下图展现的是1848年1月29日，法国政府勒令恩格斯在3个小时内离开巴黎，在3天内离开法国的情景。马克思、恩格斯在革命生涯中，多次被反动政府驱逐，这种现象说明当时

①马克思、恩格斯的革命活动已产生了较大影响
②马克思、恩格斯是公认的革命领袖
③欧洲的政治空气较为反动
④社会主义运动的发展引起了反动政府的恐慌

课文《我的第一本书》中，为什么说我的第一本书“值得用崇敬的心灵去赞美”？

已知函数f(x)对任意$x\in R$都有$f\left(x+4\right)-f\left(x\right)=2f\left(2\right)$，若$y=f\left(x-1\right)$的图象关于直线x=1对称，且f(1)=2，则f(2011)=(    )

    Last Friday, I agreed to meet some friends at 6：00 p．m．in a coffee shop．The weather was sunny, so I decided to walk there．I arrived ten minutes early．I ordered a cup of coffee and sat watching people．There were some boys playing football on the street，and a small boy was running after the ball as it rolled (滚)across the road．

    Suddenly(突然)，there came a car．It was going very fast．When the driver saw the boy in his way, he braked(刹车)hard．But it was too late…The small boy was lying on the street without moving．To everyone's surprise，the car didn't stop．It drove away quickly．

    People ran to the boy．There was a cut on the boy's head and he lost a lot of blood．The coffee shop owner (主人)telephoned the police．Soon an ambulance (救护车)arrived and took the boy to the hospital．

    At 6：30 p．m., the police arrived and started questioning people．About half an hour later, they asked me to go to the police station because I saw everything．I gave them all the information I knew because I really wanted them to catch the driver．I didn't leave the police station until 8：00 p. m．After that I went home because I didn’t feel like talking to anyone．

    The next day, the boy's parents called me to say thanks．They also told me their boy was fine and the driver was in the police station now．
