名词后面加形容词,1 形容词为后置定语 2 形容词为宾语补足语
1 There are three small boats available for hire.
主语是three small boats 谓语是are available for 宾语是hire 这个there be句型是个特殊结构,there并不是句子的主语,只是在句子中,构成这个结构
2 Let us suppose another planet with conditions similar to those on the earth这是个祈使句,句子的主语省略了,而以动词原形开头 ,let 谓语 ,let sb do sth是双宾结构 with conditions similar to those on the earth介词加名词,充当定语 similar to 如同those这些,指的是 conditions,on the earth在地球上,地点状语
3 The teacher主语 asked谓语 the students 宾语to be quiet宾语补足语
4 She 主语was angry with谓语 him宾语 for being late原因状语,for是介词,be late 是动词,所以,be加上ing,因为句子里不能有两个谓语,所以be不能以am/is/.are的形式出现,要以非谓语的形式出现!例如：I am afraid of being ill.我害怕生病!be ill是生病,但是句子的谓语是am,be是介词of后,加上ing.
