题文

Some experts feel that the automobile is to “die”. They e a day in the not­too­distant future when all autos will be abandoned and allowed to become rotten iron and steel rubbish. __小题1:__ They think that the car will remain a leading means of urban travel in the near future._小题2:_ It should become smaller, safer, and more money­saving, and should not be powered by the petrol engine. The car of the future should be far more pollution­free than prent types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic jam. _小题3:_When the auto enters the freeway system, a retractable arm, which can be moved inwards or backwards, will drop from the auto and touch a rail that is similar to the subway trains electrically powered from the system, and control of the vehicle will pass to a central computer. 小题4:_The driver will u a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and rerve space for the car all the way to the correct exit from the freeway. _小题5:_ It is guesd that an automated freeway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a prent­day freeway.A．Other authorities, however, think the auto is here to stay.B．The computer will then monitor all of the car's movements.C．One propod solution to this problem is the automated freeway system.D．Experts have different views on what role autos will play in the near future.E．The motorcar will undoubtedly change significantly over the next 30 years.F．Drivers in the freeway system can sit back and do nothing but control the direction.G．The driver will then be free to relax and wait for the sound speaker that will warn him of his coming exit.1．______ 2.______ 3.______ 4.______ 5.______ 题型：未知难度：其他题型

解析

本文属于科普知识类，为大家预测了将来的汽车是什么样子，以及怎样操控它。小题1:A 首先根据文章开头的“Some experts...”可知与A项的“Other authorities”构成some...others的结构；其次，根据后文说到“...remain a leading means of urban travel”可知，本句和前面说的“汽车消失”形成对比。故选A项。小题2:E 根据空后的“It should become smaller，safer，and more money­saving，and should not be powered by the petrol engine.”可知选E项。小题3:C 根据空前的“the main problem”及后文的“the freeway system”可知C项起到了承上启下的作用。小题4:B 根据空前的“control of the vehicle will pass to a central computer”可知选B项。小题5:G 本段都是讲述电脑控制汽车是如何运行的，故选G项。

考点

据考高分专家说，试题“Some experts feel th.....”主要考查你对 [序数词 ]考点的理解。 序数词

序数词的概念：

表示顺序的数称为序数词。如：first, cond, third, fourth。

序数词的构成与用法：

1、序数词的构成：①一般来说，是由相应的基数词加词尾th构成。   例：four＋th→fourth   six＋th→sixth    ven＋th→venth   ten＋th→tenth②下面这些基数词在变为序数词时，有特殊的变化。例：one→first    two→cond    three→third    five→fifth    eight→eighth    nine→ninth    twelve→twelfth③十位整数序数词的构成方法是将基数词的词y变成i，然后再加eth。例：twenty→twentieth    thirty→thirtieth    forty→fortieth    ninety→ninetieth④两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。例：twenty－one→twenty－first    thirty－five→thirty－fifth    a hundred and fifty－three→a hundred and fifty－third2、序数词的用法：①序数词在使用时，一般加上定冠词。例：the first book    the cond floor    the third day    the fourth week．②序数词在多数情况下都用作定语，有的也可以作表语、主语和宾语。例：The may1st is Labour Day. 五月一日是劳动节。    My room is on the cond floor. 我的房间在二楼。    The first is larger than the con.（主语）第一个比第二个大。    Read the book from the first.（宾语）从开头读这本书。    You'll be the sixth to write.（表语）你将是第六个写的。③序数词的前面可以加上不定冠词，用来表示“再一”，“又一”的意思。例：You may have a third try. 你可以第三次尝试。

序数词知识体系：

 

约数的表达方法：

用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。 如：The boy bought dozens of pencils.       Thousands of people died in the earthquake. 注意： (A)：dozen, score, hundred, thousand, million等表示确切数量时，不用复数。 如：five dozen (of) eggs   五打鸡蛋    hree hundred people  三百个人

分数词的构成和用法：

1）分数词构成法：分数词（FractionalNumerals）由基数词和序数词构成，基数词代表分子，序数词代表分母。除了分子为1的情况下，序数词都要用复数形式：如：1/4：one-fourth    5/9：five-ninths    2/3：two-thirds   17/5：three and two-fifths   7/12：ven-twelfths   379/8：forty-ven and three-eighths此外还有下面表示法：如：1/2：a(one) half    1/4：a(one) quarter    3/4：three-quarters    9/4：two and a quarter    3/2：one and half     31/4：ven and three quarters
