教授是个极其有名的音乐大师，在授课的第一天，他给自己的新学生一份乐谱。“试试看吧！”他说。乐谱的难度颇高，学生弹得生涩僵滞、错误百出。“还不成熟，回去好好练习！”教授在下课时，如此叮嘱学生。
学生又练习了一个星期，第二周上课时正准备让教授验收，没想到教授又给一份难度更高的乐谱：“试试看吧！”上星期的课教授也没提。学生再次挣扎于更高难度的技巧挑战。第三周，更难的乐谱又出现了。
这样的情形持续着，学生每次在课堂上都被一份新的乐谱所困扰，然后把它带回去练习，接着再回到课堂上，重新面临两倍难度的乐谱，却怎么样都追不上进度，一点也没有因为上周练习而有驾轻就熟的感觉，学生感到越来越不安、沮丧和气馁。
教授走进练习室。学生再也忍不住了，他必须向钢琴大师提出这三个月来何以不断折磨自己的质疑。教授没开口，他抽出最早的那份乐谱，交给了学生。“弹奏吧！”他以坚定的目光望着学生。不可思议的事情发生了，连学生自己都惊讶万分，他居然可以将这首曲子弹奏得如此美妙，如此精湛！教授又让学生试了第二堂课的乐谱，学生依然呈现出超高水准的表现……演奏结束后，学生怔怔地望着老师，说不出话来。
“如果，我任由你表现最擅长的部分，可能你还在练习最早的那份乐谱，就不会有现在这样的程度……”钢琴大师缓缓地说。

Goals can help you do, be and experience everything you want in life. Instead of just letting life happen to you, goals allow you to make your life happen. Successful and happy people have an idea of how their life should be and they set lots of goals to help them succeed. By setting goals you are taking control of your life. It' s like having a map to show you where you want to go. Think of it this way. There are two drivers. One has a destination in mind which is laid out for her on a map. She can drive straight there without any wasted time or wrong turns. The other driver has no goal or destination or map. She starts off at the same time from the same place as the first driver, but she drives without an aim around, never getting anywhere, just using up gas and oil. Which driver do you want to be？ Winners in life set goals and follow through on them. Winners decide what they want in life and then get there by making plans and setting goals. Unsuccessful people just let life happen by accident. Goals aren't difficult to set―and they aren't difficult to reach. It's up to you to find out what your goals and ideals （理想) really are. Research tells us that when we write a goal down, we are more likely to achieve. Written goals can be reviewed regularly, and have more power. Like a contract with yourself, they are harder to neglect （忽视) or forget. Also when you write your goals in a particular way, you are able to make yourself be continuously alert （警觉) to situations that will further your goals.
The writer gave the example of two drivers to show _____.[ ]
A. how stupid the first driver was B. the importance of having a map and right direction C. how stupid the second driver was D. the importance of setting goals
According to the passage,successful people are different from unsuccessful ones because _____.[ ]
A. the successful people set goals for everything and can get help from others B. the unsuccessful people always set unrealistic plans for themselves C. the successful people set goals in their lives and make plans to carry it out D. the unsuccessful people make plans for everything but can not work hard
Which of the following is TRUE according to the passage？[ ]
A. Goals can make you gain everything you want in life. B. Only successful people can be happy. C. If you want to succeed,you need toset long-term goals instead of short-term Goals. D. When we put our goal down on papers,we are more likely to succeed.
Which is the best title for the passage？[ ]
A. Goals help you succeed B. How to succeed C. Why we always fail D. A research on setting goals

In a book called Magnificent Obsession, by Lloyd C. Douglas, a description is given of people helping others but doing it secretly. When difficult problems worried an individual, friends nearby would meet to discuss possible solutions without the individual knowing their actions. When a solution was agreed upon, one or two of the friends would carry out the plan and solve the problem secretly, to the great delight of the worried individual. The helpers would stand by privately, content with their success. No reward was given to the problem solvers, not even a sincere "thank you", because they were never known. This concept is popular today but in a different way. The phrase "pay it forward" is now used when one person helps another. However, the person helped may not be able to repay the person or group that helped them. So rather than return the favor to their helpers, they are supposed to help someone else in the future, which means they pay it forward. It is a sense of responsibility which makes us want to give back in equal measure to the one who has helped us. But, in this case, the responsibility turns to helping someone in the future. Suppose your elderly grandmother pays part of your schooling. She may tell you there is no need to repay her because it is a gift from someone who loves you very much. Nothing would please her more than to have you use her money to get a good education. You may never be able to repay her for such a gift. However, she not only gave you some money, but she provided you with an example that you should also help other people who need it. People with serious needs are everywhere. Many are children who need better clothes, more books and even better schools. Some are elderly people who can't afford their medicine or a doctor's care. Consider how you can "pay it forward" rather than pay money back to your grandmother.

A. they hadn't solved the problems thoroughly B. they had solved the problems secretly C. they were friends of the worried individual D. they expected to be paid back in the future
The underlined word "pay it forward" means _____.[ ]
A. to repay someone who has helped you B. to pay someone else who needs help C. to help someone who has helped you D. to help someone else who needs help

用燕麦幼苗所做实验，下列说法正确的是①组实验：将切下的胚芽鞘尖端C水平放置，分别取两个琼脂块A、B紧贴在C切面上，数小时后如图中的甲所示处理②组实验：在左侧光照射下，将附有琼脂X和Y的胚芽鞘顶端放在旋转器上匀速旋转，数小时后如下图中的乙所示处理
[ ]
A．两天后，胚芽鞘D向右（B侧)生长，是因为琼脂块B生长素多，向下运输使右侧（B侧)生长受到抑制B．两天后，胚芽鞘E向左（B侧)生长，是因为琼脂块B生长素多，向下运输使右侧（B侧)生长受到促进C．两天后，胚芽鞘G向左（X侧)生长，是因为琼脂块Y生长素多，向下运输使右侧（Y侧)生长快D．两天后，胚芽鞘G直立生长，是因为琼脂块X和Y生长素浓度相同
