step2 language points
1. demand
demand可用作名词和动词。
demand sth. 要求得到某物
demand to do sth. 要求去做某事
demand that sb. (should) do sth. 要求某人做某事
meet/satisfy one's demands 满足某人的需求
a demand for sth. 对……的需求
supply and demand 供求
①he demanded ________(tell) everything.
②they demanded she ________(go) there together.
③this is a demanding job which ________(demand) patience.
2. opportunity，chance
这两个名词都有“机会”的意思。
①opportunity一般指有利的机会，chance指的机会可能有利，也可能不利，两者后接不定式或of＋doing。如：
he has a chance/opportunity to see the premier.
＝he has a chance/opportunity of seeing the premier.
②chance有“可能性”的意思，opportunity则没有。
有可能做 there is a chance/possibility of sb. doing
＝there is a chance/possibility ＋that从句
＝(the) chances are that...
③take this opportunity意为“趁此机会”；
take a chance＝take chances意为“冒险；投机”。
④chance可用作动词，opportunity则不能。如：
i chanced to see our old headmaster in the street some days ago.
3. decline，refuse，reject，deny
decline意为“婉谢”(客气礼貌)；还可意为“下降；衰落”；refuse意为“拒绝”(中性词)；reject意为“断然拒绝”(强烈坚决)；deny意为“否认；拒绝给予”。
从用法上看：
decline和refuse后接不定式to do，reject后一般不接不定式。deny意为“否认”时，后接动名词；表“拒绝给予某人”的搭配为deny sb. sth.或deny sth. to sb.。
on the decline＝in decline＝decline 在衰退
decline sth.＝turn sth. down 婉拒
on the decline＝on the decrease 在减少中
a decline/decrease in population 人口的减少
①he ________ to answer my question.
②he was busy and ________ the invitation to his friend's party.
③some parents ________ nothing to their children.
