【答案】

 

 . millions

 .planets

 discovered/found

 .reading

 .already

 .me

 .been

 written

 .more

 .back

【解析】

試題分析:

 此題考查不確切數(shù)量的表達(dá)方式,在hundred,million等詞的復(fù)數(shù)后面加“s”表示不確切數(shù)量,故選millions.

 此題考查名詞的復(fù)數(shù)形式,planet是可數(shù)名詞,其他的行星就用other planets.

 此題考查動(dòng)詞的過去分詞,因發(fā)現(xiàn)在英文中用兩個(gè)單詞來表示,find和discover,它們的過去分詞形式是found和discovered。

 此題考查固定短語finish doing sth表示做完某事,故選reading。

 此題考查副詞,在肯定句中,表示已經(jīng)的副詞用already。

 此題考查人稱代詞,因前面有介詞for,故用賓格me。

 此題考查固定短語have been to 表示曾經(jīng)去過某地,故用been。

 此題考查固定結(jié)構(gòu)write to sb表示給某人寫信,因用完成時(shí),故用written。

 此題考查形容詞的比較級more。表示更多的。

 此題考查固定結(jié)構(gòu)write back表示回信的意思。

考點(diǎn):單詞的拼寫和單詞的適當(dāng)形式填空。

點(diǎn)評:此文重點(diǎn)介紹了一些天文知識。注意要把握好上下文的內(nèi)容的內(nèi)在聯(lián)系,根據(jù)漢語的提示的內(nèi)容,使文章內(nèi)容意思連貫一致。一定要把握好單詞的正確形式。
