As a matter of fact,           beauty of           nature there made an excellent impression on me.

a; the; /

a; the; the

the; the; /

a; /; the

考察冠词。句意：事实上，那里的自然之美给我留下了极好的印象。as a matter of fact “ 事实上”，为固定短语。第二个空表示特指，用定冠词the。Nature表示“大自然，自然界”时，前面一般不加冠词。故选A项。

The law           equal rights for men and women.

permits

confirms

persevers

guarantees

考查动词辨析。句意：这个法律确保了男女权利平等。A.permit允许；B.confirm证实，证明；C.persever坚持；D.guarantee保证，担保。分析句意可知，空格处为动词做谓语，其主语为the law,为单数则谓语动词用第三人称单数形式。又因the law作用是保证公平。故选D项。

— Father, you promised!

—Well,____．But it was you who didn't keep your word first．

so was I 

so did I 

so I was 

so I did

考查部分倒装“So + be/情态动词/助动词 + 主语”与表强调的“So + 主语 + be/情态动词/助动词”区别。根据语境“you promised（你许诺过）”和答语“But it was …”可知爸爸回答“我的确许诺过”，且promised是过去时，所以表强调要用助动词did,故选D。句意：——爸爸，你许诺过。——好啦，我的确许诺过。但是是你先没有遵守诺言。

           is reported in the newspaper, the epidemic situation is getting better now in China.

It

As

That

What

考查定语从句。句意：正如报纸上报道的那样，中国的疫情正在好转。分析句子结构可知，空格处引导一个非限制定语从句，先行词是整个主句内容，关系词在从句中做主语，表示“正如”，应用as引导，as 引导非限制性定语从句 ，位置比较灵活，可放在主句前。故选B项。

______about wild plants that they decided to make a trip to Madagascar for further research.

So curious the couple was

So curious were the couple

How curious the couple were

The couple was such curious

used to

used to be

used to do

was used to

考查词组和省略式，used to do“过去常常’,be used to do “被用来做”，句意是：--你现在是志愿者吗？--不但我过去是，去年我为市运动会工作。可以排除D项，因为这是省略句，完整的是I used to be a volunteer。英语中如果不定式的部分是重复上文可以省略to后面的内容，但是如果to后面是be动词或助动词have，就不省略。选B。

When           another country, you should be aware of those differences and respect them.

visit

to visit

visiting

visited

考查非谓语动词。句意：当拜访另一个国家时，你应该知道这些不同之处并尊重它们。分析句子可知，空格处应填非谓语动词和when一起构成时间状语，逻辑主语you和visit之间是主动关系，应用现在分词。故选C项。
