Ⅱ. 交際英語：
人人都希望自己身體健康，工作順利，生活愉快。人體就像一部機器，機器需要經(jīng)常保養(yǎng)才能不停地正常運轉，不出故障；人也需要營養(yǎng)合理的飲食、充足的睡眠、必不可少的休息與娛樂。倘若你為了省錢省時間而終日湊合著吃東西；倘若你為了擠出更多的時間對付艱苦的學習而擠掉了睡眠時間；倘若你為了多打工賺錢，幾乎舍棄了所有的休息與娛樂。那么，生病就在所難免。萬一人生了病就需要去醫(yī)院診斷出出故障的原因，這時就需要和醫(yī)生打交道，下面是常用到的語句。
醫(yī)生用語：
1. What can I do for you ? / What was the matter ? / What\'s the trouble ?

病人用語：
1. I\'ve got a pain ( cough , headache , toothache ) . / I don\'t feel well . / There\'s something wrong with … . / This place hurts . / I feel a great pain here . / I feel dizzy (頭暈) . / I took some medicine last night , but they didn\'t help . / Doctor , please give me an examination .

5. I\'ve been losing sleep . / My whole body feels weak . / I\'ve lost my voice . / My ears are ringing , and my cheeks burning . / I feel a pain in my left leg .

【指點迷津】
單元重點詞匯點撥
1. contain 作及物動詞是“包含；包括；能容納，能裝入”
Sea water contains salt .
This auditorium will contain 3,000 people .
〖點撥〗(1) contain 和 include 雖然都有“包含”的意思，但 contain 可用于表示包含所含之物的全部或部分，而 include 則只是包含一部分。試對比：

The parcel included a dictionary . 那包裹里也包括了一本字典。
The tour includes a visit to Paris . 這次旅行包括游覽巴黎。
The basket contains a variety of fruits . 這籃子裝有各種水果。
(2) including 可以作介詞連接介詞短語。試比較：
Many women were waiting to buy that kind of cloth , including my mother .
Many women were waiting to buy that kind of cloth , my mother included .
可以這樣說，include 著重“被包含者只是整體中的一部分”。contain 著重“內有”。
2. advise 作及物動詞是“忠告、勸告、建議”
The doctor advised a soft diet . 醫(yī)生建議進軟食。
〖點撥〗(1) advise + doing
He advised getting plenty of sleep and eating good meals .
(2) advise sb to do 建議某人干……。advise sb not to do sth = advise sb against doing 建議某人不要干
The teacher advised us not to read carelessly . = The teacher advised us against careless reading .
對比：The teacher advised our reading carefully . (動名詞復合結構)
(3) advise that + 主語 + (should) do

（對）Sharon suggested / advised that I should ask Dr Yang for help .
（對）Sharon suggested / advised my asking Dr Yang for help .
（對）I was advised to ask Dr Yang for help by Sharon .

〖點撥〗(1) scores of 許多，大批

Three score of them are League members .
Three score of those eggs are his .
She has two score (of) eggs . (這種情況下不用 of )
4. discuss 作及物動詞是“討論，議論”。名詞形式是 discussion 。
I\'ve something of great importance to discuss with you .
After careful discussion the two parties reached an agreement on this matter .
〖點撥〗(1) discuss 后直接接名詞、疑問詞 + to do ，不接 about / on 。但discussion 后可以接about 。

（對）We have had a discussion about the problem .
(2) discuss sth with sb 和某人討論……

〖點撥〗(1) 含有suggestion 的主語從句、表語從句、同位語從句、定語從句中主句謂語用 should 型虛擬式。
We agree to his suggestion that the book (should) be published once more .
(2) suggestion 的搭配有：make a helpful / timely suggestion 作出有益（適時）的建議。act on / at one\'s suggestion = act on / at the suggestion of sb 按照某人的建議做。
(3) suggestion , advice 和 opinion
advice 多指根據(jù)自己的學識和經(jīng)驗提出來的供人參考的意見。suggestion 指為改進工作、解決問題而提出的建議，比 advice 委婉。opinion 是日常用語，指對某事的觀點、想法。另外，advice 是不可數(shù)名詞。
Advice is seldom welcome . (諺語) 忠言逆耳。
In our opinion , these trees must be cut down at once .
We have decided to pay more attention to their suggestions .
