单元仿真检测二Unit 2Working the land满分：120分限时：100分钟Ⅰ.阅读理解AThe first settlers to come over to America needed to become good farmers in order to survive. The agricultural industry was grown greatly and now the agricultural job market can be very rewarding (值得的). Many of the new agricultural jobs these days deal with the new types of technology that are needed to produce the crops that America needs.The days of a family working their land by hand and producing a small amount of crops are over. Now many large plantations (种植场) are to harvest a larger amount of crops in a shorter period of time. If you would like to get one of these new types of jobs in the agricultural industry, then you will need to make sure that you stay on top of the new technologies.Many of these new jobs in the agricultural field have included these new technologies. Two of the new technologies that have brought many new jobs in the agricultural industry are Global Positioning System (GPS) and biotechnology. The GPS really has the ability for farmers to seed and get in their crops in the best possible way.The biotechnology field has really allowed better and safer fertilizers (肥料) to be used on crops. Biotechnology has also helped farmers to better understand what helps to make their crops better. Both of these new technologies are very interesting and offer many new opportunities. The agricultural industry still needs quite a bit of hard work to bring in a good crop, but now many people can take advantage of these improvements to make the industry a much better experience.1．What's the main idea of the passageA．New technologies have brought many new jobs to Americans.B．Farmers should try to stay on top of the new technologies.C．The agricultural industry in America could support more people.D．New technologies are widely used in new agricultural jobs.2．From Paragraph 1, we know that ________.A．people came to live in America a long time agoB．people have to be farmers in order to surviveC．technology is important for the agricultural industry D．American people are in great need of crops3．If you want to get an agricultural job, you should ________.

It is also expensive. Some organic food costs twice as much as non-organic food. Some parents and pet owners pay up to 200 percent more for organic food while some people think organic food is a waste of money.There is one main difference between organic and nonorganic food. Organic farms do not use agricultural chemicals, such as pesticides (杀虫剂). This guarantees that the products are natural.Some people think “organic”means “locally grown”.Originally this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There weren't enough organic materials. This made it difficult for many organic companies to stay in business. Today, many large companies have an organic line of products.Is organic food more nutritious (有营养的) This is part of the debate. Many farmers andconsumers (消费者) believe it is. They think agricultural chemicals cause health problems, such as cancer. Many health professionals disagree. Few studies prove that organic food prevents health problems. Health specialists worry more about bacteria. These can come into contact with organic and non-organic food. Doctors recommend washing produce very carefully.Most people agree that naturally-grown food tastes better. Is tastier food worth the extra money This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry.9．In Paragraph 3, the author points out that ________.A．most organic food is locally grown nowadaysB．organic farming once experienced a difficult periodC．organic food tastes better than non-organic foodD．organic companies find it difficult to earn money10．We can learn from the passage that health experts ________.A．believe organic food prevents health problemsB．consider organic food a waste of moneyC．don't share many consumers' viewsD．recommend eating organic food11．In many organic consumers' opinion, organic food is better for the following reasons EXCEPT ________.A．being healthier B．being more beautifulC．being tastier D．being more nutritious12．The author develops the passage mainly by ________.A．providing some examplesB．following the natural time orderC．comparing opinions from different fieldsD．showing a cause and then its effectsDOne afternoon Peter and Jim went out for a bicycle ride.

The firemen had left the burning buildings and were pouring (浇) water onto the neighboring houses, trying to stop the fire from spreading. Then the wind died down. A second pump was brought up to help, and the fire was gradually put out.“It's soon finished，”Peter said to his friend. “We must go or we shall get home late.”“Yes, come on，”agreed Jim, and with a last look at the ruins, they walked back to their bicycles.13．Seeing the fire, the boys ran to the village to ________.A．watch it B．ask for helpC．help the firemen D．warn the villagers14．The villagers were told to keep away from the fire mainly because ________.A．their help was unnecessaryB．it was spreading very rapidlyC．two burning buildings were falling downD．one of the buildings stored a lot of paint15．The firemen tried to stop the fire from spreading by ________.A．using an airplaneB．using more fire enginesC．pulling down the burning housesD．pouring water onto the neighboring housesⅡ.任务型阅读What causes a floodFloods are one of the most common disasters in the United effects can be local, impacting a neighborhood or community, or very large, affecting several states.__16__ Some floods develop slowly，sometimes over a period of flash floods can develop quickly, sometimes in just a few minutes and without any visible (看得见的) signs of floods often have a dangerous wall of roaring water and can take away most things in its path.Floods happen when a watercourse (水道)Heavy rainWhen the ground already contains a lot of water, the falling rain could not seep through water then starts flowing toward a it rains a lot in a region, all water flows toward the river, but this river can not containThawWhen spring arrives, snow and ice start to melt and the water flows toward the the river overflows and a flood happens.Ice jamIn spring, rivers thaw out and pieces of ice drift on the As a result, these pieces of ice form a kind of dam (水坝).
