广安市2017高考英语阅读理解一轮系列训练（4）
阅读理解。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。
Recognized as the largest desert in the world, the Sahara runs across North Africa, Covering over 3 million square miles from the Atlantic Coast to the Nile River Valley. Except for an occasional oasis(绿洲), this vast land is mainly made up of sand, stones, and worn out mountains. The burning sun causes daytime temperatures to rise to 70 degrees in the shade, and days without rain commonly last for years.
Paintings found on the walls of caves in the Sahara Desert suggest that a few thousand years ago, large quantities of plants grew there and covered the desert floor. Many curious and unusual insects, birds and animals got enough food that allowed them to grow and reproduce. At that time, huge river systems and many oases supported growing communities(社团，社区) where a large number of people lived.
Research scientists believe that the land became a desert for several reasons. For centuries people there have wandered from place to place in search of food, water and grazing(吃草)land for their animals. These people have always considered the number of animals they have as a sign of wealth. It is considered more important to have 100 sick and starving animals than 15 healthy ones. The large herds (群)have been allowed to go freely and graze on desert plants and grass. Over time, large sections of land have been left uncovered. In addition to allowing overgrazing, these people cut down whatever trees they could find and used them for firewood. The sand was unable to hold on to the great heat of the day, so nightting temperatures often drop below freezing and nothing was left to hold the soil together.
Scientists have been studying different ways to bring back the green desert. Through research and experiments, they hope to be able to produce plants that will once again support the life there. Huge holes filled with much water lie under the desert surface. Scientists believe this rainwater simply flew down through the sand over hundreds of years and collected in the big, rocky holding tanks. By making use of the sun’s power, scientists in the Sahara have made experiments in which they got huge amount of electricity. This electricity was then used to operate drilling machines and pumps to pull the rainwater from the underground tanks. By drilling the hole one mile deep into the floor of the desert, one machine was able to recover more than 80 gallons of ice—cold water each second, or 288,000 gallons per hour.
Scientists have had some success turning this wasteland into useful farmland. Today the desert is dotted with huge wheat fields watered by a system of pipes that carry water from the underground tanks. Farmers have also learnt that plants grow better if seeds are planted next to stones. Studies show that stones provide protection from the sun, allowing seeds to grow in a shady and cool environment. In addition to that, greenhouses have been built to protect plants from the sunshine so that less water is needed. Another idea is to grow plants that can live on a diet of salt water, since the ocean is so near to the desert.
1. What will probably happen if the local people continue their customs and traditions?
A. The desert will continue to be enlarged.
B. Tourists will begin traveling to North Africa.
C. More oases will begin to appear across the desert.
D. The number of healthy animals will become larger.
2. Which of the flowing statements is a fact presented in the passage?
A. The desert is rich in beautiful color and scenery.
B. Camels can go for days without drinking any water.
C. The Sahara will one day become a beautiful garden.
D. Large river systems once supported many communities.
3. The author of the passage provides evidences (证据)that scientists are
A. pleased by the progress but do not have the money to continue
B. discouraged by the poor results of their experiments
C. hopeful about the chances of life coming back to the desert
D. troubled by the lack of water found underground
4. Which of the following is the best summary of this passage?
A. Drilling machines help to water the desert floor and make plants and animals alive.
B．Scientists have been able to turn this large wasteland into a successful farming community.
C. So much soil has become sand that the desert will never be able to support life as it once did.
D. The desert no longer supports plenty of life, but researchers hope to change it with new scientific techniques.
1、答案解析：答案为A。本题为推理题。结合前三段可知，撒哈拉沙漠原本是绿洲，后由于人类过度放牧（overgrazing）、滥砍乱伐（these people cut down whatever trees they could find ）导致了沙漠的形成和扩大，因此可以推断，如果当地人继续沿袭他们的老传统，会导致沙漠继续扩大。故答案为A。
2、答案解析：答案为D。本题为推理题。考生需看清题意，要求选择与原文符合的事实。由第二段最后一句话 “At that time, huge river systems and many oases supported growing communities where a large number of people lived.”可知，答案为D。
由第一段 “Except for an occasional oasis, this vast land is mainly made up of sand, stones, and worn out mountains.”可知，A选项错误；B选项未提及；C选项也不是事实。故答案为D。
3、答案解析：答案为C。本题为推理题。由最后两段可知，科学家一直在研究让沙漠变绿洲的办法，并且已经付诸实践，取得了一定的成效，故可推断，科学家满怀希望想使撒哈拉沙漠恢复生机。故答案为C。
4、答案解析：答案为D。本题为主旨大意题。本文揭示了撒哈拉沙漠形成的原因，重点是介绍科学家依靠科学技术试图让这片沙漠变成绿洲的方法。故答案为D。

Scientists investigated why Ebola virus is so deadly when it spreads from animals to humans and then from humantohuman contact. The research team looked at the Zaire Ebola virus in an animal system to understand how it gains strength. This virus is responsible for the current outbreak in West Africa. They found that initially the animal systems were not affected by the virus, but succeeding transmission(传送) into other animals caused the virus to “hot up” and become more severe.
The team analyzed the viruses at different stages and were able to identify several changes in its genetic material that were associated with increased disease.
Professor Julian Hiscox, who led the study from the University's Institute of Infection and Global Health, explains: “The work tells us that the evolutionary goal of Ebola virus is to become more fatal.”
“We were able to show through genetic analysis which parts of the virus are involved in this process. The information we have gathered will now allow us to monitor for such changes in an outbreak as well as develop future treatment strategies.”
Professor Roger Hewson, leading the study from Public Health England, Porton Down, said: “Ebola virus is such a destructive infection to the people affected by the disease and the economy of West Africa.”
“Our understanding of Ebola virus biology is way behind that of other viruses and our cooperation shows how we can bring together our specialists' skills to close this knowledge gap.”
Professor Miles Carroll, a coauthor of the work, said: “This study has allowed the team to be at the forefront of developing methodologies to analyze patient samples recently taken by the European Mobile Laboratory from West Africa to understand disease evolution during the current outbreak.”

阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项。Regardless of the fact that getting dressed in baseball caps and T-shirts are classic American style choices; the preppy(学院风格) look is what sophisticated(高雅时髦的) British youths wear. But when it comes to the best-dressed nation, neither the US nor the UK tops CNN’s list. So which country has the best fashion sense? Take a look.
Italy
Italy is a country which lays a strong emphasis on outward appearance. Elegance is in Italian blood and most Italians would give up comfort in order to look graceful. They dress well even for simple trips to the grocery store.
Both males and females have a good understanding of style, dressing themselves up with well-groomed(讲究的) hair and a smart pair of shoes. It is no wonder that so many of the best fashion designers are Italian!
Sweden
Retail(零售) giant H & M continues to spread affordable Swedish style around the world. What has been called the “Swedish fashion miracle” actually comes from the “less is more” philosophy. The Swedes tend to adopt a practical approach to what they wear, but they don’t lack creativity.
France
The French have a chic(别致的) air about them. They appear casual and elegant without being over-dressed or under-dressed, and always seem to give off confidence in their style choices. “The laissez-faire(自由放任的) approach to fashion is something many people love — and the looks they wear are something we all want to emulate on a daily basis,” said The Huffington Post.
1. Which of the following statements is TRUE according to the text?
A. Getting dressed sophisticatedly is American style.
