5. 因?yàn)?date from 的意思是“自某時(shí)起存在至今”(＝have existed since)，它通常用于一般現(xiàn)在時(shí)，而不用過去時(shí)態(tài)(盡管其后接的總是表示過去的時(shí)間)。

但若所談?wù)摰臇|西現(xiàn)在已不復(fù)存在，則可用一般過去時(shí)。如：

The church, which dated from the 13th century, was destroyed in an earthquake two years ago.　 那座教堂是13世紀(jì)建成的，兩年前在一次地震中被毀了。

4. 上文說“他”變化很大，即“他”現(xiàn)在不是過去的那個(gè)樣子了，故第一空填is，第二空填 was(其實(shí)第二空也可用 used to be)。

3. 這是由 but I don’t know whether he has finished it 這一句話的語境決定的，全句意為“史密斯先生去年在寫一本書，但我不知道他現(xiàn)在是否寫完了”。有的同學(xué)可能由于受 last year的影響而誤選B。但若選B，則句子前半部分的意思則變?yōu)椤笆访芩瓜壬�去年寫了一本書”，既然是“寫了”，那么這與下文的“但我不知道他現(xiàn)在是否寫完了”相矛盾。

2. 第一空應(yīng)填 look, 因?yàn)檫@是祈使句的謂語；第二空應(yīng)填 had，因?yàn)榍耙痪湔f“看看時(shí)間吧”，這一看當(dāng)然知道了現(xiàn)在很遲的情形，“不知道這么遲了”顯然應(yīng)是“過去”的事，故應(yīng)用一般過去時(shí)態(tài)。

1. 第一個(gè)人說“我忘記他的電話號(hào)碼了”，這個(gè)“忘記”應(yīng)該是現(xiàn)在的情況，即現(xiàn)在忘記了，要不然就沒有必要同對(duì)方說此話了，故第一空應(yīng)填 forget；第二個(gè)人說“我有他的號(hào)碼，但我忘記帶電話本了”，這個(gè)“忘記”應(yīng)該是過去的情況，即過去忘記帶電話本，所以現(xiàn)在電話本不在身上(注意句中的轉(zhuǎn)折連詞 but)，故第二空應(yīng)填 forgot，即答案選應(yīng)C。
