1.B
have sb do sth:order or arrange (that sb does sth) 命令或安排（某人做某事）:I`ll have the gardener plant some trees.我要让园丁种些树.* Have the driver bring the car round at 4.让司机4点钟把汽车开来.
2.A
get sb to do sth:cause,persuade,etc (sb/sth) to do sth 使,说服...（某人[某事物]）做某事:[I couldn't get the car to start (ie make it start) this morning.今早我无法把汽车发动起来.* He got (ie persuaded) his sister to help him with his homework.他说服他姐姐帮他做家庭作业.* You'll never get him to understand.谁也无法让他明白.* I can't get her to talk at all.我简直无法叫她说话.]
get 也可以用于get sb done:[ She got her fingers caught in the door.她的手指让门给夹了.]这时更倾向于一种已经完成的状态.鉴于本句的的具体语境,不做此种用法考虑
同时也可以get sb doing sth:[bring (sb/sth) to the point at which he/it is doing sth 使（某人[某事物]）做某事:Can you really get that old car going again?你真能让那辆旧汽车再跑起来?* It's not hard to get him talking; the problem is stopping him!让他说话不难,难的是说开了止不住他!] 无此选项,故选择A
