人教高考英语一轮练习题选修7U3含答案.docx

2019年人教高考英语一轮练习题：选修7U3含答案 一、阅读理解The first potatoes were grown by the Incas of South America, more than 400 years ago. Their descendants(后代) in Ecuador and Chile continue to grow the vegetable as high as 14，000 feet up in the Andes Mountains. (That’s higher than any other food will grow.) Early Spanish and English explorers shipped potatoes to Europe, and they found their way to North America in the early 1600s.People eat potatoes in many ways—baked, mashed, and roasted, to name just three. However, in the United States most potatoes are eaten in the form of French fries. One fast­food chain alone sells more than $1 billion worth of fries each year. No wonder, then, that the company pays particular attention to the way its fries are prepared.Before any fry makes it to the people who eat at these popular restaurants，it must pass many separate tests. Fail any one of these tests and the potato is rejected. To start with, only Russet Burbank potatoes are used. These Idaho potatoes have less water content than other kinds, which can have as much as 80 percent water. Once cut into “shoestrings” shapes，the potatoes are partly fried in a secret blend of oils, sprayed with liquid sugar to brown them, steam dried at high heat, then flash frozen for shipment to individual restaurants.Before shipping，every shoestring is measured. Forty percent of a batch must be between two and three inches long. Another 40 percent has to be over three inches. What about the 20 percent that are left in the batch? Well, a few short fries in a bag are okay，it seems.So，now that you realize the enormous size and value of the potato crop, you can understand why most people agree that this part of the food industry is no “small potatoes”．【解题导语】　本文介绍了土豆被引进美国的历史及炸薯条在美国食物产业中举足轻重的地位。
