2011年3月11日在日本发生的大地震中，福岛核电站发生了核泄漏，其周边区域的空气中漂浮着放射性物质，其中含有碘的同位素131  53I，131  53I中的中子数为 A. 53      B. 78      C. 131     D. 184 答案：【答案】B 【解析】考查原子的组成及表示方法。在表示原子组成时元素符号的左下角表示质子数，左上角表示质量数。因为质子数和中子数之和是质量数，所以中子数是131－53＝78，答案选B。Making a good job choice is almost as good as choosing a good life. So, choosing a job is one of the most important decisions to make in life.For my job, there are three important things that I will consider:The first one—that I must work in an area I like—is most important to me. Someone once said if you find a job that you enjoy, then you won't have to work another day. I would like to work in an area where I can be more creative. I would like to be the most valuable member there. All this is possible only if I like what I do.The second one is that the area of my work must lead me to solve some new and hard problems. I would like to stay in the same area for a long time. In order for this to happen, the work must provide enough problems. More than just working to live, I enjoy making a difference and trying my best for the whole progress. I would also like to be well remunerated for my hard work, so I can lead a comfortable life with this hard-won money. Then I can provide the best for my family.The third important thing is that I would like to work in an area that would help other people. The work in my mind is in fields such as the army, training or management. In such areas, I can help to develop the abilities of others and bring out their best. It would be a most satisfying job to help young people to become the best that they can be. When I become old, I would like to look back with a great sense of satisfaction that thousands of people have become better persons through my work.I accept the idea that no one should make a choice of a job suddenly or quickly. He should decide what he wants to be in the long run. Then, he should decide how he works towards it. He should study the proper courses, read the books and speak to knowledgeable persons in that field before making a job choice. A good choice will most probably lead to a better life.【1】According to the passage, a good job choice probably makes people ________.A. solve fewer problemsB. choose a good lifeC. be good family members【2】The writer considers an enjoyable job most important because ________.A. he has to bring out his bestB. it can make him more creativeC. he will have to work another day【3】The underlined word "remunerated" in the means"________.A. trained B. praised C. paid【4】The writer wants to tell us that everyone should ________.A. become a knowledgeable personB. join the army to become a better personC. make preparations to find a satisfying job【5】What is the best title for the passage?A.
