9大语法难点(1)一、宾语从句1.宾语从句的含义充当主句宾语的从句叫做宾语从句。

如:She knew that the teacher had se en the film.她知道这位老师看过这部电影。

“that the teacher had seen the film”做 knew 的宾语,同时又是由连接词 that 引导的从句,所以它叫做宾语从句。

2. 宾语从句的分类(1)动词宾语从句:顾名思义,它是位于动词后面的宾语从句。

如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。

(2)介词宾语从句:顾名思义,它是位于介词后面的宾语从句。

如:I agree with what you said just now.我同意你刚才说的话。

(3)形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。

如:I am afraid that I will be late. 恐怕我要迟到了。

3. 引导宾语从句的连接词(1)that:没有含义,在宾语从句中不做成分(2)whether/if:表示是否,在宾语从句中不做成分。

I don't know if /whether he still lives h ere after so many years. 我不知道这么多年后,他是否还住在这里。

(3)连接代词:what, which, who, whom, whose(在宾语从句中做主、宾、表和定语)连接副词:where, when, how, why(在宾语从句中做状语)The small children don't know what is in their stockings.(what 在宾语从句中做主语)这些小孩子不知道什么在他们的长筒袜里。

Could you tell me why you were late for the meeting this morning?(why 在宾语从句中做原因状语)你能告诉我为什么你今天早上开会迟到吗?4. 在做宾语从句的题目时应注意两点(1)时态:①当主句是现在时态时,宾语从句可以根据需要使用任何时态。

但是我们也应认真思索,为什么我们可以这么轻易地把爱韩剧就等于汉奸、看国产片就等于爱国的逻辑理直气壮地宣之于口,而且竟还有市场?很多人之所以能够不假思索地说出这种话,是因为近年有一股更大的潮流,这股潮流就是“消费型民族主义”。

首先,我们要注意它与抵制日货的理路不尽相同。

不管你同意与否,提倡抵制日货的人至少还试图搬出一套罢买日货可以打击日本商界,然后日本企业会抱怨日本政府外交政策的推理。

“消费型民族主义”却是诉诸感情直觉,要大家以抵制某产品的方式直接表达爱国情怀。

当然,实际操作起来,“消费型民族主义”又会和抵制日货运动相混杂,成为后者的指导精神。

其次,“消费型民族主义”不是一种经济政策上的保护主义。

奉行保护主义的国家如韩国,会硬性规定电影院每年要有一定日数放映韩片,以保证电影生产数量的稳定,以阻挡外来电影带来的竞争压力,目的是扶持自己国家的特定产业。

保护政策好还是不好,各有各的观点,但它起码也是套言之成理的说法。

“消费型民族主义”着眼的却不是这么深层次的产业发展问题,它只不过是一种浮浅的情绪表达和标签。

“消费型民族主义”的出现,靠的是两种逻辑。

一个是民族主义本身的空洞,另一个是市场营销的文化转向。

什么叫民族主义的空洞呢?难道民族主义不是很强大很澎湃的一种意识形态吗?的确,它是的。

但它之所以强大,之所以能够把一切事物都纳在民族旗号下,照研究民族主义的人类学家安德森的说法,正是因为它的内涵是空的。

举个例子,由于没有人能够肯定到底某物的民族性是什么,所以我们才能把一件衣服说成是很有民族性的,一部汽车是很民族的,甚至连一种动物也是很能代表某民族的(尽管他在血统上和这一民族无关,也不是这一民族培育出来的品种),没有什么不可以被命名为很民族的。

Sunday, October 29 , 2017BIt all started when I was 11 years old, when I had just got into the school. Everything was all right at the beginning and I even made a few friends.A few months later, however the school decided to organize a completely new class in order to make the classes smaller, because obviously that helped with learning and getting rid of bullying(消除欺凌). Yeah,that’s right !I was chosen to be moved from my old class to the new one. At first it was fine, everyone ignored me, and I was happy to be left alone. Then it started. One day after school a few students from my new class came up to me.“Hi,” a girl called Molly said, “Wanna be friends?”I said "Yes " of course. She laughed and told me that she was sorry but she and her mates couldn’t be friends with " loners " like me.A few more situations like that followed, but soon it turned physical. For a few weeks I was beaten up almost every day after school. When I told the teacher, she said I couldn’t change class and that was final. So I was stuck with those horrible students. I cried myself to sleep every night. But after a few more months of putting up with that, I decided to tell my family. They didn’t do anything at first, but after a while they got tired of me moaning(抱怨)about how I hated school and talked to the head teacher. A week or so after that I was moved to another class. They soon forgot about me.I’m perfectly(完全地;完美的) fine now. I hardly ever cry. And all this happened becauseI told someone who could actually do something.24. The author’s trouble began .A. as soon as she moved into a new schoolB. soon after she moved into a smaller classC. before she got to know a girl called MollyD.when she was about to move into a new school25. What do w e know about the author’s new school?A. It had more girls than boys in the school.B. It had students only from the local area.C. Bullying was common among students in the school.D. It was set up not long before the author moved in.26. What’s the author’s attitude(态度)t owards the school’s decision to make a new class?A. PuzzledB. SupportiveC. DoubtfulD. Unhappy27. When Molly said “Wanna be friends?, she was .A. trying to make fun of the authorB. trying to be friendly with the authorC. interested in making friends with the authorD. trying to get more information about the authorCEven if all goes well for you in high school—you keep your grades up,join in activities and never fall on your face in front of everyone in the dining hall—that time of life still can be hard. There are so many subjects to learn and social activities to join in. But of all different challenges, making good friends might be the most important.Researchers found that those with strong, close relationships with their friends at age 15 were more likely to be healthy and happy later. They have more self-worth(自信)and less anxiety and depressive symptoms (抑郁症状)by early adulthood(人). Importantly, popularity—explained as lots of people liking you generally, but not closely—wasn't found to have the same advantage as close friends.The researchers followed the 169 teens every year for ten years. They got data in real time from these teens as they grew. Importantly,too, the teens were 58 percent whites, 29 percent African Americans, and 8 percent of different faces, and with families of $40,000 to $59,999 a year.“Our study proves that forming strong close friendships is likely one of the most important pieces of the being well-liked by a large group of teenage social experience,” said Joseph Allen. Why does this matter? Because, as Allen wrote, “For high schoolers, people cannot replace developing deep and supportive friendships. And these experiences stay with us,over and above what happens later. As technology makes it increasingly easy to make many superficial(表面的)friends, spending time and attention in developing close connections(关系)with a few people should be a main concern.”28. According to the study, making good friends at high school will .A. help you believe in yourselfB. help you keep away from anxiety in lifeC. take away your symptoms of depressionD. make you experience more worry29. What do the numbers in paragraph 3 show about the research?A. It costs researchers a lot of money.B. It is scientific.C. It is carried out by teenagers themselves.D. It is made in both America and Africa.30. What can we learn from the last paragraph?A. High schoolers prefer to be liked by strangersB. Friendships have nothing to do with technology.C. True friendship calls for much energy.D. A few people can’t be a social net.31. What might be the best title for the passage?A. Friends Make a Difference to Your LifeB. Close Friendships Can Give You Strength in LifeC. Being Popular at High School Is Really ImportantD. Good High School Friends Add to Your Happiness LaterDDoes handwriting(书写,书法)matter?Not very much,according to many educators. However,scientists say it is far too soon to declare handwriting is not important.New evidence(证据)suggests that the link between handwriting and educational development is deep.Children not only learn to read more quickly when they first learn to write by hand,but they are also better able to create ideas and remember information.In other words,it's not only what we write that matters﹣but how.A study led by Karin James,a psychologist at Indiana University,gave support to that view. A group of children,who had not learned to read and write,were offered a letter or a shape on a card and asked to copy it in one of three ways:draw the image on a page but with a dotted outline (虚线),draw it on a piece of blank white paper,or type it on a computer.Then the researchers put the children in a brain scanner(脑部扫描仪)and showed them the image again.It was found that when children had drawn a letter freehand without a dotted outline or a computer,the activity in three areas of the brain were increased.These three areas work actively in adults when they read and write.By contrast(比较),children who chose the other two ways showed no such effect.Dr.James attributes(把…归于)the differences to the process(过程)of free handwriting:Not only must we first plan and take action in a way but we are also likely to produce a result that is variable.Those are not necessary when we have an outline.It's time for educators to change their mind and pay more attention to children's handwriting.32.What do scientists mean by saying " it is far too soon to declare handwriting is not important"?A.Handwriting is not very important to children.B.Handwriting has nothing to do with education.C.Handwriting should not be ignored at present.D.Handwriting can not be learned in a short time.33.What does "that view" in Para.3 refer to?A.Children read quickly when they write by hand.B.How we write is as important as what we write.C.Children create ideas and remember information.D.A group of students should know what to write.34.In the study led by Karin James, which child’s brain is the most actively?A. The children’s brains were equally active.B. The one who drew the image on a page but with a dotted outline(虚线).C. The one who typed the image on a computer.D. The one who drew the image on a piece of blank white paper.35. According to the passage,the author obviously giving up handwriting.A.is for B.is against C.is responsible for D.doesn't care about.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,并在答题卡上将该项涂黑。
