本文是一篇說明文。文章介紹了地球上生命起源,主要簡(jiǎn)述了由植物到動(dòng)物,由低級(jí)生命到哺乳動(dòng)物進(jìn)化的過程。

1

考查副詞。句意:數(shù)百萬(wàn)年以后,極其微小的植物開始出現(xiàn)在水的表面。此處為副詞修飾形容詞small。extremely“極其。故填extremely。

2

考查動(dòng)詞搭配。句意:他們快速繁殖,并使海洋充滿了氧氣,氧氣促進(jìn)了后來貝殼類生物和魚類的發(fā)展。本題考查固定搭配:fill……with……使......充滿……。故填with。

3

考查非限制定語(yǔ)從句。句意:他們快速繁殖,并使海洋充滿了氧氣,氧氣促進(jìn)了后來貝殼類生物和魚類的發(fā)展。根據(jù)句意可知此處為非限制性定語(yǔ)從句修飾先行詞oxygen, 且從句中缺主語(yǔ),故填which。

4

考查一般過去式的被動(dòng)語(yǔ)態(tài)。句意:他們之后是陸地動(dòng)物。此處they代指green plants,而綠色植物應(yīng)該是被陸地動(dòng)物跟隨,因此應(yīng)該用被動(dòng)語(yǔ)態(tài),且此處講述過去的事情,因此應(yīng)用一般過去時(shí)的被動(dòng)語(yǔ)態(tài)。故填were followed

5

考查代詞。句意:一些動(dòng)物是昆蟲,其他的被稱為兩棲動(dòng)物,可以在陸地和水中生活。從處應(yīng)該是指上句中land animals中的一些(除了昆蟲之外)的一些動(dòng)物,others其他的,別的,等同于other land animals。故填Others。

6

考查介詞。句意:其他的被稱為兩棲動(dòng)物,可以在陸地和水中生活。此處為省略句,其完整形式為:Others were able to live on land as well as(live) in the water.,在水中用介詞in。故填in。

7

考查一般過去時(shí)。句意:它們也產(chǎn)卵,并且在地球上存在超過一億四千萬(wàn)年。本文主要是敘述了過去地球上生物的進(jìn)化,因此此處應(yīng)該用一般過去時(shí),動(dòng)詞lay意為放置,產(chǎn)卵,下蛋,他它的過去式和過去分詞為laid。故填laid。

8

考查副詞。句意:然而,六千五百萬(wàn)年前,恐龍時(shí)代終結(jié)了。前句:它們也產(chǎn)卵,并且在地球上存在超過一億四千萬(wàn)年提到了恐龍這一物種的發(fā)展,與恐龍時(shí)代的終結(jié)構(gòu)成鮮明的轉(zhuǎn)折,因此應(yīng)用轉(zhuǎn)折副詞however,意為然而。故填However。

9

考查名詞。句意:(恐龍的)消失使地球上哺乳動(dòng)物的興起成為可能。根據(jù)空前的定冠詞the可知此處應(yīng)填名詞,結(jié)合句意可得出此處意為恐龍的消失,disappear的名詞為disappearance。故填disappearance。

10

考查連詞。句意:這些動(dòng)物不同于以前的所有生命形式,因?yàn)樗鼈兩?dòng)物并產(chǎn)奶喂養(yǎng)它們。根據(jù)句意可知此處為因果關(guān)系,因此,應(yīng)用because引導(dǎo)原因狀語(yǔ)從句。故填because。
