I would like to talk to you about space vegetables, and to show you that space vegetables are healthy and good for you.
Space vegetables are grown from seeds that have been taken to and brought back from outer space. The seeds are affected by the radiation(輻射) and low gravity in outer space. When they are brought back to Earth, these seeds produce vegetables that are bigger, healthier and more nutritious(有營養(yǎng)的) than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could give us cancer as a result of their exposure(暴露) to radiation in space. People should not be scared, as space vegetables are actually perfectly healthy.
Here are some facts that you should know about space vegetables:
Space vegetables are grown from seeds that are carefully selected. When seeds are brought back from space, they are tested to make sure that the vegetables they grow will be safe to eat. There are no traces(痕跡) of radiation after testing.
Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes. Another popular space vegetable is the peppers. Space peppers contain 20 percent more vitamin C than normal peppers.
After modified(轉(zhuǎn)基因) foods came onto the market, people worried that they were eating unknown things. For example, if nut genes are put inside potatoes, people allergic(過敏的) to nuts might get very sick from eating these potatoes because they do not know they are also eating nuts. Unlike genetically modified foods, space vegetables have not been genetically changed. This means that no new genes are put into the vegetables. Therefore, they won’t damage your health.

Today wasn’t a very good day for me. I usually get up at six o’clock, but this morning I didn’t get up         seven o’clock. I got dressed quickly and ate breakfast. It was so          that I ran all the way to the bus stop. Unfortunately, on the way I         down. My books and homework fell into the street. Papers went everywhere. At the bus stop, I waited and waited while lots of full         went by. I was so upset. At last one came but it was also full, and it went right past. But then it stopped a few yards away and someone        off. I ran wildly down the road and got the only spare seat.
At noon, I was very hungry, but I didn’t have         to buy lunch. My lunch money was at home on my desk. Then in math class, the teacher asked for my homework. I looked in my schoolbag, but my homework wasn’t there. Maybe I had lost         when fell down. The teacher punished me         making me clean the classroom after class.
My goodness, I finished        at last. When I put my things in my schoolbag and got ready to go home, I        my homework right at the bottom.

Sir Run Run Shaw, one of the pioneers (先鋒)of the 20th century Chinese film industry, passed away at his home in Hong Kong at the age of 107.

Shaw was born in Ningbo, Zhejiang, China and raised in main land China, but received his education in American-run schools.   At the age of 19, during his summer vacation, he followed his third elder brother Run Me Shaw to Singapore to start a film market and establish Shaw Organization. Following that, he developed a deep interest in the movie business. He and his brother founded the South Seas Film studio in 1930, which later became Shaw Studios. In 1967, he set up TVB (Television Broadcasts Ltd.) in Hong Kong, growing it into a multi-billion dollar TV empire(帝國) ,  one of the top 5 television producers in the world today .
In fact, the legendary man was regarded as “the most familiar stranger” by many Chinese. We know him through his donations to thousands of projects around the country, including the most famous one, “Shaw Building.”
“The ‘Shaw building’was a mark carved on our school days,” said Ma Nini, a 30-year-old editor who graduated from a university in the northeast China city of Harbin.
“No matter whether a library or a science hall, the ‘Shaw building' was always the most advanced and well-equipped one on campus,” said Ma.
Shaw was enthusiastic for charity and donated more than 10 billion HK dollars (about 1.29 billion U.S. dollars), with a large sum went to the support of education in China's mainland. Since 1985, Shaw donated 4.5 billion HK dollars for over 6,000 projects on the Chinese mainland -- over eighty percent of them related to education. In 1988, Shaw donated about 20 million yuan to build the village's Shaw Center, which includes a kindergarten, senior center. They are still in use now.
“I always go to the Shaw building on my campus to study. We never met before, but I am so grateful to the old man," said a college student surnamed Li from Tsinghua University who rushed to the village from the Ningbo Airport.
As Li paid his respects to the “most familiar stranger," he said that he would keep in mind a quote from Shaw: “Coming from people, my wealth(財富) should benefit (有益于)the people."

小題2:根據(jù)短文內(nèi)容完成句子填空(每空限填一個單詞)。

閱讀下面短文,根據(jù)所給語境,按要求完成下列各題。
A man came home from work late, tired, to find his 5-year-old son waiting for him at the door.
“Daddy, how much money do you make an hour?”
“If you must know, I make $20 an hour,”
“Oh,” the little boy replied, with his head down. He thought for a moment, looked up and said, “Daddy, could you lend me $10?”
The father was furious, “If you asked for the money to buy a toy or some other rubbish, then go straight to your room and think about why you are being so selfish(自私的)!”
The little boy quietly went to his room and shut the door. After about an hour or so, the father calmed(平靜)down, and started to think, “Maybe he really needs to buy something and he didn’t really ask for money very often.” So he went to the little boy’s room.
“Sorry! Maybe I was too hard on you just now.” said the man, “Here’s $10.”
“Oh, thank you, Daddy!” he said happily. Then, the boy took out some coins. When the father found that the boy already had money, he got angry again.
“Why do you want more money since you already have some?” the father shouted angrily.
“Because I didn’t have enough, but now I do.” the little boy replied, “Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you.”
小題1:判斷正(T)誤(F)
The boy’s father works very late, so he doesn’t often eats dinner with his son. (    )

The boy wanted to buy ______ with twenty dollars.
