1. get tired 感到疲劳
When I danced, I felt tired. 当我跳舞时,我感到疲劳。
get tired 意为“劳累”, 其中get 是联系动词,所以tired是形容词作表语。可以和tired搭配的系动词还有be, feel, become等。
Are you feeling tired after such a long walk? 走了这么远的路你感到累吗?
【注意】get/be tired of 与get/be tired 意思不一样,他的意思是对什么产生了厌倦。
I think most of the students are tired of doing their homework. 我想大多数学生都讨厌做家庭作业。
2. It's very easy for me to get tired when I dance. 我跳舞时很容易感觉疲劳。
这句话中的it是形式主语,真正的主语是动词不定式to引导的逻辑主语to get tired。这类句子的常见形式是 it is + adj. + for/of sb. To do sth. ,意为“对于某人来说做某事是。。。的”。其中用for还是用of有一个小窍门: 如果sb.和前面的adj可以用to be来连接的话介词就用of, 如果不能则用for,比如:
It is dangerous for children to swim in the river. 孩子在这条河里游泳很危险。
dangerous危险的,你不能说children are dangerous, 而是这件事dangerous 所以用 for
It was so careless of you to do that. 你那样做真粗心。
Careless 粗心的。你可以说 you are careless, 所以这里用of。
3. Healthy 健康的
Healthy的意思是健康的,可以作表语也可以作定语,所以你可以说 He is healthy, 也可以说 Fish is a healthy dish for you.
保持健康,keep healthy, 也可以说keep fit. 但是fit 只能做表语而不能作定语。所以你可以说 He is fit. 却不能说 Fish is a fit dish for you.
身体状况好你可以说 be in good health, 也可以说be well/healthy/fit
4. Top的用法
top作形容词,意为“一流的、名列前茅的,最高级的,最优秀的,顶级的”。
He came out at the top of the list. 他名列前茅。
Dr Wu is one of the top doctors in our city. 吴医生是我市水平最高的医生之一。
【注意】top 还可意为“顶部,顶部的”。
at the top of the hill 在山顶
on the top shelf 在最上层的架子上
