三、語法小貼士。
1.ago和before的區別
1) ago為副詞，意為“以前”。“一段時間 + ago”，常用于一般過去時。
e.g. 兩天前我去拜訪他，但是現在他已經去了上海。
i ________ him two days ________, but now he ________ ________ to shanghai.
2) before作副詞，可單獨使用，常與現在完成時或過去時連用。ago則不能單獨使用。
e.g. 我以前從未見過他。 i ________ never ________ him ________.
3) before作介詞，后接某點時間；作連詞，引導時間狀語從句。ago不能作介詞和連詞。
e.g. 他會在5點鐘以前回來。 he will be back ________ five o’clock.
我離家前將給你打電話。 i’ll ring you up ________ i leave home.
2.time的用法
1) time意為“時間”，作不可數名詞。
e.g. 青少年們不應該浪費時間。 teenagers shouldn't waste ________.
2) time意為“時代”，“時期”，作可數名詞。
e.g. 看看在不同時代的交通工具。 look at the transport at different ________.
3) time意為“次”，“回”，作可數名詞。
e.g. 我已經告訴你幾次了。 i have told you about it several ________.
