A. to have played??? B. played??? C. playing??? D. to play

 

【答案】

D

【解析】

試題分析:考查不定式用法,當(dāng)不定式做定語修飾名詞的時候,如果該動作是句子主語所做,使用主動形式來表示;如果動作不是句子主語所做,就使用被動的形式。本題中的play是有主語each of us所做,所以使用不定式的主動形式表示被動的含義。句意:她告訴我們?yōu)槭裁此龔娏业馗杏X到我們每個人在讓地球成為人類居住的更好的地方方面都可以起作用。故D正確。

考點:考查不定式用法

點評:當(dāng)不定式做定語修飾名詞的時候,如果該動作是句子主語所做,使用主動形式來表示;如果動作不是句子主語所做,就使用被動的形式。

When my grandfather died, my 83-year-old grandmother, once so full of life, slowly began to fade. No longer able to manage a home of her own, she moved in with my mother, where she was visited often by other members of her large, loving family. Although she still had her good days, it was often hard to arouse her interest.

But one chilly December afternoon three years ago, my daughter Meagan, then eight, and I were visiting her, when she noticed that Meagan was carrying her favorite doll.

“I, too, had a special doll when I was a little girl,” she told a wide-eyed Meagan. “I got it one Christmas when I was about your age. I lived in an old farmhouse in Maine, with Mom, Dad and my four sisters, and the very first gift I opened that Christmas was the most beautiful doll you’d ever want to see.”

“She had an elegant, hand-painted face, and her long brown hair was pulled back with a big pink bow. Her eyes were blue, and they opened and closed. I remember she had a body of kidskin, and her arms and legs bent at the joints.”

GG’s voice dropped low, taking on an almost respectful tone. “My doll was dressed in a pretty pink gown, decorated with fine lace. … Getting such a fine doll was like a miracle for a little farm girl like me — my parents must have had to sacrifice so much to afford it. But how happy I was that morning!”

GG’s eyes filled and her voice shook with emotion as she recalled that Christmas of long ago. “I played with my doll all morning long. And then it happened. My mother called us to the dining room for Christmas dinner and I laid my new doll down gently on the hall table. But as I went to join the family at the table, I heard a loud crash.”

“I hardly had to turn around — I knew it was my precious doll. And it was. Her lace skirt had hung down from the table just enough for my baby sister to reach up and pull on it. When I ran in, there lay my beautiful doll on the floor, her face smashed into a dozen pieces. She was gone forever.”

A few years later, GG’s baby sister was also gone, she told Meagan, a victim of pneumonia(肺炎). Now the tears in her eyes spilled over — tears, I knew, not only for a lost doll and a lost sister, but for a lost time.

Silent for the rest of the visit, Meagan was no sooner in the car going home than she exclaimed, “Mom, I have a great idea! Let’s get GG a new doll for Christmas. Then she won’t cry when she thinks about it.”

My heart filled with pride as I listened to my sympathetic little daughter. But where would we find a doll to match GG’s fond memories?

Where there’s a will, as they say, there’s a way. When I told my best friends, Liz and Chris, about my problem, Liz put me in touch with a local doll-make. From a doll supply house I ordered a long brown hair and a kidskin body to copy the outfit GG had so lovingly described. Liz volunteered to put the doll together, and Chris helped me make the doll’s outfit. Meagan wrote the story of the lost doll by giving examples.

Finally our creation was finished. To our eyes it was perfect. But there was no way it could be exactly like the doll GG had loved so much and lost. Would she think it looked anything like it?

On Christmas Eve, Meagan and I carried our happily packed gift to GG, where she sat surrounded by children, parents, aunts, uncles and cousins. “It’s for you,” Meagan said, “but first you have to read the story that goes with it.”

GG no sooner got through the first page than her voice cracked and she was unable to go on, but Meagan took over where she left off. Then it was time to open her present.

I’ll never forget the look on GG’s face as she lifted the doll and held it to her chest. Once again her tears fell, but this time they were tears of joy. Holding the doll in her frail arms, she repeated over and over again, “She’s exactly like my old doll, exactly like her.” 

And perhaps she wasn’t saying that just to be kind. Perhaps however impossible it seemed, we had managed to produce a close copy of the doll she remembered. But as I watched my eight-year-old daughter and her great-grandmother examining the doll together, I thought of a likelier explanation. What GG really recognized, perhaps, was the love that inspired the gift. And love, wherever it comes from, always looks the same.

1.GG moved in with her daughter because____.

A.she wanted to live with a large family

B.she was not able to live on her own due to her weakness

C.her husband passed away

D.she thought it was the children’s obligation to take care of her

2.Why did GG become very emotional on a December afternoon?

A.Because she saw her great granddaughter’s doll.

B.Because she recalled her dead parents.

C.Because she was surrounded by her offspring.

D.Because she felt lonely during the Christmas season.

3.What can we infer from Paragraph 5? 

A.GG’s doll was important and was a symbol of many things.

B.GG showed great respect for his husband’s love.

C.GG missed the great old days she spent with her family.

D.GG was grateful for her long life.

4.What happened to GG’s baby sister?

A.She envied her sister all her life.

B.She felt guilty for breaking GG’s doll and decided to go.

C.She left home at a young age.

D.She died of some disease at a young age.

5.Why did Meagan’s mum feel proud of her daughter?

A.Because she was clever.                  B.Because she was loving.

C.Because she was sensitive.                D.Because she was imaginative.

6.The main idea of the passage is that ____.

A.treating the elderly well is moral

B.it is impossible to copy the exact doll for the elderly

C.love, the permanent rhythm of life, will always remain in the elderly’s heart

D.physical comfort from children rather than psychological care is important

Mothers can still offer comfort, even from a distance, a new study has found. The results show that simply hearing their mothers’ voice over the phone works just as well at calming the nerves of stressed children as a real-life pat on the shoulder.

The soothing(撫慰的)effect is most likely due to the release of the hormone(荷爾蒙), oxytocin(催生素), in the brain, the researchers say. This “l(fā)ove hormone” is known to quell stress and is likely to be involved in social connections, including those between a mother and a child.

Previous work has revealed that this hormone is released during physical contact with a mother. “But it’s clear from these results that a mother’s voice can have the same effect as a hug, even if she isn’t actually standing there,” said the researcher, Leslie Seltzer, a biological scientist.

Seltzer tested a group of 61 girls, aged 7 to 12, by having them make an unprepared speech and solve a series of maths problems in front of a group of strangers, sending their hearts racing and levels of cortisol—a hormone associated with stress—soaring.

Facing a challenge like that raises stress levels of a lot of people. Once stressed, a third of the girls were comforted in person by their mothers with hugs. A third of the girls watched an emotionally neutral 75-minute video. The rest were handed a telephone with their mothers on the line.

For the girls who interacted in person or over the phone with their mothers, the levels of the “l(fā)ove hormone” rose significantly, and the stress-marking hormone was washed away. This effect didn’t show up for participants who watched the video.

Seltzer is now testing the amount of oxytocin released with other communication methods—like text messaging—and hopes to see the research spread out from human subjects. “It’s not just us, of course. Lots of very social species have voices,” she said. “on the one hand, we are curious to see if this effect is unique to humans. On the other, we’re hoping researchers who study vocal communication will consider looking at oxytocin release in other animals and apply it to broader questions of social behavior and evolutionary biology.

1.Mothers’ voice over the phone can reduce children’s nerves according to the study, because           .

A.children can imagine their mothers’ hugs on the line

B.children enjoy their mothers’ voice and forget their worries

C.mothers are good at comforting their children, even on the phone

D.mothers’ voice can promote the release of the love hormone

2.The underlined word “quell” in the second paragraph probably means “         ”.

A.cause or bring

B.delay or direct

C.stop or reduce

D.develop or train

3. From the study, we know that                .

A.the level of cortisol determines how stressed a person is

B.the 61 girls were divided into two groups in the research

C.the recent study had the same results as the previous one

D.watching a video is the best way to reduce one’s stress

4.From the last paragraph, we can conclude that          .

A.text messaging has the same effect on oxytocin release as telephoning

B.the effect of a mother's voice on oxytocin in animals is still not known

C.the effect of communication on stress is unique to humans

D.the research has been applied to social behavior and evolutionary biology
