In summer, millions of people will head for the beach. And while the ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．”
Scientists are working on using that energy to make electricity．
Most waves are created when winds blow across the ocean．“The winds start out by making little ripples (波纹) in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ”Taylor said．“Waves are one of nature’s ways of picking up energy and then sending it off on a journey．”
When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (涡轮) ．The turbine can then power an electrical generator (发电机) ．
The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland．
The resource is huge．We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal．
Oceans cover three quarters of the earth’s surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．
Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus, wave power would get in the way of fishing and boat traffic．
With more research, however, “many of these problems might be overcome,” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．”
In the future, when you turn on a light switch, an ocean wave could be providing the electricity!
68．Which of the following is NOT true?
A．Wave power costs too much money．
B．Wave energy creates the same amount of pollution as other energy sources．
C．Wave power affects fishing and boat traffic．
D．Wave power may affect marine animals．
69．We can infer from the passage that ______．
A．finding more new energy sources is not necessary because of wave energy
B．wave energy is a resource that will never run out and is used all over the world
C．wave power is perfect for creating energy around the world
D．wave power doesn’t create any pollution
70．The underlined word “drawbacks” probably means ______．
A．regrets B．adventures C．disadvantages D．difficulties
71．What can be the best title for the passage?
A．How to Get Electricity by Waves． B．The Advantages of Wave Energy.
C．Can Waves Make Electricity? D．The Disadvantages of Wave Energy．
Most people give little thought to the pens they write with, especially since the printers in modern homes and offices mean that very things are hand written. All too often, people buy a pen based only on
, and wonder why they are not satisfied
they begin to use it. However, buying a pen that you’ll enjoy is not
if you keep the following in mind.
First of all, a pen should fit comfortably in your hand and be to use. The thickness of the pen is the most important characteristic
comfort. Having a small hand and thick fingers, you may be comfortable with a thin pen. If you have a
hand and thicker fingers, you may
a fatter pen. The length of a pen can
influence comfort. A pen that is too
can easily feel top-heavy and unstable.
Then, the writing point of the pen should the ink to flow evenly（均匀地）while the pen remains in touch with the paper.
will make it possible for you to create a
line of writing. The point should also be sensitive enough to
ink from running when the pen is lifted. A point that does not block the
may leave drops of ink,
you pick the pen up and put it down again.
, the pen should make a thick, dark line. Fine-line pens may
bad handwriting, but fine lines do not command
next to printed text, as,
, a signature on a printed letter. A broader line, on the other hand, gives an impression of confidence and authority（权威）.

Would you want a doctor who got high marks in medical school just for trying hard? Apparently many college students would have no problem with that. They believe students are owed a good grade simply because they put a lot of effort into a class.
The researchers asked more than 800 undergraduates if they agreed or disagreed with some statements. For example: "If I have completed most of the reading for a class, I deserve a B in that course." And: "A professor should not be annoyed with me if I receive an important call during class."
Just16 percent thought it was OK to take that phone call. But 66 percent agreed that a professor should consider effort and not just the quality of a student's work when deciding grades. And 40 percent thought they should get a B, the second highest mark, just because they did most of the reading for class.
Some experts are not surprised that students often see no difference between effort and results. Social critics like to say that in children's activities these days everyone gets an award just for trying, so no one will feel rejected.
Yet competition to get into the best colleges is fiercer than ever. Students may worry that low grades will keep them out of graduate school or a good job.
And there may be another explanation: pressure from parents to get a good return on the family's investment. These days, college can cost more than a house.
A former teaching assistant recently wrote to the New York Times about his experience with grade expectations. He would try to explain it this way when students asked for a top grade just for studying hard in chemistry class:
What if a baseball player came to spring training and worked harder than all the others, but still could not play well? Would the team accept him anyway, just because he tried so hard?
The students would say no. But most of them would still ask for an A.What does the passage mainly discuss?
| A．How students can get a good grade in the course. |
| B．Whether students are allowed to answer calls in class. |
| C．Whether students deserve high marks just for trying hard. |
| D．Why students put a lot of efforts in their studies. |
According to the research, most of the students _______.
A. thought it was all right to answer the call during class.
B. objected to deciding grades only by the quality of a student’s work.
C. thought they did most of the work for class and should get a B.
D. agreed that they should be given top grades because of their hard work. Which of the following opinions do social critics agree to about children’s activities?
| A．Those who are active in the activities can get an award. |
| B．Only by playing an important role in the activities can you get an award. |
| C．An award is prepared for anyone who performs best in the activities. |
| D．Whoever takes part in the activities can get an award. |
From the sixth paragraph we can learn that _____.
| A．it costs much more to build a college than to buy a house. |
| B．the costs of studying at college are much more than staying at home. |
| C．the costs of sending a child to college are much more than buying a house. |
| D．it is difficult for parents to send a child to college. |
What does the former assistant want to tell students with the example of the baseball player?
| A．Effort can lead to good results. | B．Effort is very necessary. |
| C．Effort and results are quite different. | D．No good results, effort is unnecessary. |
Here is some news of the future.
March 20, 2035
There was a lot of news around the life extension drugs that hit the market a decade ago. They didn't promise that you would like forever, but they gave you a chance to extend your life an extra five to ten years. Even though the life expectancy rate at birth has increased greatly, the life expectancy for seniors hasn't improved that much. Basically, you have a greater chance to become a senior, but you will not have a much longer lifespan, and this is where the anti-aging drugs intend to kick in. So, do the anti-aging drugs work? Well，it is too early to tell. But the sales so far are very good.
April 19, 2035
Of the total US population of 378 million, people over 65 years of age now make up 20% for the first time. The senior ratio of only 4.1% by year 1900, and 12.4% 30 years ago.
The number of people above 65 compared to those of what is considered working ages, between 15 and 64, is currently 33.7%. This is up from 18.5% since year 2005, which means that for every retired person there are now two workers, compared to four workers 30 years ago. The number of people above the age of 80 has grown to 23.8 million, making them 6.3% of the total population compared to 3.6% in 2005.

When I was learning calligraphy (书法), my teacher told me a story.
A calligrapher taught handwriting. One of his students who often practiced handwriting with old sheets of newspaper complained that he made very little progress though he had learned it with the calligrapher for a long time. His teacher said to him, “Try to use the best paper. Maybe you'll write better.”
The student did as he was told. It really worked. He made headway not long afterwards and felt curious. He asked his teacher about the reason. The calligrapher answered，“When you used old newspaper to practice handwriting, you would think you were writing a draft. It didn't matter if you wrote badly as old newspaper was plenty in supply. In that case you wouldn't pay much attention to it. Now you use the best paper and you'll treasure it. Each time you write you feel strongly about the rarity of chances and you'll devote to it with all your heart and soul; you'll do the handwriting much more attentively than practicing. Of course you've made rapid progress.”
Indeed, we spend our ordinary days just as they are worthless “old newspaper”．We don't care if we scrawl and waste it, thinking that it will come endlessly—the “old newspaper” is inexhaustible. In such a mood we may each day pass by opportunities but fail to catch any of them.
Life is not a military exercise but an actual war in which real weapons are used. In everyday life there's no chance for us to draft. That's because what we call “draft” actually is the answer sheet we write that cannot be changed.
Every day of our life is something new. Let us take every day as a sheet of the best paper.The calligrapher in the story told the student to write on the best paper because he thought ________.
| A．the student would practice more carefully on the best paper |

| D．the student could write more on the best paper |
The student didn't make much progress at first because ________.
| A．he didn't follow his teacher's advice |
| B．he was too poor to buy better paper to write on |
| C．he regarded his writing on old newspaper just as a draft |
| D．he was not used to the calligrapher's teaching manner |
We learn from the passage that ________.
| A．the student finally gave up |
| B．the student made rapid progress by practicing more carefully |
| C．the calligrapher was strict with his students |
| D．old newspaper is not useful |
Which of the following is true according to the passage?

[1]A researcher who helped make crops grow in dry land areas received the World Food Prize last week. Daniel Hillel was recognized for his work in developing what is called “micro-irrigation" or “drip irrigation." It has made farming possible in places where there is little rainfall or water.
[2]Daniel Hillel's farm near his home in Israel shows his ideas at work. “Each tree row is fed by these plastic tubes that drip water at the base of the tree." Watering plants drop by drop has changed agriculture by reducing the amount of water needed to grow crops.
[3]Farmers now depend on drip irrigation in many areas, including vineyards in Spain, onion fields in Africa, and even farms in the United States. Farmers in California grow about fifty percent of the fruits and vegetables of the continental United States. And the reason that is possible is because of these drip and micro-irrigation techniques.
[4]Daniel Hillel was born in California. After his father died, his mother moved the family to Palestine, where her parents lived. The area eventually became part of the state of Israel. Daniel Hillel got his start in dry land farming as a settler in Israel's Negev Desert in the 1950s. “The issue was efficient use of water because land is available and extensive while Water is limited."
[5]Desert farmers were not able to push water through irrigation canals to their crops the way farmers have since ancient times. So Mr. Hillel and others gave plants just what they needed, just where they needed it. The idea was to apply the water little by little. The method worked so well that soon Mr. Hillel was traveling the world, showing others _____.Why did Daniel Hillel win the World Food Prize? ( no more than15 words)
