时间介词，“吉祥三宝” 第2篇
三个常用介词at, in, on的用法：
巩固练习：
根据句意，用at， in或on填空。
1. Miss Scott arrived in China ____ 5:00 ____ March 7.
2. There will be a meeting ____ Friday afternoon.
3. She was born ____ May 25, 1996.
4. My sister gets up ____ seven thirty ____ Sunday morning.
5. I usually go to school ____ about 7:20 ____ the morning.
Keys:
1.at, on（在这一句中，5：00是钟点，在钟点前面我们用介词at。 March 7是三月七号的意思，在英语中具体的日子前面用介词on。）
2.on（做这道题时有的同学受了in the afternoon的影响，用了介词in，但是他却忽略了afternoon前面的Friday“星期五”，在英语中只要有星期几，就要用介词on。)
3.on（这道题出现了具体的日子，所以我们用介词on。）
4.at, on(seven thirty是钟点，表示在几点用介词at； Sunday morning中由于有了Sunday这个表示星期几的单词，所以我们用介词on。)
