It is February 25, 2099, seven oclock. Time to get up and go to school，” said the clockrobot in a mental voice. Then the kitchenrobot gave him toast and eggs. Billy was amazed. While he was eating, the whole wall became a TV screen and Billy thought that it was great having robots to do everything for him. Billy ate his meal, watching a TV show. When he finished eating, the clothesrobot gave him his clothes very fast and dressed him. Then Billy went off to school. When Billy went outside, he saw a car with no driver waiting for him. The car said, “Hello, I will be driving you to school every day. Now would you please show your school ID card？” said the car. So Billy showed the car his school ID card and got in. The car began to talk to Billy about his school and his schoolwork. After that the car said, “I will check your homework today because you will have a very, very important lesson to learn in school today. Please put your homework on the blackboard.” Billy did so.The car checked Billys homework and then said, “Well done! You are a great student. All of your homework is correct.” When they got to school, Billy said to the car, “Goodbye. See you later.” The car said to Billy, “Good luck in your school.” Billy got into the classroom and took his seat at the front of the room. Then his teacher came in and said, “Welcome, children! Today we will have a hard but important lessonHow do robots help a human being？” 11Whats the best title of the passage?ABillys Daily LifeBHow Billy Go to School CHow Do Robots Help Humans in the FutureDRobots12Who cooked breakfast for Billy?AHis mother.

This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week.Leading researchers as well as science fiction writers will attend the event.It comes as NASA is preparing a multibilliondollar Mars research programme.“Turning Mars into a little earth has long been a topic in science fiction，”said Dr Michael Meyer, NASAs senior scientist for astrobiology (太空生物学)“Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal. But many experts are shocked by the idea.“We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet，” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK.Over the past months, scientists have become increasingly confident they will find Martian life forms.Europe and Americas robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.In addition, two different groups of scientistsannounced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气)The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planets soil. But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project.“Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native life forms, all the strange microbes that we hope to find buried in the soil，” said Dr Pratt.This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London.“We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said, “This is just wrong.”15The passage is about_.Aa plan turning Mars into a little earthBthe necessity of changing MarsCMars supporting lifeDfinding water in the Mars16Which of the following is NOT the reason why some scientists are against the plan?AThe project would wipe out all the native life forms on the Mars.BThe project will cost too much money and work.CWe would ruin Mars.DWe are destroying our own world at an unbelievable speed.17We can infer from the passage that_.Awater is a crucial factor for lifeBthe project will have little effect on the native life forms supposed to live on the MarsCMonica Grady is in favour of carrying out the little earth projectDthe idea turning Mars into a little earth is nothing but a science fiction18Which of the following supports the conclusion of microbes living in the Mars soil?AScientists found liquid water in the Mars.BScientists found signs of methane in the Martian atmosphere.CScientists found a lot of good soil on the Mars.DScientists found some creatures living on the Mars.完成句子阅读下列各小题，根据每句后的汉语提示，用句末括号内的英语单词完成句子。19_these, he spread some food on the table.(say)说完这些之后，他在桌上放了些食物。20_the journey, I was unsettled for the first few days.(worry)因为担心这次旅行，起初的几天我都心神不宁。21_in 1910, the museum is more than 100 years old.(build)这个博物馆修建于1910年，它已经有100多岁了。22Mrs White showed her students some old maps _.(borrow)怀特夫人给学生们展示了一些从图书馆借来的旧地图。23I am calling to enquire about the position _in yesterdays China Daily.
