一、根据句意及中文提示写出单词
1. — Mary, you look younger and are full of energy.
— Thanks. I have ______ (得益于) a lot from doing yoga.
2. After the meeting, the ______ (采访者) thanked everyone for sharing their ideas.
3. The volunteers were ______ (培训) strictly to deal with emergencies during the Games.
4. We had to light candles because the power cut left the room in complete ______ (黑暗).
5. Don't click on strange websites or links. They could carry ______ (病毒).

1. benefited；2. interviewer；3. trained；4. darkness；5. viruses

1. 考查现在完成时，结构为have+动词过去分词，“得益于”对应benefit，过去分词为benefited；2. 考查名词，“采访者”对应interviewer；3. 考查一般过去时的被动语态，结构为were+动词过去分词，“培训”对应train，过去分词为trained；4. 考查名词，“黑暗”对应darkness，complete后接名词；5. 考查名词复数，“病毒”对应virus，此处泛指用复数viruses。

二、用所给词的适当形式填空
1. Jack (lose) his ticket of the game just now.
2. They (see) the English film twice.
3. I (just find) the bird in the tree.
4. He (be) a bus driver for several years.
5. We need more time to see how things develop before action (take).
6. you (read) any English novels?
7. —Do you mind me (sit) beside you?
—Sorry, the seat is for my brother.
8. I (collect) over one hundred Chinese stamps since I came to Beijing.
9. I (not finish) my homework yet.
10. The students (study) in this school since they (come) here.

1. lost；2. have seen；3. have just found；4. has been；5. is taken；6. Have; read；7. sitting；8. have collected；9. haven't finished；10. have studied; came

1. 根据时间状语just now（刚才），句子用一般过去时，lose的过去式为lost；2. 根据twice（两次），句子用现在完成时，主语是they，故用have seen；3. 根据just（刚刚），句子用现在完成时，主语是I，故用have just found；4. 根据for several years（好几年），句子用现在完成时，主语是he，故用has been；5. before引导的时间状语从句中，action与take是被动关系，用一般现在时的被动语态，故用is taken；6. 询问是否读过，用现在完成时的一般疑问句，结构为Have + 主语 + 过去分词，故填Have; read；7. mind sb doing sth是固定搭配，意为“介意某人做某事”，故用sitting；8. since引导的时间状语从句（从句用一般过去时），主句用现在完成时，主语是I，故用have collected；9. 根据yet（还，尚未），句子用现在完成时的否定形式，主语是I，故用haven't finished；10. since引导的时间状语从句，主句用现在完成时，主语是the students，故用have studied；从句用一般过去时，故用came。

()1. —Where are the children?
—They to Beijing.

A.have been
B.have gone
C.have left
D.have arrived

B

现在完成时中，have been to表示“去过某地（已返回）”，have gone to表示“去了某地（未返回）”。问句询问孩子们现在的位置，说明他们不在说话地，需用have gone to；leave（离开）、arrive（到达）均不与to直接搭配，排除C、D。因此选B。

()2. —Excuse me. Look at the sign “No Photos”.
—Sorry, I it.

A.don't see
B.didn't see
C.haven't seen
D.won't see

B

根据语境，“没看到标志”是过去发生的动作，应用一般过去时，其否定形式为“didn't + 动词原形”，因此选B。

()3. Aunt Mary for more than two years.

A.has seen the writer of Harry Potter
B.has arrived in New York
C.has been married her husband
D.has joined the Yoga Club

A

句中时间状语“for more than two years”表示时间段，现在完成时中需用延续性动词。B选项arrived、D选项joined为短暂性动词，不能与时间段连用；C选项“be married”后缺少介词to，语法错误；A选项符合语法及时态要求。

()4. —Did you have a happy childhood?
—Yes. I everywhere for fun on my father's bike. I'll never forget the pleasant experiences.

A.was used to taking
B.was used to take
C.used to be taken
D.used to take

C

分析各选项：A项was used to taking意为“习惯于做某事”，表现在的习惯，不符合童年的过去语境；B项was used to take意为“被用来做某事”，语义不符；C项used to be taken意为“过去常常被带去”，符合主语I与动作take的被动关系及童年的过去语境；D项used to take为主动形式，不符合逻辑。
