【解析】

这是一篇新闻报道。安徽合肥中国科技大学的一个小组用小老鼠的试验证明了,阳光中的紫外线能在大脑中产生一种变化,使得我们变得更聪明。也就是说阳光普照的天气能让我们心情好、更聪明并且记忆力更好。

1考查介词。句意:每个人都知道太阳很重要,没有太阳世界上万物都无法生长。空格处单词位于动词后,与it一起作状语,所以填介词。“除了、没有”可翻译为without,故填without

2考查动词不定式与实义动词。句意:科学已经证明阳光普照的天气能使人们心情更好、更聪明并且记忆力更好。“帮某人做某事”翻译为help sb. do sth.,“strong(强壮的)”的动词形式为strengthen(加强、巩固),故填strengthen

3考查人称代词。句意:安徽合肥中国科技大学的一个小组发现,阳光中的紫外线能使大脑里产生一种变化,使得我们更聪明。空格处单词位于make后作宾语,所以使用人称代词的宾格形式。故填us

4考查不定冠词或不定代词。句意:据牵头这项研究的中国科学技术大学生命科学学院的熊伟教授表示,对小鼠的试验表明,适度暴露在紫外线下可以改善情绪与增强学习能力。空格处单词与professor一起作Xiong Wei 的同位语,professor为可数名词,使用的是单数形式,所以空格处可以填表示“一个”的不定冠词或不定代词,professor是以辅音音素开始的,故填a/one

5考查一般现在时的被动语态。句意:他表示,这些小鼠被暴露在紫外线中,相当于在佛罗里达夏季的正午晒2030分钟的太阳。这是一个that引导的宾语从句,从句中缺谓语。句子主语miceexpose之间是被动关系,所以使用被动语态。由says可知以及全文使用的一般现在时可知,从句部分也应用一般现在时。mice为复数形式,故填are exposed

6考查一般现在时与主谓一致。句意:暴露在紫外线中增加了血液中的一种物质,它与脑细胞产生反应促进了学习和记忆功能。这是一个定语从句,主句缺少谓语。由于全文使用的一般现在时,所以这句话也应使用一般现在时。“Exposure to UV light”表达单数意义,故填increases

7考查不定式。句意同上。根据句意,这种物质与脑细胞产生反应促进了学习和记忆功能,是一种顺其自然的结果,所以可使用不定式作目的状语。故填to promote

8考查副词。句意:熊教授说,之前的研究实际上已经发现体内这种物质会改变并对我们的健康有好处,但是这是第一次发现它会在大脑内产生变化,这个发现让这个小组的成员都很吃惊。空格处单词修饰动词found,所以使用副词形式。故填actually

9考查名词。句意同上。空格处单词位于物主代词our后,所以使用名词形式。“fit(健康的)”的名词形式为fitness,故填fitness

10考查定语从句。句意同上。这是一个非限制性定语从句内潜入了一个限制性定语从句。这个限制性定语从句的先行词为a finding,指物,并且其在从句中作主语,所以可以使用关系词whichthat。又由于这个句子中已经有一个which,故填that

【题目】阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

When an important holiday comes, I usually think of what gifts to buy or prepare for my family members. It is the act itself rather than the thing you buy that 1(matter). Either a small present, a text message or a phone call can mean a lot to the receivers. 2, I had never got anything from my son, who is a university student. Parents never forget to celebrate their children’s birthday, but their children seem to be very 3 (forget). They seldom do something in return.

Life is unpredictable, and you never know what will happen tomorrow. When my son came back during the summer vacation, my wife and I, as usual, 4 (meet) him at the station. 5arriving home, much to my surprise, my son took out a wrist watch and gave it to me, 6 (say) it was a birthday gift for me. It is a very fashionable watch, 7shows not only hours, minutes and seconds but days as well. You can imagine how surprised and excited I was at that moment.

Some people say children get too much care and love from their parents and just take them for granted. It is natural for people to have such concerns and 8(worry), but things may not turn out as badly as9(expect).

【题目】阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。续写的词数应为 150 左右。

The event that stands out in Tom's memory happened one morning when Tom was only ten years old. He was at home with his elder sister Jane. Tom was doing his homework when he heard raised voices. At first he thought nothing of it since customers in the motorcycle shop directly below their flat often became loud, but he soon realized this time it was different.

“Quick! Quick! Remove the motorcycles from the shop.” someone shouted.

Then a thick burning smell filled the air. When Tom opened the front door of their flat to investigate, a thick cloud of smoke greeted him. The motorcycle shop had caught fire and people were running and crying.

Jane, who had been playing the violin in her room, hurried to the living room. They rushed out of the door and along the corridor(走廊) through the smoke.

They were heading towards the stairway at the far end of the corridor when Jane suddenly stopped. She turned around and headed back the way they came. Tom had no idea what she was doing, but he followed her.

Jane had suddenly remembered the lady in her 70s who lived next door to them, whom they called Makcik. Jane began banging on Makcik's door, but got no answer. As the smoke thickened around them, Tom could see many of their neighbors running for safety. The thought of fear crossed his mind.

“She might have run for safety like everyone else!” Tom cried. However, Jane refused to give up. “I know Makcik's still inside.” She said she was familiar with Makcik's daily routine and was certain she would still be sleeping. She hit against the door. “Go downstairs. Go now! Go!”

Paragraph 1:

Tom noticed the flame was reaching up.

【题目】 One spring morning many years ago, I had been prospecting for gold along Coho Creek in southeastern Alaska. Suddenly, no more than 20 paces away was a huge Alaskan timber wolf-caught in a trap.

From her appearance, I guessed she had been trapped for several days. She needed my help, I thought. But if I tried to release her, she would turn aggressive to me. The wolf was clearly suffering. The trap's steel jaws had imprisoned two toes. They were swollen and lacerated, but she wouldn't lose the paw (爪子) — if freed. Yet each time I moved closer, she would make a frightening growl. If I could only win her confidence, I thought. It was her only hope.

Over the next few days, I divided my time between prospecting and trying to win the wolf's trust. I talked gently with her, throwing her some meat. Gradually, I kept edging closer — though I was careful to remain beyond the length of her trap chain.

At dusk on the fifth day, I delivered her dinner. Suddenly, I saw a slight wagging of her tail. I moved within the length of her chain. She remained sill. As a towering man, my heart was in my mouth, though. Within her reach, I wrapped my blanket around myself and slowly settled onto the cold ground. It was long before I fell asleep.

The next morning, I slowly placed my hand on the wolf's injured leg. Unexpectedly; she made no threatening move. Then I applied pressure, the trap sprang open, and the wolf pulled free.

My experience told me the wolf would vanish into the woods quickly. But cautiously, she crept toward me and sniffed my hands and arms. This went against everything I'd ever heard about timber wolves. Yet, strangely, it all seemed so natural.

1What happened to the timber wolf?

A.She was stuck in a trap.B.Her food ran out.

C.Her legs were swollen.D.She was caught in the author's trap.

2What was the only hope for the wolf to be saved?

A.Some food.B.The author's care.

C.Her trust in the author.D.Winning the author's confidence.

3Why was falling asleep difficult for the author?

A.He was too close to the wolf.B.The ground was too cold.

C.The wolf remained still.D.The wolf wagged her tail.

4How did the author feel about the outcome of the event?

A.It was frightening and surprising.B.It was unexpected but natural.

C.It was humorous and natural.D.It was terrifying but encouraging.
