2171．Last Monday，I was asked to give the new students a test ________ their English level.（ ）
发布：2024/5/23 20:38:36组卷：4引用：5难度：0.72172．What if we had the power to control time，instead of moving from the past to the present to the future？What if we could jump and travel through time in a machine？What if we could go wherever and whenever we pleased？
The mysterious puzzle of time has kept people debating its nature for hundreds of years.Science fiction writers have turned it into imaginative stories.Some scientists have even attempted to explain it using math，trying to make the dream of time travel come true.
Albert Einstein said that time and space are one thing called "spacetime." He said there are three dimensions in space：height，width and depth.A scientist named Hermann Minkowski added time as a fourth dimension.
Einstein introduced two ideas that have led to theories about the possibility of time travel.The first is relativity.The idea of relativity is that the force of gravity causes space to bend，which causes time to twist.The second idea focuses on special relativity.The idea is that a traveler moving super-fast through flat spacetime will enter the future.Einstein considered time "relative" because it is measured based on where we are on Earth or in space.
Stephen Hawking believes that a time machine will never be built.If it were possible，he thinks we would already know.If a time machine could be built，how come no one from the future has invaded us？
The first science fiction story with this theme is The Clock That Went Backward by Edward P.Mitchell，which was published in 1881.Since then，thousands of books，films and television shows have explored the idea of time travel，in which some tools such as phones，watches，photographs and old books take travelers backward and forward.
