高二英语单项填空简单题查看答案及解析
For years I wanted a flower garden. I’d spend hours thinking of different things I could plant that would look nice together.
But then we had Matthew. And Marvin. And the twins, Alisa and Alan. And then Helen. Five children. I was too busy raising them to grow a garden.
Money was tight, as well as time. Often when my children were little, one of them would want something that cost too much, and I'd have to say, “Do you see a money tree outside? Money doesn't grow on trees, you know.”
Finally, all five got through high school and college and were off on their own. I started thinking again about having a garden.
I wasn't sure, though. I mean, gardens do cost money, and after all these years I was used to living on a pretty lean, no-frills budget.
Then, one spring morning, on Mother's Day, I was working in my kitchen. Suddenly, I realized that cars were tooting their horns as they drove by. I looked out the window and there was a new tree, planted right in my yard. I thought it must be a weeping willow, because I saw things blowing around on all its branches. Then I put my glasses on — and I couldn't believe what I saw. There was a money tree in my yard!
I went outside to look. It was true! There were dollar bills, one hundred of them, taped all over that tree. Think of all the garden flowers I could buy with one hundred dollars! There was also a note attached: “IOU eight hours of digging time. Love, Marvin.”
Marvin kept his promise, too. He dug up a nice ten-by-fifteen foot bed for me. And my other children bought me tools, ornaments, a trellis (棚架), a sunflower stepping stone and gardening books.
That was three years ago. My garden's now very pretty, just like I wanted. When I go out and weed or tend my flowers, I don't seem to miss my children as much as I once did. It feels like they're right there with me.
I live up in Michigan's Upper Peninsula, where winters are long and cold, and summers are too short. But every year now, when winter sets in, I look out my window and think of the flowers I'll see next spring in my little garden. I think about what my children did for me, and I get tears in my eyes — every time.
I'm still not sure that money grows on trees. But I know love does!
1．By saying “Do you see a money tree outside .….,” the mother actually means “_______”
A．Observation is the best teacher. B．Seeing is believing.
C．The outsider sees the most of the game. D．It is not easy to gain money
2．The best title for the passage would probably be_______.
A．My flower garden B．Marvin helps to realize my dream
C．Love in Michigan D．Money grows on trees
3．The underlined word “no - frills” in the fifth paragraph is similar in meaning to_______.
A．wasteful B．tight C．absurd D．helpful
4．From the last two paragraphs we can infer that the mother is_______
A．divorced when she was young
B．not caring for her kids any longer
C．alone but not at all lonely
D．prouder with her garden than with her kids.

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
Health experts have long known that vitamin D is important for healthy bones and teeth. It may also help to protect the body against diseases such as diabetes and cancer. And now, researchers say vitamin D might help fight brain diseases called dementia (痴呆).
Dementia is a brain disease that damages thinking and memory processes, which scientists call “cognitive (认知) abilities.” Dementia is difficult to treat. Taking care of someone who has dementia is extremely demanding. And the disease is very frightening to sufferers. Chris Roberts suffers from dementia. He says the worst part of living with this disease was getting lost while driving. “The worst thing that I found was getting lost in the car, not just forgetting where I was going— I wouldn’t know where I was.” More than 47 million people around the world suffer from dementia. The World Health Organization reports that 60 percent of them live in low- and middle-income countries.
We get vitamin D from some foods like nuts, lentils (扁豆) and fatty fish. We also get vitamin D from the sun. But that is not dependable. In some parts of the world, there is not enough sunlight to provide enough vitamin D. Also, sunblock prevents the vitamin from entering the body. To add to the problem, the skin’s ability to process vitamin D weakens as a person ages.
Researchers at Rutgers University in New Jersey are exploring the relationship between vitamin D and dementia. The team recently measured vitamin D levels and cognitive ability in older people. Nutritional sciences professor Joshua Miller led the team. He said cognitive abilities differed among the study subjects. He said tests showed that about 60 percent of the group was low in vitamin D.
1.Which of the following is true about vitamin D?
A. Vitamin D can decrease people’s risk of heart diseases.
B. Vitamin D helps the body fight against cancer.
C. Vitamin D is mainly obtained from the sun.
D. The need for Vitamin D decreases as people age.
2.What does the underlined word “demanding” mean in Paragraph 2?
A. Boring but rewarding.
B. Disturbing and frightening.
C. Disgusting and stressful.
D. Hard and tiresome.
3.What does Paragraph 3 mainly talk about?
A. How vitamin D affects people’s health.
B. Where people get vitamin D.
C. Whether sunlight can produce vitamin D.
D. Why people’s age influences the production of vitamin D.
4.Where can we most probably read the passage?
A. In a travel brochure.
B. In a literature magazine.
C. In a science journal.
D. In a commercial advertisement.
