- 请教两题选择题,谢谢1.Galileofoundthatheav
- 1. Galileo found that heavy objects and light
objects _____ at the same eed.
A. fell B.fall
(本题选A.我曾经听说客观真理用一般现在时的,
但本题用了过去时,为什么? 谢谢)
2. When you _____ the furniture, tell me, please.
A. finished moving
B. have finished moving
帮我
- 1/选B.fall /你说的对,客观事实和真理都用一般现在时.
给你在词典上找了个例子:
Galileo demonstrated that objects of different weights fall at the same speed.
伽利略证实不同重量的物体落下的速度相同。
2/选B. have finished moving
这个句子的结构:please tell me When you _____ the furniture.
是祈始句, 请告诉我一声,当你搬完家具的时候.
祈始句用以表达命令，要求，请求，劝告等。都是现在时,分句用现在完成时与主句一致.
不能用过去时,过去时表示与现在没关系了.
