Answer 1

1 C 这个是非谓语 因为是be related to 或 be connected with 所以用related to 或 connected with
翻译：警察盘问了所有和抢劫案有关的人

2 A 这个是固定用法 appear 在这里是系动词 It seems/appears to be或It seems/appears +that...这里是第二种 to只是对于的意思
翻译：对地球上的科学家来说 恒星好像在改变位置

3 B 第一个空也是非谓语
die out 灭绝 die away die down都是逐渐变弱的意思
第二个空应该是定语从句that which均可
翻译：动物灭绝有许多原因 但是人类所起的作用最重要（也就是人类最应该对动物灭绝负责）

Answer 4
