一、 定義與講解
一般現在時：表示經常性的事情，經常性的動作或一般性事實。
時間狀語：often 經常，usually通常，always 總是，every每個，sometimes 有時，at …在幾點鐘
只有在第三人稱單數用動詞的“三單變化”，其他用動詞的原形。

1.The last time I ______ to the cinema was two years ago.
A. go B. have gone C. have been D. Went
答案：D 時態(tài)的用法。由 “two years ago”可知此句是一般過去時。排除A、B、C三項。故選D。
2. — Have you ever been to Canada?
Yes, I here last year with my parents.
A. have been B. have gone C. went D. Go
答案：C考查時態(tài)的用法。由時間狀語last year 可推斷出該句為一般過去時態(tài)。排除A、B、D。故選C。
3.I called you, but nobody answered. Where_______ you?
B. are C. was D. were
答案D 考查時態(tài)用法。由前句called和answered可知，打了電話而沒人接，為一般過去時，you為第二人稱。故選D
4.Betty will ring me up when she _______ in Beijing.
B. arrives C. arrived D. will arrive
答案B 考查動詞時態(tài)。時間狀語從句中，如果主句和從句的動作都發(fā)生在將來，從句時態(tài)要用一般現在時表示將來。故選B。
5. I ______my hometown for a long time, I really miss it! A. left B. went away from C. have left D. have been away from
答案D 考查動詞時態(tài)。由for a long time可判定該句為現在完成時。排除A和B；leave為短暫性動詞，不能和表示一段時間的狀語連用;排除C；狀語for a long time表示一段時間，應該與延續(xù)性動詞或表狀態(tài)的詞連用，故選D。
6.—I ______ something wrong just now. May 1 use your eraser? —Of course. Here you are. A. write B. wrote C. am writing
答案：B 考查時態(tài)的用法。句中的時間狀語為just now，“剛才”用一般過去時態(tài)。
7.－Where is John? －He ______ the science lab.
A. has gone to B. has been to C. went to
B.答案：A 考查時態(tài)及動詞的用法。根據句意：他已經去了科學實驗室，表示動作已發(fā)生，用現在完成時，A項表示去了某地，即：人沒在這兒；B項表示曾經去過某地，人又回來了。
