I also learned useful sentences like “Its a piece of cake” or “It serves you right.” a piece of cake和serves sb. right是英语中的两个习惯用语, 也可称作习语idiom(s)。同汉语中的成语类似, 习语是人们在长期的语言运用中约定俗成的一种固定表达方式, 其意思往往不是字面所表达的含义。如: a piece of cake表示事情非常简单、易于解决, 相当于汉语的“小菜一碟; 小事一桩”; serves sb. right则相当于汉语说某人“活该”。6.

Good learners often connect what they need to learn with something interesting. connect v. 意为“连接；与有联系”当表示把两个物体（A和B）连接起来时，常用结构是connect A to / with / and B，其中to表示把A接到B上，多用来指动作而不指状态。e.g. Connect the speaker to / with the record player, please. The subway connects the train station and / with the airport.3.

Whats important is the experience you gained. 2) whether or not 是英语从句的一个连词结构，意思和功能相当于whether, 表示“是否”，常出现在宾语从句，主语从句中。使用时，也可把whether和or not分开，or not放到句尾。 例如: I cant tell whether or not the teacher likes me. 此句也可以写成: I cant tell whether the teacher likes me or not.8.

(覆水难收） There is no joking about the matter.It is fun playing with children. 和孩子们一起玩真好。 2. 用作宾语1) 作动词的宾语 常见的此类动词有：practise, enjoy, finish, give up, cannot help, keep, keep on, mind, miss, put off, depend on, think about, succeed in, worry about, be used to, get used to, look forward to, pay attention to等。e.g. How do you practice speaking? I have to finish reading a book and give a report.2) 作介词的宾语 1. I learn English by doing grammar exercises.2. Shall we have a rest or get down to doing our work? 3. He was late again because of getting up late.4. Lock the doors and windows before going out. 5. What/How about the two of us playing games？3) 既可接动名词又可接不定式的常用动词有：remember, forget, regret, mean, try等，但表达的意义不同。e.g. I remember seeing her at the hotel. 我记得在宾馆见过她。(动作发生了) I will remember to see her at the hotel. 我记着要去宾馆见她。(动作尚未发生) remember/forget/ regret to do 动作尚未发生 doing动作已经发生try to do 设法、努力去做，尽力doing 试试去做（看有何结果）mean to do 打算做（主语一般是人）doing意味着（主语一般是物）regret to do 对将要做的事抱歉doing 对已经发生的事感到后悔stop to do停下去做另外一件事doing停止做手头的事情3. 作表语 动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。表语动名词与主语通常是对等的关系，表示主语的内容，主语、表语可互换位置。 e.g. Your task is cleaning the windows. 你的任务就是擦窗户。 (Cleaning the windows is your task.) What I hate most is being laughed at. 我最痛恨的就是被别人嘲笑。 (Being laughed at is what I hate most.) 动名词有时态和语态的变化。动名词的时态和语态的基本形式：（以write为例） 时态语态一般时完成时主动语态writing having written 被动语态being written having been written 注意：动名词的否定形式是：not writing 动名词的复合结构：动名词的逻辑主语动名词动名词的复合结构Would you mind _（我开窗户吗）？Would you mind my / me opening the window?my/ me 称为动名词的逻辑主语。I cant understand Jack /Jacks leaving his wife.I cant understand his/him leaving his wife.Jacks/ His leaving his wife is unbelievable.专心-专注-专业
