Long long ago, there lived two brothers in a village. Their parents died and left them a farm. The elder son took everything except for a very small piece of land, a cat and a dog. The younger son had to use the cat and the dog to pull his plough(犁) because he did not have an ox(牛). They did not like this at all and cried out.
Near the farm, there was a mountain called Stone Mountain. A demon(魔鬼) lived on this mountain and people who looked at it carefully could see his face.

Music was a constant presence in my childhood home. Sunday lunches, housework, homework, and afternoons in the garden. It was a rush of Van Morrison, Supertramp, Kate Bush and so on, and all three of us could sing their songs.
Some moments seem scored on my memory, my dad playing sixteen Candles on my birthday, a school morning with my mum as she played Phil Coll ins’s No Jacket Required. And when I stop to consider it now, I see how much music has shaped and strengthened my relationship with my parents.
I often think it was my mum who gave me lyrics(歌词), a delight in the sound, color and weight of words. My dad gave me music, jazz, blues and rock. He would take me to record markets, where I would stand quietly among the rows and listen to the beautiful music. He would make me CDs, send me messages about his latest favorite music, and greet my return home saying, “have you heard the new Kanye, Jame?”
My dad and I are still talking about music. When I went home recently, we sat at the kitchen table having supper while he explained what he loved about music. And when my parents went to see Bon Iver play in Manchester this autumn, he emailed me the following morning to express his feelings about the show.
It was my mum who introduced my dad to music. Some time around 1970 she bought a CD in Manchester and forced him to listen to it. Even since, music has been a support in our family.
60. The purpose of paragraph 1 is to show_______.
A. the author was fond of music.
B. the author’s family liked music.

C. the author’s mum played a very important role in making the author and her dad interested
in music.

Rough ly 70% of the earth’s surface covered with water is found in numerous lakes, rivers, seas, and oceans. Land covers the remaining30% of the earth’s surface.
It is impossible for people to live without water since there can be no life without water. It is a fact that a man can live without food for days, but without water he will surely die.
In drier parts of the world where there is not much rainfall, water is channeled from rivers and lakes to irrigate crops and trees which provide food for human beings. In many parts of these arid(干旱的)regions, cultivation(耕种)is not possible unless there is water.
But too much water in the form of floods can bring disaster to man. Floods, which result from heavy rains, are very common in many parts of the world.

When I was young, Mom was often sick and didn’t make much money. We seldom went anywhere special except at those times that some generous adults stepped in to brighten our horizons.
One of my favorite memories of my early years was when I was a second grade. My teacher, also my best friend’s aunt, took us two girls to a neighboring city for a day. While in the city that day, I remember seeing a beautiful show of Rudolph the Red-Nosed Reindeer books. I longed for the books. Of course, I couldn’t buy one—I only had a little pocket change. That day we rode an elevator and were taken to see a Disney movie after eating in a restaurant—it was a tiny unforgettable day.
Another time my aunt, a dry old woman who went out about as seldom as our family did, took me to the movie. I can’t remember the movie’s name but I do remember it was a unique experience to see a long movie on such a wide screen.
Other times, relatives took me to attend a carnival(狂欢节) or I was invited to a neighbor’s home to watch some musical program when TVs were not situated in every living room.
Had it not been for all those kind people allowing me to participate in their lives, I would have grown up completely ignorant(无知) of the world outside our little house and country school. Today, most children enjoy a variety of experiences. In our time it was different. It was only through the kindness of others that I was able to share in experiences I would otherwise never have had..
67. Why did the author seldom go anywhere when she was young?
A. It was not safe for the girls to go out.
B. The transportation was not convenient.
C. Her family couldn’t pay for her travel. C. Her parents were afraid that she would get lost
68. Who has ever taken the author to watch the book on show?
A. Her aunt
B. A teacher
C. A neighbor
D. Her parents
69. What does the underlined word “situated” in the fourth paragraph probably mean?
A. Laid
B. Watched
C. Gained
D. Settled
70. What does the author mainly want to tell us in the last passage?
A. Most children today enjoy their life at home.
B. The life in the past is poor and terrible,
C. The people in the past are ignorant.
D. The author felt grateful to the kind.

We all want to grow up happily and healthily, and for this goal we must do several things. Firstly, we should develop a good attitude to life. Life consists of not only sunshine but also hard times. We should be brave in front of difficulties. Secondly, we must study hard because knowledge is power. If we have the power, we can help to build our country and enjoy life better.
In order to study well, we need to do sports so that we can keep fit. We can go running, play ball games or simply take a walk after a day’s study. By the way, we also should have a balanced diet to keep us fit and healthy.
I am sure if we do above those things well, we will be able to grow up happily and healthily.

极坐标高考题的几种常见题型 贵州省册亨民族中学(552200) 韦万祥 和直角坐标系一样,极坐标系是常用的一种坐标系,极坐标是历年理工类高考 必考的内容,随着新课程改革的深入,在2007年4个省市新课标高考试题中有3 个省市考查了极坐标.涉及较多的是极坐标与直角坐标的互化及简单应用.多以选 择题、填空题形式出现,以考查基本概念,基本知识,基本运算为主,一般属于容易 题. 一、极坐标方程与直角坐标方程的互化 互化条件：极点与原点重合，极轴与x 轴正半轴重合，长度单位相同. 互化公式：???==θρθρsin cos y x 或 ?? ???≠=+=)0(tan 2 22x x y y x θρ θ的象限由点(x,y)所在的象限确定. 例1(2007海南宁夏)⊙O 1和⊙O 2的极坐标方程分别为θρcos 4=，θρsin 4-=． (I)把⊙O 1和⊙O 2的极坐标方程化为直角坐标方程； (II)求经过⊙O 1，⊙O 2交点的直线的直角坐标方程． 解：以极点为原点，极轴为x 轴正半轴，建立平面直角坐标系，两坐标系 中取相同的长度单位． (I)θρcos =x ，θρsin =y ，由θρcos 4=得θρρcos 42=．所以x y x 422=+． 即0422=-+x y x 为⊙O 1的直角坐标方程． 同理0422=++y y x 为⊙O 2的直角坐标方程． (II)解法一:由???=++=-+0 4042222y y x x y x 解得???==0011y x ，???-==2222y x 即⊙O 1，⊙O 2交于点(0,0)和(2,－2)．过交点的直线的直角坐标方程为y=－x ． 解法二: 由???=++=-+0 4042222y y x x y x ,两式相减得－4x-4y=0,即过交点的直线的直角坐标方程为y=－x ． 评述:本题主要考查曲线的极坐标方程化为直角坐标方程的方法及两圆公共弦所 在直线方程的求法. 例2(2003全国)圆锥曲线θ θρ2cos sin 8=的准线方程是 (A)2cos -=θρ (B)2cos =θρ (C) 2sin -=θρ (D) 2sin =θρ 解: 由θ θρ2cos sin 8=去分母后两边同时乘以ρ得:θρθρsin 8cos 22=,所以x 2=8y ,其准线方程为y=2-,在极坐标系中方程为2sin -=θρ,故选C.
