Mom looked as pleased as punch when she got your letter!

　　妈妈收到你的来信时特别高兴。

　　这句句子关键是as pleased as punch 这个固定词组的使用呢？它的意思是十分高兴，得意洋洋。可以用在表达人的高兴心情的情境中。如句子You're looking as pleased as Punch this morning.

　　To do your duty is not enough. You must go the extra mile.

　　只做份内之事是不够的，你必须多做一点点。

　　For example: a high school student wants his teacher to write a good recommendation letter for him. His mother suggests that he should participate more in class activities and ask the teacher questions after class.

　　Student: "But mom, I turn in my homework always on time. I am a good student".

　　Mom: "To do your duty is not enough. You must go the extra mile. There are so many students in the class and only by constantly communicating with your teacher will you stand out."

　　妈妈的建议是，除了分内的功课外，学生还得常提问题，和老师沟通，才能让老师对学生更了解，留下更深的印象。

　　I prefer the red one to the black one.

　　我比较喜欢红色的一辆。

　　prefer。..to。..

　　宁可，宁愿(选择);更喜欢[+v-ing][+to-v][+(that)]

　　在小D的（080819）这一期中也用到了prefer这个句型

　　eg:I prefer fishing to swimming. / 比起游泳，我更喜欢钓鱼。

　　prefer这个词已经具有“更”的意思，经常作为比较出现。

　　另外prefer这个词是重读闭音节，因此在现在分词和过去分词时，prefer中最后的“r”要双写，即preferring，preferred

　　Can you give me a wake-up call?

　　你能打电话叫醒我吗？

　　住酒店时的叫醒服务。

　　What time am I supposed to check in?

　　我应该什么时候去办登机手续？

　　使用情况：酒店，飞机，轮船等，一般在入住和上某大型交通工具时使用。

　　语法：被动语态，基本机构为：I am supposed to check in what time(when)。

　　suppose:设想，猜测，认为。

　　如：I suppose you are right. 我认为你是对的。

　　所以原句中 be supposed 为 I 被认为，假定，意思为“你们认为我应该。..”

　　原句中省略的是“对方”，即需要 check 的那一方。

　　句子结构为what time 引导的特殊疑问句，将时间状语提前，be动词置于主语I之前。

　　Bob has always had a crush on Lucy.

　　鲍伯一直在爱着露茜。

　　Had a crush on sb. 爱着某人。

　　这里的crush应该是迷恋的意思哦。

　　Hold on a minute. I 'll call him.

　　请别挂我去叫他。

　　hold on:

　　1.(informal) used to tell sb to wait or stop

　　例句：Hold on a minute while I get my breath back.

　　2.to survive in a difficult or dangerous situation:

　　They managed to hold on until help arrived.

　　3.(informal) used on the telephone to ask sb to wait until they can talk to the person they want:

　　例句：Can you hold on? I’ll see if he’s here.

　　这里取第三种意思，当你接到电话时，对方要找的人不是你，而是你旁边的人（在家里时家人或者办公室同事），你会说Hold on a minute. I 'll call him.
