Article: When I decided to write the story of my early years growing up in poverty,many of my friends and family members were shocked.They were more interested in my story of success,such as how I was able to create the nation's largest law firm and sell it to a bank,and how one sells a law firm for millions of dollars.That's the story everyone wanted me to write,but it's not the story I wanted to tell. Looking back,I see so clearly how often,throughout my boyhood,I was touched by random acts of kindness that helped shape me into the man I am today.And random acts of violence and ignorance played just a powerful role in making me who I am.Becoming a successful lawyer involves hard work,but escaping generational poverty is the hardest thing I have ever done. I chose to write the story of my childhood years in poverty,with the hope that a child somewhere in the world will read my story and be inspired to break the cycle of poverty.My publisher was quick to point out that the market would be small for a memoir written by a ly unknown author.To everyone's surprise,the book received over 1,000 prepublication orders one month before the scheduled launch date.The book launch scheduled for October 1,was moved up to September 14.Less than four months later,the first print run of 5,000 copies were sold out. Today,the memoir is being used by universities,high schools and middle schools,as a case study of the behavior patterns of the culture of poverty as well as valuable lessons on how to succeed in life.Here is a quote from the principal of a middle school in Texas on October 27,who is using my memoir for students 5th through 8th grades:"We are halfway through your story.It is changing the lives of our students and the perspectives of our teachers." Question: By mentioning the principal of a middle school,the author proves _ . Options: A: how valuable his book is B: what students are really interested in.

Read the article and select the best answer. Article: Bad teeth can be painful and even be deadly. Infections of the gums and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed. Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water. When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel , the hard surface on teeth, to help prevent holes from forming.

Ques:Read the article and select the best answer. Article: As a senior, my future is always on my mind. To be exact, thoughts of the future have kept me up countless nights and made me worry enough to do poorly on more than one test. Because of this, words of wisdom are a source of comfort. Steve Jobs gave a speech to Stanford's graduating class in 2005 and his words resound repeatedly in my mind whenever I think about my future. It wasn't always like that, though. It started when I became a junior, when college came into view. It's the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He, too, felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well. This doesn't mean that students shouldn't attend college, but rather that they shouldn't worry so much. You'll get where you need to go, even if your path is a bit more winding than you'd like. Jobs talked about the hardships in his work. His love of his work helped him carry on and he got where he was meant to be, which restates the point: don't panic. One particular part of his speech stayed with me. Steve Jobs quoted the saying "Stay hungry, stay foolish" and it has become my motto. Staying foolish is realizing that you are still a fool, no matter how much you've learned or experienced. There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated. Steve Jobs's level of success is attainable, and I aim to prove that. With the will power to go into the world living every day like it's my last and allowing the future to take care of itself, I will do great things. In the last moments of my life, I'll be proud of what I have done and hope to have all the wisdom a person could wish for. Question: What did the author gain from Jobs's speech? Options: A: Courage to drop out of school. B: Confidence in defeating Jobs. C: Interest in computer industry. D: Bravery to face uncertainties.
