So, what did you think of the meeting?
"What did you think of" is used to ask someone for their opinion about a past event. Please remember that "how did you think of...?" can NOT be used in the same way as "what did you think of...?".
Other examples are:
What did you think of last night's game?
What did you think of Mr. Shimizu's speech?
"How about" + (verb + ing) is used to make a suggestion.
Other examples are:
How about going to see a movie tonight?
How about taking a taxi home?
Is Italian food very popular in your country?
If something is "popular" it means that a lot of people like it.
For example:
Baseball is very popular in Japan, but cricket isn't.
My wife and I used to eat out a lot.
"used" + infinitive is used to talk about something that was done often in the past, but not now.
Other examples are:
When I was a child, I used to watch "Doraemon" on TV.
Japanese people used to wear kimono every day, but now they wear mainly Western clothes.
People used to communicate by telex, however now they send faxes and e-mail.
When a date in the future has been set for something to happen, we say that it is "due". In this case, Mr. Ishida's wife is pregnant, so Mr. Clinton wants to know when the baby will be born.
Other examples are:
My report is due next Friday, I have to give it to my boss.
The baby is due at the end of March.
I'm due to start my new job on Monday.
This is a short way of saying "middle of". It can be used with the names of months and years.
Other examples are:
Next term is due to begin mid-April.
We're planning to have a conference mid-1999.
