Koshiba had a legendary life. When he was a kid, he dreamed of being a soldier or musician, but his dream was broken when his right hand was damaged by polio(小儿麻痹症).While in the hospital, he read Adlbert Einstein’s books and     1     (become) interested in physics. He never made it to the top of his physics class in high school, but went on to study at the University of Tokyo, then the University of Rochester,     2    he earned his PhD. “There are things in the world you can achieve despite poor academic records.” Koshiba said. What     3     (count) most is adopting an active attitude toward studying.

Zoos play an important role in the world for conservation and education. They are     4     (particular) important for endangered species. Many animals are critically    5     danger and may go extinct in the wild, but in zoos, they are going wrong. Many others are already extinct in the wild and only animals     6     are kept in zoos survive. Even those critics of zoos often recognize that it is better to have species preserved somewhere than lose them altogether, as animals held in zoos     7     (protect) from serious threat.

    8     (wear) different colors can affect how you feel and how others react to you, so it is important to consider this when deciding     9     to wear in the morning. If you want people to take you seriously, put on navy blue or black. Blue would also be helpful for an interview or oral examination because it relaxes you and makes you feel calm. Red gets you noticed by everyone and make you feel energetic,     10    be careful, as it can raise your heart rate and not everyone want this effect. So think carefully before you leave your house.

Tu Youyou is the first Chinese female scientist who was awarded a Nobel Prize.

She studied medicine and     11     a deep knowledge about traditional practices, which enabled her to be chosen to establish a team to find a cure for malaria in 1969. With the idea that Chinese herbs might hold the secret, Tu Youyou and her team studied some related literature and     12     a lot of researches with limited resources. They used modern research methods to study these Chinese herbs one by one.

After hundreds of failed experiments, they eventually came across a     13     chemical. Tu Youyou bravely volunteered to be the first human subject in the test on humans. The chemical they     14     artemisinin, has now become the world’s most effective drug for fighting malaria.

As one of the most     15     figures of science in the 20th Century, she is not interested in fame and she continues to do research today     16     her age. What she did not only saved millions of lives, but also bridged the Eastern and Western worlds.

“I was attacked by a tiger shark in October 1997. It was near my home on the island of Kanai. The waves were really good, so nothing was stopping us.”   That was until large shark came right up under Mike and _______ his teeth into Mike’s lower leg. There’d been no splashing, no noise, and Mike felt no pain, only intense pressure on his _______ body.

As he tried to get himself free, the shark bit down harder, shaking its head back and forth and tossing Mike around like a doll. Mike hit the shark hard in the face, again and again until the shark _______ him. As Mike swam back into shore, he felt his lower right leg spamming(痉挛); when he looked down, he realized it was _______. The shark had bit his lower leg off. Mike’s friends came to his aid immediately, and tried to control severe bleeding and rushed him to the hospital.

When Mike opened his eyes, he realized he was in the hospital.

During the next few weeks, Mike researched prosthetics (假肢) and considered the _______.

As soon as Mike was given the OK by his doctors, he did what many of us might consider _______: he started riding the waves again. In fact, his first time back was near the site of his attack. But Mike was unshaken. Instead, he was curious-why was he attacked? Mike _______ that the water had a fishy smell the morning of the attack. Was that what attracted the shark?

His curiosity led him to research sharks, and while he never_______ why he became a target, Mike did learn something that would change his life: Humans are far more _______ to sharks than the other way around, Mike tells Reader’s Digest. “I watched a documentary called Sharkwater, and I learned about the ________for shark fin soup and the fact that 70 million sharks a year are killed for their fins alone.”

His unique situation as a shark survivor empowered him to give sharks a ________, Mike says. He began working with the Hawaii state legislature (立法机关)to help pass a ________ on shark-related products.” I partnered with other like-minded shark attack survivors and marine biologists, and we headed to Washington to urge the government to create a nationwide bill protecting sharks.”
