For those who are conditioned to think that learning only happens in a classroom, the world of self-learning can be a little daunting. How do we best take   1  of these new opportunities?

Your interest in the subject is the essential driver of success. You can’t learn what you do not want to learn. Emotion is an important part of the learning   2  . If you are even moderately interested in a subject, give yourself  a chance. The key is to get started. If you can create some pleasurable   3 , you may find that the subject grows on you.

Don’t expect to understand things, much less remember them, the first time you study them. Trust that things will get clearer   4  your brain comes to grips with new information. It is like a cross-word puzzle. As you start to put the pieces together, or string the words together, the full picture becomes clearer. The brain learns all the time, but    5   its own schedule. Learning does not take place according to a schedule laid down by a curriculum or teacher. Some things are easier to learn than others. Some things just take    6  to click in. Keep at it, and you will gradually find that things that seem difficult at first , will become easy with time.

Your brain is struggling to form patterns to    7   new input from your learning activities. Sometimes, no matter how long you focus on one subject, your brain is not going to pick it up. If you are stuck, move   8  . Then cover the same general information from a different source, a different book, or a podcast, or an online lecture or a video. Try to become a  grazing learner, roaming the countryside,     9  a feedlot learner, just standing there in one spot. The broader your base, the easier it is to learn. Just as the “rich get richer”, the more you know,     10  you can learn.

Take full advantage of the Internet, iTunes, and     11  mobile devices, not to mention good old-fashioned books and magazines. Learn during “dead time”. Listen in your car, on the train, or   12  jogging. Have your learning with you while waiting in the doctor’s office, or listen while checking out at the supermarket. Anytime is     13 time. Remember, you are learning through exposure, not by nailing things down. It is more like moisture accumulation in a    14  , rather than building a brick wall.

The more varied your learning content, and the more varied the ways in which you learn, the       15 the puzzle will become. Different learning activities suit different people, at different times of the day. Vary your activities in order to keep your interest level   16   . Even if listening and reading work best for you, treat yourself to the odd video lecture, or get-together with other learners. This will renew your batteries.

The “loneliness of the distance learner” is a thing of the   17 . Join a learning communityon the web, where members share their knowledge and experience. Search for the communities that suit your interests and learning style. You will find encouragement, advice and stimulus from fellow learners,        18   from tutors, teachers and coaches. In these communities, you can measure your progress against your own goals, or compare your experience     19   that of other learners. You can even teach and help others, which is a great way to learn.

Never has it been easier nor more exciting to be a learner. Let constant learning be a major part of your life-style. The   20       will be constant, personally, socially, and professionally.

影响荧光强度的外部因素有哪些？

阅读下面短文，完成下列各题。
我不喜欢一个苦孩求学的故事。家庭十分困难，父亲逝去，弟妹嗷嗷待哺，可他大学毕业后，还要坚持读研究生，母亲只有去卖血……我以为那是一个自私的学子。求学的路很漫长，一生一世的事业，何必太在意几年蹉跎况且这时间的分分秒秒都苦涩无比，需用母亲的鲜血灌溉!一个连母亲都无法挚爱的人，还能指望他会爱谁把自己的利益放在至高无上位置的人，怎能成为为人类献身的大师
我相信每一个赤诚忠厚的孩子，都曾在心底向父母许下“孝”的宏愿，相信来日方长，相信水到渠成，相信自己必有功成名就衣锦还乡的那一天，可以从容尽孝。可惜人们忘了，忘了时间的残酷，忘了人生的短暂，忘了世上有永远无法报答的恩情，忘了生命本身有不堪一击的脆弱。
父母走了，带着对我们深深的挂念。父母走了，遗留给我们永无偿还的心情。你就永远无以言孝。有一些事情，当我们年轻的时候，无法懂得。当我们懂得的时候，已不再年轻。世上有些东西可以弥补，有些东西永无弥补。
“孝”是稍纵即逝的眷恋，“孝”是无法重现的幸福。“孝”是一失足成千古恨的往事，“孝”是生命与生命交接处的链条，一旦断裂，永无连接。
赶快为你的父母尽一份孝心。也许是一处豪宅，也许是一片砖瓦。也许是大洋彼岸的一只鸿雁，也许是近在咫尺的一个口信。也许是一顶纯黑的博士帽，也许是作业簿上的一个红五分。也许是一桌山珍海味，也许是一只野果一朵小花。也许是花团锦簇的华衣，也许是一双洁净的旧鞋。也许是数以万计的金钱，也许只是含着体温的一枚硬币……在“孝”的天平上，它们等值。只是，天下的儿女们，一定要抓紧啊!趁你的父母还健在。

对全文的理解，正确的一项是______。

A．孝顺父母是中 * * 的传统美德，对父母的挚爱是人世间最珍贵的情感
B．把自己的利益放在至高无上位置的人，怎能成为为人类献身的大师
