這次，朗閣暑假班介紹英語中的插入語(Parenthesis)是插在句子中的一個詞，短語或從句，通常被逗號、破折號或句子的其他部分隔開，它與句子的其他部分之間沒有語法上的關係，因此有的語法學家將其歸為獨立成分。
插入語在句中通常是對一句話的一些附加解釋，說明或總結;有時表示說話者的態度和看法;有時起強調的作用;有時是為了引起對方的注意;還可以起轉移話題或說明事由的作用;也可以承上啟下，使句子與前面的語句銜接的更緊密一些。
...
插入語大致可分為以下10種類型：
1. 形容詞或形容詞短語作插入語
如：worst still, sure enough, strange, most important of all等.
Strange, there is nobody in the classroom.很奇怪,教室里沒人.
2. 副詞或副詞短語作插入語
如：personally, honestly, fortunately, luckily, for us, though, besides, exactly, surely, frankly, still otherwise 等.
Luckily for you, I happen to have the key.你很運氣,我正好帶了鑰匙.
3. 介詞短語作插入語
如：of course, in short, as a matter of fact, by the way, on the other hand, in my opinion, in conclusion等.
In short, we should not stop halfway.簡言之,我們不能半途而廢.
As a result, they suffered heavy losses.結果,他們受到了嚴重損失.
On the contrary, we should strengthen our ties with them.相反,我們還應加強和他們的聯繫.
4. 現在分詞短語作插入語
如：generally speaking, judging from/ by …, talking of…, considering…等.

Frankly speaking, I don」t like the job.坦率地說,我不喜歡這份工作.

5. 過去分詞短語作插入語

注意：之所以稱它為插入語,是由於這種過去分詞是獨立的,沒有邏輯主語.
6. 動詞不定式作插入語

To be frank, I don」t quite agree with you.坦率地說,我不太同意你的意見.

All in all, her condition is greatly improved.總的來說,她的情況有很大好轉.
8. 從句
如：if so / not / any, if I may say so, if you don」t mind, as you know, as you say 等.
If I may say so, we know nothing about it.正如我所說的,我們對它一無所知.

10. 用標點符號引導插入語
如：He was (strange as it seems)an excellent sportsman.他(儘管還顯得令人不解)是個出色的運動員.
