【文章內(nèi)容簡介】 . When I joined, I asked Mark to give me feedback every week so that anything that bothered him would be discussed quickly. Mark not only said yes but immediately added that he wanted it to be mutual. As the years went by, sharing honest reactions became part of our relationship. Getting feedback from your boss is one thing, but it39。s as important to get feedback from those who work for you. This is not an easy thing to do as employees are often eager to please those above them and don39。t want to criticize or question their higherups. A good leader recognizes that most employees won39。t feel fortable challenging authority, so it falls upon authority to ask for feedback. I firmly believe that. You lead best when you walk sidebyside with your colleagues. 28. What happened to the author after moving to Silicon Valley? A. She started to regret giving up her previous job. B.

Now it has been discovered that crows may understand analogies （類推法）.It was once thought that only humans could understand analogies, which help us to solve problems creatively，put things into categories and make scientific discoveries. To test this ability in animals, scientists do“relational matchingtosample”( RMTS ) tests according to the IFL Science website. If a pair was AA, for example,then picking BB to match it would be correct. 1f the pair was CD, however, then EF would be correct. Apes and monkeys have learned RMTS, but scientists wanted to know if crows could do it, too. An international team led by Edward Wasserman from the University of Iowa in the US first trained two hooded crows to match things by color, shape and number in what is called “identity matchingtosample (IMTS)”, then moved onto RMTS. For the IMTS test, the birds were put in a cage with a plastic tray that had three cards and two cups in it. The card in the middle was the sample card. The cups on either side were covered with the other two cards : One was the same as the sample ( in the color, shape, or number of shapes pictured), while the other wasn39。t. The cup with the card that matched the sample card contained two worms to eat. In the second part of the experiment, the birds were tested with relational matching pairs. A card with two samesized circles, for example, meant they should pick the test card with two samesized squares and not two differentsized circles. The birds did well in the more difficult test and picked the correct card more than three quarters of the time , Science News reports. Wasserman was surprised that crows were able to solve the problem without any training in RMTS.“What the crows have done is extraordinary,” he said in a news release. “Honestly, if it was only by force that the crows showed this learning, then it would have been an impressive result. But this was spontaneous.” So perhaps it39。s time to stop saying “bird brain”permanently ! can be inferred from the passage?A. Crows were the first animal to take the test.B. Scientists trained crows for both tests.C. Crows could get rewards in the first test.D. In RMTS, the crows picked more correct cards than in IMTS. to the RMTS test, if the birds were given the sample card with one square and one circle, which sample would be the correct result?A. Two samesized circles.B. One circle and one triangle.C. Two samesized squares.D. Two differentsized circles and triangles.34.
