英语笔记
1.完整句子应为"It is better to take the subway." 为达到简洁凝练的效果，省略"It is"。
2.to 在这里弱读作/tə/。
3.这里指一种票价，换乘不必要额外购票。
4.don't 后面接辅音，t 不发音。
5.peak hours 指“高峰期”。
英语语音语调
to的弱读
口语中.to在重点强调的情况下读作/tu:/一般情况下读作/tə/;to的后面如果接辅音，还可读作/də/;但当to用在句末
时，读作/tu/。如：
Where are you going to/tu/?
你去哪儿?
It's not easy to/tə/ read all these books one day.
一天内读完这些书不太容易。
Would you like to/tə/ open the door for me?
你能帮我把门打开吗?
Tell me how to/də/ start this program，please.
请告诉我怎样着手展开这项工作。
