強調(diào)句通常用的句式：it is +?被強調(diào)的部分?+ that +?句子的其余成分。強調(diào)部分指人的時候，用who?或者that;?指物的時候用that。

例1：

It is from?the sun?that?we get light and heat.

? ? ? ? ? ?被強調(diào)的部分（物）

例2：

It was?Sam?who?knocked down that old man and fled.

? ? ? ?被強調(diào)的部分（人）

注意：如何判斷強調(diào)句式？

把一個句子中的it is …that/who這個部分去掉，如果剩余的句子仍然是完整的，那么這個句式就是一個強調(diào)句。反之則有可能是其他從句。

例如：

It is exciting that we succeeded in launching the satellite.

這個句子雖然也有it is ….that?的結(jié)構(gòu)，但只要把這個結(jié)構(gòu)去掉，就可以發(fā)現(xiàn)：剩下的內(nèi)容不能構(gòu)成完整的句子。所以這不是一個強調(diào)句。在這里It is…that?是不能隨便去掉的，因為這里it?是形式主語。

翻譯示例：

例：______________ （直到他詳細(xì)研究）that the first of the vitamins was identified.

1. 所譯部分為句子的主干，需要強調(diào)句型，表達(dá)方式為it is not until...that

2. 從句為過去時，所以主句中也應(yīng)該是過去時

3. “詳細(xì)地”表達(dá)方式應(yīng)該是in detail。

答案：It was not until he investigated in detail

1. 本題考查的是強調(diào)句式。強調(diào)句式由“it is/was + 被強調(diào)成分+that/who…”構(gòu)成。此題強調(diào)的是時間。

2. 在謂語動詞前加do表示對動作的強調(diào)。and連接兩個并列謂語，其形式應(yīng)一致，故用過去時態(tài)。

3. 此題考查的是強調(diào)句的特殊疑問句形式。it在此作為形式主語，真正的主語是that從句。

4. 此句是一個強調(diào)句。根據(jù)題意“他的朋友不怎么喜歡看電視”可知這并沒有什么可奇怪的，故排除B和C。no后直接加名詞相當(dāng)于not any +名詞，可排除A。故選D。

5. 此題考查的強調(diào)句中含有一個定語從句。Who引導(dǎo)的定語從句修飾被強調(diào)部分the boy，that引導(dǎo)的從句構(gòu)成強調(diào)句中的真正的主語。當(dāng)被強調(diào)部分是人時，可以用that和who來引導(dǎo)從句。

6. 此題考查的強調(diào)句型中包含一個定語從句。Which引導(dǎo)的定語從句，修飾被強調(diào)部分the training，that從句構(gòu)成強調(diào)句中的真正主語。

7. 本題考查的是強調(diào)句式。強調(diào)句式由“it was + 被強調(diào)成分+ who…”構(gòu)成。

8. 本題考查的是強調(diào)句式。強調(diào)句式由“it was + 被強調(diào)成分+that…”構(gòu)成。本句強調(diào)的是時間。

9. 本題考查的是強調(diào)句式。強調(diào)句式由“it was + 被強調(diào)成分+that…”構(gòu)成。本句強調(diào)的是時間。not until…意為“直到……才”。

10. 本題考查的是強調(diào)句式。強調(diào)句式由“it was + 被強調(diào)成分+that…”構(gòu)成。從句的語序仍然用陳述語序。
