Tim Berners?Lee is the man who wrote the software programme that led to the foundation of the World Wide Web. Britain played an important part in developing the first generation of computers. The parents of Tim Berners?Lee both worked on one of the earliest commercial computers and talked about their work at home. As a child he would build models of computers from packaging material. After graduating from Oxford University he went on to the real thing. In the 1980's, scientists were already using a primitive version (原始版本) of e?mail. While working at a laboratory in Switzerland Tim Berners?Lee wrote a programme which let him store these messages. In 1990 he wrote the HTTP (服务程序所用的协议) and HTML (超文本链接标示语言) programmes which form the basis of the World Wide Web.

The next year his programmes were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used his codes to work with different operating systems. New things like web browsers (浏览器) and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100, 000.

In 1994 Tim Berners?Lee formed the newly formed World Wide Web Consortium (协会) or W3C.More than 200 leading companies and laboratories are represented (代表) by W3C.Together they make sure that everyone can participate equally on the Web.

1．The main idea of this passage is ________．

A．when the Internet appeared

B．how Tim Berners?Lee formed W3C

C．why computers develop so rapidly

D．how the World Wide Web started

2．Scientists began to use e?mail ________．

A．in 1980 B．after the 1980's

C．in the 1980's D．in the 1960's

3．Which of the following is NOT true?

A．The number of web pages rose very rapidly in the 1990's.

B．Tim's programmes were placed on to the Internet in 1990.

C．The World Wide Web will have an effect (影响) on social development.

D．Tim Berners-Lee made a great contribution to the computer science.

语篇解读：本文是一封回信，回答了来信中提出的问题，并对有兴趣从事新闻工作的人

提出了建议。

1．解析：通读全文可知作者谈到新闻工作的重要性及如何成为一名出色的新闻工作者，由下文中的than可知，这是一个比较句，no ... than意为"没有......比......(更)"。在作者看来，对喜欢写作的年轻人来说，没有哪一个职业比从事新闻业回报更高。

答案：B

2．解析：由下面的"Of course I'm not speaking of ________ rewards"中的rewards及语境可知B更符合文意。

答案：B

3．解析：由后面的in writing提示，应选用与之搭配的词an interest，意思是"对写作有兴趣的年轻人"；C项curiosity常与about 搭配使用，因此应排除。

答案：A

4．解析：由下句的"Anyone who wants to get rich should choose some other ________．"以及"But journalism pays a living wage"判断，作者谈论的不是物质回报，而是精神上的、心理上的回报。

答案：D

5．解析：根据前后文中出现的"newspaper work"，"newspaper reporter"等信息词以及本句语境可知，此处所指为"职业"，故应填occupation。答案选C。

答案：C

6．解析：perform one's duty"做自己的工作"。为固定搭配。carry 和take要表示"承担责任，做自己的工作"，需要分别用carry out one's duty 和take on a duty。从搭配来看，只有B项可选。

答案：B

7．解析：新闻工作者社会责任重大，他们拿工资，不可能富有，但他们常常揭露社会的黑暗，帮助弱势群体，所以他们会觉得自己比银行行长还重要。A项wealthy与文章主旨相悖。

答案：C

8．解析：下文给出了几个如何成为出色的新闻工作者建议，故信中询问：怎样成为新闻工作者？

答案：A

9．解析：新闻工作的特点是采访和写报道，电脑一般是用来写稿子，编辑稿子，故应用use一词，表示学习使用计算机，而不是维修(fix)或获得(get)。

答案：C

10．解析：对记者而言，知道使用计算机(强调操作技能，而不是知识，如设计软件等)就足够了。结合语境可知选D。

答案：D

11．解析：这种技能可在学校也可从书本上获得，书上一般会详细讲解具体的操作步骤。受汉语影响，容易误选A项(写)或C项(介绍)。如选A项，其正确结构应为：... a book that is written about ...。此处的explain(讲解，解释)符合文意。

答案：D

12．解析：根据下句所提还学历史、管理、数学可推测此处应该选"语言"最符合文意。

答案：B

13．解析：由文化常识知西方国家的科学(science)科目包括物理、化学和生物。因此，应排除A、D两项。C项属语言类，且下文的"Foreign languages are also good to know"已提到，故排除。

答案：B

14．解析：新闻工作者面对的是新闻，而新闻是每天发生的，故用happen。

答案：A

15．解析：前面说到每天发生的事情不简单，因此要明白它们就得多懂点各种知识。know a lot"懂得不少"，符合语境。

答案：A

16．解析：由上下文"for school papers" 的提示可知，如果学校办报，你应该为其投稿。

答案：C

17．解析：常识告诉我们，往往有工作经验的人容易被雇用。此处指：曾经为学校报纸工作过的人。editing和printing都属于working for papers的范围。

答案：D

18．解析：根据句子结构，与前面的you一致，应用反身代词yourself。此处表示"使(你自己)为......做准备"。

答案：A

19．解析：为从事新闻业而做的准备工作是要读所有能读的东西，尤其是报纸和杂志，因为新闻工作者的主要职责就是出版报纸和杂志。specially"专门的"，不合语境。

答案：C

20．解析：前文讲述了为找一份从事新闻业的工作如何做准备，所以要求读报纸和杂志，并且读完后与人讨论形成自己的观点。form意为"形成，构成"，符合语境。

答案：C

Ⅵ.

答案：D

2．解析：细节理解题。从"In the 1980's, scientists were already using a primitive version (原始版本) of e-mail."这句话中可以得出答案是80代。

答案：C

David Braben is a very well?known game developer who runs the UK development studio, Frontier Developments, but is just as well?known for being the developer of “Elite”．Over his career his studio has brought us the “Rollercoaster Tycoon”series and most recently “Kinectimals”. In the background, however, Braben has been trying to solve another problem: getting programming and general learning of how computers work back into schools.

Braben says that education since we entered the 2 000s has turned towards teaching useful skills such as writing on computer, how to get information, and learning basic computer use skills. And those have supplanted more computer science?like skills such as basic programming and understanding the hardware (硬件) contained in a computer.

His solution is not to create his own course, but instead to make a low?cost PC that can be given to kids for free and his courses are built up around their use.A personal computer is important for each student to have in class.When we say “low cost”，we mean the cost is so low that even “One Laptop per Child”would be realized.Braben has developed a tiny PC.How much is the cost？$25.This is the answer to anyone that says he/she can't afford a computer.The hardware being offered is good, too.The new tiny PC will let the user look through the Internet and give the user a fully functional (功能) computer to play with.And it can be carried in your pocket or on a key chain.

This tiny cheap PC is going to be given to schools through a new charitable foundation (慈善机构) called the Raspberry Pi Foundation.It will help computer science studies in schools.Braben says he hopes that they will be given within the next 12 months.

1．What David Braben has been trying to do is ________．

A．running the UK development studio

B．letting children learn science?like skills

C．creating more advanced computers

D．creating more computer games

2．What does the underlined word “supplanted”in Paragraph 3 probably mean?

3．What do we know about the PC David Braben is developing?

A．It is small and very cheap.

B．Its hardware isn't very good.

C．It isn't a fully functional one.

4．What kind of person do you think David Braben is?

C．He is rich, selfish and successful.

D．He is able, famous and warm?hearted.

Petra may be the treasure of the world, hidden among mountains. Its most beautiful scenery makes it the greatest ancient site still?standing nowadays. Common sense says，“Perhaps there's nothing on the planet that resembles it.”Without doubt, there's nothing on the world that resembles it. The rock?carved (雕刻的) rose?red town of Petra is filled with mysterious_charm;_it had been “designed to strike wonder into all who entered it”．Petra is the most well?known and beautiful site in Jordan that is about 262 km south of Amman, and 133 km north of Aqaba. The Dead Sea is 80 kilometers north of it. It was the legacy from the Nabataeans, who settled in the southwest of Jordan a lot more than 2，000 years back. Because of its excellent culture, buildings and many water channels, Petra has become a UNESCO world heritage site and one of the New Seven Wonders of the World that attracts visitors all over the world.

To get there, you must pass through a kilometer long, cool, dark and narrow gorge (峡谷) whose two high sides keep the sunlight out. Suddenly the gorge opens right into a natural square covered with Petra's most well?known monuments (遗址), which glow in the bright sun.The old town shows the visitors its beautiful look. It leads people to think about the creativity of the Nabataeans who made Petra as their capital.

Petra flourished for more than 400 years at about the time of Rome until it had been occupied through the Roman legions in 106 AD. Petra has 800 monuments, including buildings, tombs, baths, halls, temples, and streets, which were mostly carved in the pretty sandstone.

Petra sights are in their finest at the beginning of morning and late afternoon. Once the sun warms the colorful stones, you will see the greatness of Petra since it was seen first when discovered in 1812 after being lost through the 16th century for nearly 300 years!

1．From the text we can learn that ________．

A．Petra is on the top of a high mountain

B．Petra is a palace of the king in the old days

C．no place in the world can be similar to Petra

D．the Nabataeans built Petra in 106 AD

2．What does the underlined part “mysterious charm”in Paragraph 1 mean?

A．The unbelievable power to attract people.

B．All kinds of visitors from the world.

C．A number of usual places of interest.

D．The shops, restaurants and hotels.

3．Visitors' reaching Petra ________．

A．must be disappointed

B．must be very convenient

C．must be very comfortable

D．may not be very easy

4．What can we learn from the text?

A．You'd better enjoy the beautiful scenery at the beginning of morning and late afternoon.

B．Because it had been occupied, Petra was lost through the 16th century.

C．Petra was developing quickly and strongly for more than 800 years.

In America, Virginia Beach has all the elements of a classic seaside resort：brilliant beaches, a lively boardwalk, plenty of restaurants and nightspots, and amusement rides sure to appeal to kids.Many people believe Virginia Beach is at its best in the off?season, when the town is less crowded but the weather is still mild.

Meanwhile, some safety tips should be followed, enjoying the happiness and excitement the beach offers.

The number 1 safety tip concerns ocean safety：pay attention to Flag conditions posted on the lifeguard stands. Lifeguards post a red flag to warn when the ocean water is dangerous. Take them seriously！Tourists from land?locked regions are particularly easily attracted by the magic of the waves.However, a calm ocean can become risky without warning.Make sure you swim near a lifeguard.Swimming without lifeguard protection is almost five times as great as drowning at a beach with lifeguards.

Never swim alone.Many drownings involve single swimmers.When you swim with someone else, if one of you has a problem, the other may be able to get help, including signaling for assistance from others.

Don't fight the current.The facts show that 80%of rescues by lifeguards at ocean beaches are caused by currents.These currents are formed by surf and gravity，because once surf pushes water up the slope of a beach, gravity pulls it back.This can create concentrated rivers of water moving offshore.If you are caught in a rip current, don't fight it by trying to swim directly to shore.Instead, swim parallel to shore until you feel the current relax, then swim to shore.Most rip currents are narrow and a short swim parallel to shore will help bring you to safety.

Science Daily (May 28, 2010) —Researchers at Oregon State University (OSU) have made important progress in work that should lead toward robots that can not only walk and run very well, but use little energy at the same time.

Studies are moving closer to designing robots that could do dangerous work, create prosthetic limbs (假肢) for humans that work much better than in the past, or even help some people who use wheelchairs to get “walking”abilities.

“Researchers have been working toward robot movement for a long time，”said Jonathan Hurst, a professor at OSU.“What we've done is to study what behavior is really possible for a robot.”

The movement of humans and other animals is difficult to https://www.360docs.net/doc/137808020.html,ing little energy, they can move easily over hard areas, and enjoy balance from muscles.They have different ways to deal

with forces, such as holding something hard in place rigidly (牢牢地), like the act of holding a cup of coffee level during a car ride.In their recent studies, the OSU researchers proved that these two_abilities are mutually exclusive (相互排斥的)．Humans deal with this problem by using pairs of muscles. For a robot, the more able it's to do one of these tasks, the less able it is to do the other.

Presently, robots that can walk and run must be as rigid as possible while walking.But this way uses a lot of energy.The OSU researchers are working toward something that has similar or better performance, but uses far less energy, and is closer to the abilities of animals.

“So there's no reason why we shouldn't be able to build robots with good movement ability，”Hurst said.“Clearly this might be useful in highly dangerous situations.But I could also see great improvements possible with prosthetic limbs (假肢) that work much better than present technology.”

1．The robots being studied by researchers at OSU ________．

A．cannot walk

B．use little energy

C．do better than before

D．can run faster than humans

2．Which of the following have researchers been studying all the time?

A．The robots' movement.

B．The robots' weight.

C．The robots' sizes.

D．The robots' walking speed.

3．The underlined words “two abilities”in Para.4 refer to ________．

A．walking and running

B．walking and holding

C．moving and using little energy

D．moving and balancing

4．According to Jonathan Hurst, we know that robots with good movement ability ________．

A．can be used in medical science

B．are only used in highly dangerous situations

C．will hardly be created in the future

D．will have a bad influence on man
