[单项选择]
Remember the days when companies such as Microsoft and Mc-Kinsey took immense satisfaction from subjecting job candidates to mind-crunching strategy sessions If you thought that was rough, imagine an interview in which no amount of research or questioning of insiders will help. Imagine instead that all you can do is have a healthy breakfast, pick out your nicest suit, and hope for the best. In the new interview, they’re not just testing what you know. They’re also testing who you are.
It’s called the situational interview, and it’s quickly becoming a must in the job-seeking world. In the post-Enron culture of caution, corporations are focusing on an obvious insight: that a gold-plated resume and winning personality are about as accurate in determining job performance as Wall Street analysts are in picking stocks. Now, with shareholder scrutiny, hiring slowdowns, and expense-reducing, no manager can afford to hire the wrong person. Hundreds of compa

[填空题]
An insect is not afraid of gravity, but it is in deadly fear of another force of nature. This force is called surface tension. A man coming out of a bath carries with him a film of water about one fiftieth of an inch in thickness. This weighs about a pound. A wet mouse has to carry its own weight in water. A wet fly has to lift many times its own weight, and as everyone knows, a fly once wetted by water or any other liquid is in a very serious position indeed. An insect going for a drink is in as great danger as a man leaning over the edge of a cliff in search of food. If it once falls into the grip of the surface tension of the water -- that is to say, gets wet -- it is likely to remain so until it drowns. A few insects contrive to be unwettable: The majority keep away from their drink by means of long proboscis.
What is the best title for this passage
( ) and Surface Tension.

[填空题]There is nothing illogical or synthetic about the humility ( modesty ) of great bookmen in calling attention to the limitations of the book.

It loses its charm and much of its value when accepted 4 No one would have been more 5 than Aristotle if he could have known of the excessive and 6 veneration that would be given to his ideas in centuries to 7 . When his works became the 8 words of advance knowledge, 9 knowledge became neither advanced nor vital.
The particular occasion for these remarks is that there are 10 here and there that some of us in the book world may be 11 ourselves too seriously.
