I am Li Fan,chairman of the Students’ Union.I am writing①to draw your attention to some improper behaviour in our campus:littering and scribbling.It has been making② our school dirty and unpleasant.I always feel③ ashamed whenever I see this.It is clearly not appropriate for a student to litter and scribble about.Last week,the Students’ Union held④ a meeting to seek some solutions to these problems.We were having⑤ a heated discussion when our headmaster came and joined us.After the meeting,the headmaster said that the school had made⑥efforts to improve this situation and more dustbins would be placed⑦ around.Recently,the Students’ Union has set⑧up specific rules against such behaviour.At the same time,all of us should develop good habits and behave ourselves.We believe that,with the joint efforts of both teachers and students,our school will become⑨ a more enjoyable place in the near future.

二、主动形式表示被动意义的几种情况

(3)在need,want,require,deserve,bear 等动词,worth 等形容词的后面,动词-ing形式用主动形式表示被动意义,其含义相当于动词不定式的被动形式。
(4)在某些“主语(人/物)+be+形容词+动词不定式”中,动词不定式的主动形式表示被动意义。这些形容词有nice,easy,fit,hard,difficult,important, impossible,pleasant,interesting等。

这个问题很难解决。(可看作省略了for me)

分析:解本题时要运用语境综合判断法。根据上文“On Mondays and Fridays,she worked at a college giving students guidance so that they could have a good choice of career.On Tuesdays and Thursdays she helped out as a volunteer to give first aid to people without homes.”中的谓语动词可知此处应用一般过去时。
taught
【例2】 In the last 10 years or so,however,Traditional Chinese Medicine (TCM) (get) more popular all over the world.
分析:考查时态。解本题时要运用时间状语判断法。根据时间状语“In the last 10 years or so”可知,本句应用现在完成时。
has got
2.语态图解
【例1】 As the construction goes on,more roads (build) and the metro system will be expanded which can reduce traffic jams.
分析:解本题时要运用主谓关系判断法。根据“the metro system will be expanded”可知此处应用一般将来时。more roads与build之间为被动关系,因此用被动语态。
【例2】 Owing to the vast areas and large population of China,diverse dialects can (find) in this great land,such as the Wu dialect in Shanghai,Hakka and Cantonese.
分析:解本题时要注意句中的情态动词,且dialects与find之间为被动关系,根据“含有情态动词的被动语态”的结构可知答案。
will be built
be found
