高一英語上冊課堂導學復習教案
2.when we use metals,it is important to know how they react with different substances,for example,water and oxygen.
使用金屬時,要了解金屬和不同的物質,例如,水和氧氣,如何發生反應,這一點很重要。
剖析:it是形式主語,to know how...是真正的主語。react with...意為“與……反應”。
3.the reaction of metals with these substances can be put in order.
金屬與這些物質的反應程度可以按順序排列起來。
剖析:put...into order 用……順序進行排列。
4.here is a table with the metals that react most at the top,and the metals that react least at the bottom.
這里有一個表格。金屬反應強的在上面,弱的在底部。
剖析:here is...是一個完全倒裝結構。用來引出想介紹的內容；with the metals that react most at the top,and the metals that react least at the bottom.是一個with+名詞+介詞短語作補足語的獨立主格結構,作后置定語；that react most和that react least是兩個定語從句各自修飾metals。
5.below is a description of a simple scientific experiment.
下面敘述的是一個簡單的科學實驗。
剖析:below is...也是一個完全倒裝句式,用來引出即將介紹的內容。
6.the science facilities are very good,with laboratories that have all the latest equipment.
這些科研設備非常好,實驗室配有最新的設備。
剖析:facility意為“設備”，常用其復數形式；latest是形容詞,意為“最新的”；equipment是不可數名詞,意為“設備”。
7.our chemistry teacher,mr longford,takes us to public science lectures about four times a term,and these are always very interesting,as the lecturers are people who have made real discoveries in their area of science.
我們的化學老師朗福德先生大約每個學期帶我們去聽四次大眾科學講座。這些總是很有趣,因為做講座的人都是在各自的科研領域里真正有所發現的人。
剖析:four times意為“四次”,表示次數時:一次用once;兩次用twice；三次以上用“基數詞+times”。 as the lecturers are people who have made real discoveries in their area of science.是原因狀語從句,意為“由于……”；make discoveries“有了發現”；in their area of...“在他們……的領域中”。
8.the fact is,canada has many first-class scientists.
事實是,加拿大有許多一流的科學家。
剖析:the fact is是插入語,從整個句式來看,這個句子也可改為:the fact is that canada has...;first-class是合成形容詞,意為“一流的”。
9.in the last twenty years,seven canadian scientists have won the nobel prize!
在過去的二十年里,七個加拿大科學家獲得了諾貝爾獎！
剖析:in the last twenty years,意為“在最近這二十年”,常與現在完成時連用。
10.i’m becoming more and more interested in physics,and have decided that i want to study it at university.
我對物理越來越感興趣,決心到大學學習。
剖析:要注意:become是瞬間動詞,用于進行時態時,表示“逐漸變得……”；more and more 意為“越來越……”。
