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。

2018-2019学年安阳市二中高二年级第一次月考英语试卷第I卷第一部分阅读理解(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的四个选项(A 、B 、C 和D )中,选出最佳选项,并在答题卡上将该项涂黑。
AReading poems can be a lot of fun for kids. With these children's poetry books, children will gain a new appreciation for poetry and the spoken word.Joyful Noise: Poems for Two VoicesThe entertaining sounds of insects fill these poems by Paul Fleischman, making it a favorite with 12-15-year-olds. These poems were written to be read aloud by two readers.Paul Fleischman received the John Newbery Medal for young people's literature for the book in 1989. Other recognition included: Boston Globe-Horn Book Award Honor Book, ALA Notable Children's Books list and so on.Eric Beddow's artwork, full page, detailed pencil pictures, are vivid and effective complements to the poetry, which brings insects to life when read aloud by two voices.You Read to Me, I'll Read to You: Very Short Stories to Read Together Poet Mary Ann Hoberman is the author of the picture book, which includes the joyful pictures of Michael Emberley. The book contains very short story poems for two people to read aloud, alternately and together. Each of the 12 stories for 6-11-year-olds features rhythm, rhyme, and repetition, as well as humor and attention on the joys of reading.The book is one of a series of story poems. All the books are designed to be read aloud by two people, as if, says Hoberman, it's “a little play for two voices.” The two people can be an adult and a child or two children.Big Talk: Poems for Four VoicesPoems for four voices are much more challenging to present than poems for two voices, but middle school students tend to enjoy the challenge. The three-story poems in itwill appeal to middle schoolers. The author, Paul Fleischman, provides a clear description of how to use the book. The poems are color-coded to make them easier for the four readers to keep track of their parts.I Am Phoenix: Poems for Two VoicesThe fifteen poems for two voices in the book are all about birds. Ken Nutt's soft pencil pictures complement the poems by Paul Fleischman. The words of each poem are in two columns, each to be read by one person, sometimes individually, sometimes together.1.Which book is written for primary school students?A.

I shook my head stubbornly — and felt the ache in my tooth.I'd thought I could hold out till my dentist came back from holiday, but the pain was really unbearable.I started calling the dentists in the phone book, but no one could see me immediately.Finally, at about lunchtime, I got lucky."If you come by right now," the receptionist said, "the dentist will fit you in."I took my purse and keys and rushed to my car.But suddenly I began to doubt about the dentist.What kind of dentist would be so eager to treat someone at such short notice? Why wasn't he as busy as the others?In the dentist's office, I sat down and looked around.I saw nothing but the bare walls and I became even more worried.The assistant noticed my nervousness and placed her warm hand over my ice-cold one.When I told her my fears, she laughed and said, "Don't worry.The dentist is very good.""How long do I have to wait for him?" I asked impatiently."Come on, he is coming.Just lie down and relax.And enjoy the artwork," the assistant said."The artwork?" I was puzzled.The chair went back.Suddenly I smiled.There was a beautiful picture, right where I could enjoy it: on the ceiling.How considerate the dentist was!

Most Asians immigrate because they believe that they can give their children a better education in the West. In Asia, especially in China, Japan, and Korea, it is difficult to go to university. Students must pass the strict national examination. However, in Canada and the United States, it is easy to go to university, and anyone who wants to go can go. As a result, Asian parents decide to leave their countries so that their children can go to university.The problem is that when Asians arrive, they discover that finding a job and making money are more difficult in the West than in the East. Also, they find that they are very lonely, and that they miss their homes. Because of these two reasons, most Asian parents decide to go back to work while their children study in the West. Therefore, these children become "satellite kids", and most of their parents do not know how sad it is to be a "satellite kid".Recently Canadians and Americans discovered the "satellite kid" problem. Because these children do not speak English well and their parents are not there to take care of them, they are often absent from school. To be a "satellite kid" means growing up in a country where you know you are different and where you cannot make friends because you do not speak English well. Also, it means growing up lonely, because your parents are elsewhere. What these "satellite kids" will probably say to their parents is that it's better to have parents around than to have a university education. 8.Some Asian parents send their kids abroad because .A. they hope their children may easily find a job thereB. the kids may not be accepted by universities in their own countriesC. all foreign universities are better than the ones in their own countriesD. the kids want to improve their English and make foreign friends9."Satellite kids" refer to Asian kids .A. without parentsB. living abroad aloneC. with university educationD. speaking no English10.Some Asian immigrant children become "satellite kids" because their parents .A.want to leave their own countriesB.want them to go to universityC.return to their countries to workD.want them to be independent11.What is the main idea of the passage?A.Parents want better education for their kids.B.Parents feel lonely and miss their families.C.Canadians and Americans begin to notice the "satellite kid"problem.D.Kids in foreign countries alone are badly in need of care from their families.DIn mid-November of 1963, an island was born in the North Atlantic, some 20 miles off the southwestern coast of Iceland. It had given only one sign of its coming. For three days, farmers on the neighboring Vestmann Islands had noticed a bad smell in the air like the odor of rotten eggs.Early on the morning of November 14, the captain of an Icelandic fishing ship saw black columns erupting from the sea through his telescopes. He suspected that he was seeing a volcano rising from the ocean. The hours that followed proved him right. He was watching the volcanic eruption that built the island later named Surtsey.Some days earlier, a volcano had started to erupt 425 feet below the surface of the sea. It poured out gases and volcanic ash and cinder. They began to build a mountain. By the morning of November 15, the top of the volcano was 33 feet above the water and stillgrowing rapidly. Columns of smoke and gases rose two miles into the air. Violent eruptions continued through the winter. In April 1964, the violent eruptions stopped, and lava began to flow. Surtsey,it seemed, had come to stay.To earth scientists and to biologists, Surtsey was endlessly fascinating. It offered a chance to study a new volcano and to see new land take shape. Earth scientists hoped that by studying what was happening to Surtsey, they would gain a better understanding of the forces behind its growth.Surtsey rose from a huge underwater mountain range that runs down the middle of the Atlantic Ocean and is called the Mid-Atlantic Ridge. The ridge is the center of many earthquakes, and it is highly volcanic. Here and there its volcanic action has built mountains that thrust(猛推)through the surface of the ocean, creating small islands such as Surtsey. Long ago vast outpourings of lava from the ridge built the big island of Iceland.The ridge, however, is much more than a builder of islands. It is a sign of powerful forces at work within the earth. Many earth scientists are certain that these same forces are builders of continents and mountains and are the cause of the earthquakes and volcanic eruptions. They see the ridge as a key to understanding the most basicsecrets of the earth. These forces helped to shape our planet when it was young, to give it land and sea and air, and so to make it the kind of planet where life could develop.12.What was the very first sign of Surtsey?A.Some smoke.B.Explosions.C.An unusual smell.D.A violent storm.13.What do we know about Surtsey?A.It is a huge underwater mountain range.B.It is located 20 miles off Vestmann Islands.C.It took Surtsey almost one year to come into being.D.It was produced by the strong forces within the earth.14.Why is studying Surtsey important to scientists?A.It tells more about the formation of the earth.B.It warns people of dangerous volcanic eruptions.C.It leads to the discovery of new energy sources.D.It helps predict when new islands will be formed.15.What is the passage mainly about?A.How an island was born.B.Where Surtsey rose from.C.What are the secrets to volcanic eruptions?D.Why the Mid-Atlantic Ridge is important.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。
