六、形容词、副词： 形容词：用来说明或修饰名词、代词的词称为形容词。 1.形容词的句法作用：作句子中名词的定语、句子的表语以及宾语补足语。 2.形容词在句子中的位置： ⑴作定语时放在名词的前面,且音节少的词放在音节多的词之前。如：a big yellow wooden wheel ⑵作表语时放在连系动词之后。如：The price sounds reasonable. ⑶作宾语补足语时放在宾语之后。如：We must try our best to keep our environment clean. ⑷后置的情况： ①修饰复合不定代词时放在代词之后。如：Something serious has happened to him. ②与表示长、宽、高、重、老、远离的词连用时形容词后置。如：Hes 1.8 metres tall.The moon is about 380,000 kilometres away from the earth. 3.有关形容词的用法辨析： ⑴ whole与all：记住两个词序：① the whole + 名词; ②all the + 名词。如：He was busy the whole morning. / He can remember all the words he learns. ⑵ tall与high, short与low：指人的个子时用tall与short;指其他事物时一般用high与low。如：Hes very tall/short. / Tall trees are standing on both sides of that avenue. / A few people live on high mountains. |
