考查冠词。the定冠词；an不定冠词，用在以元音音素开头的单词前，表泛指；a不定冠词，用在以辅音音素开头的单词前，表泛指，固定搭配in the future“在未来”，排除B和D，“volleyball player”是可数名词单数，所以用不定冠词表泛指，“excellent”是以元音音素开头的单词，所以第二个空用不定冠词an，排除C，故选A。
2．I was talking with my friend in the living room ________ my mum came in.
A．because B．when C．since D．while
【答案】B

句意：当我妈妈进来的时候，我正在客厅和朋友聊天。
考查连词辨析。because因为；when当……时候； since自从；while当……时候。while引导的时间状语从句，从句谓语用延续性动词，“came”为非延续性动词，故排除D；根据“I was talking with my friend in the living room”可知，此处是when引导的时间状语从句，主句是过去进行时，从句用一般过去时态。故选B。

A．dozen B．half a dozen C．dozen of D．two dozens

考查形容词的最高级。exciting为原级；more exciting为比较级；less exciting为比较级；the most exciting为最高级。“one of+the+形容词最高级+可数名词的复数形式”表示“最……之一”，为固定搭配。故选D。

【答案】11．flew
12． whether were
13． ought not
14． not right to
15．Benjamin Franklin began his experiments on electricity over two centuries ago.
11．此处用一般过去时，把谓语动词flies改为过去式，故此处为flew。
12．把一般疑问句Are articles with pictures more attractive than those with only words 变为宾语从句，用引导词whether，主句谓语asked是一般过去时，宾语从句的谓语用一般过去时，因此把are变为were。故此处为whether, were。
13．ought to的否定形式为out not to。故此处为ought not。
14．Don’t play in the fountains or sleep on the benches.“不要在喷泉里玩或者在长椅上睡觉”，因此在喷泉里玩和在长椅上睡觉是不对的，用句型It is not right to do sth“做某事是不对的”，故此处为not, right, to。
15．over two centuries ago“两个多世纪以前”，作时间状语，位于句末。谓语began后面接名词短语his experiments on electricity作宾语，began his experiments on electricity表示开始做有关电的实验，故此处为Benjamin Franklin began his experiments on electricity over two centuries ago.
