Generations of Americans have been brought up to believe that a good breakfast is one of life essentials. Eating breakfast at the start of the day, we have all been told, and told again, is as necessary as putting gasoline in the family car before starting a trip.
But for many people the thought of food first in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. During the past ten years the number of people who didn’t have breakfast, have increased by 33 percent.
For those who feel pain of guilt about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast. “Going without breakfast does not affect performance,” said Arrold E. Bender, former professor of the nutrition at Queen Elizabeth College in London, “nor does giving people breakfast improve performance.”
Scientific evidence linking breakfast to better health or better performance is surprisingly not enough, and most of the recent works are about adults, not children, “The literature”, says one researcher, Dr. Erresto at the University of Texas, “is poor”.

From the first use of the rocket to carry satellites into space to the setting up of space stations, human beings have been putting great effort into space research. And so far, we have achieved many successes. But there are still numerous tasks in front of us and we should not stop trying to progress.
The international space station (ISS) is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word, if we want to explore space more, the first thing we should do is to set up a space station.
As the space station costs a lot of money, it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone，and it has tried to do so, but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyone’s effort and will benefit everyone.
Led by the U.S. and Russia, the ISS is a joint project between six space agencies involving 16 countries. Called the greatest achievement in human cooperation, the ISS has come to the end of a ten-year’s hard work in construction. China has applied for participation in (taking part in) the project many times. Unfortunately all the applications were rejected, which drove China onto the path of independent development. As the Long March Ⅱ-F/T1 carrier rocket blasted off (leave the ground) and successfully carried the Tiangong-1 into space on September 29, 2011, China takes a big step toward its Space Station Era.
Some West media suggested that the successful launch of Tiangong-1 would disturb the balance of global space power, raising concerns (关注) about “China threat”. China’s space project is not designed for military (军事的) purpose but for developing space technology to explore space resources and make use of them for mankind’s well-being.From Paragraph 2 we learn that ________.
| A．the necessity of building the international space station is not realized now |
| B．many experiments have been done in the international space station |
| C．the international space station is necessary for people to explore space more |
| D．people have traveled to Mars from the international space station |
Which of the following is NOT a reason for countries’ cooperation in building the international space station?
| A．That it is too far away from the earth. |
| B．That it requires a lot of money. |
| C．That it needs everyone’s effort. |
| D．That it will benefit every participating country. |
The underlined word “aggregated” in Paragraph 3 can be replaced by “________”．
| A．united | B．scolded |
| C．allowed | D．forbade |
China wants to build its space station in order to __________.
| A．show that China can build space station alone |
| B．raise international concerns about “China threat” |
| C．make use of space peacefully for mankind’s well-being |
| D．break the balance of global space power |
As you grow older, you’ll be faced with some challenging decisions—like whether to cut class or try cigarettes. Making decisions on your own is hard enough, but when other people get involved and try to pressure you one way or another it can be even harder. People who are your age, like your classmates, are called peers. When they try to influence how you act, to get you to do something, it’s called peer pressure.
Peers can have a positive influence on each other. Maybe another student in your science class taught you an easy way to remember the planets in the solar system. Maybe you got others excited about your new favorite book, and now everyone’s reading it. These are examples of how peers positively influence each other.
Sometimes peers influence each other in negative ways. For example, a few kids in school might try to get you to cut class with them; your soccer friend might try to convince you to be mean to another player and never pass him the ball.
It is tough to be the only one who says “no” to peer pressure, but you can do it. Paying attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do.
You’ve probably had a parent or teacher advising you to “choose your friends wisely.” Peer pressure is a big reason why they say this. If you choose friends who don’t cut class, smoke cigarettes, or lie to their parents, then you probably won’t do these things either, even if other kids do.
If you continue to face peer pressure and you’re finding it difficult to handle, talk to someone you trust. Don’t feel guilty if you’ve made a mistake or two.For whom is the passage most probably written?
| A．Parents. | B．Teachers. |
| C．Students. | D．Doctors. |
In the last three paragraphs, the author mainly_____.
| A．explains why friendship is so important |
| B．shows how to make more good friends |

Which of following may help handle peer pressure?
| A．Spending more time with classmates. |
| B．Taking up more relaxing hobbies. |
| C．Choosing friends with no bad habits. |
| D．Helping others who are in trouble. |
What is the topic of the passage?
| A．Friendship. | B．Making decisions |
| C．Self-confidence | D．Peer pressure |
I have a friend named Monty Roberts who owns a horse ranch in San Ysidro. He has let me use his house to put on fund-raising events to raise money for youth at risk programs．
The last time I was there he introduced me by saying, "I want to tell you why I let Jack use my house.” It all goes back to a story about a young man who was the son of a horse trainer who would go from stable to stable, race track to race track, farm to farm and ranch to ranch, training horses. As a result, the boy's high school career was continually interrupted. When he was a senior, he was asked to write a paper about what he wanted to be and do when he grew up.”
That night he wrote a seven-page paper describing his goal of someday owning a horse ranch．He wrote about his dream in great detail and he even drew a diagram of a 200-acre ranch, showing the location of all the buildings, the stables and the track. Then he drew a detailed floor plan for a 4,000-square-foot house that would sit on a 200-acre dream ranch．”
He put a great deal of his heart into the project and the next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that read, "See me after class.”Why can the writer use Roberts's house to raise money for youth at risk programs?
| A．Because they are good friends. |
| B．Because the youth has the same dream as Monty Roberts. |
| C．Because Monty Roberts has a poor childhood. |
| D．Because Monty Roberts like to help youth． |
What do you think of Monty Koberts' goal of a horse ranch at that time?
| A．romantic | B．real |
| C．dream | D．false |
What would happen after the teacher gave a note "See me after class.”?
| A．Monty Roberts got very angry at this. |
| B．The teacher would criticize him. |
| C．The teacher wanted to tell him that his dream would come true． |
| D．The teacher would encourage him. |
Mars( 火星) appears to be flowing with small streams of salty water, at least in the summer, scientists reported Monday. "It suggests that. it would be possible for there to be life today on Mars," NASA's science mission chief, John Grunsfeld, said at a news conference on September 28, 2015.
The streams are about 12 to 15 feet wide and 300 feet or more long, scientists said. "What we're dealing with is wet soil. thin layers of wet soil, not standing water," said Aifred McEwen of the University of Arizona at Tueson ! the principal scientist for the Mars Reconnaissance Orbiter's high-resolution imaging experiment.
Because liquid water is essential to life, the findings could have major implications for the possibility of Martian life. The researchers said further exploration is needed to determine whether microscopic life exists on the planet.
The presence of liquid water could also make life easier for astronauts visiting or living on Mars. Water could be used for drinking and for creating oxygen and rocket fuel. NASA's goal is to send humans there in the 2030s.
The evidence of flowing water consists largely of dark, narrow streaks(条痕) on the surface that tend to appear and grow during the warmest Martian months and fade the rest of the year.
Mars is extremely cold even in summer, and the streaks are in places where the temperature is as low as minus 10 degrees Fahrenheit. But salt can lower the freezing point of water and melt ice.
The source(源头) of the water is a mystery. Scientists noted it could be melting ice. It could be an underground aquifer, which is rock or sand that can hold water. It is possibly water vapor from the thin Martian atmosphere, Or it may be a combination.
Michael Meyer, lead scientist for NASA's Mars exploration program, said the only definitive way for now to determine whether there's life on Mars is to collect rocks and soil for analysis on Earth - something a U. S. lander set for lift-off in 2020 will do.What would be the best title for the text?
A Streams of Water Spotted on Mars

We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.
A brain can also simply be a smart person, If a person is called brainy, she is smart and intelligent. If a family has many children but one of them is super smart, you could say, "She's the brains in the family. " And if you are the brains behind something you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.
Brain trust is a group of experts who give advice. Word experts say the phrase"brain trust" became popular when Franklin D. Roosevelt first ran for president in 1932, Several professors gave him advice on social and political issues facing the U. S.These professors were called his "brain trust. "
These ways we use the word "brain" all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word“drain." As a verb to drain means to remove something by letting it flow away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are,sort of,draining out of the country.
However,if people are responsible for a great idea,you could say they brainstormed it. Here,brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.
If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make someone accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.According to the text, if you're the CEO of Bai Du you can be called________.
| A．the brains behind Bai Du |
| B．Bai Du's brain trust |
| C．the brain drain of Bai Du |
| D．the organ of Bai Du |
Why did Roosevelt successfully win the election?
| A．Because he was smart at giving advice. |
| B．Because word experts were popular. |
| C．Because he got his brain trust. |
| D．Because he was the brains behind America. |
Which of the following expression is always used in a negative way?
| A．Brain trust | B．Brain drain |
| C．Brainstorm | D．Brainwash |
