[单选题] 年美国《福布斯》杂志推出全球“税负痛苦指数”榜单,把中国排在第二位,使中国公众关于税负问题的争论升温,近日人们重提这一排名,税负讨论再掀高潮。《福布斯》杂志推出的税负排行榜在其他国家内没有受到关注,在中国却产生了轰动效应,确实值得思考。有必要指出:税负分析得出什么结论是次要的,首先是分析态度。如果先是在脑海里框定了结论,再从材料中找依据、用适意的方法来论证,那么,结论肯定是偏颇的。这种分析模式就是不公平的范式。由此出发考察情况,可说《福布斯》的分析根本是不公平的。 这段文字针对的主要问题是( )。

[不定项选择题]共用题干 第二篇

Love or Hate?

We have saved as a final set of emotions to two most important emotions connected with other people:love and its opposite,hate.Love can be seen everywhere.Yet surprisingly,love has been the subject of less scientific research than other emotions,such as anger and fear. The reason for this may be two fold.Firstly,love is a very complex emotion,difficult to describe and measure. Secondly,unlike many radical emotions,radical love is generally not a problem. Thus less medical attention has been paid to it.
What is love?This is a complex question and requires a complex answer. Love is a strong,positive attraction and feeling for another person or thing. But it is more than this.It also involves feeling of caring,protection,excitement,and tenderness.When two people are in love,they feel drawn to one another;they greatly enjoy each other's company;and they may be sexually attracted to one another.
Sometimes it is easier to think in terms of different kinds of love:romantic love,brotherly love, and so forth.Though they are different in some respects,they share one important characteristic: a strong positive feeling toward another.
Our feelings toward other people are often complex.We may love someone and,at the same time,be angry with him.Or we may love someone,even though we are jealous of him.We mighi even love someone and,at the same time,hate for some precise reason.
Hate is a strong negative emotion toward someone,and is due to anger,jealousy,or some other factor. Like love,hate can be a very strong emotion.It can also be very dangerous.The question is often asked,"Is it bad to hate?"The best answer is probably" sometimes yes and sometimes no." Usually hate does not help us.It makes us feel unhappy and makes us do things that may hurt others.However,sometimes it may be necessary to hate and hurt someone in order to protect loved ones. Which characteristic is shared by different kinds of love?
A.A strong negative emotion toward someone.
B.A strong positive feeling toward another.
C.Unhappy feeling toward another.
D.Jealous feeling toward someone.

[简答题]
If I wanted to, I could come up with a dozen excuses. I was fired after a long day of work. Or maybe I was hungry. The simple truth is, when I walked into the living room and my 12-year-old son looked up at me and said. "I love you," I didn’t know what to say. For several long seconds all I could do was standing there and staring down at him, waiting for the other shoe to drop. He must need help with his homework was my first thought. Or he’s going to hit me up for an advance on his allowance. Or he’s assassinated his brother—I always knew it would happen someday—and he’s trying to prepare me gently for the news. Finally I asked, "What do you want " He laughed, and started to run from the room. But I called him back. "Hey, what was that all about " I demanded. " Nothing," he said, grinning, "My health teacher said we should, tell our parents that we love them and see what they say. It’s sort of an experiment. "
The next day I called his teacher to
