Will there ever be another Einstein? This is the undercurrent(潛流) 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 ___________.
A.have to create new math B.create a unified theory
C.have to be born now D.push math to its limits
2.The underlined words “knotty” in the fourth paragraph means ____________.
A.easy B.interesting C.strange D.difficult
3.Which of the following will be useful for the next Einstein to be born?
A.There will be music around.
B.There will be no problems to solve.
C.There will be suitable philosophy to study.
D.There are only a few physicists.
4.The bold words “unified theory” in Paragraph 2 refers to ___________.

I woke up late and had breakfast in a hurry. I had never been late and didn’t want my boss to be unsatisfied.
However, it seemed that day wasn’t a lucky one for me from the very second I left my flat. The moment I wanted to rush downstairs one of my stiletto heels (細(xì)高跟) broke.

One day I heard that one of my dear friends had lost his mother. This made me sad, for my friend was very close to his mother. He had been by her side as she traveled through her long and hard journey with cancer. At this time, many memories about my loved ones that had passed away came flooding to me. Finally these memories passed, but it was really sad to think that my friend would have to go through the pain.
Three times I tried to write an email to my friend and three times words failed me. I am a person who is not often lost for words and I decided to have a sleep. Upon waking up I could hardly wait for my computer to work, the words I needed were there. I was still left with a heavy heart although I had sent an email.
Everything in this universe is balanced and indeed it is. Three days later, I received his reply letter. I was happy to hear that he’d been admitted to (錄取) Cambridge University. It served as a gentle reminder for me that my friend would be okay and that life would go on.
Everything in life is balanced; the lowest feelings change places with the highest feelings. Without the lows, we would never appreciate the highs. No matter how dark the clouds seem to be, the sunshine is always there and just waiting for the opportunity to shine through.
