肯定选C,总共有以下几种形式

狂奔的牛群
看下动物世界就知了,每年牛群迁徙都将一切踏于蹄下

主语computers谓语send off
宾语e-mails containing it做后置定语修饰宾语 解释为包含XX的电子邮件

dozen和hundred 用法相似
你有没有见过two hundreds of,显然没有嘛

（蜜蜂）一天可以对成百上千的花进行授粉.

searching for nectar and pollen 不是定语,而是伴随状语,也就是与谓语动词 visit 同时发生的伴随行为,即它们一边 visit flowers 一边 searching for nectar and polle.这个句子也可以改为——
并列谓语：They are able to visit dozens or hundreds of flowers in one day and search for nectar and pollen.
while引导的从句：They are able to visit dozens or hundreds of flowers in one day while they are searching for nectar and pollen.
可以这样翻译：
1、它们在一天内能够飞临数十朵或者上百朵花寻觅花蜜和花粉.
2、在采集花蜜和花粉的同时,它们在一天中能够造访数十朵或者上百朵花.

dozen 一打 12
dozens of 几十个 很多
dozen 前有具体数字时 或有a many several 修饰时 dozen 不加s.
如 three dozen egges.
所修饰的名词 有these 或是代词时 dozen 后加of
如 three dozen of these egges
three dozen of them

他有这种情况大概十多次了.

D

选 D : open into是个短语,意思是通往,通向
B.C 选项的时态与定语从句的一般现在时不能搭配
A 选项是把open当形容词,意思讲不通

Ａ

It is said that 主语...=主语is said to...translate，发生在过去用to have done，表示不定式动作发生在谓语动词之后，而且《红楼梦》是被翻译的，用被动语态。

each other是相互的意思

在对面的墙上挂着一张地图和许多图片.

这只是我能提供证明的几十个案件中的一个例子
but one 就是only one 的意思,唯一的,后面的eases应该是cases

to be accused of .
正如报纸中所报道的,数十人被捕但无一人被指控抢劫.

two dozen of 表示两打
一般前面有数字的,dozen都不加s的
例如 five/ nine dozen of beer 五、九打啤酒
一般好像没有two dozens of的,只有dozens of,表示几十
two dozen of sth.
dozens of sth.
这就好比hundred,thousand那样
two hundred,five thousand
hundreds of ,thousands of

选d

A.典型的时间问题.只需要搞清楚这个said 和 translate的时间关系(最喜欢这样考).那么很明显,肯定是这些书籍先被译成了...,才可能有后人去"据说它被译",是吧?所以translate是在译之前,要表达这个就必须用到to have done,排除BD.而被动语态问题你已经明白了,所以排除D.

A

dozen前面接数词时不用复数形式，dozens of表示很多。

B.这句句子没有连词,所以逗号后的句子不能用谓语动词,所以D错.它的独立主格是the message.要用非谓语,然后根据意思所有人抱怨他们在国庆节的超量作业,这里的all指代classmates and other teenager.所以人抱怨事情,是主动的故用complaining.不定式C表将来和目的而过去分词A表被动,都不对.

A

许多商店；几十个贝壳；几千本书；几十个包；几百万美元；两打；四十；一个半小时；在他二十几岁的时候；在他九十几岁的时候；在……岁的时候；第一眼；急救；二手店；第二大

pack in dozens 成打打包
two dozen oranges 两打橘子
i have dozens of things to do.我有很多事做
dozen 的意思是一打 12个 dozens of 是形容词 十来个

A,意思是说the Red Chamber在上个十年间就已经被翻译成了很对种语言

Dozens Of world leaders and royals from around the globe might had to visit McDonald last week as their personal chefs met in Thailand for a holiday.The chefs enjoyed a week of cooking parties and a break from their demanding duties.The group made up of 36 cooks,nearly all members of the Club of the Chefs to the Heads of State.This group says it is the most special gastronomic club in the world.
The personal cooks to kings,princes and presidents went to Thailand for their yearly meeting.In a rare change from the usual,they were given the best wine and food as if they themselves were the leaders of nations.But not all of them were in Thailand.French President Jacques Chirac's personal chef could not go because he had to be in France for a state visit.
For those who went to Thailand,it was a chance to discuss global cooking trends,taste local dishes,and perhaps pick up a few ideas to try out on their employers back home.
US President George W.Bush's cook,Walter Scheib,said:“I love Thai gingers and chillis and the wonderful curry sauce.I will use ideas from Thailand when I cook for the president and his wife.” Scheib said Bush's choice of food,like his conversation,is very typical of the southern US:spicy meat flavored with wood smoke.
Lionel Mann,the long-time chef to Britain's Queen Elizabeth II,described the food eaten by the royals in Bucking Palace as classical French and traditional English.Mann is retiring this month after 42 years of feeding the royal family.
Denmark's royal family perhaps has a more modern view of cooking traditions- it enjoys food cooked by a Japanese chef called Mr.Takeshi.Japanese favorites such as sushi appear on the palace menu,said Takeshi.
Prince Albert of Monaco is “quite fond of cooking”,according to his chef Giles Brunere.Brunere often helps the prince with difficult dishes when he decides to cook a meal for his friends.

many

一、dozen表示“ 打,十二个”的意思,而score表示“二十”的意思.
二、两词与数词,a,many,several连用修饰名词复数时,都要用单数,其后的介词of有无均可.但是,习惯上score多与of连用,而dozen很少与of连用,如：two score(of)workers,three score and ten people,several dozen children,many dozen books.
三、两词与of连用（of不省略）时,可用于人称代词宾格（us,you,them）或指示代词（these,those）修饰的名词前,表示所属关系.如：a dozen of these/those pelple,two dozen of them/us,a score of these/those workers.
四、 两词的复数形式与of连用时,表示不确切的数量,意为“许多……,大量的……”.如：dozen of people,dozens of times,scores of people.而some dozen people是“一打左右的人”（大约十二人）与some dozen of people同义.（some）dozen of people是“若干打的人”（几十个人,许多人）.
五、除了上述用法之外,还要注意下列习惯用语：（pack）in dozens〔成打（包装）〕,（sell）by the dozen[论打（出售）],in scores(成批的)
练习：1.The woman wanted to buy three____eggs,but there were only two___eggs left inthe shop.
A.scores of;dozens of B.scores;dozens C.score of; dozen of D.score of;dozen
2.The goods are packed in____and shipped in____all over the world.
A.dozens;scores B.scores;dozens C.dozens;score D.score;dozen
3.The teacher wanted to buy two___books,but the salesgirl only sold him___these books.
A.scores of;dozens of B.scores;dozen of C.score of;dozen of D.score of;dozen
答案：1、D 2、A 3、C

例如 five/ nine dozen of beer 五、九打啤酒

1.一打,十二个〔作为实数及作修饰语时,复数不加 s〕.x0d2.〔dozens〕 若干,许许多多.x0dtwo [three] dozen eggs 两[三]打鸡蛋.four dozen of these eggs 四打这种鸡蛋.some dozens of eggs 好几打鸡蛋.dozens of eggs 几十个鸡蛋.some dozen (of) eggs 一打左右鸡蛋.a dozen of eggs 一打鸡蛋.sell eggs by the dozen 论打售蛋.pack oranges in dozens 按打包装橘子.a round dozen 整整一打.a baker's [devil's,long,printer's] dozen 十三个.dozens of times 屡次.(talk) thirteen [nineteen] to the dozen 〔英俚〕 1.(说个)不停.2.(说得)过分地,迅速地.

可以从以下几个步骤去理
第一步——把句子里大的意群分开
第一群：They are able to visit dozens or hundreds of flowers in one day 它们一天能够采集数十朵或数百朵花上的蜜源.
第二群：searching for nectar and pollen.寻找花蜜和花粉
结论：从第二个意群不难看出,searching for… 是分词短语.
第二步——弄清楚分词短语所具有的的语法功能：
1.用作表语,说明主语所具有的特征
2.用作后置定语,用以修饰一个名词
3.用作状语,说明句中谓语动词发生的时间、原因、条件或方式,或者是与该动词伴随发生的另一个行为状态.
第三步——判断searching for…在整个句子中的作用.
根据句意以及分词短语短语的语法功能,可知这个分词短语在句中充当的是状语.
第四步——改写这个句子
第一种：They are able to visit dozens or hundreds of flowers in one day while they are searching for nectar and pollen.在寻找着花蜜和花粉的同时,它们一天能够在数十朵或数百朵花上采蜜.
结论：这个短语用作时间状语.
第二种：They are able to visit dozens or hundreds of flowers in one day because they are searching for nectar and pollen.因为它们在寻找花蜜和花粉,它们一天能够在数十朵或数百朵花上采蜜.
结论：这个短语用作时间状语或者原因状语.（根据上下文的文理去判断究竟作哪一种状语）

a lot of people or things 许多；很多 ：They arrived in dozens (= in large numbers).他们大批到达了.◊ I've been there dozens of times.我到那里去过很多次.
有很多风险因素会导致心脏病.

此题应选B.容易误选C.本题第二句填代词 it,这容易理解.而第一句不能填 it,则是考生很容易忽视的.显然第一句中的 that I have read dozens of times 是修饰 the book 的定语从句,此句中的动词read不能再接用 it作宾语,因为它已有宾语that(也可省略).

two dozens of police

我的狂想就是有许多美丽、出色的亚洲男人的jy喷洒满我的全身.
dozens of 许多,几十
fantasy 空想,幻想,狂想

这里是介词

只能是two dozen,不能是two dozens.请看下面这篇文章：
dozen的用法
dozen可用复数吗?dozen后要接of吗?你知道dozen的用法吗?请先看下面一道试题：
We already have _________ pencils,but we need two _________ pens.
A.dozen of,dozen B.dozens of,dozens C.dozens of,dozen D.dozens of,dozen of
关于dozen的复数是否加词尾-s的问题比较复杂,大致原则是：
1.当它与具体数字连用时,既不加复数词尾-s,也不后接介词of.尽管有的词书也有 two dozen of 这样的用例,但这已属过时用法,在考试中应避免,如1992年全国高考有一道单项选择题就认为two dozen of为错误选项：
Shortly after the accident,_________ police were sent to the spot to keep order.
A.dozens of B.dozens C.dozen of D.dozen [D]
2.当它不与具体数字连用,而是表示不确定的泛指数时,则不仅要加复数词尾-s,而且要后接介词 of,此时可将dozens of(许多,几十)视为习语.如：
I’ve been there dozens of times.我去过那儿几十次.
She’s got dozens of boy-friends.她的男朋友很多.
下面一例中的dozens加了复数词尾-s也属为似情况：
Pack them in dozens.按打装袋吧.
3.当与 a few,several 等数目不很具体的词连用时,加不加复数词尾-s均可,但需注意：不加复数词尾-s时,其后的介词of可以省略；加词尾-s时,其后介词 of不能省略.如：
several dozen (of) pencils=several dozens of pencils几打铅笔
注：英语较少使用many dozen的说法,要表示类似意思可用dozens of.
4.当它后面的名词受 the,these,those 等特指限定词修饰时,或其后的接的是us,them这样的人称代词时,则此时必须用介词 of.如：
two dozen of these eggs 两打这种鸡蛋
three dozen of them 它们中的3打
注：score,hundred,thousand,million等也具有以上类似用法.

直译：雷鸣般的掌声爆发出来,同时更多的（掌声）紧跟着（响起）
As是时间状语从问的连词,意思和when,while相似.dozen就是一打十二个,虚指很多

of
serving(这个不确定啊）

several是指几个,后面应该加复数,所以应该是several dozens of+复数名词
