toExposure語法：Adverialclausewithwh-ever&nomatterwh-一.Nomatter+特殊疑問詞(what,which,who,whom,whose,when,where,how)引導讓步狀語從句；二.特殊疑問詞（what,which,who,whom,whose,when,where,how）+ever既可以引導讓步狀語從句，又可以引導名詞性從句。三.易錯提示：1.Nomatterwhat(或Whatever)+名詞+從句，+主句；2.Nomatterhow(或However)+形容詞或副詞+從句，+主句;3.Nomatterwhether+從句，意為“無論是否......”。

單元重點句型1

1.Onlythencanwelooktowardsharmoniouslysharingoururbanhabitats.只有這樣，我們才能和諧地共享我們的城市棲息地?！揪湫头治觥?/p>

“only+狀語或者狀語從句”位于句首時，該單句或者主句的主謂采用部分倒裝。注意：only修飾句子的主語時，該句不倒裝。【句型拓展】1.否定詞+狀語位于句首，其后習慣上采用部分倒裝；2.not…until句型，當notuntil…位于句首時，其后的主句要用倒裝語序；3.notonly…butalso句型中，notonly句首引出的分句通常用部分倒裝形式。

【句型分析】

在比較句型中，“否定詞+比較級”即形容詞的比較級用在否定結構中，可以表示“最……不過”、“不比……更”的意思，相當于形容詞的最高級的含義?！揪湫屯卣埂勘容^級形式表示最高級含有的其它結構：

比較級+than+anyother+單數(shù)名詞；anyoftheother+復數(shù)名詞；alltheother+復數(shù)名詞；anyone/anythingelse.
