3.
Mother，Mrs. Green，lived with her daughter and her son in a big city. She was already in her seventies. Every morning after breakfast she went for a walk in the park and came home at half past twelve for her lunch.
But on morning a police car stopped outside their house. Two policemen helped Mr. Green to get off the car. One of them said to her son，“The weak woman lost her way. So we sent a car to bring her home.” Her son was very surprised， but he thanked the policemen.
“Mother，you have been to that park every day for twenty years. How did you lose your way there？” Her son asked.
Mother said with a smile，“I didn’t lost my way at all. I just got tired and I didn’t want to walk home！
根據(jù)短文判斷正誤，正確的寫“T’，錯誤的寫“F”
( ) 1.Mrs Green lived with her children those days.
( ) 2.She was just seventy years old.
( ) 3.The police droved Mrs. Green home because she didn’t want to walk home.
( ) 4.Her son thought she really lost the way.
( ) 5.She has been to the park every day since twenty years ago.
分析 1.T.文中講的是她和她的女兒和兒子一起住，因此是對的.2.F.因為文中講她有七十幾歲，而不是正好七十歲，所以錯了，3.F.因為她告訴警察說她迷路了，警察送她回來的，而不是因為她不想走，警察才送她的.4.T.因為她兒子問她是怎么迷路的.所以是對的.5.T.她兒子說二十年來她天天去公園，所以是對的.
4.Where’s Jim？He to the cinema.
A have been B has been C. have gone D. has gone
解析 選D，從主語 he得知應(yīng)用has而不是 have因而不會是 A和C，又從 Where’s Jim？得知Jim不在這兒因而不用been，所以只能選D.
5.We must make a contribution to the environment.
A improving B improve C protect D protected
解析 選A。因為 make a contribution to后只能接名詞，代詞或名詞性短語和詞組，而 B、C、D都不能，只有A可以構(gòu)成動名詞短誤因此選A
6.Sorry，kept you .
A. stand B. wait C. to stand D. waiting
解析 選D.因為“keep + 賓語 + 賓補”中，賓補要是形容詞，介詞短語和動名詞等表示“讓…處于某處或某種狀態(tài)”而不能直接用動詞或不定式，所以選D.

常見問題8: Make our world more beautiful 8
問題：
Lucy and Lily can speak good Chinese, because they _______ China for six years. (山西省1999年中考題)
A．have been in B．have been to
C．have come to D．have gone to
解答:
分析 現(xiàn)在完成時的另一種用法，表示過去已經(jīng)開始，持續(xù)到現(xiàn)在的動作或狀態(tài)，甚至還可能持續(xù)下去，常與for和since連用。
(1)for和since都可以表示一段時間，與現(xiàn)在完成時連用。for可以和表示一段時間的時間狀語連用，如：for three days(三天了)。since與表示某一具體時間的時間點連用，如：since 1980(自從1980年以來)，since three years ago(自從三年前)。
(2)用since或for表示的時間狀語，其句中的謂語動詞要用延續(xù)性動詞。在現(xiàn)在完成時態(tài)里，如果要把瞬間動詞和表示一段時間的詞或短語連用，則需把瞬間動詞換成近義的延續(xù)性動詞，如come換成be here。
答案 A
注意! 此題容易忽略介詞for而選B。把瞬間動詞換成近義的延續(xù)性動詞有：
die→be dead; buy→have; join the league →be a league member; leave→ be away; begin/start→ be on; come→be here; borrow→ keep ; fall asleep→be asleep; finish/end →be over; open→be open; close→be closed.
常見問題9: Make our world more beautiful 9
問題：
The room is very clean. You don’t need _______ it.
A．clean B．to clean C．cleaning D．cleaned
解答:
分析 need有兩種用法。一種為實義動詞，其用法是need to do，否定形式為don’t need to do。另一種為助動詞，其用法是need do，否定形式為needn’t do。此句用實義動詞，后接名詞或不定式。
選項A、C、D與上述詞組不符。
答案B
注意! need的兩種用法容易混淆。應(yīng)記住need為情態(tài)動詞時，與can，may等詞一樣，后面要接動詞原形。謹記這一點，就容易分清need do與need to do的用法。
