few questions of cloze tenses
Let me go first, these questions as following will be not difficult but i justcan'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。
