The winter holiday is coming. My classmates and I are talking about how to do during the holiday. We can chose between staying at home and take a trip.

It feels like every time my mother and I start to have a conversation, it turns into an argument. We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War III. She will talk about my lack(缺乏) of a bright future because I don’t plan to be a doctor. And much to her disappointment, I don’t want to do any job related to science, either. In fact, when I was pushed to say that I planned to major(主修) in English and communications, she nearly had a heart attack.

“Why can’t you be like my co-worker’s son?” she bemoans all the time. Her co-worker’s son received a four-year scholarship and is now earning 70,000 dollars a year as an engineer. I don’t know what to answer except that I simply can’t be like Mr. Perfect as I’ve called the unnamed co-worker’s son. I can’t be like him. I’m the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame (名聲) or salary.

I understand why my mother is worried about my future major. I’ve seen my mother struggle to raise me on her small salary and work long hours. She leaves the house around 6:30 am and usually comes home around 5:00 pm or even 6:00 pm. However, I want her to know that by becoming a doctor, it doesn’t mean I’ll be successful. I’d rather follow my dreams and create my own future.

1.Which of the following topics do the writer and his mother often talk about?

A. The writer’s studies. B. The writer’s future job

A. doesn’t want the writer to major in English

B. doesn’t think the writer should be a doctor

C. gets along very well with the writer

D. doesn’t think working in the science field is a good idea

A. He wants to be like his mother’s co-worker’s son.

Calvin Gillian didn’t believe that Norway was the place for an adventurous holiday. However, some friends told him to go there and he loved it.

“I’m an extreme-sports maniac. I’ve traveled to many different countries, but I didn’t expect Norway to be a good place for an extreme holiday. Tourists usually visit Norway because of its old Viking history or to go fishing and boating in the famous fjords(峽灣) to enjoy a relaxing holiday, or to go climbing to enjoy the beauty of nature. But I didn’t go for fishing; I wanted adventure.

“Skiing is the best thing you can do in Norway. Svartisen, the Black Ice glacier(冰川), is wonderful. The ice is not the usual white but a deep blue color, like the sea. However, you have to wear special clothes, because skiing on a million-year-old glacier can be very dangerous.”

“Then, there is Hunderfossen Family Park for Toll Park. You can go water skiing and ice skating. It is certainly a beautiful place but it is more expensive than visiting other parts of Norway.

“I also visited the Homenkollen Ski Jump in Oslo. The view from the top of the ski jump was wonderful and the the ski museum was very interesting. I wanted to try a jump but unfortunately, it’s only for professional ski-jumpers. Anyway, I was very tired and I needed a break, so I went back to my hotel and got some sleep.

“Next year, I am going to take my girlfriend to Norway, too. She is having her holiday in Australia now and she wants to have a different type of adventure for next year.”

1.How did Calvin Gillian feel about his trip?

A. Bored B. Relaxed

C. Satisfied D. Disappointed

2.The underlined word “maniac”(in para.2) refers to someone who___.

A. has a strong interest in something

B. has a bad opinion of something

C. expects things to be successful

D. likes to compete with others

3.What did Calvin Gillian do in Norway?

A. Ski-jumping B. Climbing

C. Fishing D. Skiing

4.What’s the best title for the text?

A. Calvin Gillian’s Holiday Countries B. Travel in Different Countries

C. Historical Places in Norway D. A Norwegian Adventure

科目:高中英語 來源:內蒙古2017屆高三上學期第一次月考英語試卷 題型:閱讀理解

For many years, I was convinced that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts and rejections with it.

Many weight-conscious people also mistakenly believe that changing our bodies will fix everything. Perhaps our mistake is believing that being thin equals being loved, being special, and being cherished. We fantasize (幻想) about what it will be like when we reach the long-awaited goal .We work very hard to realize this dream. Then, at last, we find ourselves there.

But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self-worth, and, of course, love.

It took me a long time to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us strive hard to change our body, but in vain. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes towards ourselves, the whole world changes.

1.The passage tries to stress the importance of ____________.

A. body size B. different beauty standards

C. culture difference D. attitudes towards life

2.What does the word “everything” in paragraph 2 mean?

A. The whole world B. All the problems.

C. All the properties.D. The absolute truth.

3.What can be inferred about the author?

A. The author is a Samoan.

B. The author succeeded in losing weight.

C. The author probably got wounded in wars or accidents.

D. The author has been troubled by her/his weight.

4.According to the author , what is the common view of those who have lost some weight first and gained it back later ?

A. They feel optimistic about future plans on weight control.

B. They are indifferent to the regained weight.

C. The feel angry about the regained weight.

D. They think they should give up their future plans on weight control.
