第二单元过关检测(时间:90分钟满分:120分).阅读理解(共12小题;每小题2.5分,满分30分)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。AThe United States Department of Agriculture has a program called Wildlife Services.Its job is to help protect agriculture and other resources from threats and damage by wildlife.Often that means helping farmers deal with unwelcome visitors.This organization has experts from different fields and it has set up thousands of inquiry agencies all over the country where farmers can explain their difficulty and get practical help.One example from Wildlife Services of its work involved a farmer in Washington State,in the Pacific Northwest.Several years ago,thousands of Canada geese landed on his fields.The geese began to eat his carrot crop.Biologists from the program suggested that the farmer use noise-making devices and other measures to scare the large birds away.These efforts apparently succeeded,which made the farmer quite happy.Wildlife Services also has a livestock(牲畜)protection program.The program just offers suggestions to keep those unwelcome visitors away instead of killing them.Experts suggest providing secure shelter for chickens,sheep and other animals that could be attacked.They also suggest using lights above places where animals are kept.And they advise people who see coyotes around their property to chase them away by shouting,making loud noises or throwing rocks.For home gardeners,a two-meter fence might help keep out deer.To keep out rabbits,a wire fence has to be only about a half-meter high.It should extend fifteen centimeters underground to keep rabbits from digging under it.If snakes are a problem,remove dead trees and cut high grass to destroy their hiding places.And to protect livestock,consider using guard animals such as dogs and donkeys,which are very effective.Due to its effective work,ever since the Wildlife Services was started,it has been well received by farmers all over the States and neighboring countries such as Canada and Mexico.1.The underlined phrase “unwelcome visitors” in the first paragraph refers to .A.animals that attack the farmersB.people who dont care about wildlifeC.animals that do harm to the crops or livestockD.people who pollute the environment of the farms提示:考查名词指代。由第一段第二句话“Its job is to help protect agriculture and other resources from threats and damage by wildlife.”可知,Wildlife Services 是帮助农民驱走危害农作物和家畜的动物的一个组织。答案:C2.It can be inferred from the second paragraph that .A.the farmer didnt have a gun to kill those Canada geeseB.Wildlife Services involves some biologists in its groupC.the carrot crop was eaten up by the Canada geeseD.the farmers like to eat Canada geese very much提示:考查推理判断。由第二段中的“Biologists from the program suggested that the farmer use noise-making devices and other measures to scare the large birds away.”可知,B项正确。答案:B3.What is mainly discussed in the last paragraph?A.Ways to protect livestock.B.Ways to deal with coyotes.C.How to protect crops.D.How to find wildlife.提示:考查段落大意。第三段首句“Wildlife Services also has a livestock(牲畜)protection program.”是主题句,下面的内容都是围绕这一主题进行的。答案:A4.How is the program getting along?A.It remains to be improved.B.It is very popular among experts.C.It is well received by the local government.D.Farmers in the U.S.,Canada and Mexico think it effective.提示:考查细节理解。由文章最后一句“Due to its effective work,ever since the Wildlife Services was started,it has been well received by farmers all over the States and neighboring countries such as Canada and Mexico.”可知答案。答案:DBEvery time you go shopping,the vegetables and fruit look so tempting that you wish you could buy all of them.Some people are lucky and can grow the fruit and vegetables in the gardens that they have.While getting fresh vegetables,they can also achieve great cost cutting.Mushrooms are expensive and can also go bad very quickly.Mushrooms can also be grown easily in a dark environment.In fact its better than growing other vegetables since you really dont need an outdoor space.A special type of soil that is good for growing mushrooms is easily available.Actually mushrooms arent even vegetables;they are fungi(菌类)and for this reason,you dont even require sunlight to grow them.Well,how does one go about growing mushrooms?You could always Google “growing mushrooms” and you will find a number of mushroom growing kits(工具)available online that area effective and not very expensive either.Mushrooms can be added to any dish that you cook.Simply use them in pizzas,salads and anything that you pretty much fancy.Grow mushrooms in your own house and use them whenever you want.Fresh mushrooms are tastier than the ones that are stored in your refrigerator.If you have had a really good crop of mushrooms,then you can even store them.Ideally you should use the white variety of the mushrooms.Simply pick them,slice them and put them on a cookie sheet in a freezer.When they are frozen,just put them in a zip lock and you
