A. Red.
B. Green.

12. How does the man sound at the end of the conversation？
A. Grateful.
B. Humorous.

【答案】10. C 11. A 12. B
【解析】Text 8
W: Welcome to our program, Dr Peterson. Let's see what questions we've got for you today. Here's one: Can cats see color?
M: Sort of. In the wild, many cats hunt at night because their eyes are designed for low light. Your cat can't see bright
colors such as red and green. But it picks up more shades of blue, yellow, and grey than humans do.
W: And why do cats give dead birds to their owners?
M: When your cat drops a dead bird at your feet, she isn't bringing you a present. Most cats just drag food home because it's a safe place to eat. A cat's mom also brings home things to her children to help them practice hunting. So, a female cat without children may bring these "treats" to her owner instead. You may not like them, but at least you don't have to write her a thank-you note.

M: Oh, he's doing fairly well. It's been three weeks since he first started going, so Macy and I are pretty used to it now. You should have seen Macy cry when Ed was about to set off on the first day, though.

My name is Emily. I had been a dancer for quite a long time. I started studying ballet when I was six years old. By the time I was nine, I was dancing five days a week. When I was eighteen, I decided that I really preferred contemporary dance and that I wanted to do it professionally. So I applied successfully for the training program at the school of Toronto Dance Theatre, and moved to Toronto to attend the program. That was the period of time I enjoyed most in Toronto. I graduated on scholarship and danced professionally for ten years. But after all, those years, I found that dance was gradually becoming something that felt like more of a burden than a joy. I found myself increasingly unwilling to drag myself to dance performances, so I quit. I do miss dance, often. But it mak es me happy think that I’ll never have to go to another training session again.

New technologies and a rising interest in healthier and organic eating have had a huge impact on how farms do business. At the same time, a growing population has put more demands on farmers. They need to find ways to increase their production levels. The small family farms that used to produce most of the products have been largely replaced by factory farms. Small family farms that are still operating are struggling to keep up. Technology has made most aspects of farm life easier than it has ever been before. Bigger and more efficient equipment makes work such as plowing up fields and sowing the seeds easier. Such tasks used to take two or three times as long. These advances have allowed farmers to work faster and more efficiently than ever before. In addition to newer technology, factory farms produce more products for less money than traditional farming would require. Modern farm life, despite the introduction of new technologies, has not changed much from what has always been. Farmers still wake up early, and spend their days doing hard work. There are animals to feed, cows to be milked, and fields to be plowed. Farm still requires a lot of hard work and sacrifice. The main change in modern farm life is still in the way farms are run. It is common for even small farms to have several hired workers and even an animal manager. Family-run farms are becoming rarer. Factory farms, with other larger farm corporations, are becoming the norm. Although there are still many traditional family farms, they are quickly dying as modern practices change farm life forever. 1.Factory farms now produce most of the products A.True B. False C. Not given 2.Farmers prefer to grow healthy and organic food. A.True B. False C. Not given

2018年4月全国高等教育自学考试试题 英语（二）试卷 （课程代码00015） 一、阅读判断1’*10=10’ Life on the Farm Life on a farm is always changing. New technologies and a rising interest in healthier and organic eating have had a huge impact on how farms do business. At the same time, a growing population has put more demands on farmers. They need to find ways to increase their production levels. The small family farms that used to produce most of the products have been largely replaced by factory farms. Small family farms that are still operating are struggling to keep up. Technology has made most aspects of farms life easier than it has ever been before. Bigger and more efficient equipment makes work such as plowing up fields and sowing the seeds easier. Such tasks used to take two or three times as long. These advances have allowed farmers to work faster and more efficiently than ever before. In addition to newer technology, factory farms produce more products for less money than traditional farming would require. Modern farm life, despite the introduction of new technologies, has not changed much from what it has always been. Farmers still wake up early, and spend their days doing hard work. There are still animals to feed, cows to be milked, and fields to be plowed. Farm life still requires a lot of hard work and sacrifice. The main change in modern farm life is in the way farms are run. It is common for even small farms to have several hired workers and even an animal manager. Family-run farms are becoming rarer. Factory farms, with other larger farm corporations, are becoming the norm. Although there are still many traditional family farms, they are quickly dying as modern practices change farm life forever. 1. Factory farms now produce most of the products. A. True B. False C. Not Given 2. Farmers prefer to grow healthy and organic food. A. True B. False C. Not Given 3. Small family farms find it hard to survive. A. True B. False C. Not Given 4. Plowing and sowing by machines are advances in modern farming. A. True B. False C. Not Given 5. Modern farm products cost more than those from traditional farming. A. True B. False C. Not Given 6. Most farmers cannot afford new machines. A. True B. False C. Not Given 7. Modern farmers do not have to work hard.
