into the system. The computer will find the best way and reserve space for the car all the way to the correct exit from the highway. ____5. It is believed that an automated highway will be able to deal with 10,000 cars per hour, compared with the 1,500 to 2,000 cars that can be carried by a present-day highway.

A. The driver will be free to relax and wait for the call that will warm him of his coming exit.

B. Other experts however think the car is here to stay.

C. The car of the future should be far more pollution-free than present types.

D. There will be plenty of policemen on the highway to control the traffic.

E. One suggested solution to this essential problem is the automated (自动的) system which seems to hold water.

F. The computer will then monitor all the car’s movements.

G. All of the experts don’t know what will happen in the future.

When going through major life changes, like changing careers, I would change the people with whom I spent the most time. We’ve all gone through periods when the people in our lives have changed—graduation, moving to a new city, getting a new job, joining a new club, etc. I don’t think I need to convince you just how much influence other people can have over your identity. If you’ve ever experienced a major switch in your people environment, then you know that you change as well.

Most people don’t make these choices consciously, though. You might consciously decide to spend more time with a certain friend, or you may ask someone out on a date to begin a new relationship. But few people choose their existing friendships deliberately.

There’s no “getting rid of people”. People are always dropping into and out of each other’s lives. Associations grow into friendships, and friendships fade into associations. You don’t get rid of anyone. The truth is that in order to make room for new people and new experiences, you may need to loosen up some of your existing connections.

What about loyalty? Shouldn’t you always be loyal to your friends? Once you have a close friend, even if his influence on you is slightly harmful, shouldn’t you stick by him?

Loyalty to a friend sometimes means having to let go. It means being loyal to his highest and best self as well. If someone is destroying his health by smoking, for example, you aren’t showing loyalty by smoking right along with him. True loyalty sometimes requires that you break damaging connections, get yourself back on solid ground, and then decide what you can really do to help your friend.

It can take a lot of courage to tell someone, “I’m sorry, but I can’t have you in my life anymore.” But even though this might seem like a selfish act at times, it’s often the best thing for the other person, too. If a relationship is holding you back in some way, understand that it’s also hurting the other person. For example, if you work for a violent boss, your acceptance of that situation is considered to be silent approval, encouraging your boss to continue to behave violently.

1.When experiencing major life changes, people may _______.

A. join a new social community

B. influence their friend around

C. choose their friendships purposely

D. have their people environment changed

2.What does the underlined sentence in Paragraph 3 mean?

A. Everyone has at least one friend.

B. It is unnecessary to make new friends.

C. Friendships still exist though there are fewer connections.

D. You ought to treat your old and new friends equally.

3.What is the author’s opinion on the loyalty to friends?

A. Never betray your close friends whatever happens.

B. Correct their mistakes while you guard their goodness.

C. Stick by your friends even though they do harm to you.

D. Break up with your friends immediately if they smoke.

4.How should we behave when employed by a violent boss?

A. We should accept what we are told to do.

B. We should stay silent and be in favor of him.

C. We should bravely disobey him if he is wrong.

D. We should give our boss courage to continue.
