expect sth.to do.固定短语，“期望某事发生”，sth. be expected to do.意为”某事有可能发生“。
make sth. clear to sb为固定搭配，意为“向某人阐明某事，使某人弄清某事”。

(完整word)各类从句讲解
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句.所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词,关联词如下:①主从连词:that （无意义)， whether (是否), if （是否）（在句子中不充当任何成分）②连接代词:who （谁）， whom (谁）， whose （谁的)， what (什么)， which (哪一个)③连接副词：when （什么时候)， where (什么地方）， how （怎样）， why （为什么）主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外,可以用whatever， whichever， whoever, who（m)ever等连接代词引导名词性从句，来加强语气.下面分别对各种名词性从句进行介绍(一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us。
月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide. 会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重,因此通常可以把it放在句首,作形式主语，而将主语从句放在后面.例如上面的句子可以分别改写为:It is certain that he will come to the discussion。
(完整word版)高中英语名词性从句讲解
适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。
它包含主从句、从句、表从句和同位从句。
名性从句是中学段的一个重要法目，在年的高考取几乎都波及到，而且每年的命各有化。
解析届高考名性从句考的焦点主要有以下六个方面1. 考名性从句的序2. 考引 that 与 what 的区3. 考 it 在名性从句中作形式主或形式的用法4. 考 whether 与 if 的区5. 考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。
所以，四种从句通称名性从句。
引名性从句的接可分三：接： that, whether, if（不充任从句的任何成分）接代： what, whatever, who, whoever, whom, whose, which.接副： when, where, how, why1.主从句作句子主的从句叫主从句。
主从句往常由附属that ，whether ，if和接代what ，who，which ，whatever ， whoever 以及接副 how， when， where， why 等引。
that 在句中无，只起接作用；接代和接副在句中既保存自己的疑含、又起接作用，在从句中充任从句的成分。
比如：What he wants to tell us is not clear.他要跟我什么，不清楚。
It is known to us how he became a writer.我都知道他是如何成一名作家的。
Where the English evening will be held has not yet been announced.英晚会将在哪里行，没有宣告。
有防止句子重脚，常用形式主it取代主从句作形式主放于句首，而把主从句置于句末。
主从句后的一般用数形式。

名词性从句归纳一、名词性从句概说、结构与功能名词性从句是起名词作用的从句，其功能相当于名词词组，在复合句中可作主语、宾语、表语和同位语。
与之对应的名词性从句分别为主语从句、宾语从句、表语从句和同位语从句。
二、主语从句1、主语从句的类别●以从属连词that 引导的主语从句。
（从句位于句首，that通常不省略）→ That she will come to the conference has excited every one of us.●以从属连词whether 引导的主语从句。
（从句置于句首时一般不用if来代替whether）→ Whether we’ll go outing depends on the weath er.●以连接代词（what, whatever, who, whoever, which, whichever等词）引导的主语从句。
→ Whoever will be in charge of the project hasn’t been decided yet.【注】what 与that在引导主语从句时，what 不但起连接作用，而且还有具体意义，意为“所…的”，相当于the things that结构；而that则无词义。
即如果从句中不缺少主语或宾语时，选择that，否则用what。
●以连接副词（when，where, how, why 等词）引导的主语从句.→ When the new road is open to traffic has not been made clear.2、用it 作形式主语的主语从句注：以下几种特殊情况必须用it作形式主语：⑴ It is + adj. + that 从句常见的形容词有：necessary，right，likely，wrong，important，certain，clear，obvious，strange 等。
→ It is likely that there will be a snowstorm tomorrow.⑵ It is + noun + that 从句常接这种句型的名词有：a pity, a shame, good news, a fact, an honor, a wonder, no wonder 等。
→ It is a pity that you didn’t attend the lecture [讲座] yesterday.⑶It is + 过去分词常见的分词有：said, heard, reported, decided, suggested, advised, ordered, thought, considered, pointed out, well known, hoped, turned out 等词→ It is said that the professor has already succeeded in carrying out this experiment.⑷ It + 特殊动词+ that从句常用于这种结构的动词有：seem，happen（碰巧），appear，occur 等。
→ It seems to me that you object to the plan.It happened that I didn’t take any money with me.⑸It doesn’t matter how/whether…结构中的主语从句→It doesn’t matter whether he is wrong or not.三、宾语从句1、动词的宾语从句⑴大多数动词都可以带有宾语从句→ We all expect that they will win this match.常见的动词有：hope, tell, say, know, think, consider, imagine, hear, expect, suppose, guess 等。
⑵有些“动词+副词”结构也可带宾语从句。
→ I have found out that all the tickets for the concert have been sold out.⑶可以运用形式宾语it的宾语从句：①动词find, feel, think, consider, make, believe 等后有宾语补足语时，需要用it 作形式宾语而讲that宾语从句后置。
→ I think it necessary that we take plenty of hot water every day.I have made it a rule that I keep diaries.② 动词hate, take, have, see to等词在带宾语从句时习惯上需要在宾语从句前加it。
▲（若宾语从句是“WH”系列引导，其后有to be短语作宾补，则不可以用it替代。
）→ I take it that you will agree with us.We all consider what you said to be unbelievable.2、介词的宾语从句⑴一般情况下，介词后面只能用“WH”系列连接词来引导的宾语从句。
→ We are talking abo ut whether we admit students into our club.▲用that引导从句作介词宾语时，需要用形式宾语it替代，然后将that从句发在最后。
→ You may depend on it that I shall always help you.⑵偶尔的情况下，except, but, besides, in四个介词后面可接that引导的宾语从句→ I know nothing about my new neighbor expect that he used to work in a company.I prefer his plan to yours in that I think it is more practical. (in that 表示原因)He would have failed but that you helped him. (but that 要不是，若非)3、形容词的宾语从句⑴sure, certain, glad, pleased, happy, afraid, surprised, satisfied, sorry等表示“情感”色彩的形容词后也可以带宾语从句。
→ He is sure that they will make it in spite of the terrible weather.⑵当主句中的谓语动词是think, say, guess, suppose, suggest, believe, feel, consider时，宾语从句的引导词表示疑问时，需要放在句首。
→ Who do you think the public might choose as their favorite singer this year?4、if和whether在宾语从句中用法的区别▲ Whether和if在作“是否”讲时：Ⅰ在下列几种情况下只能用whether。
⑴当被引导的宾语从句置于句首时。
→ Whether they will join in the winter camp I don’t care.⑵引导的宾语从句作介词的宾语时。
→ We are talking about whether he will come next week.⑶从句中有“or not”时。
→ I don’t care whether the work will take long or not.⑷引导词后接动词不定式时。
→ I am just wondering whether to stay for another hour or just start off right away.⑸当从句部分用if 引导时，容易出现歧义时。
→ Let me know whether you can come.*(此句话中若出现if，则不能判定if表示的含义为“是否”还是“如果”，容易有歧义。
) Ⅱ在动词ask, know, wonder, 词后，只能用if。
5、不可省略that的宾语从句⑴当that作learn, suggest, explain, agree, wonder, prove, mean, state, feel, hold等动词的宾语时，常不省略。
→ I have learnt that most of the students who are interested in Chinese take interest in English.⑵当宾语从句比较长时，that不省略。
→ We all think that what the public is badly in need of is nothing but the development of economy.(我们大家都认为所急需的不是别的正是经济发展.)⑶当主句状语置于宾语从句之前时。
→ I realized at once that I had done wrong immediately she told me all about this.⑷当宾语从句的状语或状语从句置于其句首时。
→ He told us that, if we could all come to help out, the whole situation would be looking up.⑸当主句谓语动词（或非谓语动词）与宾语从句之间有插入语时。
→ Whe n Marx got to England, he found, however, that his English was so limited that he could n’t go on with his common affairs.⑹当一个动词带有两个或两个以上并列的宾语从句时，此时第一个that可以省略，第二个that不可以。
→ Then he began to talk to us about the French language, saying (that) it w as the most beautiful tongue in the world, and that we must keep it among is and never forget it.⑺当宾语从句的主语是this，that，或this，that为主语的定语时。
