While I was in 9 th grade, I built a circuit (电路装置) for the traffic system of our city. After getting the first prize. I got this valuable advice from my father; “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.”

I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (编码). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I  kept working and discussed with my professor, I became more comfortable and those “how ”questions soon turned into “what if I do this and that” types of questions.

It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He has headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem.

My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project.

I had this exchange with my 6-year-old last week.

       Him: Mom, we have to start buying Danimals.

       Me: Why?

       Him: So, I can bring it to |school for lunch.It's yogurt .

       Me: Why do you want it so badly?

       Him: Because Danimals i|s giving away five fantastic Caribbean vacations.

       I had to explain that there was little chance that he would win a vacation.It's a strategy used to encourage kids to beg for artificially-colored (人工着色的) yogurt that costs a lot.

       Marketing follows my kids —and yours—wherever they go .It comes via TV commercials. Store displays and websites are also constantly selling at our kids .But the most powerful means in kids" lives is the presence of licensed characters on every product imaginable.

       Children can begin their day in character clothing.There's even character -themed wall paint available.A breakfast in a character bowl can be followed by a character toothbrush and character toothpaste(牙膏), character soap and shampoo, and a character wash cloth and towel .Then, they can put on character clothing and character shoes.Check that, character clock on the wall: Is it time for characier-shaped fruit snacks yet?

       Surround kids with enough of the characters and they'll come to believe they need them.Most of us, of course, don't buy all those items.But say no to four products out of five and your home can still get filled with these tiny items encouraging brand loyalty (品牌忠诚)

       At this time of year, parents buy licensed school supplies.With so much marketing around us, it can be tough to stop the tide.

       "One thing that helps parents'is that they can talk to other parents about, this kind of thing," Linn suggested ."If you decide you want to buck this, it helps to find other people who will do the same thing .That way, if your child says."Everyone's doing it," you can really have a sense of whether everyone is." |

From the dialogue between the author and the son, we can infer that ____-

       A.the son likes drinking yogurt a lot.

       B.buying Danimals may win a free tour

       C.the son's school encourages kids to eat yogurt

       D.Danimals in the most popular yogurt among kids.

We can learn from th^ passage that     '

       A.character bowls increase kids' appetite.

       B.character-themed wall paint is expensive

       C.household goods are becoming the target of advertisers.

       D.Linn considered character-themed products a foolish marketing strategy.

The underlined word "buck" in the last paragraph probably means _____.

       A.support        B.resist           C.advertise            D.learn

What does the passage mainly tell us ?  .

       A.Marketing is affecting kids all the time.

       B.Most kids now don't have a happy childhood,

       C.Kids like buying licensed school supplies a lot.

       D.Licensed character produce are doing great harm to kids.

NANJING, June 13,2009 (Xinhua) – China will see the longest total solar eclipse (日食) in 500 years on July 22, a scientist said Saturday.

The most important time of the total eclipse was expected to
begin from 9:00 a.m. to 9:38 a. m. (Beijing Time), said Wang
Sichao, a research fellow with the Nanjing – based Purple
Mountain Observatory under the Chinese Academy of Sciences.
“The total eclipse will l ast up to six minutes, which is the longest
one that can be seen in China in almost 500 years from 1814 to 2309,” Wang said.
He said viewers in parts of eleven provinces in China's southwestern, central-southern and eastern areas, such as Tibet, Hunan and Jiangsu, will be able to witness the total solar eclipse, while in most parts of Shanghai, viewers can see the spectacular phenomenon. For viewers in other provinces, including Beijing, they can observe a partial eclipse, he said.
A solar eclipse occurs when the moon is caught between the sun and the earth while each of them moves along their fixed orbits. In a total solar eclipse, the sun, the moon and the earth are directly aligned as the sun swings into the cone of shadow cast by the moon.
Wang said the next total solar eclipse that can be seen in China will fall on March 20 th, 2034.     "But it can only be seen remote provinces, such as Tibet and Qinghai. It cannot not be compared with the upcoming one -- in terms of duration and number of cities that can see the eclipse," he added. The last total solar eclipse visible in China took place on Aug. 1 last year. It was observed in northwest China and lasted two minutes in Yiwu County of northwestern Xinjiang Uygur Autonomous Region, the best place to see the phenomenon.
72.According to the report, the total eclipse on July the 22 nd will last         .
A.over a month                                                    B.about 38 minutes
C.about 6 minutes                                              D.less than 30 minutes
73.Viewers can possibly witness the total solar eclipse in            .
A.Liaoning                   B.Sichuan                    C.Beijing                      D.Xinjiang

As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(发电)and transmission (输送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.

The 19 th century saw land grants(政府拨地) offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the West, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns, which sprang up as railway stops and developed well, have lost their lifeblood and died.

Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now.

So trade-offs will have to be made. Some scenic spots will be sacrificed. Some species(物种) will be forced to move, or will be carefully moved to special accommodations. Deals will be struck to reduce the immediate effects.

The lasting effects of these trade-offs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways.

The money set aside in negotiated trade-offs and the institutions that control it will shape the West far beyond the immediate footprint of power plants and transmission lines. So let’s remember the effects of the railroads and the highways as we construct these new power plants in the West.

1.What was the problem caused by the construction of the railways?

A.Small towns along the railways became abandoned.

B.Land in the West was hard to manage.

C.Some railroad stops remained underused.

D.Land grants went into private hands.

2.What is the major concern in the development of alternative energy according to the last two paragraphs?

A.The use of money and power.

B.The transmission of power.

C.The conservation of solar energy.

D.The selection of an ideal place.

3.What is the author’s attitude towards building solar plants?

A.Disapproving.      B.Approving.         C.Doubtful.          D.Cautious.

4.Which is the best title for the passage?

A.How the Railways Have Affected the West

B.How the Effects of Power Plants Can Be Reduced

C.How Solar Energy Could Reshape the West

D.How the Problems of the Highways Have Been Settled
