[[求助与讨论]] few questions of cloze tenses

[复制链接]
发表于 2007-12-4 23:16:53 | 显示全部楼层 |阅读模式
Let me go first, these questions as following will be not difficult but i just
can't easily get the point to distinguish when the situation should use simple
tense or progressive tense. I wonder if someone could help me to establish the
concept of the usage of using the two tenses's the bestest chance?

here's example (use simple and proressive tenses only):

Look. It (begin)________ to rain. Unfortunately, I (have,not)________ my

unbrella with me. Tom is lucky. He (wear)_________ a raincoat.

my answer is...

1.begins but it should be \"is begining.\" i need to know why i can't use
\"begins\" as an answer?

2.(have,not) at here, why it can't be \"haven't\" but it must be \"don't have\" as
its answer?

3.(wear) i don't know why the answer here is \"is wearing\" but isn't wears?

thanks for your answering in advance.

1. is beginning.这里前面有一个look(看,瞧),后面一般接现在进行时,如 Look, he is coming.看,他来了。
2.have这里是实义动词(拥有,携带,etc),不是助动词,否定式自然就是don't have 了
3.wear(穿,戴)一般强调状态,穿着,戴着,所以习惯用进行时,表示状态。
