But it was not at all so fine yesterday .

Because it rained last night .
neutral
assistant
Did it ?
neutral

It sure did . It was a heavy storm , with lots of thunder .
neutral
assistant
I was fast asleep , and didn't hear a thing .
neutral
user
Well , it may rain again later today .
neutral
assistant
Maybe . I see some dark clouds moving in .
neutral
user
There may also be a strong wind coming in .
neutral
assistant
It'll be dusty , too , I guess .
neutral
user
Maybe not . Dust is no longer a big problem in Beijing .
neutral
assistant
Why is that ?
neutral
user
We've been planting trees for many years .
neutral
assistant
I see . The fall in Beijing is really beautiful .
neutral
user
But the summer isn't . It's scorching in the summer .
neutral
assistant
Then what about spring ?
neutral
user
Spring is warm and short in Beijing .
neutral
assistant
It must be cold in the winter , though .
neutral
user
You got it . Oh , by the way , it may be really cool in the evening around this time of the year . Don't forget to put on more clothes , or you might catch a cold .
neutral
