Last week I did something that scared me. I stood in front of nearly 200 financial planners and I talked to them about why financial blogs are a good thing. I’m a confident writer. I’ve been doing this long enough that I know my strength and my limitations. I’m less confident as a speaker. I don’t have time to pause to collect my thoughts. I’m not able to edit. I’m afraid of being trapped in a corner without being able to talk my way out. Basically, I’m scared to speak.
It would be easy to simply refuse the chances that come my way. When somebody asks me to
speak in front of a group, I could say “no”. When radio and television stations call for an interview, I could say “no”. But for the past two years, I’ve been following my own policy to say “yes” to new chances.
To say “yes” is to live in fear. My goal is to continually improve myself to become better than I am today. One way to do that is to do the things that scare me, to take them on as challenges, and to learn from them ― even if I fail.
In mid-November, a local station asked me to appear on live television. “I realize it’s short
notice,” the producer wrote, “but we’d love to have you on the show if you’re available tonight.” I
was frightened. I thought about recent taped television interviews that I had hated. I was afraid of
what might happen.
But I also thought about the things that had gone right. I thought of how my speaking skills had improved over the past year. And then I thought of the book I was reading, a book that I had
bought for $1.29 at the local store. The Magic of Thinking Big was a huge bestseller during the
1960s. Written by Dr. David Schwartz, a professor at Georgia State University, the book contains
dozens of practical tips on how to take risks to achieve big goals. Schwartz argues that nobody
will believe in you until you believe in yourself.
So when the television producer asked if I wanted to appear on his show, I thought big. “Sure,” I said. “I’ll do it.” I acted confidently, but on the inside I was frightened. What I needed was techniques to build up my confidence and to overcome my fear.
1. Why is the author afraid of speaking in public?
A. He is aware of his potential.
B. He has few chances to talk.
C. He is not able to edit what he says.
D. He likes writing better.
2. The underlined words “my own policy” in Paragraph 3 probably mean?.
A. self-improving through challenges
B. hesitating before chances
C. turning down the invitations
D. saying yes to fear
3. The author mentioned the book The Magic of Thinking Big mainly because ?.
A. it was inspiring
B. it was a bestseller
C. its author was famous
D. its price was attractive
4. What is the author’s purpose to write the passage?
A. To analyze his strength and weaknesses.
B. To give practical tips on speaking in public.
C. To persuade people to follow his example.
D. To share his experiences of overcoming fear. ?

一、阅读理解。
A
Nola is a 41-year-old northern white rhino(犀牛) that lives at the San Diego Zoo Safari Park in Escondido, California. She is one of only four remaining northern white rhinos in the world, and the only one in the western part of the earth. The other three live in Kenya(肯尼亚).
Rhinos have lived on earth for more than 40 million years, but they are now at the risk of dying out. Hunters illegally hunt rhinos for their horns(角), which are used for art, jewelry, and decorations. They sell the horns for thousands of dollars per pound, though it is not allowed by law. Rhino horns are also prized as a key part in traditional medicine, even though scientific tests have proven that the horns cannot cure illnesses. Experts say that every eight hours, one rhino will be hunted.
Scientists are trying to find ways to prevent rhinos from dying out. In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell samples(细胞样品) from more than 8,000 different animal species until now, including the northern white rhino. Scientists hope that by studying the rhino cells, they will gain greater understanding of the species, and will find ways to increase its number.
Jeanne Loring works with the Frozen Zoo. Loring’s research focuses on pluripotent stem cells, which are cells that can renew and become any cell type. Coloring's lab at TSRI is working together with scientist Oliver Ryder of the San Diego Zoo to use plenipotentiary stem cells to try to increase the number of the northern white rhino. Loring said the goal is to start producing new rhinos through this method over the next couple of years.
1. We know from Paragraph 1 that northern white rhinos __________.
A. can live a very long life
B. will die out within a few years
C. have become seriously endangered
D. mainly live in the western part of the earth
2. What can we learn about rhinos from Paragraph 2?
A. Their meat is of great value.
B. They haven`t attracted much attention.
C. Their horns have been used to save lives.
D. Human activity greatly reduced their number.
3. What was the Frozen Zoo started for?
A. Studying the rhino cells.
B. Collecting cell samples from plants.
C. Preventing rhinos from being hunted.
D. Studying animals to help them survive.
4. We learn that pluripotent stem cells __________.
A. can be easily stored
B. don’t exist in all animals
C. can reproduce in a new form
D. are dangerous to normal cells
B
