It is hard to predict how science is going to turn out , and if it is really good science, it is impossible to predict. If the things to be found are actually new, they must be unknown in advance You cannot make choices on this matter. You either have science or you don't and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits. The only solid piece of scientific truth about which I feel totally confident is that we don't know enough about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, a clear piece of news. It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange seems the way ahead . In earlier times, they either pretended to understand how things worked or simply made up stones to give answers. Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered. Because of this, we are sorry. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted. But we are making a beginning, and there ought to he some satisfaction. There are probably no questions we can think up that can't he answered, sooner or later. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, arid pay attention. Which of he following is NOT mentioned about scientists in earlier times? A) They falsely declared to know all about nature. B) They did not believe in results from scientific observation. C) They paid little attention to the problems they didn't understand. D) They invented false rules to explain things they didn't understand.

When I was 23 years old I was in a dangerous relationship with the man who was my fiance at the time. I was being physically and verbally abused on a daily basis. I was financially tied to him after he spent all my savings to pay his debts but I wanted to be free! For the longest time I was too embarrassed to tell my mother about the situation. She had warned me about him. But, eventually, I worked up the courage to tell her and she sent me the money I needed to leave. Before the money arrived, he found out what I planned to do. I was so scared of what he might do that I decided to leave without taking all my belongings and just get out of there. Then, on my way to safety, my car died! I had automobile insurance (thanks to my mom) so I called the AAA and had them pull the car to a garage. It turned out the repair was going to cost $800 and the money my mom sent hadn't arrived by that point. The owner of the garage must have known something was up because he asked what was wrong. I told him a brief version of my story and promised him I could pay him in two days. He never told me his name but I will never forget him or what he did for me that day! He fixed the car immediately and told me he would not accept any payment ---- ever! He said he had a daughter almost my age and hoped that if she ever needed help in the future then some stranger might do the same for her. Since then I have tried to help people in my own way. Now I have a beautiful 12-year-old daughter and I hope throughout her life she can help others and be helped when she needs it, like I was! Which of the following words can be used to describe the owner of the garage? A) Confident. B) Modest. C) Helpful. D) Clever.

Q: In this fast-shifting world, there can be no guarantees attached to any particular job. But there is much that you can do to protect yourself from the change of society, by equipping yourself with the skills to manage your career more effectively. You need to be a career activist. If you lost your main source of income tomorrow, could you find a different source to replace it? The most important thing in protecting yourself now and in the future is ensuring that you have choices. Don't let yourself be held back by a lack of skill development, or fear of change. Some people have been good performers in their own organization but discovered that they are stuck. Because they are so closely related to a particular company or industry, their skills are not readily transferred to other jobs. Don't put all your eggs in one basket. If you limit yourself to one particular area or sector, you limit your opportunity, too. In a global market place, many jobs come and go quickly as changes in the stock market. Today's hottest job may not exist tomorrow. If you love computers, then this work represents a great choice. But don't enter a field just because you think that's where the hot jobs are; even if the job is available, it may not match well with your own skills and abilities. Start with entry of your own strengths and interests, then see where you may match up best in the job market. Some people are afraid of change because _ . A) they have got a hot job B) they have no other better choices C) they have got used to a certain job D) they have no other skills and interests
