教學(xué)建議
Since the dialogue and the text of this unit are about chemistry, the teacher may ask some questions about chemistry or other subjects to lead in the dialogue and then show the students the tolls that are used in the chemistry lab when the text is taught.
And also in order to make the class very lively and interesting the teacher may borrow the tubes which are filled with three kinds of liquids from the chemistry lab and ask them to guess whats in the tubes and then ask them to watch the teacher carefully then do what the teacher .
Does, which is the content of the text. In this case the students may feel very new and they may be interested in English class.
In order not to cause something dangerous to happen, the teacher may fill some white vinegar（白醋, some cooking oil(香油),some alcohol(白酒) in the tubes.
重點(diǎn)詞匯講解
1. first of all means first. 意為首先，第一
First of all, I want to say Im very happy to be here with You.
First of all, we must make a decision.
相關(guān)的詞組：at first which is opposite to at last for the first time 第一次
2．a(chǎn)llow 的用法
allow + noun.
allow sb. to do / not to do sth../sb. is allowed to do
allow +doing
(1) He allowed no noise here.
(2) He allowed his boy to spend the weekend with his friends.
(3) Why did you allow her to smoke here?
(4) We dont allow drinking at school.
3. once 是連詞，作“ 一旦……就……”講。
(1) Once she arrives, we can start.
(2) Once you realize it, you will study hard.
(3) Once seen, it can never be forgotten.只要見過一次就難以忘懷。
注意once 一般和現(xiàn)在時連用。
4.unless是連詞，相當(dāng)于if …… not ……
(1) He will not come unless his homework is finished. == He will come if his homework is finished.
(2)You will be in trouble unless you follow my instruction. == You will not in trouble if you follow my instruction.
unless 和 not …until 的區(qū)別
unless 引導(dǎo)從句時多強(qiáng)調(diào)條件，而not …… until 句型則強(qiáng)調(diào)時間。Unless 連接的主從句的時態(tài)一般是主句是將來時而從句現(xiàn)在時。not …… until 連接的主從句中可以使用多種時態(tài)。
比較：
(1) You will fail in the exam unless you listen to the teacher carefully in class.
(2) We wont start until Bob comes.
(3) He didnt find out what had happened until his wife told him about it.
5. Dont touch anything unless your teacher tells you to do.
在此句末的to后省略了touch。在英語里，有些動詞像hope, like, want, try, need, 助動詞如be able to., be going to之后，為了避免前后重復(fù)，往往只用一個to代表動詞不定式。
(1) You can go with me if youd like to.
(2) You may stay at home if you want to.
(3) I dont want to go there, but hes going to.
6. What about when we leave?

(1) Im ready. What about you?
(2) What about playing football?
(3) What about todays match?
7. make sure后跟了一個省略了that 的從句。當(dāng)表示“ 弄確實(shí)、使確定”意思時， 常用在祈使句中，其后的從句里要用一般現(xiàn)在時。當(dāng)make sure 表示“認(rèn)為、確信”的意思時，其后的從句時態(tài)可視情況而定。
(1) Make sure (that ) you come early tomorrow.
(2) Make sure ( that ) your room is clean.
(3) We made sure you were not coming today.我們認(rèn)為你今天一定不來了。
8.turn off 其反義詞是“turn on
turn up (開大) 其反義詞是turn down (關(guān)小本′文,摘自教~育資源網(wǎng)WWw.cHINEseJY.Com)
9.at the end of / in the end
at the end of 意為“ 在……末，在……盡頭”，既可以表示時間的概念也可以表示空間的概念。而in the end只能表示時間的概念,其后不能接of短語，相當(dāng)于 finally, at last.

(4) --- How many apples do you have?--- None.
none / no one 的比較
none 既可以指代人也可以指代物，強(qiáng)調(diào)數(shù)量，可以用來回答how many 開頭的問句。而用法與意思基本相同的no one ( nobody) 只能指代人，它們不強(qiáng)調(diào)數(shù)量，可以用來回答who開頭的問句。
(1) ---- How many people can you see in the picture? ----- None. (一個也沒有 )
(2)---Who is in the classroom? ---- No one. (Nobody) （沒有人）
15. enough 的用法
enough + noun./adj. / adv + enough
