【正确答案】
A
【答案解析】[解析] 他邀请我去那个晚会,我拒绝了因为我那晚必须要完成作业。句中turn down:拒绝。decline:拒绝,如:She declined their invitation.她婉拒了他们的邀请。send:发送,寄信,如:She sent me a Christmas card.她给我寄来一张圣诞贺卡。accept:接受,如:He has accepted our invitation.他已经接受了我们的邀请。receive:接收,如:I've just received a telegram.我刚收到一份电报。只有decline意思上和turn down最接近,还有同义词refuse和reject。
