句意：莉莉经常在晚饭之前弹吉他。但是昨天她晚饭后弹吉他。
考查时态。play“玩，弹奏”，第一空根据“usually”可知，此处用一般现在时，主语Lily是第三人称单数形式，谓语动词用第三人称单数形式，排除AB两项。第二空根据“yesterday”可知，此处用一般过去时，play的过去式是played，故选C。

A．unbelievableB．perfectC．prgressD．perfrmance
【标准答案】B

考查形容词的用法和辨析。unbelievable难以置信的，形容词；perfect完美的，形容词；prgress进步，名词；perfrmance表演，名词。根据成分分析可知，此空应填形容词作表语，故排除C和D；根据“I like the TV shw...”可知，“我”喜欢这部电视剧，那么“我”对这部电视剧的评价应是好的，由此可知“我”会认为它的结局是完美的。故选B。

句意：——你错过了一场激动人心的足球比赛。——这没什么大不了的。我不喜欢足球。
考查不定冠词的用法。一场足球比赛，可数名词，且第一次提到。用a/an表示泛指，exciting[ɪk’ saɪtɪŋ]，元音音素开头，所以用an；nt a big deal，不是什么大事，是个固定搭配。故选C。

C．S Lucy didD．Neither Lucy did

【点睛】
explain的用法
explain在英语中只有动词的用法，分为及物动词和不及物动词，意思为讲解，解释，说明等。
explain在动词中的用法后面一般跟explain sth t sb或 后接反身代词作宾语，具体如下：
1. 表示“解释”，通常不接双宾语；若语义上需要这类结构，可以改用 explain sth t sb结构。如：请把这条规则给我们解释一下。Please explain this rule t us.
若其中的 sth 较长或较复杂（比如是不定式或从句），也可以用explain t sb sth。如：
He explained t us why he was late. 他给我们解释了他迟到的原因。
2. 有时后接反身代词作宾语，有两个意思。如：
(1) 表示把自己的意思表达清楚。如：
Culd yu explain yurself a bit mre? 你能把意思说得更清楚点吗?
(2) 表示对自己的行为进行解释。如；
Late again, Smith? I hpe yu can explain yurself! 又迟到了，史密斯?我希望你能说明一下原因！
四、句型转换(共8分)
Cmplete the fllwing sentences as required（根据所给要求，完成下列句子）：
30．Turn ff the mbile phne. （改为否定句）
________ ________ ff the mbile phne.
31．Qu Yuan gave sme helpful advice t the king at that time. （改为感叹句）
________ ________ advice Qu Yuan gave t the king at that time!
32．The sunrise was very beautiful. I culdn’t take my eyes ff it. （合并成一句）
The sunrise was ________ beautiful ________ I culdn’t take my eyes ff it.
33．the first, an abacus, ne f, calculating, was, machines（连词成句）
________________________________________________________.
【标准答案】
30． Dn’t turn
31． What helpful
32． s that
33．One f the first calculating machines was an abacus. /An abacus was ne f the first calculating machines.
30．根据句子结构，原句是一个肯定祈使句。改为否定祈使句的结构为：dn’t+动词原形+其他。位于句首的单词首字母要大写，所以空格处填Dn’t turn。故答案为Dn’t turn。
31．感叹句的结构为：hw+形容词+主语+谓语；what+形容词+不可数名词+主语+谓语。原句中helpful表示“有帮助的”，形容词；advice表示“建议”，不可数名词，所以变感叹句用what+形容词+不可数名词+主语+谓语的结构，位于句首的单词首字母要大写，所以空格处填What helpful。故答案为What helpful。
32．将两个句子合并为一句，用连词连接两个句子。根据句意，The sunrise was very beautiful“日出非常美丽”，I culdn’t take my eyes ff it“我无法将目光从它身上移开”，后文是表示结果，所以用引导结果状语连词s…that/such…that。s+形容词+that从句；such+a/an+形容词+名词+that从句。beautiful是形容词，所以用连词s…that。故答案为s that。
33．the first序数词，表示“第一”；an abacus可数名词单数，表示“一个算盘”；ne f，表示“……之一”；calculating计算的，形容词；was系动词的一般过去时；machines机器，名词复数，所以句子为One f the first calculating machines was an abacus. /An abacus was ne f the first calculating machines。故答案为One f the first calculating machines was an abacus. /An abacus was ne f the first calculating machines。
