下面的材料旨在丰富学生在是非问题写作方面的思想和语言，考生在复习时可以先分类阅读这些篇章，然后尝试写相关方面的作文题。
学习语言的人应该明白，表达能力和思想深度都靠日积月累，潜移默化。从某种意义上说，提高英语写作能力无捷径可走，你必须大段背诵英语文章才能逐渐形成语感和用英语进行表达的能力。这一关，没有任何人能代替你过。
因此，建议你下点苦功夫，把背单词的精神拿出来背诵文章。何况，并不是要求你背了之后永远牢记在心：你可以这个星期背，下个星期忘。这没有关系，相信你的大脑具有神奇的能力。背了工具箱里的文章后，你会惊讶的发现：I can think in English now！
1. Critical Thinking
Critical thinking is a path to intellectual adventure. Though there are dozens of possible approaches, the process can be boiled down to concrete steps. This article offers some starting points for your journey.
Be willing to say “I don’t know”
Some of the most profound thinkers of our time have practiced the art of critical thinking by using two magic phrases: I don’t know and I’m not sure yet.
Those are words many people do not like to hear. We live in times when people are criticized for changing their minds. Our society rewards quick answers and quotable “sound bites.” We’re under considerable pressure to utter the truth in 15 seconds or less.
In such a society, it is a courageous and unusual act to pause, to look, to examine, to be thoughtful, to consider many points of view—and to not know. When a society embraces half-truths in a blind rush for certainty, commitment to uncertainty can move us forward.
This willingness to give up certainty can be hardest to accept when it comes to notions that seem obvious. “Many things are certain,” some people say. “For example, it’s obvious that two plus two equals four.”
Think again. When we use the base-three number system, two plus two equals 11. A child learning to write numerals might insist that two and two makes 22. And a biologist might joke that two plus two adds up to a whole lot more than four when we’re talking about the reproductive life of rabbits.
Even scientific knowledge is not certain. At a moment’s notice, the world can deviate from what we call “laws” of nature. Those laws exist inside our heads—not in the world. What’s more, modern science tells us many things that contradict everyday certainties. For example, physics presents us with a world where solid objects are made of atoms spinning around in empty space, where matter and energy are two forms of the same thing. Even in mathematics and the “hard” sciences, the greatest advances take place when age-old beliefs are reexamined.
Define your terms
Imagining two people arguing about whether an employer should extend family health care benefits to people who live together but are unmarried. To one person, the word family means a mother, father, and children. The other person applies the word family to any long-term, supportive relationships between people who live together. Chances are, the debate will go nowhere until these people realize they’re defining the same word in different ways.
Much opinion conflict can be resolved—or at least clarified—when we define our key terms up front. This is especially true with abstract, emotion-laden terms such as freedom, peace, progress, or justices. Blood has been shed over the meaning of these words. It pays for us to define them with care.
Practice tolerance
Having opinions about issues is natural. When you stop having opinions, you’re probably not breathing anymore. The problem comes when we hold opinions in a way that leads to defensiveness put-down, or put-offs.
Going hand in hand with critical thinking is tolerance for attitudes that differ from yours. Consider that many of the ideas we currently accept—democracy, Christianity, voting rights for women, civil rights for people of color—were once considered the claims of “dangerous” and unpopular minorities. This historical perspective helps us accept a tenet of critical thinking: What seems outlandish today may become widely accepted a century, a decade, or even a year from now. 感谢您阅读《Ideas 》一文，留学群(liuxuequn.com)编辑部希望本文能帮助到您。
