【題目】Blood is important to support our lives. But for now, the only way we can get more of it is through donation. And donated blood has its own problems. First of all, certain blood types are extremely rare. Type O negative blood (O-), for example, only 【1】(exist) in 7 percent of people, according to Sunday Times. There are fewer 【2】(donate) and therefore there isn’t enough of this type of blood for everybody who needs it. In addition, donated blood comes from various people, which means that it has to 【3】 (examine) carefully for diseases such as HIV to make sure that it’s safe for transfusion(輸血).

This is__【4】 scientists all over the world have been trying to make blood in labs. And now, someone finally succeeded—Marc Turner at the Scottish National Blood Transfusion Service has produced blood fit for transfusion, reported Forbes. Different from many ____【5】 scientists, who have tried to make blood by mixing up different ingredients together, Turner chose to grow blood 【6】(direct) from human stem cells. He developed 【7】 special technique to create a chemical environment similar to that in our bone marrow (骨髓). This environment encourages stem cells to develop fully 【8】 red blood cell.

According to Turner, his artificial blood is 【9】 (likely) to contain disease viruses or produce side effects. And the best part is that 【10】 he managed to produce was type O- blood. Not only is it a rare blood type, it’s also a universal type, which means it can be transfused into any patient.

【答案】

【1】exists

【2】Donors/donators

【3】be examined

【4】why

【5】other

【6】directly

【7】a

【8】into

【9】unlikely

【10】what

【解析】

試題分析：本文講述的是人們?cè)诮邮苤委煏r(shí)需要輸入血液，所以就有了捐血的行動(dòng)，但是捐血卻存在很多問題，那這些問題都是怎么被解決的呢？

【1】考查動(dòng)詞單數(shù)。主語(yǔ)是blood,是不可數(shù)名詞所以謂語(yǔ)動(dòng)詞要用單數(shù)，故填exits

【2】考查名詞。這里指的是捐贈(zèng)人，故填donors/donators

【3】考查動(dòng)詞被動(dòng)式。主語(yǔ)是血液，血液是被檢驗(yàn)的，所以這里要用動(dòng)詞的被動(dòng)式，故填be examined

【4】考查關(guān)系詞。這一句是由why引導(dǎo)的表語(yǔ)從句，后面接的是結(jié)果；故填why

【5】考查代詞的使用。這里是指其他的科學(xué)家，故填other

【6】考查副詞的用法。這里修飾的是動(dòng)詞grow,所以要用副詞，故填directly

【7】考查不定冠詞的使用。Technique是可數(shù)名詞，所以前面要加不定冠詞；故填a

【8】考查介詞的使用。題意：把干細(xì)胞變?yōu)榧t血細(xì)胞，develop into 演變成..，，故填into

【9】考查形容詞的使用。根據(jù)題意這里想表達(dá)的是否定的意思，故unlikely

【10】考查從句的使用。這里是that引導(dǎo)的表語(yǔ)從句，但是從句的主語(yǔ)不完整，所以需要用what來引導(dǎo)一個(gè)名詞性從句做主語(yǔ)，what在這里做名詞性從句的主語(yǔ)，故填what

【題目】Christmas in the United States is traditionally a time of gift-giving and family gatherings. But small towns across the country have their own traditions.

Middleburg，a small town in the state of Virginia，is known for its horses. For more than 50 years, Middleburg has organized a yearly Christmas parade(游行). Men and women ride horses through the woods and fields．They follow hunting dogs as they search for a wild fox．But first，these hunters ride in the yearly parade, wearing their bright red hunting clothes and hats．

John Hale, a citizen of Middleburg says many city people visit his town. “We have a lot of people from an urban area that come to visit，but it involves a lot of the old traditions.” The nighttime hay ride is one such tradition．Small groups gather under the moonlight on an open wagon filled with hay. The passengers sing as farm horses pull the wagon slowly across the fields．

There are some newer traditions, too. Trey Matheu works at the nearby Salamander Resort. He says a visit to Middleburg is a chance to slow down for a day. He says Middleburg can be a calming, peaceful place without tension．

“Middleburg is an opportunity to take a step back, to take a deep breath, and understand that even though life is moving on at a very fast pace, there’s really an opportunity where you’re allowed to step off for a little bit.”

Parade organizers say more than 13,000 people attend even in below-freezing weather. But if you ask，you will hear many different reasons why people come to watch the parade：

“I come here because I’m from a small town. I like how everybody comes together.”“I live right down that street; right there. And that’s my dog.”

Middleburg looks its best at Christmastime. That may be why so many people return each year．

【1】Which of the following can be the best title for the text?

A. Middleburg Christmas parade

B. A small town known for horses

C. Christmas traditions in Middleburg

D. Newer traditions at Christmastime

【2】At Christmas, people in Middleburg usually ___________．

【題目】A little old couple walked slowly into McDonald’s on one cold winter evening. It seemed that they didn’t come to the right place with the young families and young couples eating that night.

The little old man walked right up to the cash register，I placed his order with no hesitation and then paid for their meal. The couple took a table near the back wall and started taking food off the tray. There was one hamburger，one order of French fries and one drink. The little old man unwrapped the plain hamburger and carefully cut it in half. He placed one half in front of his wife. Then he carefully counted out the French fries，divided them in two piles and neatly placed one pile in front of his wife. He took a sip at the drink and then set the cup down between them.

As the man began to eat his few bites of hamburger，the crowd began to get restless. You could tell what they were thinking，“That poor old couple. All they can afford is one meal for the two of them.”

As the man began to eat his French fries，one young man stood and came over to the old couple’s table. He politely offered to buy another meal for the old couple to eat. The old man replied that they were just fine. They were used to sharing everything.

As the little old man finished eating and was wiping his face neatly with a napkin，the young man could stand it no longer. Again he came over to their table and offered to buy some food.

After being politely refused again，he finally asked a question of the little old lady，“Ma’am，why aren’t you eating？You said that you share everything. What is it that you are waiting for?

She answered，“The teeth.”

【1】Who were eating in McDonald except the old couple that night? (No more than 8 words)

【2】What did the old man order? (No more than 12words)

【3】Why did the young man offer to buy some food for the old couple? (No more than6 words)
