8：50 10：45 3：30 2：58用英文怎么表示？

可求出坐车的时间是1小时30分钟,从而可推算出14：00应离开公园,所以在动物园参观和休息的时间共是3小时15分钟

1,3：00 ---three o'clock --Zero past three
2,5：15 ---five fifteen --- fifteen past five
3,5：30 ----- five thirty---- Half past five
4,10：45-----ten forty-five -----fifteen to eleven

10:10 ten minutes past ten
3:05 five minutes past three
8:30 half past eight
10:45 a quarter to eleven
11:00 eleven o'clock

today is Sunday, I get up at 7 in the morning, eat breakfast 7:15, 7:30 read English, 8:00 10:45 doing homework, I help my mother cook. 12:00 we eat lunch in the afternoon, I and my classmates 2:15 soil zoo. I saw the panda, monkey, tiger and elephant. We go home, we are very happy to play.

7:05：Seven Five、five past seven
8:15：Eight fifteen、a quater past eight
9:30：nine thirty、half past nine
10:45：ten forty-five、a quater to eleven
11:55：eleven fifty-five、five to twelve

直接方法是直接念: 如10:45 ten forty-five,基本同上
更复杂一点的方法是:
首先分30分钟前和30分钟后的:
30分钟前的用past:9:12 twelve past nine o'clock
30分钟后的用to: 10:45 fifteen to eleven (还差15分钟到11点) 一般不用past
外国人一般半小时用half,15分钟用quarter来表示
9:30 half past nine
10:45 a quarter to eleven

70个数除的余数分别是0,1,0,2,0,1,0,2.所以是4个数一循环,第70个余数即为1
（此题可以化简为,每个数除三的余数乘3后等于左右两数除3的余数的和（等于3的倍数的话,即为0）,所以那个循环是有道理的）

twelve to nine,twenty-three past nine,a quarter to eleven,half past eleven

ten fouety-five;nine o'clock; five to five;a quacter past three;half past two; three past seven;eight eighteen;eleven twenty;nine forty;two fifty.
说法不唯一,看具体情况.其中 to表示“不到”； past表示“超过”； quacter表示15分钟； half 表示30分钟.

10：45 a quarter to eleven
9：00 nine o'clock
4:55 five ti five
3:15 a quarter past three
2:30 half past two
7:03 three past seven
8:18 eighteen past eight
11:20 twenty past eleven
9:40 twenty to ten
2:50 ten to three
