The teacher told each child in the class to bring along a plastic bag containing a few potatoes. Each potato would be given a name of a person that the child hated, so the number of potatoes that a child would put in his/her plastic bag would depend on the number of people he/she could not forgive (宽恕).So when the day came, every child brought some potatoes with the name of the people he/she hated. Some had 2 potatoes; some 3, while some had up to 5 potatoes.The teacher then told the children to carry the potatoes with them wherever they went (even to the toilet) for one week.With days passing by, the children started to complain because of the unpleasant smell let out by the rotten (腐烂) potatoes they were carrying.Those children who had 5 potatoes really began to feel the weight of the heavier bags. After one week, the children were happy to hear that the teacher had finally ended the game. The teacher asked: "How did you feel while carrying the potatoes with you for one week?" The children started complaining of the trouble in carrying the heavy and smelly potatoes wherever they went.Then the teacher told them the hidden meaning behind the game. The teacher said: "This is exactly the situation when you carry your hatred (仇恨) for somebody inside your heart. The burden (负担) of hatred will pollute your heart and you will end up carrying an unnecessary burden with you wherever you go. If you cannot tolerate the smell of rotten potatoes for just one week, can you imagine what a burden it would be to have the hatred in your heart for your lifetime?"36.

Rotten potatoes are really a heavy burden.BOn the fourth Thursday in November, Americans celebrate the festival of thanksgiving. This festival is a time when the family comes together for a meal and gives thanks to the God for the blessings they have received. The first Thanksgiving festival was celebrated by the early ancient settlers who gave thanks to God for their good harvest.In America, Thanksgiving is a family holiday. It is on that holiday that all the family makes a special effort to get together. The feast is always held on Thursday and most people have a four-day holiday from school and work. Thus they are able to travel a great distance to be with their family.The Thanksgiving meal is traditionally turkey, which was the food for the first Thanksgiving. The table is filled with fruits, walnuts (胡桃) and many kinds of vegetables. For desert the main choice is usually pumpkin pie. The meal is a time for the members of the family to talk to each other. There will be talking before the meal, during the meal and long after the meal.On Thanksgiving morning there are sporting events and parades in many cities to mark the day. The family dinner is usually held in the afternoon around 4 o'clock. The mother will prepare the meal and the father will carve the turkey. He will preside at (主持) the head of the table. The meal will begin with a short prayer of thanksgiving to God for the blessings the family received. The father will also thank the family for coming together on this day. During the meal there is plenty of food for everyone present. The meal is a very joyful time. When it is over, some will help with the dishes and others will return to the living room to talk or watch television.In many ways the festival of thanksgiving is similar to the Chinese festival of Mid-autumn Day. For instance, it is a time for the family to get together for dinner.40. On Thanksgiving Day the family comes together ________.A. to watch sports events.B. to have a rest and talk with the family.C.

She has wanted to become an official Special Olympics volunteer ever since he started joining in the program in 2005.Calista decides that since she is only 7 and too young to be an official volunteer right now, she would try to help out in another way.

Inside were two other men, who, at Sikes’ command, produced food anddrink for him and the boy. Then Sikes told Oliver to get some sleep as they would be going out again.At half past one the men got up and checked their equipment, gathering several sticks as well. Sikes and the man called Toby left the house together, with Oliver walking between them. There was now a thick fog as they hurried through the deserted streets of the nearby town. Out in the country again, they walked down several small roads until finally they stopped at a house surrounded by a high wall. As quick as lightning, Toby climbed up and pulled Oliver after him. Inside the garden, they crept towards the house, and now, for the first time, Oliver realized in terror what purpose of the expedition was.Bill Sikes broke open a small window at the back of the house, and then shone his light into Oliver’s face.“Now listen. I’ m going to put you through here. Go straight through into the hall and on to the front door, and let us in. And if you don’t, you can be sure I’ ll shoot you. ”Oliver, stupid with terror, was lifted through the window into the house. Desperately, he decided to try to run upstairs and warn the family. He began to creep forwards.Suddenly, there was a loud noise from the hall.“Come back! ” shouted Sikes. “ Back! Back! ”Oliver stood still, frozen with fear. A light appeared, then two men on the stairs. Then a sudden bright flash, and a loud bang. Oliver staggered back. Sikes seized the boy’s collar through the window and pulled him back out into the garden.“They’ ve hit him! ” shouted Sikes. “He’s bleeding. ”A bell rang loudly, above the noise of more gunshots and the shouts of men. Oliver felt himself being carried across rough ground, and then he saw and heard no more.51. When was the story happening?A. On a rainy morning.B. On a sunny afternoon.C. On dark eveningD. On a foggy midnight52. The underlined word “crept” in the second paragraph probably means ______.A. came mercifullyB. walked gentlyC. mourned desperatelyD. ran hurriedly53. Which of the following was probably not taken with Sikes and his partner?A. A lightB. A gunC. A stickD. A hammer54. From the passage we can infer that______.A.Oliver together with Sikes and Toby was trying to conduct a murderB.Oliver was cut bleeding badly by a man with a sharp knifeC.Oliver was a kind, innocent boy despite joining in the activityD.Oliver didn’t know the purpose of the expedition until he was shot deadBAll of us have read thrilling stories in which the hero had only a limited and specified time to live. Sometimes it was as long as a year; sometimes as short as twenty-four hours, but always we were interested in discovering just how the doomed man chose to spend his last days or his last hours.Such stories set up thinking, wondering what we should do under similar circumstances. What happiness should we find in reviewing the past, what regrets?Sometimes, I have thought it would be an excellent rule to live each day as if we should dietomorrow. Such an attitude would emphasize sharply the values of life. We should live each day with a gentleness, a vigor, and a keenness of appreciation which are often lost when time stretches before us in the constant repetition of more days and months and years to come.Most of us take life for granted. We know that one day we must die, but usually we picture that day as far in the future, when we are in pleasant health, death is all but unimaginable. We seldom think of it. The days stretch out in an endless prospect. So we go about our little task, hardly aware of our listless attitude towards life.The same attitude, I am afraid, falls on the use of our abilities and senses. Only the deaf appreciate hearing, only the blind realize the various blessings that lie in sight. Particularly does this observation apply to those who have lost sight and hearing in adult life. But those who have never suffered loss of sight or hearing seldom make the fullest use of these blessed abilities. Their eyes and ears take in all sights and sound hazily, without concentration, and with little appreciation. Seldom do people realize how good it is being in good health until they have fallen ill .It is the same old story of not being grateful without missing.55.when reading the thrilling stories ,we usually .A.have curiosity about the hero`s limited lifeB.show great interest in our own livesC.find many regrets in reviewing the pastD.have mercy on the doomed men56.From the passage, we can learn that .A.the author thinks it would be excellent to live if he should die the next dayB.the disabled are anxious to regain their abilities and sensesC.each of us should treasure what we have possessed todayD.many of us are able to make full use of our time57.The underlined word “hazily”in the last paragraph probably means .A.happilyB.unclearlyC.freelyD.enthusiastically58.The best title for this passage may probably be .A.Not being grateful without MissingB. Giving a hand to the DisabledC. Making Use of Abilities and SensesD. Learning from Thrilling StoriesCIf you haven’t heard or seen anything about Road Rage in the last few months, you’ve probably been avoiding the media. There have been countless stories about this new and scary phenomenon, considered a type of aggressive driving. Y ou have most likely encountered aggressive driving or Road Rage recently if you drive at all。

(2)p 是q 的充分不必要条件, 则p 对应集合是q 对应集合的真子集; (3)p 是q 的充分必要条件,则p 对应集合与q 对应集合相等;(4)p 是q 的既不充分又不必要条件, q 对的集合与p 对应集合互不包含.3.B解析:B 【分析】通过举反例,判断出P 成立推不出Q 成立,通过判断逆否命题的真假,判断出原命题的真假得到后者成立能推出前者成立,由充分条件、必要条件的定义得到结论. 【详解】当0x =,3y =时,Q 不成立,即P Q ⇒不成立,即充分性不成立; 判断必要性时,写出原命题:3x y +≠时,则1x ≠或2y ≠, 由于原命题不好判断,故转化为逆否命题进行判断,即原命题变为:若1x =且2y =,则有3x y +=,对于该命题,明显成立,所以,原命题也成立;即必要性成立;所以P 是Q 的必要而不充分条件,故选:B 【点睛】关键点睛:判断一个命题是另一个命题的什么条件,一般先判断前者成立是否能推出后者成立,再判断后者成立能否推出前者成立;本题难点在于:利用逆否命题的真假性判断原命题的真假性,属于中档题.4.B解析:B 【分析】由()2200022110x x x -+=-+≥,可判断A ;由对数函数的定义域和对数函数的单调性得充分性不一定成立,必要性成立,可判断B ;运用作差法,判断其差的符号可判断C ;根据全称命题的否定是特称命题可判断D. 【详解】由()2200022110x x x -+=-+≥,得A 为真命题;由“b a <”不能推出“log 1a b <”,所以充分性不一定成立,由“log 1a b <”得“b a <”,所以必要性成立,故B 不正确;由0a b <<,则110b aa b ab --=>,∴11a b>,故C 正确;
