二、学海导航
【学法指要】
单元重点词汇点拨
1.fly苍蝇
This kind of disease is caused by flies .
〖点拨〗fly作动词的常见搭配有：fly nonstop from Shanghai to New York从上海直飞纽约。fly a kite放风筝。fly from从……逃亡。fly at攻击（不用被动语态）。let fly (at) 射击
2. absence不在；缺席
His absence from school was caused by illness . 他缺课是因为生病。
〖点拨〗absence为不可数名词，但是，在表达“一次缺席或者不在”时是可数名词。如：He made up a wonderful story to explain his several absences .
He returned after an absence of twenty minutes .
注意：absence的形容词是absent 。常见搭配有：during one’s absence某人不在时。be absent from school ( work , home ) 没上学（不上班，不在家）。
3. truth真相；实际情况
The whole truth has come out . 真相已水落石出。
〖点拨〗truth to tell you = to tell (you ) the truth说真的。这是个固定词组，在句中作状语。如：To tell you the truth , he stole books from the bookstore .
4. charge费用；价钱；索价
What are your charges for the room ? 住房费是多少 ？
The exhibition is open to the public without charge .
〖点拨〗charge sb + 钱 + for sth因……收费……。How much do you charge for …? ……多少钱 ？如：The hotel charged me 50 yuan for a room for the night .
How much do you charge for a haircut ?
5. determine决定；决心
We determine to buy a computer .
〖点拨〗be determined to do = make up one’s mind to do下决心干…… 。
6. permit许可；执照；营业证；允许
You can’t enter the research center without a permit .
〖点拨〗permit sb to do允许某人干……。permit doing允许干……。如：
We don’t permit smoking here .
注意：permit常用在独立主格结构中。如：Time permitting , we’ll have a meeting this evening . = If time permits , …
另外，注意permit的现在分词、过去式和过去分词要双写词尾：permitting , permitted 。
7. prison监狱
She was sentenced to two years in prison . 她被判两年徒刑。
〖点拨〗注意，当prison表示蹲监狱时，其前不用冠词。如：go to prison进监狱。be in prison住监狱。　break prison越狱。
〖误〗She has gone to prison for five months .
〖对〗She has been in prison for five months .
She went to prison five months ago .
8. couple夫妇；一对
They are a newly married couple .
〖点拨〗couple (侧重种类不同)　，　而　pair侧重一套和配对性。the couple作主语时其后的谓语可以用单数，这时把它看成一个整体。另外，a couple of可以表示“几个”。如：
The young couple seems / seem excited .
They keep / raise a couple of dogs . 他们养了几只狗。
单元词组思维运用
１. treat … as , consider … as , regard … as , look on / upon …as , take …as , think of…as 把……当作。如：
