学案 3 目标：
掌握主语从句 主语从句
（Noun Clauses as the Subject） 定义：
用作主语的从句叫主语从句，它是名词性从句之一。引导主语从句的连接词有：连词that, whether；连接代词who, what和which；连接副词when, where, how和why。 1) 由what等代词引起的主语从句：
What the teacher said today was quite right. 老师今天说的话是十分正确的。 2) 由连词that引起的主语从句：
That they are badly in need of help is quite clear. 他们急需帮助，这是十分明显的。
但是这类句子在大多数情况下会放到整个句子的后部去，而用代词it作形式主语。
3) 由连接代词或连接副词以及whether引起的主语从句。 Whether they will sell the house is not yet decided. 他们是否卖掉这所房子还没有决定。 4) whatever, whoever也可引导主语从句。
Whatever was said here must be kept secret.
这里说的话都应当保密。
Whoever makes mistakes must correct them. 凡犯了错误的人都必须改正。
注意: 上述例句中的主语从句都是放在句首, 但有时为了使句子结构平衡, 避免 “头重脚轻”, 常用 it 作形式主语, 而把从句放在后面。 例如: It is a pity that she has made such a mistake. 她犯了这样一个错误, 真是遗憾。 这样就构成了下面一些常用句型: 1) It is + adj. / n. +从句
It is a pity/shame that... 遗憾的是…… It is possible that... 很可能…… It is unlikely that... 不可能…… 2) It +不及物动词+从句
It seems/appears that... 似乎…… It happened that... 碰巧…… 3) It + be +过去分词+从句
It is said that... 据说…… It is known to all that... 众所周知…… It is reported that... 据报道……
It is believed that...据信……;人们相信…… It is suggested that... 有人建议……
It must be pointed out that...必须指出…… It has been proved that... 已证明…….
如: It is believed that at least a score of buildings were damaged or destroyed. 据信, 至少有二十座楼房遭到破坏或彻底毁掉。
5)用于It is important / natural / necessary / impossible that...句型中, 主语从句应使用虚拟语气, 谓语动词用\\“should + 动词原形\\”的形式, should有时有感情色彩。 经典试题

My Country – Canada
Contrary to people’s belief , e do not live in snow-covered houses far from civilization. Most of us live in cities that do not seem , at first glance, to differ greatly from those to the south of us. A newcomer in the US quickly learns to cover up his origins and become an American. A newcomer to Canada manages to keep something of the culture and custom of his own background.
Traditionally, the stranger has thought of Canada as a mountainous, snow-swept land of Indians and Eskimos. It comes as a surprise to many to learn that there are hundreds of thousands of us who have never seen an Eskimos, and some who have not seen an Indian or a mountain. Most of us , as I have said , are city people.
Certainly it can get very cold in Canada. Few non-Canadians understand that it can also get very hot. The eastern cities suffer from great heat in the wet July and August, and people actually die each year from the heat. But, of course, we Canadians also know what it is like to be cold. In 1947, it was so cold that a basin of water thrown into the air fell to the ground as ice.
When temperature is concerned, we are a country of extremes ; and yet as a people, we tend to be mild .Non-Canadians like to mix us together with our American neighbors, but we are not really like the American. Our environment, our social attitudes and our history make us a different kind of North American. The differences may not be easy for the newcomer to understand, but they are very real to us.
Our history is not very bloody. We are, after all the only people in all the Americas who did not separate violently from Europe. We were slow to give up our colonial ties to England. Another thing that make us different in the Americas is that our bilingual and bicultural makeup. Visitors are often impressed by the “foreignness” of Quebec City, with its twisting streets and its French-style coking.
I a not suggesting Canadians are anti-American. We watch American television programs. We read American magazines and American best-selling novels. We tend to prefer American-made cars over European and Asian ones. We welcome American tourists every year. But, the only thing we are really sure of is that we are not Americans.
