考查省略句。當(dāng)狀語(yǔ)從句的主語(yǔ)和主句主語(yǔ)一致，且狀語(yǔ)從句中有be動(dòng)詞的時(shí)候，可以把狀語(yǔ)從句的主語(yǔ)和be動(dòng)詞一起省略，本題if后面省略了I am，句意：每天晚上吃完晚飯以后，如果不是很累，我就會(huì)花點(diǎn)時(shí)間來(lái)遛狗。故C正確。

"Society" is a(n)              term;it may mean much or nothing.

autonomous

ambiguous

fragrant

fragile

考查形容詞詞義辨析。句意：“社會(huì)”是一個(gè)模棱兩可的詞；它可能意味著很多，也可能沒(méi)有意義。autonmous 自治的；ambiguous模棱兩可的；fragrant芳香的；fragile脆弱的。結(jié)合后文it may mean much or nothing可知，空格處填ambiguous模棱兩可的。故選B項(xiàng)。

I found _____ convenient to shop online at home .

it’s 

that

it

that was

考查強(qiáng)調(diào)句。句意：我發(fā)現(xiàn)在家網(wǎng)購(gòu)很方便。這里it指代后面的to shop online。其中的強(qiáng)調(diào)句式是：主語(yǔ)+find it +形容詞+to do，意為主語(yǔ)發(fā)現(xiàn)做某事是...的，故選C。

When            to someone,I usually say, "Pleased to meet you."

introduce

introduced

introducing

am introduced

考查過(guò)去分詞和省略。句意：當(dāng)我被介紹給別人時(shí)，我通常會(huì)說(shuō)：“很高興認(rèn)識(shí)你”。根據(jù)句子結(jié)構(gòu)可知，本句是when引導(dǎo)的時(shí)間狀語(yǔ)從句，原句when I am introduced to someone,這里當(dāng)從句主語(yǔ)與主句主語(yǔ)一致時(shí)，并且從句的謂語(yǔ)動(dòng)詞有be這時(shí)從句的主語(yǔ)與be同時(shí)省略，所以空格處introduced。故選B項(xiàng)。

考查數(shù)詞。句意：一年有24個(gè)節(jié)氣。谷雨通常在一年中的四月開(kāi)始?？崭袂坝卸ü谠~the,與可數(shù)名詞單數(shù)month，要用序數(shù)詞。根據(jù)

Grain Rain often starts in Apirl，可知四月份是一年之中的第四個(gè)月，要用序數(shù)詞fourth。故選B項(xiàng)。
