【高考链接】(·江苏高考) ______ an imprtant decisin mre n emtin than n reasn, yu will regret it sner r later. A. Based B. Basing C. Base D. T base【解析】选B。考查非谓语动词。句意：如果把一个重要决定更多地建立在情感上而不是理智上, 你迟早会后悔的。根据题目与选项可知本题考查非谓语动词, C项是谓语动词, 首先排除。A项过去分词表示被动, 但句子的主语不是base的承受者, 因此A项应排除。B项和D项都表示主动, 但不定式表示将来, 在句中常作目的或结果状语, 与句意不符。
2. cmmand n. [C]命令；指令；[U]掌握 vt. 命令；指挥； 支配(1)at ne’s cmmand 听某人支配under ne’s cmmand＝under the cmmand f sb. 由某人指挥have a gd cmmand f 掌握；精通(尤指语言)(be)in cmmand f 掌握；控制take cmmand f 控制；担任……的指挥(2)cmmand sb. t d sth. 命令某人做某事cmmand that . . . (shuld) d . . . 命令……做……

【想一想】 cmmand后面跟从句时, 从句谓语用(shuld+) d/be dne, 想一想还有哪些动词有类似的用法？【参考答案】

【点津】可以说request sb. t d sth. 和require sb. t d sth. , 不可以说demand sb. t d sth. , 但可以说demand f sb. t d sth. 。
【高考链接】(·湖北高考)Duty is an act r a curse f actin that peple ______ yu t take by scial custms, law r religin. A. persuade B. expectC. request D. instruct【解析】选B。考查动词词义辨析。句意：职责是人们依据社会习俗、法律或者宗教信仰期望你践行的行动或行为过程。根据职责的定义可知, 它是人们的一种期待(expect)而不是请求(request), 因此选择B。persuade说服, 劝告； request要求, 请求； instruct命令, 指示, 这三项均与语境意义不符。
4. recgnize vt. 辨认出；承认；公认(1)recgnize sb. /ne’s vice 认出某人/听出某人的 声音recgnize . . . as/t be . . . 承认/公认……是……recgnize that . . . 认识到/承认……It is (generally) recgnized that. . . 人们公认……(2)recgnitin n. 认出；认识ut f/beynd recgnitin 认不出来

【高考链接】(·辽宁高考)Alexander tried t get his wrk _____ in the medical circles. A. t recgnize B. recgnizingC. recgnize D. recgnized【解析】选D。句意：亚历山大试图让他的工作在医学圈内得到认可。宾语his wrk和recgnize之间存在被动关系, 所以用过去分词作宾语补足语。
5. cme up观察句子, 写出黑体部分的含义①An ld lady came up t me and asked fr directins. ( )②A gd slutin t the prblem came up at the meeting. ( )
③When the mn came up, the yung peple began their celebratin. ( )④Plants cme up again every spring. ( )⑤I’ll let him knw if anything cmes up. ( )
【点津】(1)cme up“被提出”, 其主语是被提出的内容, 主动表示被动； (2)cme up with“提出”, 其主语是提出某项内容的人, 后面的宾语是被提出的内容。例如：They came up with the plan at the meeting yesterday. 他们在昨天的会议上提出了这个计划。
【助记】 cme up 面面观
【高考链接】(·浙江高考)—Alvin, are yu cming with us? —I’d lve t, but smething unexpected ______. A. has cme up B. was cming upC. had cme up D. wuld cme up
【解析】选A。考查时态。句意：——阿尔文, 你和我们一块来吗？——我愿意, 但是发生了意想不到的事。has cme up为现在完成时, 表示过去的动作对现在造成影响；was cming up表示过去某一时间正在进行的动作；had cme up为过去完成时, 表示过去某一时间之前已完成的动作；wuld cme up表示从过去某一时间看将要发生的动作。根据语境“我愿意, 但是发生了意想不到的事”导致了我没去, 强调对现在的影响。故选A。
6. make use f利用；使用
①(·湖北高考)My experience tells me that it is nt what yu are given but hw yu _____ ___ __ it that determines wh yu are. 我的经历告诉我不是你拥有什么而是你怎样利用你所拥有的决定了你的未来。②Scientists are develping new ways t _____ ___ _________ __ the slar energy mre effectively. 科学家们正在开发更加有效地充分利用太阳能的新途径。【点津】 make use f短语的构成特点为：动词+名词+介词。此类短语使用时通常做以下变化：(1)把use提前使用被动语态；(2)把use提前作先行词用, 其后接定语从句。
③We shuld think f what use can be made f such material. 我们应该考虑怎么用这种材料。④His success lies in the use that he can make f every chance t imprve himself. 他的成功在于他善于利用每一个机会来提升自己。
7. Native English speakers can understand each ther even if they dn’t speak the same kind f English. 以英语作为母语的人, 即使他们所讲的语言不尽相同, 也可以互相理解。even if引导让步状语从句, 相当于even thugh, 意为“即使, 尽管”。① Even if yu take a taxi, yu will still miss the train. 即使你乘出租车也赶不上这班火车了。②Even thugh we culd affrd it, we wuldn’t g abrad fr ur vacatin. 即使我们付得起这笔钱, 我们也不出国度假。
【高考链接】(·北京高考)—Lk at thse cluds! —Dn’t wrry. ______ it rains, we’ll still have a great time. A. Even if B. As thughC. In case D. If nly【解析】选A。考查连词。句意：——看看那些乌云！——别担心。即使下雨, 我们仍然会玩得很开心。even if虽然, 即使；as thugh好像, 仿佛；in case万一, 以防；if nly要是……就好了。
8. It was based mre n German than the English we speak at present. 当时的英语更多地是以德语为基础, 而不是我们今天所说的英语。
(1)mre . . . than . . . 与其说……倒不如说……mre than＋数词或从句 超过mre than＋形容词 非常mre than＋名词 不只是；不仅是(2)n mre than 只不过；仅仅nt mre than 不超过；至多rather than 而不是ther than 除了；不同于

9. Believe it r nt, there is n such thing as standard English. 信不信由你, (世界上)没有什么标准英语。“n such＋单数名词”意为“没有这样的……”, 其中单数名词前不可再加冠词, 相当于“nt such a/an＋单数名词”。 ①In the men’s 110m hurdles final, America’s Merritt wn the gld medal, but Liu Xiang had n such luck. 在110米跨栏决赛中来自美国的梅里特夺得金牌, 刘翔却没有这样的运气。②We can find n such tur guide in ur city. 在我们这座城市我们找不到这样的导游。
