I’ ll never forget the day_____ the great scientist came to our school and gave us a speech.
the morning of March 31, she made an important decision in her life.
— I’m afraid I can’t you, sir. Can you speak more slowly? — Of course.
—How are you going to spend this weekend? — the weather is fine, we’ll climb Mount Tai.
of the students in my school are girls.
— The dictionary is a useful for understanding new words. — I think so.
