Unit 4 Astronomy the science of the stars一、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。One of the main creators of the World Wide Web，Sir Tim BernersLee has warned that the fast growth of the Internet is also creating serious problems.He especially warns of false information being easily spread around the Internet，“A great danger is that it bees a place where untruths start to spread more than truths，or it bees a place which bees increasingly unfair in some way.”In particular he mentions the phenomena of blogging.Blogging enables friends and contacts to easily spread information.However he argues that people may too easily trust information mentioned in a blog.This inaccurate information can then easily bee an accepted truth on the Internet.He suggests that the most important development of the Internet will be in creating ways of allowing people to check the correctness of information by providing original sources.Sir Tim admits that this is an important challenge.Its interesting to note that Wikipedia(维基百科)has had to take steps to prevent false information from being added to the biographies of living people.Its easy for anybody to edit the open source.However，some people have pointed out that it has been used to spread false materials.In seeking to raise standards，Wikipedia has sought to stop the false materials.At the same time there is a growing view that the Internet has had a great effect on the way millions of people work.The last two years have seen a big growth in the use of the Internet.There appears no slowdown in the growth of the Internet with increasing access in the developing countries.Sir Tim says another major challenge will be to provide free Internet for everybody.Sir Tim has recently launched a new joint initiative (倡议)between the University of Southampton and the Massachusetts Institute of Technology to create the first degree in Web science.The two schools hope to raise the standards of web content.1What is the especially serious problem that Sir Tim refers to?AThe growth of the Internet is too fast.BThe Internet has a side effect on young children.CThe Internet panies pete against each other in an unfair way.DThe false information spreads rapidly on the Internet.2What causes the biographies to have false information?AThe Internet users refuses other users to correct them.BWikipedia doesnt take any steps.CAnybody can easily edit the biographies.DWikipedia attempts to publish false materials.3According to the last paragraph，the purpose of the joint initiative is to _.Aprovide free Internet access to the poor countriesBimprove the reliability of online contentCcreate the first degree in science and technologyDenlarge the use of the Internet4We can infer from the text that _.ASir Tim has built two schools recentlyBthe Internet is harmful to the peoples healthCSir Tim hopes everyone can use the Internet for freeDthe Internet develops slowly in the developing countries【解题导语】本文是一篇说明文，主要讲述了互联网的快速发展所带来的一些问题。1D考查细节理解。根据第二段第一句“He especially warns of false information being easily spread around the Internet”可知，他认为虚假的信息在网络上流传是尤其严重的问题，故选D。2C考查推理判断。根据第三段中的“Its easy for anybody to edit the open source.However, some people have pointed out that it has been used to spread false materials”可知，任何人都可以轻易编辑这些传记，因此虚假信息很容易被传播，故选C。3B考查推理判断。根据最后一段中的“the University of Southampton and the Massachusetts Institute of Technology to create the first degree in Web science.The two schools hope to raise the standards of web content”可知，这个联合倡议的目的是提高网上内容的可信度，故选B。4C考查推理判断。根据“Sir Tim says another major challenge will be to provide free Internet for everybody”可知，Sir Tim希望每一个人都能免费上网，故选C。二、单句语法填空1(2017北京高考)Every year, _ makes
