高三英语单项填空中等难度题查看答案及解析

You might easily gain access to fresh fruit and vegetables, but this isn’t the case in some parts of America. The U. S. has many areas that are considered as food deserts, which are defined as parts of the country short of fresh fruit, vegetables and other healthy food, usually found in poor areas.

Food deserts are urban areas where the nearest grocery store is more than 1 mile away, and rural areas where the nearest grocery store is more than 10 miles away. According to the USDA, 19 million Americans — or 6.2% of the population — live in places that can be considered as food deserts.

The issue isn’t necessarily about the difference in cost between healthy and unhealthy foods in these areas but it’s about a lack of access to healthy choices at all. And, with the lack of healthy food choices, these areas typically have a large supply of unhealthy foods sold at fast-food companies and convenience stores.

Eating unhealthy foods can lead to overweight, which puts people at risk for all kinds of major health issues, including high blood pressure, heart disease, and some cancers.

But some people, especially those who cannot afford a car, are stuck with eating what’s readily available. In the case of food deserts, it’s usually the type of food that can lead to overweight. Studies have shown that this is likely to be a problem in low-income areas. When money is not enough, people tend to buy foods that last longer and remove food waste, which is a waste of their limited income.

Lack of access is only one part of the problem, however. The bigger issue was likely the lack of education and nutritional knowledge in these communities, which prevents people with lower incomes from understanding the benefits of healthy eating.

While overweight is a significant issue in these communities, the cost of unhealthy eating isn’t just physical. A study found that 71 billion dollars in healthcare costs due to chronic (慢性的) diseases could be saved through healthier eating.

1.What can we infer from the first two paragraphs?

A.6.2% of the Americans live in poor areas.

B.Some parts of the USA lack fresh vegetables.

C.Some people in America don’t need fresh fruit.

D.People in the food deserts buy fresh vegetables easily

2.Why can fast-food companies sell large amounts of unhealthy food in the food deserts?

A.These areas are rich in unhealthy food materials.

B.The fast food sold in the food deserts are of lower cost.

C.Healthy food choices are unavailable in these areas.

D.People in these areas prefer unhealthy food to healthy food.

3.We can learn from Paragraph 5 that the low-income people______.

A.are less likely to have overweight problems

B.are not delighted to prepare food for themselves

C.have to buy food that can be preserved longer

D.are used to eating food donated by food companies

4.What stops people from understanding healthy eating benefits in the food deserts?

A.Their high healthcare cost due to the chronic diseases.

B.Their long established eating habits.

C.The government’s lack of financial support.

D.Their lack of education and knowledge in nutrition.

B

I had never seen sand dunes（沙丘）before. If you go to the seaside in Britain, you may see some small hills of sand, but nothing very impressive. Of course, Africa is home to many beautiful “sandscapes”, but I was in China, so I went to Dunhuang.

I had spent my first day looking at the beautiful Mogao caves. Now I wanted to experience something very different.

I have been walking in Asia, Europe and America, but nothing prepared me for walking over hills of sand. Whenever I took a step up a hill, my feet would sink into the sand and move backwards. Sometimes it seemed as if I were moving in the wrong direction.

I wanted to see the sunset so I had to climb to the top of the highest sand dune. The sun was beating down upon my back as I walked slowly over the sand. Some plants had managed to survive in the dry ground but not many.

As I climbed higher, the hills of sand became steeper and my feet started to slip further backwards. I ended up with my hands and knees, crawling (爬行)upwards through the top. I just let go if I would fall the way down. But I refused to give up: inch by inch, I made my way to the top of the sand dune.

When I got there I was amazed by what I saw. The sand formed a very sharp point, just like a knife-edge. One side of the dune was bathed in sunshine, the other covered by shade. As I looked into the distance, the same pattern was repeated on all of the hilltops, and the difference between dark and light was beautiful.

As the sun began to sink, the shadows grew longer and the light became warm and orange. The wind had come to life and sand was blown against my legs as I walked along the dunes. Soon it was getting dark and I could only just make out the line of footprints that marked my journey to the top of the hill. I slowly made my way down to the bottom, my path lit by the dying sun.

65 The author probably went to climb the sand dunes __________ after he arrived at Dunhuang.

A. on the afternoon of the first day       B. on the afternoon of the second day

C. on the evening of the second day      D. on the evening of the first day

66. Which of the following statements is NOT true?

A. Africa has many beautiful sand dunes.

B. The author could see nothing but his own footprints on his way back.

C. The author had seen some kinds of sand dunes before he visited Dunhuang

D. What attracted the author most was that the sand formed a very sharp point.

67. The author got to the top of the highest hill of sand _____________.

A. on his hands and knees all the way

B. with falls to the bottom many times

C. on his hands and knees in the last leg (一段旅程)

D. with a few rests all the way

68. The author mainly wants to tell readers about_____________.

A. the beautiful sunset         B. his experience of climbing the sand hills

C. the joy of traveling in nature  D. the difficulty of climbing the sand dunes

For six hours we shot through the landscape of the Karoo desert in South Africa. Just rocks

and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I’d bought in a market in Mozambique.

Southern Africa was full of stories. And visions. We were almost drunk on sensations. The roaring of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana . And then the other things: dogs in the streets, whole families in Soweto living in one room, a kilometre from clean water.

As we drove towards the setting sun, a quietness fell over us. The road was empty -- we  hadn’t seen another car for hours. And as I drove, something caught my eye, something moving   next to me. I glanced in the mirror of the car; I glanced sideways to the right, and that was when I saw them. Next to us, by the side of the road, thirty, forty wild horses were racing the car, a cloud of dust rising behind them -- brown, muscular horses almost close enough to touch them, to   smell their hot breath. I didn’t know how long they had been there next to us.

I shouted to Dan: “Look!”, but he was in a deep sleep, his camera lying useless by his feet.   They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms   in the red landscape. When Daniel woke up an hour later I told him what had happened.

“Wild horses?” he said. “Why didn’t you wake me up?”

“I tried. But they were gone after a few seconds.”

“Are you sure you didn’t dream it?”

“You were the one who was sleeping!”

Typical, he said. “The best photos are the ones we never take.”

We checked into a dusty hotel and slept the sleep of the dead.

1. During their journey in Africa, the two travelers______.

2. What did Daniel think when he woke up and was told what had happened?

3. What is the passage mainly about?
