21、Science is always advancing over time. A self-driving car from the Google may be coming to a street near you. However, you won’t be able to buy it now. “We’re working to build the world’s most experienced driver,” Kraft, director of the project, said. “Everything that we learn in one of our cars gets passed to all of our cars. But you may need to get over the idea of traditional car ownership along the way.”
Google’s software has already driven 5 million miles in U.S. cities, including an “early rider” test in Phoenix last April. Since then Google has grown confident enough to remove the “auxiliary wheel”: a human “safety driver”. Powering the vehicle’s self-driving functions is a series of cameras, radars and sensors on the car’s roof, which detect everything nearby from other vehicles and passers-by to cyclists.
Kraft stressed that Google’s cars aren’t connected—they don’t need a 5G wireless link to go anywhere. “The car has everything it needs to drive on the car itself.” He said, “There are no signals coming from outer space or something telling it to turn right.” The resulting ride may not be too exciting but safe. Kraft added. “We can see three football fields down the road, we would come to a stop before we ran into these crowds.”
Google’s system has a major advantage over the semi-autonomous（半自主的）systems of Tesla and Cadillac, both of which need continued human attention. Kraft said Google plans to have service in every major city by 2028 with thousands of cars driving themselves.
【1】What does the underlined words “auxiliary wheels” in Paragraph 2 refer to?
A. A car that is very old.
B. A driver who has been trained well.
C. A part of a car used to sound the alarm.
D. A condition where a driver doesn’t know his role.
【2】Why is Google’s car thought to be safe in the text?
A. Because it can get away from danger easily.
B. Because it is equipped with 5G wireless link.
C. Because it can stop before the crowds occasionally.
D. Because it can keep a safe distance from everything nearby.
【3】What can we learn from the text?
A. Google’s software has not been tested.
B. Google’s cars have not been put into the market.
C. Driving the Google’s car may not be too exciting.
D. Google’s cars still need driver’s attention all the way.
【4】What does the author think of the Google’s car?
A. It’s affordable.
B. It’s still a theory.
C. It has a bright future.
D. It’s the most advanced by now.
22、 The Milky Way is full of habitable (宜居) places, with roughly half of all sunlike stars hosting Earth-size worlds that could be friendly to life.
Here’s a good sign for alien hunters: More than 300 million worlds with similar conditions to Earth are spread throughout the Milky Way galaxy. A new analysis concludes that roughly half of the galaxy’s sunlike stars host rocky worlds in habitable zones where liquid water could pool or flow over the planets’ surfaces.
Astronomers estimated the number of these planets using data from NASA’s planet-hunting Kepler spacecraft. For nine years, Kepler stared at the stars and watched for the brief twinkles produced when orbiting planets block a portion of their star’s light. By the end of its mission in 2018, Kepler had spotted some 2,800 exoplanets (外星行星) — many of them nothing like the worlds orbiting our sun.
But Kepler’s primary goal was always to determine how common planets like Earth are. The calculation required help from the European Space Agency’s Gaia spacecraft, which monitors stars across the galaxy. With Gaia’s observations in hand, scientists were finally able to determine that the Milky Way is populated by hundreds of millions of Earth-size planets orbiting sunlike stars — and that the nearest one is probably within 20 light-years of the solar system.
It took more than half a century for scientists to start pinning down how many planets could possibly host life. In 1961, astronomers knew of no worlds orbiting stars other than the sun — and although planetary formation theories suggested exoplanets should be common, we had no observational evidence that they existed. But over the past decade, it’s become clear that planets are extremely common, outnumbering stars in the Milky Way. On average, nearly every star is home to at least one orbiting world.
Early estimates suggested that perhaps 20 percent of sunlike stars hosted a world that met those criteria. We now know that the number is closer to 50 percent, if not more.
Of course, many factors determine whether a world in the habitable zone is truly friendly for life. Planetary characteristics such as magnetic fields, atmospheres, and plate tectonics all play a role, and those are difficult to observe on small, faraway worlds.
【1】When the author says, “Here’s a good sign for alien hunters”, he probably means____.
A.that’s good news for hunters
B.we will find aliens soon
C.there is a clear signal from alien
D.many sunlike stars have been found that may be habitable
【2】How did Kepler work to find exoplanets?
A.By observing the brief flicker that occurs when orbiting planets block some of the star’s light.
B.By using the data from the European Space Agency’s Gaia spacecraft.
C.By calculating the stars in the galaxy.
D.Through its own calculation.
【3】What can we infer from paragraph 4?
A.Kepler’s primary goal was to make sure that the Earth is a common planet.
B.Kepler helped Gaia to calculate the planets.
C.Gaia is only 20 light-years away from the solar system.
D.Kepler monitors stars across the Milky Way.
【4】What does paragraph 5 mainly talk about?
A.The importance of planetary formation theories.
B.Exoplanets are common.
C.Scientists spent more than half a century to find out how many planets host life.
D.Astronomers have known of no worlds orbiting stars other than the sun since 1961.
【5】Many factors determine whether a world in the habitable zone is truly friendly for life EXCEPT____.
A.oxygen B.atmospheres C.magnetic fields D.plate tectonics
23、I have always been interested in making things. When I was a child, I enjoyed drawing, but I also liked making things out of clay (粘土). I won a prize for one of my paintings when I was fourteen. That may be why I went to art school four years later. But I studied painting at first, not pottery (制陶). I like being a potter because I like to work with my hands and feel the clay. I'm happy working by myself and being near my home. I don't like mass-produced (集体生产) things, because they are made by machines. I think crafts (手工艺) are very important and crafts-people make things cleverly with hands. They make our lives colorful. When I left school, I got some money. I hope to become a full-time crafts-woman. This work-place is small, but I wish to move to a larger one next year.
【1】From the passage we are sure that the writer is a _______.
A．student
B．teacher

24、 This year some twenty-three hundred teenagers (young people aged from 13-19) from all over the world will spend about ten months in US homes. They will attend US schools, meet US teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.
Here is a two-way student exchange(交流/交换) in action. Fred, nineteen, spent last year in Germany with George's family. In turn, George's son Mike spent a year in Fred's home in America.
Fred, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. The school was completely different from what he had expected—much harder. Students rose respectfully (尊敬地) when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The father's words were the law, and all activities were around the family rather than the individual. Fred found the food too simple at first. Also, he missed having a car.
“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”
At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize(批评) American schools," he says. "It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”
【1】This year _______ teenagers will take part in the exchange program between America and other countries.
A.twenty-three hundred B.thirteen hundred
C.over three thousand D.less than two thousand
【2】The whole exchange program is mainly to _______.
A.help teenagers in other countries know the real America

D.students go outside to enjoy themselves in a car
【4】After experiencing the American school life, Mike thought _______.
A.a better education should include something good from both America and Germany
B.German schools trained students to be better citizens
C.American schools were not as good as German schools
D.the easy life in the American school was more helpful to students
