17．What do you think would happen if the engine _______ suddenly stop working？（　　）

A．

would

B．

might

C．

should

D．

could

分析如果发动机万一突然停止工作，你认为会发生什么？

解答答案C．本句是if 引导的虚拟语气，根据前面主句中的动词形式是"would+动词原形"，可知表示的是与现在或将来事实相反的情况，故从句中动词的形式应该用"动词过去式、should+动词原形或者were to do sth"三种情况的一种情况．根据从句中的动词和选项的设置来看，可知本题是表示与将来事实相反的虚拟语气，故选C项．should在本题中的意思是"万一"．

点评本题考查虚拟语气．if引导的虚拟条件句是高考考试的重要考察点．应对虚拟语气题目时，我们需要记住一个公式：语法+语境=正确答案．语法就是指上述各种虚拟语气的结构和用法，需要考生牢牢把握这些虚拟语气的基础知识；语境即说话人的语意、情感、态度等．实际上，目前高考中的大多数语法单项填空题都不是纯粹的考查语法结构，必须把语法或惯用法与语境结合起来才能得出正确答案．因此我们应遵循这个解题模式．

7．For professional athletes，it's all about training，speed，strength，and endurance．It's no different for the homing pigeon （传信鸽）-the flying athletes，but they're not going for the gold with every race．They just want to go home．
When you walk into Mike Beavers'pigeon loft （鸽棚） you'll hear the happy coo （咕咕叫） from his flock of homing pigeons．Beavers raises and races these birds near Kingsley，Iowa，USA．
"Most people don't believe me，"says Beavers．"They ask，‘How do you do that？'Then once you start explaining it，it really kind of catches their interest and they say，‘Wow，that's pretty awesome．'"
His love for the birds took off when he was a kid and he's spent the past 30years building his team of racing pigeons．It's a family hobby．"I got out of it for a few years and after I got married，my daughter came along and it was something that she and I could do together because I don't shop，"says Beavers．
Beavers has about 150birds，but these aren't ordinary pigeons．They're born to race，conditioned to travel long distances，and they have the instinct （本能） to always return home no matter where they are．
"They come back because this is home，"says Beavers．"This is where they were born and raised and it's just their instinct to go home．Nobody even really knows the reason．It's one of nature's secrets and nobody has found it yet．"
These pigeons are kind of like a flying GPS．That's what makes them so special．If you take a wild pigeon you find under a bridge and take it out 100miles away，it is just going to find the closest bridge and that's going to be its new home．It is the instinct that is bred into these birds over centuries and centuries．

8．Directions：Read the following passage．Answer the questions according to the
information given in the passage．
Kids and Ponds
Years ago there was a group of kids who would hang around at some local ponds in the woods near their houses in Warwick，Rhode Island．In summer they caught frogs and fish．When winter arrived they couldn't wait to go skating．Time passed，and the ponds became the only open space for the kids to enjoy themselves in that neighborhood．
One day．a thirteen-year-old boy from this group of kids read in the local newspaper that a developer wanted to fill in the ponds and build over a hundred small houses called condominiums．So the boy went door to door and gathered more than two hundred signatures （签名）to stop the development A group of citizens met and decided to support him．
At the meeting of the town planning board （委员会），the boy was quite nervous at first and spoke very softly．But when he saw the faces of his friends and neighbors in the crowd and thought about what was happening to their favorite ponds，his voice grew louder．He told the town officials that they should speak for the citizens．He also insisted that they should leave enough space for children．A few days later，the developer stopped his plan．
Nine years later，when that teen was a senior in college，he was informed that the developer was back with his proposal to build condominiums．Now twenty-two years old，he was studying wetlands ecology．He again appeared before the town planning board．This time as an expert witness，he used environmental protection laws to explain restrictions on development in and around wetlands and the knowledge of wetlands ecology to help improve the development．Finally some condominiums were built，but less than half the number the developer wanted．The ponds where those kids used to hang around were protected by a strip of natural land，and are still there today．
