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。

1、不定式做主语一般表示具体的某次动作。动名词doing表示习惯的,经常的动作。
e.g:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(对等)
注:1).不定式作主语时,谓语用单数
2).当主语较长,谓语较短时,常用it做形式主语,而将不定式放到谓语的后面。
it做形式主语,不定式放在谓语动词之后常用于下列结构中:
(1)Itis/was+adj.+ofsb.todo…
(2)Itis+adj.+forsb.+todo…
Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary
(3)itis+a+名词+todo...
Itisapity/apleasure/apleasantthing/one’sduty/anhonor/ashame/acrime/noeasyjob…todo
Ittakes(sb.)sometime/courage/patience…todo…
Itrequirescourage/patience/hardwork…todo…
注意:probable和possible均可作表语,但possible可以用不定式作真实主语,而probable不能用不定式作真实主语。
Itisprobableforhimtocometothemeeting.(错)
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.
