【題目】It was when the private company successfully launched astronauts into space__________I knew it would open up more opportunities in the space industry.

A.whichB.howC.whereD.that

【答案】D

【解析】

考查強(qiáng)調(diào)句型。句意：當(dāng)私人公司成功地將宇航員送入太空時(shí)，我知道這將為航天工業(yè)開辟更多的機(jī)會(huì)。強(qiáng)調(diào)句型的結(jié)構(gòu)為It is/was + 被強(qiáng)調(diào)部分+that/who +其它。當(dāng)被強(qiáng)調(diào)內(nèi)容為人時(shí)，用who,其它全部用that。該句式的特點(diǎn)為去掉It is/was和 that，其余部分在不添加內(nèi)容的情況下，重寫后依然為完整的句子。本句中去掉It is/was和 that，重寫句子為：When the private company successfully launched astronauts into space, I knew it would open up more opportunities in the space industry.其中when…space,為時(shí)間狀語從句，其余部分為主語。句子結(jié)構(gòu)完整。所以，選項(xiàng)D符合題意。故選D。

【題目】 Growing up in an Italian-American household was, for me, pretty special. My mother, Gina, an immigrant from Italy, held on to so many of her family's traditions that at times, regardless of the fact that I was living in American, our home felt like in Italy.

To this day, my mother only speaks to me in Italian. She may speak in some English terms and expressions from time to time, but our conversations are, for the most part, in her mother tongue. And most of those conversations are about food. For us, food —Italian food is an important part of our lives. The food my mother prepared for me and my sister as children is the same food my grandmother created in her small farm kitchen high up in the mountains.

One of my family's dishes of heritage I made sure to learn and perfect is my mother's arancini di riso (Italian rice balls). Arancini, in Italian, means little oranges. After you roll some leftover rice into a small ball, place a piece of mozzarella (馬蘇里拉奶酪 ) in the center, then bread that and fry it, the golden outside resembles one of our favorite fruits. For my family, it also showcased my mother' s ability to always find a delicious way to never let anything go to waste: Last night's good rice was repurposed into this perfect mid-day snack or dinner appetizer.

So, when I take a perfect little arancini out of the hot oil and crack it open, I am immediately transported back to my childhood: I am a little girl getting off the bus and running through the back door to the smell of last night's rice transformed into sticky, delicate goodness. This small snack symbolizes so many important elements in my life: my mother' s waste-not philosophy, her ability to take a few simple ingredients and transform them, and finally, the way she carried her mother' s recipes to the U. S. in her mind and heart so she could, years later, teach me about my heritage through food.

Eating arancini, and all the other recipes my mother continued to make here in the U. S. after leaving Italy, allowed her to teach me who I am, where I come from, and why I should be proud of it all.

【1】What makes the author's home feel like in Italy?

A.Fruit and snacks.

B.Neighbors and friends.

C.Names and holidays.

D.Food and language.

【2】Why does the author make sure to learn and perfect arancini di riso?

A.It saves valuable food from going to waste.

B.It reminds the author of her days at school.

C.It plays a major role in continuing family tradition.

D.It showcases the cooking skills of the author's mother.

【3】What does the underlined word "goodness" in paragraph 4 refer to?

A.Arancini di riso.

B.Mother' s kindness.

C.The Italian language.

D.Amazing cooking skills.

【4】What is the text mainly about?

A.Why learning to cook is important for a mother.

C.How childhood experiences change one's life.

D.Why mothers are important in children's education.

【題目】 Would you leave a six-figure job to feed the homeless? This 27-year-old did. Robert Lee’s idea is seemingly simple: Get restaurants to make better use of their leftovers (剩飯菜).

When in primary school, Robert Lee would stare in disbelief at his classmates throwing away half-eaten sandwiches after lunch. His immigrant parents had taught him and his older brother not to waste food. “They said it was a bad habit,” says Robert, 27.

While studying finance and accounting at New York University, Robert remembered this lesson and joined Two Birds One Stone, a food-rescue club on campus that delivered, five days a week, uneaten pasta, vegetables, and other leftovers from the dining hall to nearby homeless shelters. In July 2013, with the $1,000 prize won in the a college entrepreneurship (創(chuàng)業(yè)) contest, Robert and fellow club member Louisa Chen founded Rescuing Leftover Cuisine (RLC). In just the first few weeks, Robert’s team delivered a donation of food to feed 20 people in line at a New York City homeless shelter that had run out of food.

As an analyst at J.P. Morgan, Robert devoted his spare time to creating a network of New York City restaurants that agreed to donate food, and he enlisted (招募) volunteers to make food deliveries to homeless shelters. Two years after being founded, RLC had already distributed more than 250,000 pounds of food.

Only a year into his finance job, Robert gave up his six-figure salary to focus on RLC. “I compared one hour of impact at J.P. Morgan to one hour at RLC, and the difference was just tremendous,” he says. The organization now reaches 16 cities around the country.

“One shelter told us that our donations allow them to provide entire dinners for more than 300 people, three nights a week,” Robert says. “Things like that make me glad I quit my job.”

【1】What did Lee do to help the homeless?

A.He worked with with other countries.

B.He built up a network of supermarkets.

C.He employed volunteers to deliver goods.

D.He co-founded Rescuing Leftover Cuisine.

【2】What does the underlined word “tremendous” in Paragraph 5 mean?

A.Slight.B.Huge.

C.Basic.D.Delicate.

【3】What can we learn from Lee’s words in the last two paragraphs?

A.Being a volunteer is of great benefit.

B.People should follow in his footsteps.

C.Everyone can make their contributions,

D.It’s worthwhile sacrificing his well-paid job.

【4】Which of the following can best describe Lee?

A.Devoted.B.Hardworking.

C.Patient.D.Optimistic.

【題目】 It's tough to see or hear of a friend in crisis. One idea to keep in mind is that it is healthy for the distressed person to feel what he or she feels in the moment. When a person in crisis feels understood, he or she feels less alone and connected to the person who understands.

A person who experiences empathy(同理心)from a friend who can “go there”for a few minutes in order to authentically understand while still maintaining a strong and supportive attitude may be relieving and healing. While a friend is telling you about the circumstance, the first and most important step is to listen for feelings, not ways to solve the problem.

For example, a friend is terribly upset because her husband is threatening to leave her. After fully honoring the feelings, it is important to ask the friend what would help. Maybe it is a good cry and some ice cream. Perhaps it's a glass of wine and a walk. Everyone has different ways of dealing. Be respectful and ask the friend what she needs or wants, not what you prescribe.

Take a second example, say a close friend is being misrepresented by other friends. The friends are gossiping about her. During a conversation with her, listen for feelings. Honor her hurt and shock. The same equation is useful with a partner.

Helping a friend or partner in crisis not only helps the person, but creates closeness and trust in the relationship, making opening up in the probable future. In addition, the person who is empathizing feels positive because he or she was able to help. When a person is truly able to comfort and reassure a loved one, he or she feels vital and useful, strengthening the relationship.

【1】What should we do first when we know a friend is in crisis？

A.Keep away from him/her.

B.Buy him/her a glass of wine.

C.Understand how he/she feels.

D.Show him/her ways to solve the problem.

【2】What does the underlined word “it” in paragraph 3 refer to？

A.A way to solve the crisis.B.A way to relieve a bad mood.

C.A way to listen for feelings.D.A way to honor the feelings.

【3】How does the author prove his/her idea？

A.By listing data.B.By quoting sayings.

C.By giving examples.D.By conducting surveys.

【4】What does the text mainly talk about？

A.How to keep a loved one.B.How to make new friends.

C.How to work with your partner.D.How to help a friend in trouble.

Dear Mike,

How is everything going with you? Hearing that you have a plan to learn Chinese, I’m writing to recommend a university that you can have a fruitful learning experience. My recommendation is Peking University, a well-known university suitable for language learning in China.

The reasons account for my recommendation are as follows. To begin with, being a first-class university with the best equipments and the finest teachers, Peking University is capable of offering professional guide and systematic training to you to master Chinese. That I think will impress you must be the resources you can have access during the whole process. Furthermore, locating in Beijing, which is the capital of China, this university has had profound historical culture. Thus, not only can we get to know those who speak standard Mandarin, but you will experience the power of Chinese culture.

All in all, I really hope you can pay a visit to Beijing. I’ll wait for you here and offer help wherever you need.

Yours sincerely,

Jane
