补充：涉及表达时间的介词at, on, in的用法辨析
| 用途 | 举例 | |
| At | 具体时间点 （某时/某时某分） | She has a meeting at 9:40. 她在九点四十的时候有一个会议。 |

| 进餐时间段 (at breakfast/lunch/dinner(supper)) | We had toast and jelly at breakfast. 我们的早餐吃了吐司和果冻。 | |
| On | 具体某天（含星期几） | Come and have dinner with us on Wednesday. 星期三来和我们共进晚餐吧。 I was born on September 29, 1998. 我出生于1998年9月29日。 |
| 具体某天的某部分 | I went to the hospital on the evening of July the first. 七月一日的晚上我去医院了。 I need to send my kids to school on Monday morning. 星期一早上我要送孩子们去上学。 | |

相似辨析：
1. at present & in the present
at present时间状语。意为“当前、目前”。
in the present实际上是in加the present，并非固定词组，就像in the future, in the past。意为“现在”。
2. at night & in the morning
at noon, at night 固定搭配。意为“在正午”，“在晚上”。
in the morning, in the afternoon, in the evening
这里主要是注意at night和in the evening，两种相近意思的不同表达。但in the evening倾向于“在傍晚”。
3. at the beginning of & in the beginning of
at the beginning of 通常与发生一次行为搭配使用。
in the beginning of 通常与发生多次行为搭配使用。
4. at Christmas & on Christmas Day
at侧重指“休假的时节”，而不指具体的哪天。
on侧重指具体的时日，与他连用的短语多含“Day”。
5. 特别需要注意如果时间名词前用this, last, next等修饰时，表示“在某时”的时间短语前，并不需要任何介词。e.g. I will go to school next week.
