2．Google and Toyta have worked together to create a new smart car．It can run on the road without a driver．It drives itself．The self-driving car hasn't been on sale to the public，so we don't know how much it costs．Another thing most people want to know is whether it will be safe enough to run on the road．

According to CNN，self-driving cars will also help to reduce the number of cars in big cities．"Self-driving cars would be able to send you to the workplace and then pick up another peson instead of stopping in a parking lot．"

12．Do you know Roma people？They were called Gypsies（吉普赛人）by Europeans because they thought they came from Egypt（a country in Africa）．About a thousand years ago，the Roma people left their homeland．They are known as nomads because for hundreds of years many of them have lived in large groups that travel from place to place．They have no real homeland．
Today，the Roma are now living all over the world．They have kept their language and many customs．For example，it's important for Roma to marry other Roma．It's also a custom for parents to choose the person their children will marry．Roma people get married when they are young，sometimes even as young as 14．
Romany is the language of the Roma people，which was written down only recently．Because the Roma are nomadic and have moved all over the world，their language has developed in many different ways．It is sometimes hard for Roma in one part of the world to understand Roma from another part．
Roma music is famous all over the world，because many Roma throughout history have been musicians．Their music has influenced many other kinds of music，like classical and jazz．
Roma don't usually assimilate（同化） into host countries．Over many centuries，governments have forbidden them to marry each other，travel or wear their traditional bright clothes．They have their gold taken away from them-treasures（财富） from their parents and grandparents．They have been taken as slaves（奴隶），and have been forced to change their names．
But today，the Roma are finding ways to live in peace with others while keeping the treasures of their culture．"There is a will within us to continue to live as a people，"says George Kaslov，whose family arrived in New York from Russia a hundred years ago．"All the other ethnic（种族） groups who came to America assimilate gradually with time going； they lose their customs and language．But not the Roma，We hold out．"

56．What does the underlined word"nomads"in the 1st paragraph mean？A
A．People who move from place to place．
B．People who come from Roma．
C．People who have their own homeland．
57．What's the main idea of the last paragraph？B
A．George Kaslov has a strong will to live on．
B．The Roma still keep their customs and language．
C．The Roma are finding ways to keep the gold of their own．
58．What can we infer（推断） about the Roma according to the passage？C
A．Most of the Roma live in very unusual houses．
B．Most Roma get married either when they are very young or very old．
C．Their culture is very different from other European cultures．
59．What is the main purpose of the passage？A
A．To tell readers about an interesting culture．
B．To tell us why the Roma need our help．
C．To show us how all people are similar．
60．What would be the best title for the passage？C
