高二英語Satellites教案

老師要求學生們用圓規(guī)畫圓。

他在商界是知名人士而且也有很多朋友。
the moon circles the earth every 28days . 月亮每28天繞地球一圈。

6.it is possible to say not only what the weather is like at present , but also what is likely to happen in the next day or two .
因此,它不僅可以報告當前的天氣情況,而且可以預報未來一兩天內(nèi)天氣可能會發(fā)生的情況。
a)it is possible to say…是一個由it作形式主語的句子,真正的主語是不定式to say…,隨后的兩個what-clause都是不定式to say的賓語從句,由not only…but also (不僅……而且……)連接。
b)what is likely to happen…中的likely為表語形容詞,意思是“很可能的”,后面常跟不定式短語,其結(jié)構是:be likely to do sth。例如:
tom is likely to win the game . 湯姆很可能會獲勝。
the volcano is likely to break out . 這座火山可能會爆發(fā)。
he is not likely to do it by himself . 他不大可能獨自做這件事。
c)句中的介詞短語at present意思是“現(xiàn)在”,“目前”,相當于now一詞。例如:
i don’t need any help at present . 我目前還不需要任何幫助。
we’re getting along quite well at present . 我們目前相處得還不錯。
需要注意的是present一詞,它既可作形容詞(在場的,出席的),又可作名詞(禮物)和動詞(介紹,引見,贈予),但作動詞時的讀音則為 [pri’zent]。例如:
were you present at the meeting yesterday ? 你出席昨天的會議了嗎?
most of the people present were for the decision . 大多數(shù)在場 的人都贊成這一決定。(當present一詞作定語時,放在被修飾的名詞之后,而不能放在其前面。)
i got a lot of presents on my birthday . 在我生日那天我收到了許多禮物。
the book was a present from my brother . 這本書是哥哥贈送給我的。
they presented a sum of money to the school where they studied years ago .
他們向多年前曾經(jīng)就讀的學校贈送了一筆款項。
allow me to present my friend to you . 請允許我把我的朋友介紹給你。
7.ships and planes can be warned so that they can keep out of the path of the hurricane .
可以給船只和飛機發(fā)出警報,使它們能夠避開颶風經(jīng)過的路線。
此句中的短語動詞keep out of意為“不牽涉進去”,“不要惹事”,“避開”(stay away from something bad)。例如:
children are warned to keep out of the water . 警告孩子們離開水域。
do keep out of the rain if you haven’t a raincoat . 沒帶雨衣那就避一下雨。
mother asked bill to keep out of trouble while she was away .
