  四、难点句型解析和知识点
  1. you are supposed to shake hands.
  【解析】be supposed to do… 应该……被期望做……,当句子的主语是人时,它可以用来表示劝告,
  建议,义务,责任等,意思是 "to be expected to do sth."or "to have to do sth."
  e.g. you’re supposed to ask the teacher if you want to leave the classroom.
  如果你要离开教室,应该先问问老师。
  we are not to supposed to play football on sunday.
  不准我们在星期日踢足球。
  2. that’s how people in japan are expected to greet each other.
  greet =to welcome or say "hello" 动词 "问候,打招呼"

  他向她打招呼说 "早上好"。
  she greeted me with a friendly smile. 她向我微笑致意。
  3. where i’m from, we are pretty relaxed about time.
  【解析1】where i’m from是一个由 "where" 引导的地点状语从句。
  e.g. just stay where you are. 就留在你原来的地方。
  【解析2】relaxed adj. 放松的,自在的 (人做主语;如果事或物做主语,用relaxing)
  be relaxed about…对…感到放松
  e.g. don’t be afraid, just be relaxed about the interview.不要害怕,轻松面试。

  你只要放松地面对考试就可以了。
  4. we value the time we spend with our family and friends in our everyday lives.

  【解析1】drop by 顺便拜访,
  e.g. drop by my home this evening .今晚到我家来谈谈。
  i have to drop by the bank to get some money. 我得到银行去取一下钱.
  6. we’re the capital of clocks and watches, after all!
  【解析1】after all 毕竟
  e.g. so you see, i was right after all. 你看, 毕竟还是我对吧。
  you decided to come after all. 你毕竟还是决定来了。
  7. so i make an effort to be on time when i meet my friends.
  【解析1】make an effort[ˈefət] to do sth 做出努力去做某事
  e.g. i will make an effort to stop smoking. 我要尽力戒烟。
  you should make an effort to improve your reading ability.
  你应该努力提高你的阅读能力.
  8. also, we never visit a friend’s house without calling first.

  e.g. you will hardly ever be able to speak good english?
  without practicing.
  你不练习几乎是不可能把英语学好的。
  seldom, hardly
  【活学活用】
  1. — how nice the music sounds!
  — it does! the peaceful music will make you feel _______.
  a. excited b. bored
  c. moved d. relaxed
  【解析】relaxed作形容词,"放松的、宽松的、轻松自在的",可作表语、定语或宾语补足语。
  作表语时,主语常为人。
  2. people in colombia needn’t make plans to meet their friends. they often just drop by their homes.
  a. give a ride to b. give up visiting

  我在尽我一切所能使他们感到宾至如归。
  10. you wouldn’t believe how quickly my french has improved because of that.
  【解析1】you wouldn’t believe …是一个常用句式,相当于汉语所说的"你无法想象……;你想都
  想不到……;你绝不会相信……",表示所陈述的事情超出想象之外。与此类似的表达还有
  you would never believe…或you would hardly believe…。eg:
  you wouldn’t believe that he found his long-lost sister in taiwan!
  你绝对想不到他在台湾找到了失散多年的姐姐!
  you would never believe what quick progress he’s made ever since he attended your class.
  你根本无法想象,自从他听了您的讲课后进步有多大。
  11. my biggest challenge is learning how to behave at the dinner table.
  【解析1】learning how to behave at the table是现在分词短语,在此用作句子的表语。eg:
  his main hobby is fishing. 他的主要爱好是钓鱼。
  the most important thing is getting there in time. 最重要的事是及时到达那里。
  【解析2】behave -- un. behavior
  behave是不及物动词,意为"表现;行为",behave well / badly表示"表现好/糟糕"。
  behaviour ( 举止;行为),是不可数名词u.n.
  【活学活用】请根据汉语意思补全英语句子,每空一词。
  (1) 如果你那样表现,你会让人厌恶的。
  ____ you _______ like that, you’ll get yourself disliked.
  (2) 如此的行为可能招致麻烦。
  ______ ________ may cause trouble.
  12. … but i’m gradually getting used to it.
  【解析1】get used to 习惯于
  e.g. we get used to this way of speaking,.
  我们习惯了这种说话方式。
  【辨析】:
  ① be/get used to sth./doing sth. 习惯于…
  e.g. he got used to living in the country.
  他习惯住在乡下。
  ② used to do sth. 过去常常做某事(现在不做了)
  e.g. he used to plant roses.
  他过去常常种植玫瑰。
  13. another example is that you’re not supposed to eat anything with your hand except
  bread, not even fruit.
  【解析1】except作介词,意为"除……之外",和but意义相似,但语气上要比but更加强烈。
  1) everyone is here except him.
  2) we have classes except saturday and sunday.
  通过观察例句1和例句2,我们可知except后可以跟 ______ 和 ______ 。
  3) i can take a holiday at any time except in september.
  通过观察例句3,可知,except后也可跟__________。
  4) he never came to visit except to borrow something.
  5) he will do anything except lent you money.
  通过观察例句4,可知except后可接动词不定式。意思是"除了做……"。但在例句5中except后为"lend you money",所以我们可知若except前含不定代词时,就要______________________。
  *besides 表示"除了......之外(还有)",其后可接名词、代词、动名词(词组)。
  (besides在例, except 不在例)
  there are some students to be regarded as top students besides you.
  除了你之外还有一些学生被认为是优秀的。
  【活学活用】将下列汉语句子翻译成英语。
  1. 除了烹调,她别的都会干。
  ______________________________
  2. 我除了要通过考试之外,没有别的心愿。
  ____________________________________________
  除了早饭吃两片面包外我还吃一个鸡蛋、一个橘子和一个香蕉。
  ____________________________________________
  answers: 1. she can do everything except cook.
  2. i have no other wish except to pass the examination
  3. i have an egg, an orange, a banana for breakfast besides two pieces of bread.
  14. 我发现要记住每一样事是困难的。
  i find it difficult to remember everything.
  【解析】形式宾语结构:find / think + it/them +形容词 to do sth.
  eg: i think it hard to study english.
  五、grammar
  1. be supposed to do sth.
  意为"(按规定、习惯、安排等)应该做某事,可用来表示劝告、建议、义务、责任等,相当于should的用法。 否定形式为"be not supposed to do sth." 表不该或禁止做的情。
  e.g. if you want to eat ice-cream, you are supposed to ask your mum.
  如果你想吃冰淇淋,应该先问问你妈妈。
  2. be expected to表达"被期许(预期)会做某事, 希望做某事,表示一种可能性。
  e.g. she was expected to arrive before dinner. 希望她晚餐前到达。
  be supposed to do相对于be expected to do主观性更强一些。
  3. it be + adj. +to do sth.
  it be important to do sth. ….做某事很重要。
  it be polite to do sth…做某事有礼貌
  it be impolite to do sth…做某事是不礼貌的。
  e.g. it is important to learn english well. 学好英语很重要。

  2. 写作技巧点拨:

  ②dear jimmy(左起顶格)
  ③i"m glad to receive your letter...(正文,开头空四格)
  ④yours sincerely,
  jack(右下,包括敬语和落款)
  2、官方、正式的书信
  信内应包含收信人地址(西方古时防止信封损坏地址无着而沿用至今的传统)、日期、称呼、正文、落款等。其实官方的书信更多应该参考第3点,越全面越表示你对他们的重视。
  ①12th,peace road, 19th district
  XX12, new york, u.s.a(地址同样顶格写,从小写到大)
  (以下同1)
  ② october,16,XX(右起顶格)

  ⑤ yours sincerely,

  2) 有关文化礼仪的写作常用句型

  it’s important to…
  you should/shouldn"t….
