Ⅳ.阅读理解
Each year，road accidents kill a million people and injure millions more.The economic costs are greatest for developing countries.Earlier this year，the United Nations called for a campaign to improve road safety.
One way to avoid accidents is better driving.Another is better roads and bridges.Engineers in the United States have designed ten new concrete mixtures that they think could make bridges last longer.
Professor Paul Tikalsky leads the experiments by a team at Pennsylvania State University.He says bridges made of concrete now last about twenty－five to thirty－five years.But he says the new mixtures might extend that to seventy－five or even one－hundred years.
Concrete is made of stone，sand，water and cement (水泥)．The materials in the cement hold the concrete together.Ancient Romans built with concrete.Yet strengthened concrete bridges did not appear until the late 1800s.People keep looking
for new ways to improve concrete.Professor Tikalsky says it is one of the most complex of all chemical systems.
The new mixtures designed by his team contain industrial waste products.He says these make the concrete better able to resist damage from water and salt over time.One of the products is fly ash.This is released into the air as pollution when coal is burned.
Professor Tikalsky says particles (颗粒) of fly ash are almost exactly the same size and chemical structure as Portland cement.This is the most costly material in concrete.So using fly ash to replace some of it would save money.
Over the next two years，engineers will study ten bridges in Pennsylvania.These were built from the different cement mixtures designed by Professor Tikalsky’s team.He says longer－lasting bridges could save the state more than 35 million dollars a year.And he says the materials would be environmentally friendly.
The federal government is paying for part of the research.Engineers anywhere can use the technology.Professor Tikalsky says some of the ideas have already been put to use in China，the Philippines and other countries.
41．Why did the United Nations launch the campaign? A．Because the United Nations wanted to reduce road accidents and economic costs. B．Because two million people were killed in the accidents.
C．Because engineers wanted to design ten new concrete mixtures.
D．Because the United Nations made bridges of the new mixtures which could last for about 20 to 35 years.
42．What does the underlined word “This” in the sixth paragraph refer to? A．Fly ash. B．Portland cement. C．Sand. D．Chemical. 43．Which of the following statements is TRUE?
A．Ten new concrete bridges have already been built in the United States. B．A new concrete bridge could last 50 more years than an ordinary concrete one. C．People didn’t know how to build with cement until the late 1800s. D．Water and salt won’t do any damage to bridges over time. 44．What can we conclude from the passage?
A．Engineers have to pay a lot of money to use the new bridge technology. B．Pennsylvania State University is paying all the money for the research. C．Bridges built with fly ash are cheaper than common bridges. D．Fly ash is much more expensive than Portland cement. 45．What does the passage mainly tell us? A．The causes of road accidents. B．The advantages of fly ash.
C．The measures of avoiding road accidents.
D．Latest information about long－life concrete bridges.
课时作业答案
Ⅰ.单项填空
1．A v．－ing形式先于decide发生，故用A项。
2．D 句意为：……尽管被告知停止，但那位激动的演讲者还是继续在会上讲话。演讲者是被告知，故用过去分词，他本人感到激动，故用excited。
3．C 非谓语动词的用法。该结构的逻辑主语是下文中的“most students”，所以应用被动形式，故排除A、D；由句子结构分析，空格部分在句子中作主语，故只能选C。
4．A glance at意为“匆匆一看”，符合题意。stare at意为“盯着看”；watch意为“注视”；notice意为“注意到”。
5．C 考查名词性从句。It作形式主语，that从句作真正主语。第二个空what引导宾语从句，在从句中作宾语“……的地方”。
6．B 连词辨析。答语yes后省略了I will (go to Kathy’s wedding party)，意思是：不，我去，如果我被邀请的话(If I am invited)。
7．C 本题考查非谓语动词的用法。从后面一句话所提供的语境分析，不知何时能完成，所以是“最近一直在设计”。副词recently应该和完成时态连用，后面又决定了进行中。因此使用符合两者要求的现在完成进行时态。
8．B anxiety焦虑；relief放松，放心；view观点；judgment判断。由题干后半句可知选B项。to one’s relief “令人如释重负的是”是固定短语。
9．C 由句意可知，此处应指“保证”，故选C项。A项后应加of或about，D项后应加of。
10．C 句意为：我们随处可见纪念碑，那些为人类和社会做出巨大贡献的人将永垂不朽。考查名词词义辨析。contribution贡献；advance前进，提升；effort努力；achievement(个人取得的)成就。make contributions to为固定短语，词义为“为……做出贡献”，符合语境。
11．B
12．A be fortunate to do sth./be fortunate in doing sth.意为“幸运地做某事”。 13．A 14.C 15.D Ⅱ.翻译句子
16．We’ll have to finish the job，however long it takes. 17．The problem is how to spend the sum of money. 18．Jack encouraged me to apply for the job.
19．We made our way down the hill towards the town. 20．Marx’s ideas gave birth to communism. Ⅲ.完形填空
21．C 由后面的with a lot of friends可推知，此处为“受人欢迎的”(popular)。 22．D 由后面的定语with only a few friends...及与前面的对比关系可推知应选different。
23．A make a point表示“立论，证明论点”。句意为：我要证明的论点是任何人都有可能成为瘾君子。
24．B figure out表示“领会到，断定”。句意为：我领会到这一点是通过我自己成为瘾君子的经历。
25．A 由下文的I had never lived with...可推知作者以前“一直是一个很受欢迎的人”。
