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！
根据短文判断正误，正确的写“T’，错误的写“F”
( ) Green lived with her children those days.
( ) was just seventy years old.
( ) police droved Mrs. Green home because she didn’t want to walk home.
( ) son thought she really lost the way.
( ) has been to the park every day since twenty years ago.
分析 1.T.文中讲的是她和她的女儿和儿子一起住，因此是对的.2.F.因为文中讲她有七十几岁，而不是正好七十岁，所以错了，3.F.因为她告诉警察说她迷路了，警察送她回来的，而不是因为她不想走，警察才送她的.4.T.因为她儿子问她是怎么迷路的.所以是对的.5.T.她儿子说二十年来她天天去公园，所以是对的.
e’s Jim？He to the cinema.
A have been B has been C. have gone D. has gone
解析 选D，从主语 he得知应用has而不是 have因而不会是 A和C，又从 Where’s Jim？得知Jim不在这儿因而不用been，所以只能选D.
must make a contribution to the environment.
A improving B improve C protect D protected
解析 选A。因为 make a contribution to后只能接名词，代词或名词性短语和词组，而 B、C、D都不能，只有A可以构成动名词短误因此选A
y，kept you .
A. stand B. wait C. to stand D. waiting
解析 选D.因为“keep + 宾语 + 宾补”中，宾补要是形容词，介词短语和动名词等表示“让…处于某处或某种状态”而不能直接用动词或不定式，所以选D.

C．have come to D．have gone to
解答:
分析 现在完成时的另一种用法，表示过去已经开始，持续到现在的动作或状态，甚至还可能持续下去，常与for和since连用。
(1)for和since都可以表示一段时间，与现在完成时连用。for可以和表示一段时间的时间状语连用，如：for three days(三天了)。since与表示某一具体时间的时间点连用，如：since 1980(自从1980年以来)，since three years ago(自从三年前)。
(2)用since或for表示的时间状语，其句中的谓语动词要用延续性动词。在现在完成时态里，如果要把瞬间动词和表示一段时间的词或短语连用，则需把瞬间动词换成近义的延续性动词，如come换成be here。
答案 A
注意! 此题容易忽略介词for而选B。把瞬间动词换成近义的延续性动词有：
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.

选项A、C、D与上述词组不符。
答案B
注意! need的两种用法容易混淆。应记住need为情态动词时，与can，may等词一样，后面要接动词原形。谨记这一点，就容易分清need do与need to do的用法。
