Language points
1.When I was a tiny baby crying all night, my mom sang to me and stayed by my side.当我还是一个整夜哭闹的小宝宝时,妈妈会给我唱歌,陪伴在我身旁。
【解读】crying all night是动词-ing形式的短语,在名词baby后作定语,起修饰名词的作用。 stay by one’s side意为“在某人身边(给予照顾或支持)”,相当于be at one’s side。
e.g. Do you know the young man waiting outside the school gate
你认识在校门外等待的年轻人吗
Don’t worry. I will always be at your side.
不要担心,我会一直在你身边。
【解读】give sb. a hug意为“拥抱某人”。hug在此处为名词,意为“拥抱;搂抱”。 lift up意为“举起”,lift动词,意为“举起;抬高”。lift sb up把某人举高
【拓展】lift还可作名词,意为“电梯”。
2. When I fell and hurt myself, she gave me a hug and lifted me up.
当我跌倒并伤到自己的时候,她把我扶起来,给我一个拥抱。
e.g. She gave her mother a big hug.
她热情地拥抱了她的妈妈。
When he saw his little daughter, he lifted her up happily.
当他看到他的小女儿时,他高兴地把她举起来。
【解读】 thinking back to those times是动词-ing形式短语作伴随状语。times在这里意为“时光,岁月,时代”。 think back to sth.意为“回想起某事;追忆某事”。
3. Now I’m an adult, thinking back to those times.
现在我已长大成人,回想起那过去的岁月。
e.g. My grandpa often thinks back to his youth.
我爷爷常常回想起他年轻的时候。
I think back to the day I first met you.
我回想起初次见你的那一天。
【解读】 regret 动词,意为“遗憾,后悔”。
regret doing sth.意为“后悔做了某事”,表示对做过的事情感到后悔。
regret to do sth.意为“遗憾地去做某事”,指对要做的事感到遗憾,强调事情未做。
4. I regret talking back, not listening to Mom.
我后悔顶嘴,不听妈妈的话。
e.g. I regret taking his advice at that time.
我后悔那时接受了他的建议。
I regret to say you failed in the exam.
我遗憾地说你考试不及格。
【拓展】 类似用法的动词还有
forget to do 忘记要去做某事 forget doing 忘记做过某事
remember to do 记得还没做的事情 remember doing 记得已经做过的事情
try to do 尽力做某事 try doing 尝试做某事
stop doing sth. 停止做某事 stop to do sth. 停下来去做别的事
