Module 3 Journey to space
Unit 3
Language in use
I’ve just made a model spaceship.
Has it arrived yet
Astronauts have already been to the moon.
We have not found life on any other planets yet.
现在完成时：某人曾经做过某事
某人已经做了某事
★ just, already, yet 可用于现在完成时,加以强调或说明。
★ just用来表示“刚刚”，already用来表示“已经”，
两者都用于肯定句中，一般置于have /has之后，already 也可
放在句末。在否定句及疑问句中用yet, 表示“还未”。
现在完成时表示该事件是在现在之前
的某一个时间里发生的，
重点在于强调这一动作对
现在的影响
一般过去时只表示过去的某一具体时
间发生的事情
I have just been to London. I went there last month.
我刚去过伦敦，是上个月去的。
I have already finished my homework. I finished it an hour ago.
我已经写完作业了，一个小时之前完成的。
A: Where have you put my book I can’t find it.
B: I put it on your desk yesterday.
当 A 问对方把自己的书放在何处时，他在意的是书目前在哪儿，故用现在完成时。
B的回答着重的是当时的动作，故用一般过去时。
有明确过去时间状语时，用一般过去时。
无明确过去时间状语时，判断使用现在完成时还是一般过去时的标准是：
看该行为是否对现在有影响，即该句强调或在意什么，着重点就在那里。

Do you know the relationship between
the days of the week and the space
Around the world
Many European languages use the names of the heavenly bodies for the days of the week.
Saturday is named after the planet Saturn (土星).
Sunday is the day of the Sun.
Monday gets its name from the moon.
在古代巴比伦，人类把太阳、月亮、火星、水星、木星、金星、土星等七个天体分配给星期中的七天：太阳——星期日，月亮——星期一，火星——星期二，水星——星期三，木星——星期四，金星——星期五，土星——星期六。由此，知道某一天的代表星，就知道是哪一天。至今，法语、意大利语、西班牙语、英语、德语中均有保留，日语则全部保留下来。
