A. launched B. to launch C. being launched D. launching（发射） 【考点】考察非谓语动词用法【答案】A【解析】本句实际上考察的是分词做定语。当分词做定语的时候，如果构成分词的动词与名词构成主动关系，就使用现在分词做定语；当二者构成被动关系，使用过去分词做定语。单独的一个分词做定语要放在名词的前面，分词短语做定语要放在分词的后面。本句的中的名词Chinas first moon rover与动词launch构成逻辑上的被动关系，故使用过去分词短语在句中做定语。句意：在12月早些时候发射的中国第一个月球登陆者，被命名为玉兔或者“Jade rabbit” 。故A正确。【举一反三】The Town Hall _ in the 1800s was the most distinguished building at that time.

The living room is clean and tidy , with a dining table already _ for a meal to be cooked . A. laid B. laying C. to lay D. being laid 【考点】考察with符合结构【答案】A【解析】with的复合结构相当于一个状语从句，其基本结构为：with+宾语+宾语补足语；宾语补足语可以是名词，代词，形容词，副词，现在分词，或者过去分词，也可以是不定式。对宾语的情况进行补充说明。当做宾语补足语的动词与宾语构成被动关系的时候，使用过去分词的形式；当二者构成主动关系的时候，使用现在分词的形式。要特别要注意With的复合结构经常与独立主格结构转换使用。本句中的动词lay“铺，放置，搁”与名词a dining table构成逻辑上的被动关系，故使用过去分词在句中做宾语补足语。句意：起居室很干净整洁，有一张桌子已经被铺好为即将做好的饭菜做好准备。故A正确。30.

The policeman stopped him when he was driving home and _ him of speeding . A. charged B. accused C. blamed D. criticized 【考点】考察动词固定搭配【答案】B【解析】固定搭配charge sb with sth控告某人犯.罪；accuse sb of.控告某人.罪；blame sb for sth因为某事责备某人；criticize sb for sth因为某事批评某人；监狱：当地开车回家的时候，警察阻止了他，控告他超速。根据本句横线后面的of说明本句应该使用动词accuse，因为accuse可以和介词of连用。故B正确。【举一反三】（山东省临沭县xx届高三普通高等学校招生考试打靶试题）In the interview, he had finally _ several customers of the advantages of his productA. convinced B. reminded C. accused D. informed答案：A考查动词词义辨析。解题关键：掌握短语convince 。of。33. The old couple have been married for 40 years and never once _with each other. A. they had quarreled B. theyve quarreled C. have they quarreled D. had they quarreled 【考点】考察倒装句【答案】C【解析】部分倒装中考查较多的有：(1) 含有否定意义的词never，seldom，little. hardly，not，scarcely，nowhere，by no means(决不)等置于句首时。(2)以only修饰作为状语的副词、介词短语或从句，且放在句首时。注意：only 修饰状语从句放在句首时，状语从句不需要倒装，只能倒装主句部分。(3)当so置于句首意为“也如此”，neither，nor置于句首意为“也不”时。当so表示对前句内容的肯定和附和，译作“确实，正是”时，用自然语序。(4)当not onlybut also, sosuchthat, not until, no sooner than, hardly when等连词置于句首时。(5)在as引导的让步状语从句中(名词形容词/副词动词+as+主谓结构)。(6)虚拟语气的条件状语从句省去 if时，须将were，had，should提到句首构成倒装句。(7)频度副词often, always, once, now and then, every other day, many a time等放在句首时。(8)为了使句子保持平衡，为了强调表语或为了使上下文紧密衔接时，常使用倒装语序。本句中and连接的第二个分句是以否定词never引起的，所以后面的主句使用部分倒装的形式。句意：这对老夫妻结婚了40年，一次也没有吵过架。根据句意说明他们结婚40年来一次也没有吵架。根据句意说明使用现在完成时的被动语态。故C正确。【举一反三】Its nice.

A. voices had e B. came voices C. voices would e D. did voices e答案B考点解析副词then位于句首, 且当句子的主语是名词时, 句子用全部倒装句, 选B。35. My father bought me an _ guitar as my birthday present .

At the Holiday Shop students can buy things like necklaces, key chains, and other small items for their friends and family as Christmas gifts. Since my brother really wanted to take part, my mom gave him two dollars to buy his Christmas gifts. My mom didnt know that he had picked out a special necklace for her. When he got home from the Holiday Shop that day, he couldnt wait to show it to me. He pulled out a little green box and opened it. Inside was a gold chain with a little red flower and a man-made diamond next to gold letters that spelled out,“Grandmother”. “Wow,” I said.“Its beautiful.” Since my brother was in the first grade and was just learning to read, he didnt realize that the necklace said “Grandmother” instead of “Mother”. I knew that on Christmas morning, when he found out he had bought the wrong necklace, he would be very unhappy, so I said nothing more about it. My brother ran and put the necklace under his bed to hide it from Mom until Christmas morning. When he wasnt looking, I took the necklace and put it in my backpack. The next day I took it back to school and asked the woman who ran the Holiday Shop if I could change it for the “Mother” necklace. She said yes. When I got home that day, I put the necklace under my brothers bed.When my mom opened it up on Christmas morning, my brother was so exalted! My moms eyes were filled with joy.
