Next Stop: Planet Mars
Fly me to the moon? That’s not far enough. On September 14, 2011, NASA released designs for a superrocket, the Space Launch System (SLS). This time the final destination will be Mars.
The SLS is a huge, liquid-fuelled rocket. If it is fully developed, it will be the most powerful rocket ever built. Its lift capability will be much bigger than that of the space shuttle of Saturn 5, the rocket that sent the Apollo missions to the moon.
NASA is planning to launch its first unmanned test flight in 2017. It is hoped that the first crew will fly in 2021 and astronauts will make it to a nearby asteroid(小行星) in 2025. NASA hopes to send the rocket and astronauts to Mars from the asteroid by the 2030s, according to the Associated Press (AP).
NASA used liquid rockets to send Apollo, Gemini and Mercury into space, but later changed to solid rockets boosters(助推火箭) because they were cheaper. Tragically, however, a booster flaw(缺陷) caused the space shuttle Challenger to crash in 1986. The new project plans to return to liquid fuel.
According to AP, the rockets will at first be able to carry 77 to 110 tons of payload(净载重量). Eventually they will be able to carry 143 tons into space, maybe even as many as 165 tons, NASA officials said. By comparison, the Saturn 5 booster could lift 130 tons and the space shuttle just 27 tons.
However, unlike reusable shuttles, these powerful rockets are mostly one use only. New ones have to be built for every launch. This will be very costly.
NASA estimates that it will cost about $3 billion (19 billion yuan) per year, or $18 billion until the first test flight in 2017. NASA hopes to make money by allowing private companies to send astronauts to the International Space Station like giant taxi services, so that the program can be “sustainable”.
“This is perhaps the biggest thing for space exploration in decades,” said Senator Bill Nelson, a former astronaut. “The goal is to fly humans safely beyond low-Earth orbit(轨道) and deep into outer space where we cannot only survive, but one day also live.”
【小题1】What is the outstanding feature of the SLS?

A.It’s equipped with an advanced control system.
B.It’s the first unmanned space shuttle in the world.
C.It’s the only vehicle that can fly astronauts to the moon.
D.It can send a lot more goods and passengers into space.
【小题2】What is Saturn 5?
A.An aircraft that had a deadly flaw and crashed in 1986.
B.A series of rockets that once sent astronauts to the moon.
C.An unmanned space shuttle that was once famous in the world.
D.A kind of launch vehicle that will be used to carry astronauts to Mars.
【小题3】NASA plans to use liquid fuel in the new project because ______ than solid rockets boosters.
A.it is less costly
B.it is much safer
C.it can last longer
D.it is more environmentally friendly
【小题4】According to NASA’s schedule, it will take ______ years to fully complete the SLS program.
A.about 6B.about 10
C.less than 14 D.more than 19
【小题5】It can be inferred from the passage that ______.
A.the SLS program is planning to make reusable rockets
B.the goal of the SLS program is to enable humans to live on the moon
C.the US government may not have provided enough money for the SLS program
D.NASA will use SLS as a space taxi between the Earth and Mars

In the near future, people in some parts of the world will watch a new kind of television. It is called the high definition television or the HD-TV. The main difference between an HD-TV and a normal television is the picture. It is more clear and detailed. This is because the HD-TV has many more points and lines that make a television image. Every color television picture contains thousands of red, green and blue points. They all come together as an image in the eye of the person watching. The points are organized in lines that go across the television screen. There are more than five hundred lines in a normal television. The HD-TV has two times as many. To get this clear picture, you must have a big screen. Experts say people using a small screen will see little difference.

The HD-TV also has clear sound. It is like the sound on a CD. All these improvements make an HD-TV very costly. One kind in Japan now sells for more than twenty thousand dollars .A major problem with the HD-TV is its broadcast signal(传播信号.The signal is bigger than normal because it carries more electronic information.

1. What is the main difference between an HD-TV and a normal television?  It is        .

A.the picture        B.the shape         C.the voice          D.the weight

3. How many lines does an HD-TV have?

A.Over 250                             B.More than 500

C.More than 1,000                        D.About 250

4. What should you do if you want to get a clear and detailed picture from an HD-TV?

A. You must have the bigger signal for the HD-TV. 

B. You have to get a big screen.

The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the America from being discovered by the people of Europe.
Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to “the edge of the world” . Sailors were afraid that they might sail off the earth. Another idea was that at the equator(赤道) the ocean would be boiling hot.
The Atlantic Ocean is only half as big as the Pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2,00 miles (3,200 km) wide.
Two things make the Atlantic Ocean rather unusual. For so large an ocean it has few islands. Also, it is the world’s saltiest ocean.
There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more water was brought to it by rivers, it would take the ocean about more than 4,000 years to dry up. On the average, the water is a little more than two miles (3.2km) deep, but in some places it is much deeper. The deepest spot is near Puerto Rico. This “deep” measures 30,246 feet---almost six miles (9.6km).
One of the longest mountain ranges of the world rises from the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands.
Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels(船) the crew were afraid they would be becalmed (can’t move) here. Sometimes they were.
Today the Atlantic is a great highway. It is, however, not always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the far North across the paths of ships.
We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!
61. What caused people to be unwilling to explore the Atlantic?
A. There were no ships big enough to get across the Ocean.
B. Sailors were afraid of being lost in the Ocean.
C. The Atlantic Ocean was very unusual because it has few islands and the saltiest water.
D. Many incorrect ideas such as “the edge of the world”, “the equator with boiling hot water” made people think the Ocean was full of danger.
62. What is the main idea of the fifth paragraph?
A. How deep the water is.        
B. How to measure the water in the Atlantic.
C. How much water the ocean holds.             
D. How rain affects the Ocean water.
63. What does the underlined word “highway” mean?
A. High road      B. Broad way      C. Fast road           D. Main water way
64. Why does the writer think “this big ocean seems to have grown smaller”?
A. The water in the ocean is becoming less.
B. We have more and more advanced traveling tools now
C. The distance between the ocean and us is shorter.
D. The steamship has a higher speed.

根据短文内容,从下框的A—F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余项.
A.Join learning communities and help each other.
B.Expect problems, never be disappointed, and gradually you’ll make it.
C.Anytime is learning time.
D.Get interested and arouse(唤起) your desire for knowledge.
E.Cover the same ground from different angles(角度).
F.Try to be a good and effective learner.
As a student, how we can learn our lessons effectively is a common problem which is always puzzling us.If you follow suggestions below, I'm sure you'll find the solution easily.
【小题1】Your interest in the subject is the essential driver of success. You can' t learn what you do not want to learn. Emotion is an important part of the learning process. If you are even moderately interested in a subject, give yourself a chance. The key is to get started. If you can create some pleasurable routines, you may find that the subject grows on you. You must always remember learning is just like eating. You don' t expect to enjoy your food without appetite(食欲).Therefore, you should always try to arouse your interest and desire for knowledge if you want to learn well.
【小题2】Don't expect to understand things, or remember too much, the first time you study them.Think about what problem you will meet with in your study, so that you are well-prepared for it. Never be disappointed no matter what happens. Trust that things will get clearer as your brain comes to get new information. It is like a jig-saw puzzle or a cross-word puzzle(纵横填字游戏). As you start to put the pieces together, or string the words together, the full picture becomes clearer. The brain learns all the time, but on its own schedule.Learning does not take place according to a schedule laid down by a curriculum or teacher. Keep at it, and you will gradually find that things that seem difficult at first, will become second nature with time.
【小题3】Your brain is struggling to form patterns to cope with new input from your learning activities.Sometimes, no matter how long you focus on one subject, your brain is not going to pick it up.If you are stuck, move on.Then cover the same general information from a different source, a different book, or a blog, or an online lecture or a video.Try to become a grazing learner, wandering about the countryside, rather than a feed-lot learner, just standing there in one spot, chewing the same bale of hay.The broader your base, the easier it is to learn.Just as the "rich get richer" , the more you know, the more you can learn.
【小题4】Take full advantage of the Internet, blogs, and various mobile devices, not to mention good old-fashioned books and magazines.Learn during "dead time". Listen in your car, on the train, or while jogging. Have your learning with you while waiting in the doctor's office, or listen while checking out at the supermarket. Anytime is learning time.Remember, you are learning through exposure, not by nailing things down. It is more like moisture accumulation in a cloud, rather than building a brick wall.
【小题5】The "loneliness of the distance learner" is a thing of the past.Join a learning community on the web, where members share their knowledge and experience. Search for the communities that suit your interests and learning styles. You will find encouragement, advice and stimulus from fellow learners, as well as from tutors, teachers and coaches.In these communities, you can measure your progress against your own goals, or compare your experience with that of other learners.You can even teach and help others, which is a great way to learn.
