Unit 4 Astronomy the science of the stars一、閱讀理解。閱讀下列短文，從每題所給的四個選項(A、B、C和D)中，選出最佳選項。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(維基百科)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 (倡議)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【解題導(dǎo)語】本文是一篇說明文，主要講述了互聯(lián)網(wǎng)的快速發(fā)展所帶來的一些問題。1D考查細(xì)節(jié)理解。根據(jù)第二段第一句“He especially warns of false information being easily spread around the Internet”可知，他認(rèn)為虛假的信息在網(wǎng)絡(luò)上流傳是尤其嚴(yán)重的問題，故選D。2C考查推理判斷。根據(jù)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，任何人都可以輕易編輯這些傳記，因此虛假信息很容易被傳播，故選C。3B考查推理判斷。根據(jù)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，這個聯(lián)合倡議的目的是提高網(wǎng)上內(nèi)容的可信度，故選B。4C考查推理判斷。根據(jù)“Sir Tim says another major challenge will be to provide free Internet for everybody”可知，Sir Tim希望每一個人都能免費上網(wǎng)，故選C。二、單句語法填空1(2017北京高考)Every year, _ makes the most beautiful kite will win a prize in the Kite Festival.答案：whoeverwhoever “無論誰”，表泛指，在句中作主語，相當(dāng)于anyone

“(使)感到高興，(使)振作起來”。9Measures have been taken to prevent the river from _(pollute)答案：being pollutedprevent sb./sth. from doing sth. “阻止某人/某物做某事”，且本句中pollute和river存在邏輯上的被動關(guān)系，故填動名詞的被動結(jié)構(gòu)。10_(like) what you supposed, only a few people attended the party, which was disappointing.答案：Unlike根據(jù)語意可知，“并不像”你所猜測的那樣，故填Unlike，引導(dǎo)名詞性從句。三、完形填空。閱讀下列短文，從短文后各題所給的A、B、C和D四個選項中，選出可能填入空白處的最佳選項。(2018河北石家莊高三復(fù)習(xí)教學(xué)質(zhì)量檢測二)When my sister Diane began playing the
