试题分析:句意:如今互联网变得越来越受欢迎和一条新高速宽带网络最近开始运营。第一空特指双方都知道的事;第二空则是泛指,由句意可知选B。
考点:考查冠词的用法。【解析】【答案】B2、B【分析】句意;在玛丽照顾我母亲的几个月里,我和她一直通信。correspondwith和通信,符合句意;write与to搭配,给写信;communicate通常与with连用;competewith与竞争。故选B。【解析】B3、C【分析】答案:C该句含有表语从句,在表语从句中,如果不缺主语,不缺宾语,不缺定语,不缺表语,那么就是缺状语,如果缺少地点状语,则填where,句中lie本来和in搭配,现在没有in,就用连接副词where.
这就是问题所在.
表语从句(PredicativeClause)就是用一个句子作为表语,其引导词根据后面从句的意思以及成分来决定.【解析】C4、D【分析】考查定语从句,这里是一个非限制性定语从句,先行词是somanypeople,指人时,关系代词用whom或who,介词后则只能用whom,故选D。【解析】D5、A【分析】答案是A.本题考查同位语从句中的引导词;Thereisno/littledoubtthat毫无疑问;题干中空格后面是说明doubt内容的同位语从句;从句从意思到成分都是完整的;所以选择在名词性从句中不担任成分;无意义that;
故选:A.
毫无疑问;如果你对自己有信心,你就能判断真理和错误.
名词性从句考查的关键是连接词的选用和语序,因此,我们首先要搞清从句的性质,掌握各连接词的用法,在此基础上判断.此外,关注名词性从句用陈述语序.【解析】A6、C【分析】本题考查名词词义辨析.A.balcony阳台;B.blank填空处,空白处;C.bench长凳;D.byproduct副产品.根据句意可知答案.
故选:C.
后来;我的身体开始变得越来越虚弱,以至于只能坐在体育场的长凳上欣赏足球了.
本题考查名词词义辨析,考生在平时的学习中应注意积累相应的词汇和搭配,并牢记其意思.在做题时,将词义和题干相结合,从语法、句子结构尤其是句意上去判断,句意通顺,符合逻辑,即正确答案.【解析】C7、C【分析】题干中never为否定词,置于句首时句子要部分倒装,其结构为"never+be/助动词/情态动词+主语+谓语剩余部分";所以排除选项B和D.再者根据定语从句中的一般现在时态,可排除选项A,因为A选项表示"过去的过去",所以此题选C
她之前从未见过谁打网球打得和Robert一样的好.
此题考查否定词或短语置于句首,句子部分倒装.当具有否定的词或短语置于句首时,句子部分倒装,其结构为"否定词或短语+be/助动词/情态动词+主语+谓语剩余部分".常见否定词或短语有:seldom,hardly,rarely,little,few,not,no,never,atnotime,innoway,innocase,innosense,onnoaccount,onnoconsideration,bynomeans,notonlybutalso(前倒后不倒),notuntil(主倒从不倒),nosoonerthan(主倒从不倒,且主句用过去完成时式),hardlywhen(主倒从不倒,且主句用过去完成式)【解析】C8、B【分析】答案是B.考查谓语动词的单复数形式.根据英语语法,"分数或百分数+ofthe+名词或代词"作主语时,谓语动词的单、复数形式取决于名词或代词的单、复数形式.Onethirdof后面的名词area是不可数名词,所以谓语用be动词的单数形式is;seventypercentof后面的名词trees是复数形式,所以谓语用复数形式,句中时间状语recently表面句子是现在完成时态;所以用助动词have.故选B.
1/3的地区覆盖着树.约70%的树是最近种植的.
解答此类题目首先要掌握时态的用法及谓语动词的单复数规则,然后根据语境选择正确的答案.【解析】B9、D【分析】答案:D.shaky;颤抖的;heavy,沉重的;casual,漠不关心的,冷淡的;steady平稳的.由though可知,句子前后意思转折.slow与steady形成对比.故选D项.
句意:这位老工程师的双眼仍然神采奕奕;即便满脸已经布满了皱纹.在穿过这个房间的时候,尽管走得很慢,但是却很平稳.
考察形容词词义辨析.只要弄清每个形容词的意思,再根据句意做出判断即可.【解析】D二、填空题(共9题,共18分)10、D【分析】【解析】试题分析:整个句子已经有谓语动词,故空格处该用非谓语动词,这里Compare与she之间是被动关系,故用过去分词。考点:考查非谓语动词的用法。【解析】【答案】D11、D【分析】【解析】试题分析:考查宾语补足语。第一空himself与sit构成主动关系,使用现在分词的形式。第二空的hands与tie(捆,系)构成被动关系,故使用过去分词。句意:当他苏醒过来的时候,分析自己做在椅子上,手被捆在后面。故D正确。考点:考查宾语补足语【解析】【答案】D12、A【分析】考查非谓语动词。一个重达两吨的嫦娥二号卫星,weigh做动词表示重达,不可用于被动。相当于whichweighs【解析】【答案】A13、D【分析】略【解析】【答案】D14、D【分析】试题分析:考查非谓语动词。句意:受到这名年轻癌症患者勇气和意志力的感染,许多人在他的微博上留言,鼓励他与癌症抗争。people与inpress是动宾关系,即人们被他的事迹打动,应该用过去分词表示被动和完成,故选D。考点:考查非谓语动词【解析】【答案】D15、A【分析】考查固定句型。固定句型:It’snogooddoing句意:担心他的成绩是没有用的。故选B。考点:考查固定句型【解析】【答案】A16、C【分析】试题分析:考查形容词辨析。A活着的;B活着的;C活着的,现场直播的;D生动的,充满生气的。alive意为“活着”,既可指人,也可指物;可用来作表语,后置定语或宾补;living“活着”强调说明“尚在人间”,“健在”,作定语或表语。live“活着的”,通常指物,作前置定语;还指“实况转播的”。lively“活泼的”可作定语、表语或宾补。根据语义可知C选项正确。句意:今晚将有足球比赛的电视现场报道,我们可以一起观看。考点:考查形容词辨析。【解析】【答案】C17、C【分析】试题分析:考查介词的宾语从句,根据上下文意思:--我们到周末可以把事情准备好吗?--这要取决于是否能得到Green先生的合作。介词on后面是宾语从句,what引导宾语从句的时候,要在宾语从句中做主宾表,if不能和介词连用,that从句意上不通。选C。考点:考查介词的宾语从句【解析】【答案】C18、C【分析】试题分析:考查句子时态的使用。这是一个and引导的主从复合句。前面的部分是一个完整的句子,所以要有主语和谓语。并且不需要连词再来连接。且由这个句子判断可知,前面的主句是一个过去进行时态。句意:当我正在安静的街道上以每小时40公里的时速行驶时,一位老人突然在我面前闯过马路。故选C。考点:考查句子时态的使用【解析】【答案】C三、单句改错(共8题,共16分)19、略

保护某人以免遭。
本题题型为单词填空.在选择给定词语时,再考虑大意的前提下,还应该注意句子所用的时态,以及所填写的词在句子中的位置.通过这些判断,适当改变词汇形式,以符合题目要求.【解析】保护某人以免遭25、略
