介绍:
A：It is a beautiful day.Let us go out for a walk.
B：I would like to，but i feel under the weather.I think i am catching cold.
A:今天天气真好！我们出去走走吧！B：我想去，但我不舒服，我可能感冒了。
under the weather ：身体不舒适，有点小病
表达：今天晚上我感觉不太舒服，我想我要再点睡觉了.
I wanna go to bed early tonight because I feel under the weather.
大家注意 under the weather= physically uncomfortable 所以...use "I feel",not " I am"
A：That is too bad.You had better watch your step then.Acold is no fun.
B：I guess it serves me right.I went out without a coat last night.Anyway,i will stay in the house and rest today .
A：太糟糕了。你最好注意一下。太冷了，一点不好玩。
B：我罪有应得,我昨天出去没带外套。总之，我今天还是呆在家里休息休息
watch your step注意，当心/地铁电梯，台阶处可翻成注意脚下--根据语境不同，意思不同
Serve sb right 活该，罪有应得=get what sb. deserved，用在消极方面
表达：那个法律将会使雇佣儿童的人受到应得的惩罚
me：That law will serve the peoples who employ the children right.
老师：That law will serve right people who use child labor.
当serve后的宾语比较长时，可将right提前，宾语放在right 之后
A：The best cure for a cold is to take it easy.Drink lots of liquids,too
B：I will do that.I do not want to go from bad to worse.I might catch the flu.
A：最好的治疗感冒的方法是休息，多喝水。
B：我会的。我可不想变得更糟，我可能得了流感。
Go from bad to worse 越来越糟
Eg：在乔成为俱乐部总裁后，我们原以为一切会好起来，然而恰恰相反，情况越来越糟.
AfterJoe become the president of club，we thought everything wil be allright. but instead，it went from bad and worse.
恰恰相反：instead更传神
on the contrary/by contrast/contrarily/reversely 都可
