题组层级快练7 Unit 2 The Olympic Games . 阅读理解(2017广州市一模)Dujiangyan is the oldest manmade water system in the world, and a wonder in the development of Chinese science. Built over 2,200 years ago in what is now Sichuan Province in Southwest China, this amazing engineering achievement is still used today to irrigate over 6,000 square kilometres of farmland, take away flood water and provide water for 50 cities in the province.In ancient times, the region in which Dujiangyan now stands suffered from regular floods caused by over flow from the Minjiang River. To help the victims of the flooding, Li Bing, the region governor, together with his son, decided to find a solution. They studied the problem and discovered that the river most often overflowed when winter snow at the top of the nearby Mount Yulei began to melt as the weather warmed.The simplest fix was to build a dam, but this would have ruined the Minjiang River. So instead Li designed a series of channels built at different levels along Mount Yulei that would take away the flood water while leaving the river flowing naturally. Better still, the extra water could be directed to the dry Chengdu Plain, making it suitable for farming.Cutting the channels through the hard rock of Mount Yulei was a remarkable accomplishment as it was done long before the invention gunpowder and explosives. Li Bing found another solution. He used a combination of fire and water to heat and cool the rocks until they cracked and could be removed. After eight years of work, the 20metrewide canals had been carved through the mountain.Once the system was finished, no more floods occurred and the people were able to live peacefully and affluently. Today, Dujiangyan is admired by scientists from around the world because of one feature. Unlike modern dams where the water is blocked with a huge wall, Dujiangyan still lets water flow through the Minjiang River naturally, enabling ecosystems and fish populations to exist in harmony.1. What are the benefits of Dujiangyan according to the first paragraph? A. Reducing flooding and watering farmland.B. Protecting the mountain and reducing flooding.C. Watering farmland and improving water quality.D. Drying the river and supplying cities with water.2. What was the main cause of the Minjiang Rivers flooding? A. Heavy rains.B. Melting snow.C. Low river banks. D. Steep mountains.3. How was Li Bing able to break through the rocks of Mount Yulei? A. By using gunpowder.B. By flooding the rocks with water.C. By applying a heating and cooling technique.D. By breaking the rocks with hammers and spades.4. Why is Dujiangyan greatly admired by scientists today? A. It preserves much of the natural river life.B. It took very little time to complete the project.C. The building techniques used were very modern.D. It has raised the living standards of the local people.答案与解析【文章大意】本文介绍了中国古代水利工程都江堰的历史以及作用、优点。1. 答案A解析细节理解题。根据第一段最后一句话可知都江堰的作用是灌溉土壤和泄洪,所以答案选A项。2. 答案B解析细节理解题。根据第二段的最后一句话得知岷江的洪水问题主要是冬天山上的积雪融化导致的,所以选B项。3. 答案C解析推理判断题。根据第四段的倒数第二句话得知李冰是用加热和制冷的方式移开石头,所以选C项。4. 答案A解析细节理解题。根据最后一段的最后一句话得知都江堰至今都受科学家所推崇是因为都江堰能让水自然地流入到岷江中,并且使生态系统和水生物和平共处,所以选A项。. 完形填空(2017安徽太湖一轮)One October morning, the sky was clear and the sun was shining.

I realized that I was being exposed _8_ a different culture where certain behavior that may be _9_(accept) in America was not here.Since the trip, I have studied German for years and learned more about the world culture. I began _10_(appreciate) new things from a different perspective and with an open mind.答案与解析【文章大意】本文主要描述了作者和父母去德国的一次旅行。1. 答案attractions解析考查名词。此处指“旅游景点”, tourist attraction为可数名词,因此处有be动词are可知,应使用名词的复数形式。2. 答案but解析考查连词。句子之间构成了转折关系,因此使用but。3. 答案was解析考查动词时态。短文描述的是过去发生的事情,因此使用一般过去时,主语 the snowwhite scenery为单数,因此答案为was。4. 答案were served解析考查动词语态。主语we和serve构成被动关系,并且短文使用的是一般过去时,因此答案为were served。5. 答案a解析考查固定搭配。a couple of“几个”。6. 答案where解析考查定语从句的引导词。先行词为 mountain peak, 在从句里面充当地点状语,因此引导定语从句使用where。7. 答案it解析考查it的用法。句子的真正宾语是位于后面的that we had to pay for grocery bags, 因此此处的宾语要用it充当形式宾语。8. 答案to解析考查固定搭配。be exposed to“接触,暴露”,故答案为to。9. 答案acceptable/accepted解析考查形容词。此处位于be动词后应使用accept的形容词形式或过去分词,因此答案为acceptable/accepted。10. 答案to appreciate/appreciating解析考查动词短语。begin to do sth/begin doing sth. 意为“开始做某事”,故答案为to appreciate/appreciating。. 短文改错 (2017广东汕头)Last Tuesday, the Students Union in our school advised that Senior Three students should do something specially for their parents on their 18th birthdays.
