Up to now, they _______enough money for students who can’t afford to go to school.| A．are raising | B．have been raising | | C．have raised | D．had raised |

答案
| C |
解析
试题分析：考查时态。本题的关键词是句中的up to now，直到现在；该时间状语与现在完成时使用。句意:直到现在，他们已经凑集到了足够的钱来帮助那些无法上学的孩子。故C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。 |
