The other day I heard a few local musicians talking, "I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm (韵律).""Nobody wants to pay musicians anything. I’m sick of all the people who want you to play without paying you.” One younger musician said, "There are a couple of clubs who want me to play for a few nights a month, and I’m trying to find other places to play. I’m also planning to join in several summer festivals this year." I really liked what the younger musician said so I made friends with him.
Attitudes are important. Whether they’re positive or negative (消极的), they’re all rubbing off on you. If you’re around people who are always complaining(抱怨) or blaming (责备) others, it is possible that you will start doing the same as well. If you spend lots of time with people who don’t support your dreams, it is time to take a look at the people you call "friends".
There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative people on your list. Set a new standard for yourself and don’t become friends with people who fall below that standard. The choice is always yours to make. Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream.
The musicians’ conversation at the beginning is to show that ______.

A．musicians’ living conditions are not good

B．people in that town have poor taste in music

C．different people have different attitudes

D．young people are more likely to succeed

The underlined part "they’re rubbing off on you" in Paragraph 2 means ______.

A．they’ll push you ahead	B．they’ll have an influence on you
C．they’ll keep you from moving on	D．they’ll help you realize your dreams

A．make the right kind of friends

B．improve your ability to make friends

Recently, a scientist did some experiments．He left a group of 4-year-olds in a room with a bell and a candy．If they rang the bell, he would come back and they could eat the candy．If, however, they didn't ring the bell and waited for him to come back on his own, they could then have two candies.
In videos of the experiment, he can see the children kicking, hiding their eyes--trying to exercise self-control so they can wait and get two candies．The results are different．Some broke down and rang the bell within a minute．Others lasted 15 minutes.
The children who waited longer went on to get higher SAT scores．They got into better colleges and had better adult success．The children who rang the bell quickest were more likely to have received worse teacher and parental evaluations （评价） 10 years later and were more likely to have drug problems at age 32.
The experiments are worth noting because people spend a lot of time thinking about how to improve education, how to become rich．But when the result is not good, they will come back to ask "how do we get people to get the sort of self-control that leads to success?" This is to enter the world of human nature.
So these experiments along with everyday experience, tell us that self-control is most important．Young people who can sit through sometimes boring classes to get a degree can work hard in order to learn a language well．They can avoid drugs and alcohol．For people without self-control skills, however, school is a series of failed ordeals（煎熬）．No wonder they drop out and their later life is a group of foolish ideas, such as drug use, stealing and so on.
The scientist did some experiments to .

A．test children's self control and later success

B．test children's intelligence of ringing the bell

C．find good ways of training children to learn

D．prove that children's education is important

We can learn from the experiment that

A．all children tried to ring the bell for more candies

B．some children didn't get any candy in the end

C．the children have different self- control

D．the last one to ring the bell is most successful

What is the best title for this passage?

A．Ways of self-control training

B．Experiments on children's ringing the bell

C．Higher score, better achievements

D．Self-control is the key to success

Do other countries’ students also have so much homework? What do they usually do in their free time? You may feel curious about them.

Once in a village, the villagers built a new church building and people came from far and wide to see it. They admired its beauty! They said it was the most beautiful building in the world. Up on the roof, a little nail（钉子）heard the people praising everything about the lovely structure – except the nail! No one even knew he was there, and he became very angry and sad.
“If I am not important, nobody will miss me if I quit!” So the nail then released (松开) its hold, got down from the roof, and fell into the mud.
That night it rained and rained. Soon, the board that had no nail was blown away, and the roof began to leak (漏水). The water flowed down along the walls and over the beautiful pictures on the walls. The plaster (石膏) began to fall, the floor was ruined, and the Bible was also ruined by water. All this was because a little nail decided to quit!
But what of the nail? While holding the board, it was not known by others but it was useful. Buried in the mud now, it was useless and would soon be eaten up by rust!
What the story wants to say is that every member is important to a whole group!
You may, like the nail, feel not important at times, but just like the nail, your absence is felt. A big building might fall to pieces. You are important to a group even if you are small.
Why did the nail decide to quit?

A．Because he was not able to hold on any longer.

B．Because he was angry and sad without people’s praising him.

Can you remember a morning when you’ve woken up to the ring of your alarm clock and wished you could stay in bed? You haven’t slept well, your hair is a mess. Worse, you can’t stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary(无意识的,不自觉的) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds.
The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren’t. There are many ideas explaining why we yawn.
One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more.
Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed.
A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. “Brains are like computers.” he said. “They only operate efficiently and effectively when they’re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat.”
Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup（打嗝）, that they can’t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response!
What’s the purpose of the description of how bad you may feel when you’re woken up in the morning?

A．To explain why humans yawn.

B．To explain how humans start yawning.

C．To lead into the topic of yawning.

D．To complain about being woken up by the clock.

Which is not among the possible reasons for yawning mentioned in the passage?

A．A way to show that you feel hot.

B．A way to get rid of carbon dioxide.

C．A way to cool off your brain.

D．A way to communicate.

In which situation are you likely to yawn?

A．When you feel frustrated.

B．The weather is hot.

C．Someone else yawns near you.

D．When you breathe in a lot of carbon dioxide.

What can we learn from the passage?

A．The real reason why humans and most animals yawn.

B．Hiccups are an involuntary human action similar to yawns.

C．The more an action can be studied, the easier it is to research.

D．Finding out why humans yawn should be easier than sending people into space.

Is veg food healthier than non-veg food? I feel this is a very common topic that people speak on．Please give me your opinions on this topic．
Rao 12-18-08	So far as veg food is concerned, it is also proved to be a healthy and nutritious diet, but has very few items which can provide us with proteins, but if you see non-veg food like eggs, chicken, and many more, such foods have a large content of proteins in them.
Sai 12-19-08	Man basically is herbivorous（食草的）. If we look at the animal kingdom We can see that all the herbivorous animals have the similar dental（牙齿的） structure, which clearly shows that the human being also ought to be vegetarian by birth. It is only the living conditions that make man carnivorous（食肉的）. The vegetarian foods are easily digestible.
Santos 12-20-08	Non-veg food items are better than veg items. A healthy person requires complete diet and veg + meat makes the diet complete. The only caution that needs to be taken is not to have non-veg items on a daily basis. Once in a week or couple of weeks will be best.
Krishna 01-03-09	When we eat non-veg, we are all veg by nature. The chicken that we eat feeds on grains, the mutton that we eat feeds on grass, and the fish that we eat feeds on simple plants. So non-veg food by logic（逻辑）is better and suited for hauman beings.
Khan 01-05-09	Non-veg food is equally important in our diet as it helps in many ways, especially fish and other seafood as fish contains omega 3 which makes our immune system（免疫系统）stronger. Do you know that most of the veg food put together does not contain as much omega 3 as fish alone contains!

A．It damages our immune system.	B．It has few nutrients.
C．It contains too much omega 3.	D．It is lacking in protein.
