去帮助那些需要帮助的盲人。故B正确。

4【答案】A

【试题解析】推理题。根据最后一段前2行For just US $38,you can help one person see; for $380 you can bring sight to 10 people; $1,300 helps teach a doctor new skills; and for $13,000 you can provide a training programme for a group of doctors who can make thousands of blind people see again.作者在呼吁我们为这个项目捐款，因为捐款可以帮助很多看不见的盲人重新看见光明。故A正确。

【分析】本句中含有一个非限制性定语从句who continue tens of thousands of blind people every year。其中的关系代词who指代先行词，在句中做主语。
