When Huawei P20 came out,         people couldn't wait to buy one in our town.

thousand

thousands

thousand of

thousands of

考查數(shù)詞的用法。句意：當(dāng)華為P20上市時(shí)，成千上萬的人迫不及待的想在我們鎮(zhèn)上買一臺。thousnad意思是“千”，其前有具體數(shù)詞修飾時(shí)，用其單數(shù)形式；當(dāng)其前沒有具體數(shù)詞修飾時(shí)，用其復(fù)數(shù)形式，且與of 連用，thousands of“成千上萬的”，這里沒有具體數(shù)詞修飾。故選D項(xiàng)。

---Shall we have a talk with her tonight?

---There is no        talking to her. She will never listen.

good

value

point

worth

考查名詞詞義辨析。句意：---我們今晚要和她談?wù)剢幔?---和她談話沒有意義，她不會聽。A.good 好處  ； B.value 價(jià)值；C.point要點(diǎn)；D.worth價(jià)值。根據(jù)句意可知可知，此處是固定表達(dá)There  is no point (in) doing sth 做某事沒有意義。故選C項(xiàng)。

---It's burning hot today,isn't it?

---Yes,_____yesterday.

So was it

So it was

So it is

So is it

句意：“今天太熱了，是不是？”“是呀，昨天也一樣”。如果表示前面所說的肯定情況也適合于另一者，要用“so+助動(dòng)詞/情態(tài)動(dòng)詞/系動(dòng)詞+主語”。

used to

used to be

used to do

was used to

考查詞組和省略式，used to do“過去常?！?be used to do “被用來做”，句意是：--你現(xiàn)在是志愿者嗎？--不但我過去是，去年我為市運(yùn)動(dòng)會工作。可以排除D項(xiàng)，因?yàn)檫@是省略句，完整的是I used to be a volunteer。英語中如果不定式的部分是重復(fù)上文可以省略to后面的內(nèi)容，但是如果to后面是be動(dòng)詞或助動(dòng)詞have，就不省略。選B。

The most important promises we must keep are          we make to ourselves.

ones

those

these

them

考查代詞。句意：我們必須遵守的最重要的承諾就是我們對自己做出的承諾。A. ones泛指上文提到的可數(shù)名詞復(fù)數(shù)；B. those特指上文提到的可數(shù)名詞復(fù)數(shù)；C. these這些；D.them他們。分析句子可知，為we must 是定語從句，修飾The most important promises，是句子的主語；be動(dòng)詞后缺少表演，we make to ourselves是定語從句，修飾空格處。根據(jù)句意，此處指上文提到的promises,由定語從句修飾表示特指，故用 those。故選B項(xiàng)。

Going on a trip into         space must be quite         exciting experience.

/; the 

/; an

the; the 

the; an

考查冠詞。句意：太空旅行是令人興奮的經(jīng)歷。第一空不填，space前面不加冠詞，第二空后面的experience作“經(jīng)歷”時(shí)是可數(shù)名詞，表示“一次令人興奮的經(jīng)歷"。exciting首字母的發(fā)音為元音音素，因此應(yīng)填an。故選B項(xiàng)。
