试一试: Maya: What time is it? Ethan: The clock is at 8:00. ___ eight o'clock. 补全 Ethan 的回答。 (It's / It has / There is) 答案: It's — 说时间时用 It's 开头：It's eight o'clock。"It has" 和 "There is" 都不是说时间的说法。
seven-thirty = 7:30（七点半）
说分钟时，只要把钟上的两个数字说出来就行。It's + 小时 + -thirty 表示 :30。
It's seven-thirty. (7:30)
It's nine-thirty. (9:30)
The class starts at six-thirty. (6:30)
Not "It's thirty-seven. (for 7:30)" — say "It's seven-thirty. (7:30)". 先说小时，再说分钟：seven-thirty，不是 thirty-seven。
试一试: Ethan: Is the class over? Maya: Not yet. The clock is at 4:30. It's ___. 补全 Maya 的回答。 (four-thirty / thirty-four / four-thirteen) 答案: four-thirty — 先说小时，再说分钟，所以 4:30 是 four-thirty。"Thirty-four" 把顺序弄反了，"four-thirteen" 是 4:13。
seven-fifteen = 7:15（七点十五分）
:15 也是同样的说法。It's + 小时 + -fifteen 表示 :15。
It's seven-fifteen. (7:15)
It's two-fifteen. (2:15)
The bus leaves at ten-fifteen. (10:15)
试一试: Maya: Is the desk open? Ethan: Yes. The clock is at 8:15. It's ___. 补全 Ethan 的回答。 (eight-fifteen / fifteen-eight / eight-fifty) 答案: eight-fifteen — 小时是 eight，分钟是 fifteen，所以 8:15 是 eight-fifteen。"Eight-fifty" 是 8:50。
a quarter after, a quarter to（过一刻，差一刻）
十五分钟是一个小时的 a quarter（四分之一）。:15 说 a quarter after，:45 说 a quarter to 加上 下一个 小时。
It's a quarter after seven. (7:15)
It's a quarter to eight. (7:45)
It's a quarter to three. (2:45)
Not "It's a quarter to seven. (for 7:45)" — say "It's a quarter to eight. (7:45)". A quarter to 算的是还差几分钟，所以说的是 下一个 小时：7:45 是 a quarter to eight。
试一试: Ethan: Are we late for the six o'clock class? Maya: No, not yet. The clock is at 5:45. It's a quarter ___ six. 补全 Maya 的回答。 (to / after / at) 答案: to — 5:45 还没到六点，所以是 a quarter to six。"After" 用于已经过了整点的时间，而 "at" 放在时间前面，不放在 "a quarter" 和钟点之间。
试一试: Ethan: The sun is high and everyone is hungry. The clock is at 12:00. Maya: Then it is ___. Time to eat. 补全 Maya 的回答。 (noon / midnight / o'clock) 答案: noon — 太阳还在天上，所以这个 12:00 是白天正中间的那个，也就是 noon。Midnight 是夜里的 12:00。
问时间
问时间时说 What time is it?，也可以说 What's the time?
What time is it? It's four-thirty.
What's the time? It's a quarter after six.
Excuse me, what time is it?
试一试: Ethan: ___ Maya: It's eight-thirty. 选出 Ethan 的问题。 (What time is it? / How time is it? / What is time?) 答案: What time is it? — Maya 回答的是一个钟点，所以 Ethan 问的是 What time is it? "How time is it" 用错了疑问词，而 "What is time" 问的是“时间”这个概念，不是钟表上的几点。
试一试: Maya: Is the center open yet? Ethan: The doors are open now. The clock is at 9:00, so it's nine ___. 补全 Ethan 的回答。 (o'clock / thirty / fifteen) 答案: o'clock — 分钟是零，所以 9:00 就是 nine o'clock。"Nine-thirty" 是 9:30，"nine-fifteen" 是 9:15。
常见错误有哪些？

It's thirty-seven. (for 7:30)
It's seven-thirty. (7:30)
先说小时，再说分钟：seven-thirty，不是 thirty-seven。
It's a quarter to seven. (for 7:45)
It's a quarter to eight. (7:45)
A quarter to 算的是还差几分钟，所以说的是 下一个 小时：7:45 是 a quarter to eight。
