My friends walked me to the bus stop and waited with 63 (I) until the bus arrived. I got on the bus and found a seat near the back, and then I noticed a man 64 (sit) at the front. He pretended that a tiger toy was real and giving it a voice. He must be 65 (mental) disabled. Behind him 66 (be) other people to whom he was trying to talk, but after some 67 (minute) he walked away and sat near me, looking annoyed. I didn’t want 68 (laugh) at for talking to him but I didn’t like leaving him on his own either. After a while I rose from my seat and walked to the front of the bus. I sat next 69 the man and introduced myself. We had 70 amazing conversation. He got off the bus before me and I felt very [来源:学科网]happy the rest of the way home. I’m glad I made the choice. It made both of us feel good. 【参考答案及难点解析:】 61. went 62. because 63. me 64. sitting 65. mentally 66. were 67. minutes 68. to be laughed 69. to 70. an 62. because 考查连词。句意:我很早就离开了,因为那天的晚些时候我和别人有一个约会。根据句意可知上下文之间是因果关系,所以使用because引导原因状语从句。 63. me 考查代词。句意:我的朋友和我一起走到公交车站并和我一起等到公交车来。根据句意可知我的朋友和我一起在等待。所以使用me作为with的宾语。 64. sitting 考查非谓语动词。本句中动词notice的宾语是a man,该宾语和动词sit构成主动关系,所以使用现在分词短语在句中作宾语补足语,对宾语进行补充说明。 65. mentally 考查副词。本句中使用副词mentally做状语修饰形容词disabled,而形容词通常在句中作表语或者定语,修饰名词,不能做状语修饰形 容词的。 66. were 考查倒装句。本句 是一个全部倒装句,真正的主语是横线后面的名词other people,这是一个复数名词,做主语的时候谓语动词使用复数形式,而本文又是一般过去时的时态,故were正确。 67. minutes 考查名词单复数。名词minute是一个可数名词,前面有some修饰,说明要使用复数形式。 68. to be laughed 考查不定式用法。动词短语want to do sth想要做某事;句意:我不想因为和他说话而被嘲笑。所以使用不定式的被动语态to be laughed。 69. to 考查介词短语。固定短语next to...在...旁边;我坐在他的旁边,做了自我介绍。 70. an 考查冠词。横线后面的名词conversation对话,这是一个可数名词,前面有形容词amazing修饰,所以使用an修饰,表示泛指。 [二] People do have different ideas about what __61___(wear). While young people tend to consider more about fashion, personality and how they look when 62 (choose) clothes, elderly people pay 63 (great) attention to whether they appear right, they feel comfortable as well as whether the material is worth 64 price. How people get dressed also changes over time. Take China 65 an example. In the 1960’s and 1970’s, there were practically only two or three colors people wore-blue, green and gray. The styles of the clothes 66 (be) also very dell. In the 1980’s young people would only wear 67 was in fashion. 68 (recent), we have come to understand that the way you dress 69 (you) is a reflection of your occupation, your background and your personality. So we see different people wear different clothes according to occasions, their likes and 70 (feel). 【参考答案及难点解析:】 61. to wear 62. choosing 63. greater 64. the 65. as 66. were 67. what 68. Recently 69. yourself 70. feelings 试题分析:本文属于说明文,告诉我们人们穿不同的衣服,是因为他们各自不同的职业、背景和个性。 61. to wear 考查不定式用法。“不定式可以+特殊疑问词”充当主语、宾语、表语或定语。本句中what to wear作为介词about的宾语。句意:人们对于穿什么衣服有不同的观点。 62. choosing 考查现在分词。本句中的动词choose与句子主语young people构成主动关系,所以使用现在分词在句中作状语,本句中的when是可以省略的。另外我们还可以理解成是省略句,在when后面省略了they are。 63. greater 考查比较级。本句把老年人和年轻人进行比较,发现老年人更注意自己的穿着。所以使用比较级greater。 64. the 考查冠词。在高中英语中通常使用定冠词the表示特指,本句中的the price特指所穿的衣服的价格。 65. as 考查固定搭配。短语take sth as an example以...为例;人们怎么穿衣服随着时间在变化。以中国为例...接下来就列举了中国人穿衣的习惯随着时间的改变而改变。 66. were 考查时态。本句是在叙述60、70年代中,中国人穿衣的情况,所以使用一般过去时。 67. what 考查宾语从句。本句中what引导起宾语从句,并在句中作主语。句意:在80年代,年轻人只穿流行的衣服。 68. Recently 考查副词。本句中副词recently近来,在句中作时间状语,句子使用现在完成时。形容词recent通常做定语修饰名词,不能做状语。句意:近来,我们已经逐渐理解你给自己穿衣的方式是你的职业、背景和个性的反映。 [三] Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Now American researchers think they are close to developing a pill, 61 will help people forget bad memories. The pill is designed to 62 (take) immediately after a frightening experience. They hope it might reduce, or 63 (possible) erase(抹去) the effect of painful memories. In November, experts tested a drug on people in the U.S. and France. The drug stops the body 64 (release) chemicals that fix memories in the brain. So far, the research 65 (suggest) that only the emotional effects of memories may be reduced, not that memories are wiped out. They are not sure to 66 degree people’s memories are affected. The research has caused a great deal of 67 (argue). Some think it is a bad idea, while others support it. Supporters say it could lead to pills which prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories. 68 , those who are 69 the research say that maybe the pills can change people’s memories and changing memories is very 70 (danger) because memories give us our identity. 【参考答案及难点解析:】 61. which 62. be taken 63. possibly 64. releasing65. has suggested 66. what 67. argument 68. However69. against 70. dangerous 62. be taken 考查语态。本句的主语the pill与动词take之后构成被动关系,所以使用被动语态。句意:在可怕的经历发生以后药片要立刻被服用。 63. possibly 考查副词。在英语中副词通常做状语用来修饰形容词、副词或动词。本句中分词possibly修饰动词短语ease the effect of painful memories.句意:他们希望这种要求也许减少或可能抹去痛苦的记忆的影响。 64. releasing 考查固定搭配。动词短语stop sb/sth (from) doing sth阻止某人做某事,其中的介词from可以省略。句意:这种药物阻止时态释放让大脑记忆的物质。 65. has suggested 考查时态。本句的时间状语是so far“到目前为止”,该时间状语通常和现在完成时连用。 66. what 考查宾语从句。本句中宾语从句to what degree people’s memories are affected 一起作为形容词sure的宾语,句中what放在名词degree前面引导这个宾语从句。句意:他们不确定人们的记忆被影响到何种程度。 67. argument 考查名词。横线前面有介词of说明横线上应该使用名词充当介词of的宾语。而argue的名词形式为argument。 68. However 考查连词。横线前句:很多人遭受可怕记忆的影响,所以这种药物对他们是有好处的。但是反对这项研究的人说这种药物可能会改变人们的记忆。上下文之间是转折关系,所以使用however表示转折,该词前后都要有逗号隔开。 69. against 考查介词。根据前后句意可知本句叙述的是否定这一药物的人的观点,所以使用介词against表示“反对”。 70. dangerous 考查形容词。因为记忆给了我们身份,正是因为我们有了记忆我们才知道自己是谁,现在这种药物改变了我们的记忆,那么对我们来说是很危险的。形容词dangerous与系动词is连用,构成系表结构。 [四] I always have my own ways to learn English.
