Will there ever be another Einstein? This is the undercurrent（潜流） of conversation at Einstein memorial meetings throughout the year. A new Einstein will appear, scientists say. But it may take a long time. After all, more than 200 years separated Einstein from Isaac Newton.

Many physicists say the next Einstein hasn't been born yet, or is a baby now. That's because the search for a unified theory that would explain all the forces of nature has pushed current mathematics to its limits. New math must be created after the problem can be solved.

But researchers say there are many other factors working against another Einstein appearing anytime soon. For one thing, physics is a much different field today. In Einstein's day, there were a few thousand physicists worldwide, and the theorists who could argue with Einstein probably would fit into a streetcar with seats to spare. Education is different, too. One key aspect of Einstein's training that-is little noticed is the years of philosophy he read as a teenager --- Kant, Schopenhauer and Spinoza, among others. It taught him how to think independently about space and time and it wasn't long before he became a philosopher himself.

And Einstein was a clever musician. The interplay between music and math is well-known. Einstein would play his violin hard as a way to think through a knotty physics problem.

Today, universities have produced millions of physicists. There aren't many jobs in science for them, so they go to Wall Street and Silicon Valley to apply their analytical skills. Those who stay in science don’t work alone and they sometimes do experiment together which takes years.

It's hard to imagine a renegade(背叛者) like Einstein standing it. “Maybe there is an Einstein out there today,” said Columbia University physicist Brian Greene, “but it would be a lot harder for him to be heard.”

1.According to the second paragraph, the next Einstein will ___________.

2. The underlined words “knotty” in the fourth paragraph means ____________.

3. Which of the following will be useful for the next Einstein to be born?

4.The bold words “unified theory” in Paragraph 2 refers to ___________.

Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that couldn’t be solved the night before can often appear more manageable, although the evidence（证据）until now has been personal experience. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight（洞察力）and problem-solving.
“If you have some newly-got memories in your brain, sleep acts on these memories and rebuild them, so that after sleep the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist（神经病学专家）at the university. To test the theory, they taught volunteers two simple rules to help them turn some numbers into a new order．There was also a third，hidden rule，which could help them increase their speed in solving the problem．The researchers divided the volunteers into two groups：half were allowed to sleep after the training while the rest were forced to stay awake．Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group．“Sleep helped，”Born said in a telephone interview．“The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep，so it can act on the problem．”But Born admitted that he and his team don’t know how rebuilding of memories occurs or what governs it．Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can help develop creative thinking．Although the role of sleep in human creativity will still be a mystery，the research gives people good reason to fully respect their periods of sleep，they added．
60．The underlined phrase“sleep on it”in Paragraph 1 probably means_________．
A．to delay deciding something until the next day
B．to get as much sleep as possible
C．to go on sleeping without being disturbed

A．comparison    B．interview        C．survey          D．imagination
