A C选项是特称命题，细化分析B选项存在一个3a=使得函数是增函数，所以B选项也是存在命题. D选项是全称命题.【详解】全称命题是含有全称量词的命题，全称量词有所有，任意，每一个.A C选项含有存在量词：存在，所以是特称命题，B选项存在一个3a=使得函数是增函数，所以B选项也是特称命题. D选项所有的平行四边形都不是正方形，所以是全称命题.故选：D.2．C【分析】利用含有全称量词的命题为全称量词命题对①①①逐个进行分析，即可得到结果.【详解】命题①含有全称量词，为全称量词命题；命题①含有存在量词，为存在量词命题；命题①可以叙述为“每一个三角形的内角和都是180°”，为全称量词命题．故有2个全称量词命题．故选:C．3．B【分析】判断每个命题的量词，即可判断选项.【详解】A含有全称量词①，为全称量词命题，B含有存在量词①，为存在量词命题，满足条件．C省略了全称量词所有，为全称量词命题，D 省略了全称量词所有，为全称量词命题.故选：B ．4．C【分析】根据全称量词命题和存在量词命题的定义即可得到答案.【详解】根据全称量词和存在量词命题的定义可知，A ，B ，D 是存在量词命题，C 是全称量词命题． 故选：C.5．D【分析】利用全称量词的定义，分别判断选项.【详解】A.实数都大于0，是全称量词命题，假命题；B.梯形两条对角线相等，是全称量词命题，假命题；C.有小于1的自然数，是特称命题，真命题；D.三角形的内角和为180度，是全称量词命题，真命题.故选：D6．A【分析】由已知得P Q ⊆，再依次判断选项.【详解】因为非空集合P ，Q 满足P Q Q ⋃=，所以P Q ⊆，对于AC ，由子集的定义知P 中任意一个元素都是Q 中的元素，即x P ∀∈，x Q ∈，故A 正确，C 错误； 对于BD ，由P Q ⊆，分类讨论：若P 是Q 的真子集，则∃∈x Q ，x P ∉；若P Q =，则x Q ∀∈，x P ∈；故 BD 错误．故选：A ．7．B【分析】根据等比数列定义结合对命题①，①，①的题设条件进行分析即可判断作答.【详解】对于①，题设条件与等比数列定义相一致，①正确；对于①，满足题设条件的a ，b ，c 值有a =b =0或c =b =0或a =b =c =0之一发生时, a ，b ，c 不成等比数列； 对于①，满足题设条件的q=0时，{an }不是等比数列，即命题①，①，①中，只有①是正确的命题.故选：B8．∀n ①N *，13+23+33+…+n 3＝（1+2+3+…+n ）2【分析】观察到从1开始加，连续的几个数的三次方相加，就得其和的三次方，总结一下就是：任意从1开始的连续n 个整数的三次方和等于其和的三次方.【详解】解：根据已知条件的规律结合13＝12可得：∀n ①N *，13+23+33+…+n 3＝（1+2+3+…+n ）2.故答案为：∀n ①N *，13+23+33+…+n 3＝（1+2+3+…+n ）29．{}3m m ≤【分析】由题可得B A ⊆，然后分类讨论根据集合的包含关系即得.【详解】由于命题:p x B ∀∈，x A ∈是真命题，所以B A ⊆,当B =∅时，121m m +>-，解得2m <；当B ≠∅时，12112215m m m m +≤-⎧⎪+≥-⎨⎪-≤⎩，解得23m ≤≤，综上，m 的取值范围是{}3m m ≤． 故答案为：{}3m m ≤．10．3【分析】由题意可知命题的否定是真命题，从而可求出a 的取值范围，进而可求得a 的最小值【详解】“[]01,1x ∃∈-，020x a +->”的否定为“[1,1]x ∀∈-，都有20x a +-≤”，因为“[]01,1x ∃∈-，020x a +->”为假命题，所以“[1,1]x ∀∈-，都有20x a +-≤”为真命题，所以2a x +≥在[1,1]x ∈-上恒成立，所以3a ≥，所以实数a 的最小值为3，故答案为：311． （1）（2）（3） （4）【分析】利用全称量词命题和存在量词命题和定义判断即可【详解】（1）表示所有的正方形，所以是全称量词命题，（2）含有全称量词，所以是全称量词命题，（3）表示所有的正数，所以是全称量词命题，（4）含有存在量词，所以是存在量词命题，（5）不是命题，故答案为：（1）（2）（3），（4）12．（1）全称命题；∀m＞1，方程x2﹣2x+m＝0无实数根；（2）特称命题；∃一对实数x，y，使2x+3y+3＞0成立；（3）特称命题；∃一个三角形没有外接圆；（4）全称命题；∀x①R，x2≥0.【分析】根据全称命题和特称命题的定义进行逐一求解即可.【详解】解：（1）任意的m＞1方程x2﹣2x+m＝0无实数根，是一个全称命题，用符号表示为：∀m＞1，方程x2﹣2x+m＝0无实数根；（2）存在一对实数x，y，使2x+3y+3＞0成立，是一个特称命题，用符号表示为：∃一对实数x，y，使2x+3y+3＞0成立；（3）存在一个三角形没有外接圆，是一个特称命题，用符号表示为：∃一个三角形没有外接圆；（4）实数的平方大于等于0，是一个全称命题，用符号表示为：∀x①R，x2≥0.13．（1）是全称命题；（2）不是命题；（3）是特称命题；（4）是特称命题．【分析】（1）根据题中包含的全称量词可确定为全称命题；（2）根据命题的概念即可确定答案；（3）根据题中的描述可确定为特称命题；（4）根据题中的描述可确定为特称命题.【详解】解：对于（1），任何一个实数除以1，仍等于这个数，是命题，且是全称命题；对于（2），三角函数都是周期函数吗？不是判断句故不是命题；对于（3），有一个实数x，x不能取倒数，是命题，是特称命题；对于（4），有的三角形内角和不等于180 ，是命题，是特称命题．14．(1)全称量词命题，且是真命题(2)是存在量词命题，是真命题(3)是全称量词命题，假命题【分析】（1）（2）（3）根据特称命题和全称命题的定义判断即可．（1）命题中隐含了全称量词“所有的”，所以此命题是全称量词命题，且是真命题．（2）命题中含有存在量词“至少有一个”，所以此命题是存在量词命题，举例99既能被11整除，又能被9整除，所以是真命题．（3）命题中含有全称量词“∀”，所以此命题是全称量词命题， 因为当x ＝1时，x 1x+=2，所以命题是假命题． 15．真命题，证明见解析【分析】直接配方化简即得解.【详解】解：是真命题，证明如下：因为222a b c ab bc ca ++=++，所以2220a b c ab bc ca +--+-=，所以()()()2220a b b c c a -+-+-=，所以0a b -=，0b c -=，0c a -=，即a b c ==．所以ABC 为等边三角形．所以原命题是真命题.。

She 35 one day being able to fly and see the 36 forest from up high. 37 , that dream was gone after a great fire.When the fire was 38 put out, all that was left of the trees were stumps（树桩）.39 plants and animals that had live there were gone. The stone bird was the only one that didn’t 40 in the fire. When she saw what had 41 to the trees, she felt very sad. Looking at the burnt trees, she couldn’t 42 crying. She cried for hours and days. She cried with such a feeling that her 43 were wearing away her stone 44 . Finally all her body was worn away and the bird had 45 some water.But when the 46 came out, the water rose into the sky and became a happy little cloud which could fly over the trees and see everything 47 .Since then, the little cloud has traveled all over the world.

Or in a waiting room full of strangers? Or on a bus? Researchers have found out some interesting facts.Perhaps unsurprisingly, we prefer to sit closer to people like ourselves. Girls sit by girls and boys sit by boys. Adults sit together and young people choose another young person to sit near. But it goes further than this. We even choose to sit near someone who looks like us. People with glasses are more likely to sit near other people with glasses. People with long hair sit closer to other people with long hair.We seem to believe that people with similar habits or hobbies will share similar attitude and we are more likely to be accepted by people like ourselves or even, we think we may be safer with people who look like us. Sometimes that’s true but it's a pity if we always stick to the same people, the same group. The danger in always staying in our comfort zone (舒适区)is that we just recycle the same opinions, the same tastes and the same ideas. We lose the chance to learn something new, find out about interesting things, hear funny stories and discover difference. When we always stick to the same people, how can we ever break down the barriers which prevent us from getting to know people with different ideas? And how can we avoid the ignorance (无知),which too often leads to prejudice (偏见) and even fear? If instead you want to live in a society that opens to changes and new things and different opinions, be the cat among the pigeons.Move out of your comfort zone. Go and sit next to someone different. And don't just sit there in silence. Say hello. Ask a question. Start a conversation. That’s how we make friends. That’s how we learn about people. That’s how we open our minds to new ideas. That's how we live an exciting life.66. From the passage, we know that people prefer sitting by someone whoA. is like themselvesB. has a sense of humor C. is open-mindedD. lives an exciting life67. People like staying in their comfort zone because they mayA. remain comfortable and specialB. be accepted easily and feel safeC. find out more interesting thingsD. discover differences among themselves68. What is the purpose of the passage?A. To tell us just to be ourselves in social life.B. To introduce ways to learn about the world.C. To explain how people communicate with others.D. To encourage us to meet people of different kinds.Passage 2Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk , laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named this way. So are some schools. We think of these people when we go to these places.There's more good news for people, if they have friends. These people live longer than those people if those don't have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that someone cares, if someone cares about you, you take better care of yourself.56. The first paragraph tells us __________.A. we always need friends around usB. none needs friendsC. making friends is the need in people's lifeD. we need to be alone57. Which of the following is what the writer doesn't say in the passage?A. People are happy when their friends leave them.B. People may never see their friends after their friends move away.C. People can know their friends in different ways.D. People like their friends very much if they get to know them.58. Which of the following is the most probable place people name after friendly people?A. A house.B. A room.C. A library.D. A village.59. If people have friends, they would live longer, because __________.A. they feel happier and healthierB. they get a lot of help from their friendsC. they take better care of themselvesD. both A and C60. This passage tells us __________.A. that people are all friendsB. that people need friendsC. how to get to know friendsD. how to name a placePassage 3Many teenagers feel that the most important people in their lives are their friends. They believe that their family members don't know them as well as their friends do. In large families, it is quite often for brothers and sisters to fight with each other and then they can only go to their friends for some ideas.It is very important for teenagers to have one good friend or a group of friends. Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication is very important in children's growing up, because friends can discuss something. These things are difficult to tell their family members.However, parents often try to choose their children's friends for them. Some parents may even stop their children from meeting their good friends. Have you ever thought of the following questions?Who chooses your friends?Do you choose your friends or your friends choose you?Have you got a good friend your parents don't like?Your answers are welcome.61. Many teenagers think that _____ can understand them better.A. friendsB. brothersC. sistersD. parents62. When teenagers have something difficult to tell their parents, they usually____.A. stay alone at homeB. fight with their parentsC. discuss it with their friendsD. go to their brothers and sisters for help63. The sentence "Your answers are welcome." means ____.A. you are welcome to discuss the questions with usB. we've got no idea, so your answers are welcomeC. your answers are always rightD. you can give us all the right answers64. Which of the following is the writer's attitude?A. Parents should choose friends for their children.B. Children should choose everything they like.C. Parents should understand their children better.D. Teenagers should only go to their friends for help.65. When teenagers stay alone, the usual way of communication is to ____.A. go to their friendsB. talk with their friends on the phoneC. watch TvD. have a discussion with their parentsPassage 4应用文（细心做，要争取全对）The National Gallery Description:The National Gallery is the British national art museum built on the north side of Trafalgar Square in London.

But soon, the importance of English idioms was shown in an amusing experience.One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished(惊讶). Gently shaking his head，shrugging（耸）his shoulders, he said，“You don’t say!” “You don’t say!” I was puzzled（疑惑不解）. I thought , perhaps this is not an appropriate（适当的）topic. “Well, I’d better change the topic.” So I said to him. “Well, shall we talk about the Great Wall? By the way, have you ever been there?” “Certainly, everyone back home will laugh at me if I leave China without seeing it. It was magnificent.” He was deep in thought when I began to talk like a tourist guide. “The Great Wall is one of the wonders in the world. We are very proud of it.” Soon I was interrupted(打断) again by his words: “You don’t say!” I couldn’t help asking, “Why do you ask me not to talk about it?” “Well, I didn’t request yo u to do so,” he answered, greatly surprised. I said, “Didn’t you say‘you don’t say’？”Hearing this, the Englishman laughed to tears. He began to explain “ ‘You don’t say’ actually means ‘really!’ It is an expression of surprise. Perhaps you don’t pay atten tion to English idioms.” I realized I had made a fool of myself. Since then I have been more careful with idiomatic expressions. Remember: what the English teachers said is always right to us students.69．A year ago, I paid no attention to English idioms because______.A. English idioms were not importantB.I was not careful with English idiomsC.
