A.to stop B.stopping C.to have stopped D.having stopped 错因分析 考生做本题时很容易受思维定式的影响,误选A项。分析句意可知,此处“only...”部分并不表示意外或不愿看到的结果。实际上,“only...”部分在句中作伴随状语,由于句子的主语“The workers”与设空处所填的非谓语动词之间为主谓关系,故选项B为正确答案。 [得分笔记] 平时我们最常见的是only to do sth.结构,如:He hurried to the station only to find that the train had left.。 only to do sth.这种结构在句中作状语时,常表示意外或不愿看到的结果,它所表达的事件往往是紧接着前面的事件发生的。 Ⅱ.完形填空 16.C [get与副词up搭配时,可以用作不及物动词,表示自己起床,也可以用作及物动词,表示使某人起床。] 17.A [fall asleep表示入睡的动作,而此处表示的是熟睡的状态,要用be fast/sound asleep,故选A项。] 18.A [下一句中的to the corner暗示了此题的答案。] 19.D [表示送信、送报时,用deliver。] 20.A [此处表示他用运货车来运送报纸,不强调方向,要用carry运送。] 21.D [根据语意,此处要用引导时间状语从句的连词,又因为“起床”是非延续性动词,所以用when。] 22.C [根据语境,此处要用和前面dark“黑暗的”相对的词light“明亮的”。] 23.C [route路线,路程,航线;road道路,公路;way路,特指去某处的路;path小径。] 24.A [protect...from意为“保护……免受”。] 25.A [选项中能接形容词作宾语补足语的动词只有make,且根据语意知此处应用v.ing作结果状语。] 26.C [此句中应用不可数名词work。] 27.C [文章第一句已经点明了比利是一名勤奋的学生,而且已经十四岁了,所以他应该是为上理想的大学而存钱。] 28.B [主语为人且后边的介词为on,此句采用的是spend money on sth.结构。] 29.B [此句讲的应该是他每月一次去收他的钱(money)。] 30.C [fulfilled满足的,此处表示拿到工资时的一种满足感。] 31.C [“get+过去分词”构成的被动语态,此空中的词修饰动词,应该用程度副词greatly,表示“大大地”。] 32.D [too可以用作程度副词,修饰表示情感的形容词,这时too相当于very,意为“非常”。willing乐意的,符合语境。] 33.D [根据空后的介词about可知,应该用形容词happy。] 34.C [从后边的as possible可看出,此句采用的是as...as结构,又因为customers为可数名词复数,所以此处选many。] 35.B [表示“如果是那样/这样的话”时,常用if so,in that/this case这样的表达。] 得分策略 完形填空题型的做题顺序是什么? 做完形填空题时,千万不要读一句填一空,因为完形填空题里所给的大多数选项填入单句后都可成立,但从全文看却不可取,且边看边做将无法形成连贯的思路,势必会影响对全文大意的整体理解。 我们认为,可取的做题程序应是: 1.先整体通读:读出文章的中心,读出文章的导向或作者的基本态度。通读时重点读首句或首段,读完首段后可先读尾段,再迅速浏览文章其它部分。 2.以段为单位,按段精读,按段理解,按段做题。具体做题时,考生应抓住段落的主题句,理解段意,一定要弄懂设空句子的意思,然后从词法、句法、行文逻辑等方面解题。 Ⅲ.阅读理解 36.C [细节理解题。根据Teens Go Online部分中的“The study covered...”可知,文中没有提到Sweden,所以C项为正确答案。] 37.D [细节理解题。结合School Soldiers部分中的“The activity is seen...”可知,政府要求他们进行军训是为了培养他们的爱国热情。] 38.B [细节理解题。Orlando ________这一部分中的“Of course,their teachers and...”说明他们是通过网络学习的,故其新闻标题为“奥兰多网上学校”最佳。] 39.C [是非判断题。根据The Florida High School这一部分中的“The state’s only online school...”可知,C项的意思和文意相符。] 40.A [段意归纳题。根据标题Chat to the Magic Mum及文章的相关内容可知,J.K.Rowling要进行一次网络访谈。] 得分策略 阅读理解文章中的生词比较多,该怎么处理? 一、略过生词 所谓略过生词并不是简单地将不认识的单词跳过,而是要尽快地判断出哪些生词是可以跳过而不影响理解文章的,哪些生词是不能轻易跳过并且需要进一步采取别的办法去处理的。 二、学会只猜测生词的大概意思,而不必追求其准确含义 [经典例题] The Asian gibbon,like other apes,especially adapts to life in trees. 解析 在这句话中,考生只要猜出gibbon是apes(类人猿)中的一种就够了,没必要知道其准确意思。 三、利用语法结构 这里谈的仅仅是语法分析对于理解生词的帮助,单凭语法分析,不可能确定一个词的准确意思,但它至少可以帮助判别一个词的词类。 [经典例题] The major points of your plan are clear to me,but the details are still hazy. 解析 根据but转折结构可猜测hazy和clear意思相反,故hazy的意思应为“模糊的,朦胧的。” 四、利用猜词法来猜测词义 1.即使生词超纲,根据上下文也能得出其大意。 2.即使一个词我们非常熟悉,也要通过上下文得出其所在特定场合的意思。查看更多
