Problem: Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.

Problem: Article: US actress Natalie Portman,33, has always been praised for her smarts. At 18, she went to Harvard University following the release of her film Star Wars: Episode I in 1999. Four years later, she graduated with a bachelor's degree in psychology. Then she took graduate courses at Hebrew University in Jerusalem. She speaks six languages and has twice been published in scientific journals. You may think she has achieved all of these things easily thanks to her fame as actress, but only Portman herself knows what she has been through. In late May, the Oscar winner revealed that her time at Harvard had some "dark moments" when she gave a speech to graduating Harvard students. "I felt like ... that I wasn't smart enough to be in this company, and that every time I opened my mouth I would have to prove that I wasn't just a dumb actress," she said. It was that fear that helped her carve out her own path, Portman admitted "My belief that I could handle these things (her own limitations) ... was half the battle. The other half was very hard work," she said. "Sometimes, your insecurities and your inexperience may lead you to take on other people's expectations, standards, or values," she added.
Answer: She experienced a hard time.
Solution:
What can be inferred about Portman in Harvard from her speech?
