题目内容

2．Please lock the door；______，bring the umbrella to me．It looks as if it is going to rain．（　　）
A．as a resultB．in returnC．in additionD．as well

分析 请把门锁上；此外，带一把雨伞给我．天看起来要下雨了．

解答 答案：C．根据Please lock the door和bring the umbrella to me可知是让他做两件事，因此两句之间用in return表示"此外"，其他选项的含义分别是A"结果"；B"作为回报"；D"也"．所以答案是C．

点评 考查介词短语辨析．
in addition to和in addition都是很常见很常用的短语，都有"除了、还有"的意思，但它们的用法是完全不同的，In addition to整个词组相当于一个介词，所以to的后面要接宾语．例如：
In addition to native plants，this garden contains numerous trees and flowers from overseas．
除了当地的植物之外，这座花园还有无数来自海外的花草树木．
In addition相当于副词，通常放在从句的句首，后面接完整的句子．例如：
This garden has the best collection of native plants．In addition，it contains numerous trees and flowers from overseas．
这座花园有当地植物的最佳珍藏．另外，它还有无数来自海外的花草树木．

12．A dog's tail can tell you a lot more than you might think．Is it wagging（摇）to the left or is it wagging to the right？
"The direction of tail wagging does in fact matter，"said Giorgio Vallortigara，a professor at the University of Trento in Italy．Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind-whether you're a human or another dog．
What's the difference between a left wag and a   right wag？Professor Vallortigara and his colleagues have studied 43 dogs of various breeds-German Shepherds，Beagles，Boxers，Border Collies and some mutts．They find that if a dog wags its tail to the left，it's feeling anxious or nervous．The reason could be an unfamiliar or dangerous situation，an unfamiliar person，or an unfamiliar and possibly threatening dog．But if the tail is wagging to the right，it means the dog is feeling relaxed and approachable．
"The tail is a very important signal，"said Thomas Reimchen，a biologist at the University of Victoria in British Columbia，Canada．"There is a lot of visual information that dogs use when communicating with each other．"
How did the scientists figure all this information out？They had the dogs in their study watch videotapes of other dogs．When the dog on the tape wagged its tail to the right，they say the other dogs remained calm and cool．But when the dog on the tape wagged its tail to the left，the other dogs got anxious．
The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously．They suspect that it might be something the dog does without even thinking about it-kind of like when you get goose bumps if something scares or startles you．They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging．As Reimchen said，"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before．"
