These sites include “MySpace”, used mainly by teenagers and young adults. MySpace is an online community that lets people share messages and pictures with an increasing number of friends. It is the most popular social networking site on the Web. YouTube is another Internet site that became more popular this year. This Web site lets anyone create, share and watch short videos. People can watch almost anything on YouTube: news, sports and entertainment events. There are music videos, and videos made by people in their own homes. These include videos of people singing or dancing, or animals doing funny things. Three young men created YouTube almost two years ago as a personal video sharing service. They recently sold it to Google for more than one and one half billion dollars. Games and entertainment also became a larger part of the Internet this year. One Internet social site is called Second Life. It is an online world in which computer users create a new self and live a different life.

Once I decided to climb a mountain and asked my uncle for advice. He said, “Unfortunately, I am so busy these days. But if no one leads, you are likely to be lost. ” I said, “What am I afraid of? If lost, I will call you for help. ” He said with a smile, “Well, I hope you will not get lost. Good luck. ” I confidently said, “I think I’ll certainly be able to return safely.” I finally set off by myself. Everything was very smooth at first. When I came close to the top, a sudden strong wind burst. I had to find a shelter to hide my sleeping bag inside. An hour later, I crawled（爬）out and looked around. All the places were so familiar and those roads appeared to extend（延伸）in all directions. What should I do? I decided to call for help, but except the sleeping bag, there was nothing left. Going on in my despair（绝望）, suddenly I found a map from the sleeping bag. Could that be put by Uncle? Anyway, I followed the directions on the map and succeeded in finding a smooth way home. Stepping into the house, I was pleased to see Uncle again and said excitedly, “Today, thanks to your map, or I really could not return home. My baggage, including my mobile phone, was blown away. ” Strangely Uncle asked, “The map?” I said, “The one you put in my sleeping bag.” Seeing the map, Uncle suddenly laughed again, “This is your 4-year-old cousin Linda’s painting of a Super Spider-Man.” I was surprised, “However, I really got this ‘map’ to find it down the road.” Uncle said, “You can come down the mountain successfully, not due to the map,

河北省武邑中学2018-2019学年高一英语上学期寒假作业17 阅读理解第一节:阅读理解阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题卡上将该选项涂黑。 A “ Fire! Fire!” What terrible words to hear when one wakes up in a strange house in the middle of the night! It was a large, old, wooden house and my room was on the top floor. I jumped out of bed, opened the door and stepped outside the house. There was full of thick smoke. I began to run, but as I was still only half-awake, instead of going towards the stairs I went in the opposite direction. The smoke grew thicker and I could see fire all around. The floor became hot under my bare（赤裸的）feet. I found an open door and ran into a room to get to the window. But before I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle（包袱）of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me. I saw a doorway in fire, then I put the bundle over my face and ran. My feet burned me terrible, but I got through. As I reached the cold air outside, my bundle of clothes gave a thin cry, I nearly dropped it in my surprise. Then I was in a crowd gathered in the street. A woman in a night-dress and a borrowed man’s coat screamed as she saw me and came running madly. She was the Mayor’s wife, and I had saved her baby. 1. When the fire arose in the middle of the night, the author was _______. A. at home B. sleeping C. sitting in bed D. playing games 2.The author saved the baby _____. A. because he was very brave. B. because he liked the baby very much. C. because he just happened to save it. D. because it was t he Mayor’s baby. 3. He ran in the wrong direction because he _______.

I will give you some advice next day," I told the boy. —I told the boy that some advice . 4."I saw the movie three days ago," she told the teacher. —She told the teacher that she had seen the movie . 5.He said, " I am living with my parents." —He said that he . 6.She said, " My brother also wants to go there." —She said that her brother also there. 7.The boy said, "I brought the book home vdth me." —The boy said that he the book home with him. 8."I don’t like this hat," the girl said. —The girl said that she didn't like hat. 9."I have finished my homework," he said. —He said that he his homework. 10.He said, "These books are mine"
2019-2020学年浙江省宁波市镇海中学高一上学期期中数学 试题 一、单选题 1．设全集U =R ，集合{ } 2 20A x x x =-<，{} 1B x x =>，则()C U A B =() A ．{} 12x x << B ．{} 12x x ≤< C ．{} 01x x << D ．{} 011x <≤ 【答案】D 【解析】先解一元二次不等式,化简集合A,再利用数轴进行集合的补集和交集运算可得. 【详解】 解一元二次不等式化简集合A,得{|02}A x x =<<, 由{|1}B x x => 得{|1}U C B x x =≤, 所以(){|01}U A C B x x ?=<≤. 故选D. 【点睛】 本题考查了一元二次不等式的解法,集合的交集和补集运算,用数轴运算补集和交集时,注意空心点和实心点的问题,属基础题. 2．函数f(x)=23x x +的零点所在的一个区间是 A ．（-2，-1） B ．（-1,0） C ．（0,1） D ．（1,2） 【答案】B 【解析】试题分析：因为函数f(x)=2x +3x 在其定义域内是递增的，那么根据f(-1)= 15 3022 -=-<,f （0）=1+0=1>0,那么函数的零点存在性定理可知，函数的零点的区间为（-1,0），选B 。 【考点】本试题主要考查了函数零点的问题的运用。 点评：解决该试题的关键是利用零点存在性定理，根据区间端点值的乘积小于零，得到函数的零点的区间。 3．下列四组函数中，表示同一函数的是（ ） A ．()f x =与()g x = B ．()f x = ()g x =
C ．2()lg f x x =与()2lg g x x = D ．0()f x x =与01()g x x = 【答案】D 【解析】在A 选项中，前者的y 属于非负数，后者的0y ≤，两个函数的值域不同；在 B 选项中，前者的定义域为1x >，后者为1x >或1x <-，定义域不同；在 C 选项中， 两函数定义域不相同；在D 选项中，()0 f x x =定义域是{}()01 |0,x x g x x ≠= 的定义域为{}|0,x x ≠，定义域不相同，值域、对应法则都相同，所以是同一函数，故选D. 4．已知5log 2a =，0.5log 0.2b =，0.20.5c =，则,,a b c 的大小关系为（ ） A ．a c b << B ．a b c << C ．b c a << D ．c a b << 【答案】A 【解析】利用10,,12 等中间值区分各个数值的大小。 【详解】 551log 2log 2 a =<< ， 0.50.5log 0.2log 0.252b =>=， 10.200.50.50.5<<，故 1 12 c <<， 所以a c b <<。 故选A 。 【点睛】 本题考查大小比较问题，关键选择中间量和函数的单调性进行比较。 5．关于函数()21 45 f x x x = ++的说法，正确的是() A ．()f x 最小值为1 B ．()f x 的图象不具备对称性 C ．()f x 在[]2,-+∞上单调递增 D ．对x ?∈R ，()1f x ≤ 【答案】D 【解析】将函数()f x 变形为2 1 ()(2)1 f x x =++,根据2(2)0x +≥可知函数()f x 的最大值为1,所以A 不正确;D 正确;
