London (CNN) There is no God -- that's the conclusion of the well-known physicist Stephen Hawking, whose final book is published on Tuesday. The book Brief Answers to the Big Questions, which was completed by his family after his death, presents answers to the questions that Hawking said he received most during his time on Earth.
Other bombshells(爆炸性事件)the British scientist left his readers with include the belief that alien life is out there, artificial intelligence could outsmart humans and time travel can't be impossible.
"There is no God. No one directs the universe," he writes in the book." For centuries, it was believed that disabled people like me were living under a curse by God," he adds. "I prefer to think that everything can be explained another way, by the laws of nature."
While Hawking spoke of his lack of belief in God during his life, several of his other answers are more surprising. "There are forms of intelligent life out there," he writes. "We need to be cautious about answering back until we have developed a bit further."
"Travel back in time can't be ruled out according to our present understanding," he says. He also predicts that "within the next hundred years we will be able to travel to anywhere in the Solar System."
In remarks prepared by Hawking and played at the launch of the book in London on Monday, the scientist also turned his attention to the world he was leaving behind. His greatest concern, his daughter said, "is how divided we've become," adding ,"He makes this comment about how we seem to have lost the ability to look outward, and we are increasingly looking inward to ourselves."
Hawking's final message to readers, though, is a hopeful one. Attempting to answer the question "How do we shape the future?", the scientist writes, "Remember to look up at the stars and not down at your feet."
1.Which question is NOT probably included in the book Brief Answers to the Big Questions,?
A. Is there alien life? B. Does anyone direct the universe?
C. Is time travel possible? D. Does the solar system exist?
2.Hawking mentioned his disability in his book to________.
A. show his confidence. B. support his disbelief in God.
C. tell readers about his hardship. D. complain of God
3.What was Hawking most concerned about?
A. Artificial intelligence will outsmart humans.
B. Human beings are not united.
C. Technology will destroy the world.
D. Allen life will come to the earth some day.
4.What did Hawking suggest human beings do?
A. Contact alien life. B. Respect artificial intelligence.
C. Develop the earth. D. Explore the universe.

It is not easy getting the attention of tourists away from the well-known white sandy beaches of Byron Bay. But in this relying Australian surf town, a solar (太阳能的)-powered train might just do a good job.
Opening to the public in December 2017 along a 1.9-mile-long stretch (一段) of track that sat abandoned for more than a decade, the Byron Bay Rail Company has breathed new life into a pair of disused railcars dating back to the 1940s. They’re now used to transport passengers between Byron Bay’s central business district and the North Beach area. After remaining in service as part of a regional passenger rail network until the early 1990s, the aging railcars were out of service and sat uncared for — almost destroyed by time and unpleasant Aussie climate — in a railyard for more than 20 years. You’d never know it by looking at these nearly 70-year-old workhorses today, though: they’ve been decorated, equipped, topped with custom-made photovoltaic panels (定制的光电池板) and rearranged to accommodate up to 100 seated beach goers.
It’s those train-top PV panels that truly set the Byron Bay Rail Company’s flagship train apart from other heritage rail restoration projects.
Drawing additional power from a 30-kilowatt solar array (阵列) located atop the train’s storage building, the train is said to be the first in the world to be completely powered by the sun. Solar energy caught by the 6.5-kilowatt train-top solar panels is stored directly in an onboard battery system that powers motors, lighting and the like. When stopped at its home platform, the train pushes into chargers for quick battery top-offs with electricity produced by the storage building’s rooftop solar array. The 77 kilowatt-hour battery can hold enough juice for 12 to 15 runs on a single charge. During long periods of cloudiness when the solar arrays don’t get enough sun, the train uses the main electric network supply using renewable energy sold by community-based service Enova Energy.
The Byron Bay Rail Company’s first-in-the-world fully solar-powered train is a good example of historic rail preservation with a 21st century development. Operating as a not-for-profit company, the Byron Bay Rail Company also expected the AU$4 million line to be a way to relieve traffic jam between downtown Byron Bay and the rapidly growing North Beach area. Really, there’s no bigger unpleasant thing than sitting in bad traffic for 40 minutes trying to get to the beach.
1.What makes the train really extraordinary?
A. That it looks the same as trains from the past.
B. That it is powered by train-top PV panels.
C. That it runs along specially designed tracks.
D. That it is a heritage rail restoration project.
2.Which of the following statement is TRUE?
A. A 30-kimowatt solar array is fixed on the top of the train.
B. The train runs at the speed of 77 kilometers per hour.
C. The storage building is more than a shelter for the train.
D. It takes a long time to charge the train each time.
3.From the last paragraph, we can infer that ________.
A. the Byron Bay Rail Company has made a big profit with the train
B. the Byron Bay Rail Company offers free rides with the train
C. the train plays a key role in the rapid growth of the North Beach area
D. it used to be very inconvenient for someone to drive to the beach
