what shall we do this weekend?
I have no idea.We _________ have a picnic outside the city.
A.could go to B.shall go to C.had better go to
Did you have any problems in Paris?
Yes,___________ Chinese food like rice,noodles and dumplings.
A.find B.found C.finding D.to find
This is non-smoking area.Haven't you seen the sign?
Sorry,I ______ it.
A.haven't seen B.didn't see
C.B 为什么？怎么没人回答呀？
A、B、A
答案应该是A.C.B。
第一题：用could表示提议。因为回答者have no idea，也还没有安排好做什么，所以提议说“我们可以出去野餐”。shall=will,表示已经安排好；had better go to picnic意为"我们最好出去野餐"，也不符合句义。
第二题：应该选C，应该用动名词finding,而不是不定式to find.完整句子是：i had problem (in) finding Chinese food......
have problem (in) doing sth是固定结构，in 可以省略。
第三题：句意是“问：这里是禁烟区，你没有看见禁烟标志吗？答：对不起，（我刚才）没有看见”。没有看见应该是过去的动作。
1.I have no idea不确定，当然就是可能了A. could go to
2。my problem was finding Chinese food like rice, noodles and dumplings
3.过去没有看过。现在看到了。所以不用A. haven't seen
C D B
1.A could有可以的意思 shall是需做某事,不符合题目中句子的意思 C中的意思是最好去做某事也不对 .只有A是最符合句子要表达的意思.
2.D To find是表目的,你在巴黎遇到什么困难吗?是的,为了找到中国食物,比如大米,面条,饺子.其他选项无此意义.
3.B A是现在完成时,B是一般过去时,通过问题可知：这是无烟区,难道你没看到标志吗?对不起,我刚刚没看见.所以通过判断,只需要用一般过去时就可以了 .
