【答案與解析】

1. C。用現(xiàn)在完成時表示影響，即指現(xiàn)在已經(jīng)作出決定。

2. B。用現(xiàn)在完成時表示影響或結(jié)果，即現(xiàn)在筆不見了，是由于某人已經(jīng)把它拿走了的結(jié)果。

3. D。用現(xiàn)在進(jìn)行時表示現(xiàn)在正在進(jìn)行的動作。

4. A。從下文的語境看，既然現(xiàn)在叫對方重復(fù)一遍，說明“沒聽清對方的最后一點(diǎn)”應(yīng)發(fā)生在過去（即說此話之前）。

5. C。這時用一般過去時表示過去曾經(jīng)是老師，但現(xiàn)在不是了。

6. B。before 用作副詞時不與具體時間連用，泛指“以前”，通常與一般過去時或現(xiàn)在完成時連用。

7. A。由no是對前句的否定可知現(xiàn)在不在部隊(duì)服役，是以前“服過役”，故用一般過去時。

8. A。have been to…去過某地(已回來)，have gone to…到某地去了(沒回來)；又因?yàn)閱柕氖?/FONT>Tom回來之前到去過某地，故用過去完成時態(tài)。
