Complete the passage with proper words according to Passage A and B.
It is hard to think of a world without metals. Different metals have different uses, for example, iron can be used in ________ equipment. But above all we should know whether it will ____ under
electrical
react
different conditions. Otherwise it will keep the equipment from working well. As we all know, if iron is heated in oxygen, it will react slowly but will not form an _____.
oxide
On the other hand, if it is put together with water or _____, there will be a ______ reaction. Next let’s do an __________ to support the above. First, get a test tube filled with water and put it over the _____________ to ____ for three minutes.
steam
partial
experiment
Bunsen burner
boil
Then put three or four clean nails in the water with some oil added to it and leave the tube for one week. What happens The iron does not ____ in air-free water. Another experiment, if you put the nails in the tube with the air in it for one week, then what happens Iron rusts in _______ water.
rust
ordinary
Which of the following reacts most
easily with steam
A. Potassium. B. Iron.
C. Magnesium. D. Calcium.
Read Passage A (P44) and Passage B (P45) again and choose the best answers.
2. Which of the following reacts least with
water
A. Copper. B. Iron.
C. Aluminium. D. Sodium.
3. What can we learn mainly from Passage
B？
A. How iron reacts with air.
B. How iron is made.
C. How we can prevent iron from rusting.
D. How iron reacts with steam.
1. When we use metals, it is important to know how they react with different substances, for example, water and oxygen.
= When we use metals, we should know how metals react with different substances, for example, water and oxygen, which is very important.
本句是一个复合句，其中when引导时间状语从句；在主句中，it为形式主语，真正的主语是动词不定式短语to know ... substances，其中how ... substances为how引导的宾语从句，作know的宾语， for example引出同位语，表示举例。
2. Here is a table with the metals that react most at the top, and the metals that react least at the bottom.
= A table is here. At the top of the table we can see the metals that react most and at the bottom of the table we can see metals that react least.
本句使用了倒装语序。句子的主语是a table，后面的with ... bottom作定语修饰a table；两个that都引导定语从句修饰the metals。
