三道英语填空
1.______ do you play basketball Three times a weeks.
a how often
b how much
c when
d where
2.The ticker is on the floor.Would you please ______ for me
a pick it up
b pick up it
c pick up them
d pick them up
3.What did you see ______
a now
b every
c since 1990
d just now
1 a 2 a 3 d
请写出选这个答案的原因.

1、how often是指多久、频率的,符合句意,从答句说一星期三次可看出.
how much是指多少,一般用于提问多少钱、多少次等
when是指什么时候
where是指在哪里
2、捡起来的搭配是pick sth.up,而根据题中谓语可看出是单数,那么就选 pick it up
3、now是现在的意思,如果问你现在看到什么应该是What do you see?
而题中did是do的过去式,表示动作发生在过去,那么可排除A.而B是指每一个,不符合题意.
C、D的时间都在过去,但是since 1990指自从1990以来看到什么,那么动作应该持续到现在,谓语动词就不能用did,要用原型.只有D答案才符合,是刚刚的意思,指 你刚刚看到了什么?
