Bob ________ with us together since he came to our school.| A．have worked | B．has worked | C．worked | D．will work |

答案
| B |
解析
试题分析：考查时态。本题的关键在于since(自从)；该连词一直都是与现在完成时连用的，表示从过去的某个时间开始到现在，所发生的事情。句意：自从他来到我们学校到现在，Bob一直都很我们在一起学习。故B正确。
点评：时态题的考查关键是抓住句子的上下文含义和句中的时间状语。要根据时间状语来选择合适的时态，在平时的学习中要注意积累有关时态的用法和各种时态的特殊之处。如since， so far等经常与现在完成时连用。在条件状语从句中用一般现在时代替将来时等等。 |
