look up the dictionary

汉语中的“查字典”，说成英语通常是 look up sth in a dictionary 或 consult [refer to] a dictionary。如：

I refer to the dictionary frequently. 我经常查阅词典。

You can look the word up in the dictionary. 你可以在词典里查这个词。

He often consulted a dictionary when he read the book. 他读这本书时经常查字典。

I looked the word up in the dictionary to refresh my memory of its exact meaning. 我查了词典，以便弄清这个词的准确意思。

I often look up the words I don’t know in the dictionary or on the Internet. 我经常在字典里或网上查找我不认识的单词。

“Is that the correct spelling?” “I don’t know—look it up in a dictionary.” “那是正确的拼写吗?”“我不知道——查查词典吧。”

I didn’t know what “loquacious” meant and had to look it up in a dictionary. 我不知道loquacious这个是什么意思，所以只好查了词典。

有不少人认为英语习惯上不能直接说 look up the dictionary, 其实这种表达在英语中也可以用，只是比较少见而已。例如：

I spend more time looking up the dictionary than reading the book. 我读这本书时查字典的时间还多些。——摘自 L. G. Alexander 编《新概念英语》(外研社)

Look up the dictionary and explain the meaning of the italicized words.

look at a book?

1. 表示阅读性地“看书”(即读书)，一般要用动词 read。如：

Don’t read such books. 不要读那样的书。

He is reading a book on Shakespeare. 他在看一本关于莎士比亚的书。

但是，在许多情况下，“看书”只需用read 就够了(尤其是泛泛地表示“看书”时)，无需后接book作宾语。如：

In the evening I usually read. 晚上我常常看书。

This light is too poor to read by. 这光线太暗不能看书。

I read much less now than I did at school. 我现在看书远比我上学时少。

2. 若不是表示阅读性地“看书”，而只是大概地看一看，比如看看书的封面、定价、内容提要等，或者回答问题时看看书的某些章节或字句等，或者是考试时悼词楸镜龋此时都不宜用动词read, 可用look at, see 等。如：

Can I look at those books? 我可以看看那些书吗?

Jim demanded to see my books. 吉姆要求看看我的书。

Please answer my questions without looking at your books. 请不看书回答我的问题。

Students must not look at their books during examinations. 学生考试不准舞弊。

一、就近一致原则

1.由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等连接两个或两个以上的并列主语时，通常根据就近一致原则，谓语动词要与离它最近的主语在数上保持一致。

2.here/there引导一个句子而主语又不止一个时，通常根据就近原则，谓语动词要与离它最近的主语在数上保持一致。

二、意义一致原则

1.谓语动词必须用单数的情况

(1)表示学科的名词以及works(工厂)，news(消息)等作主语时，虽然本身为复数形式，但表示单数意义时，谓语动词仍用单数。

Politics is his favorite subject.

(2)表示某些组织机构的名词、书/报名、国名、地名等作主语时，虽然形式上是复数，但所表示的意义是单数，所以谓语动词用单数。

2.谓语动词必须用复数的情况

表示总称意义的名词，如people，police，public，cattle等作主语时，谓语动词用复数。

The police are searching for the murderer.

3.谓语动词的形式依据主语表示的意义而定

(1)集体名词，如family，class，group，team，club，company，government，population等作主语时，谓语动词的形式根据其在语境中表示的意义而定。当其表示集体意义，强调整体概念时，谓语动词用单数;当其表示集体中各个组成部分，强调个体概念时，谓语动词用复数。

As far as I know，his family is not very large but the family are all music lovers.

(2)“the+形容词/分词”表示“一类人”时，谓语动词用复数。

The poor were looked down upon in the old days.

三、语法一致原则

(1)“a/the+名词单数+and+名词单数”表示一个人(双重身份)，谓语动词用单数。

The teacher and poet often gives lectures around the city.

(2)“a/the+名词单数+and+a/the+名词单数”表示两个人，谓语动词用复数。

The teacher and the poet have just arrived.

(3)“every+名词单数+and+every+名词单数”表示每一个人，谓语动词用单数。

(4)通常由两个部件组成的物品如：a knife and fork (一副刀叉)等作主语，谓语动词用单数。

Bread and butter is not to his taste.

2.表示时间、数量、长度及价格的名词，尽管有时是复数形式但常被看作是一个整体，谓语动词用单数形式。

Is fifty pounds enough?

3.“分数/百分数+of+名词”作主语时，谓语动词的形式根据of后的名词的形式来定，如果名词是可数名词复数，谓语动词用复数形式;如果名词是单数可数名词或不可数名词，谓语动词用单数形式。

Two-thirds of the books are about science.

Only 30% of the work was done yesterday.
