1.Passengers are required to_____seated until the plane comes to a full stop. A.keep B.get C.remain D.leave 2.----Believe it or not,the man on the stage is over sixty. ----Really,but he doesn't look_______. A.this B.it C.that D.like 问题补充:答案为C B 1题之所以选remain 是因为后文"直到飞机停稳"表一直延续的状态=continue to be,stay in the same condition,是系动词.后加形容词作表语,一直站着坐着:remain standing/seated.如选keep ,seated前需加being; 2题中it指上文提到的 over sixty
