[不定项选择题]Up until a few decades ago, our visions of the future were largely—though by no means uniformly — glowingly positive. Science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all. 　　Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change. You might even be tempted to assume that humanity has little future to look forward to. 　　But such gloominess is misplaced.The fossil record shows that many species have endured for millions of years — so why shouldn’t we? Take a broader look at our species’ place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years. Look up Homo sapiens in the “Red List” of threatened species of the International Union for the Conservation of Nature (IUCN) and you will read: “Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline.” 　　So what does our deep future hold? A growing number of researchers and organisations are now thinking seriously about that question. For example, the Long Now Foundation has as its flagship project a mechanical clock that is designed to still be marking time thousands of years hence. 　　Perhaps willfully, it may be easier to think about such lengthy timescales than about the more immediate future. The potential evolution of today’s technology, and its social consequences, is dazzlingly complicated, and it’s perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. That’s one reason why we have launched Arc, a new publication dedicated to the near future. 　　But take a longer view and there is a surprising amount that we can say with considerable assurance. A.s so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves. 　　This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad.To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come. Which of the following would be the best title for the text?
A.Uncertainty about Our Future
B.Evolution of the Human Species
C.The Ever-bright Prospects of Mankind

[单选题]Years ago our cities were full of cars,buses and trucks．Now the streets are completely congested(拥挤的)and it is very difficult to drive a car along them．Drivers must stop at hundreds of traffic lights．What are our cities going to be like in ten or twenty years?Will enormous(巨大的)motorways be built across them?With-big motorways cutting across them,full of noisy,dirty cars and lorries,our cities are going to be awful places．How can we solve the problem? There are some good ideas to reduce the use of private cars．In 1989,for example,the authorities in Rome began an interesting experiment:passengers on the city buses did not have to pay for their tickets. In Stockholm there was another experiment:people paid very little for a season ticket to travel on any bus,trolley bus,train or tram in all the city. In many cities now some streets are closed to vehicles,and pedestrians are safe there. In London there is another experiment:part of the street is for buses only,so the buses can travel fast．There are no cars or taxies in front of them. In many cities pedestrians are now much safer because__.
A.no traffic is allowed on some streets
B.traffic is computer-controlled
C.cars move very slowly
D.only one way streets are open to traffic

[单选题]Very few of our birds stay with us the year round.Some come to us in the winter from the cold?north.Others come from the south to spend the summer with us.How do they know the way?Suppose?you were told to find your way to a place hundreds of miles away,do you think you could do it? Yet birds travel over mountains,forests,lakes and even across the oceans,and do not stray from?the path.They find their way back in the spring to the same orchard（果园）and the very trees where?they nested the summer before. It is wonderful how quickly birds travel such long distances from their summer homes to their?winter ones.Some birds have been known to fly hundreds of miles in a day.But others travel much?more slowly. Why do birds undertake these long journeys twice a year?Perhaps cold weather and lack of?food drive them from us in the autumn,but we cannot tell why they leave the sunny south to come?back to us in the spring.We know only that many of them like to make their nests and rear their?young in the north. We are sorry to see them go,but we know that when winter is over they will come back to us. Why do birds undertake those long journeys twice a year?
A.It is because of cold weather in winter.
B.It is because of lack of food in autumn.
C.It is because of the hot weather in summer.
D.There's some reason that is still not known clearly.
