D  D 解析: 1. 1.pile up (=lay in a pile or as if in a pile) 把......放成一堆, 堆积：pile up the books on the table (把书堆在桌子上) 。Pile up作不及物动词用, 意为“积压; (若干汽车) 相撞”：1) Perishable goods are piling up at the docks. (码头上易腐烂的货物堆积如山。) 2) Several cars piled up after ignoring the fog warning on the motorway. (由于无视高速公路上的大雾警告, 有好几辆汽车相撞。) 2.be charged with受指控犯有......; He was charged with murder. (他受指控犯有凶杀罪。) 3.I am sure that +从句。He is sure to come. = He is certain to come.但在it作形式主语, that引导主语从句时, 主句中表语只能用certain, 不能用sure.
