also含较庄重色彩,通常用于主要动词之前(但若主要动词为be,则放于其后)
e.g.I’ve met Jane and I’ve also met her mother.

13.other/the other/others/another
这几个相类似的词是学生容易弄混淆的,其实意思大相径庭.
other其它的(人或物)  后面经常跟可数名词复数形式;
the other(两者中的)另一个  后面不可能跟复数形式;
others其它的人或物(已经包括在内)  后面不能跟名词,本身就含有名词的含义;

拓展:up to you 由你决定
e.g.It’s up to you to decide when you should do it.

17.The Earth is a planet and it goes around the Sun. Eight other planets also go around the Sun.

此句中的另外八颗行星,加上地球,就是人们常说的九大行星:水星(Mercury),金星(Venus),地球(Earth),火星(Mars),木星(Jupiter),土星(Saturn),天王星(Uranus),海王星(Neptune),冥王星(Pluto).
注意other和also的用法.
18.With so many stars in the universe, are we alone, or is there life out there in space?
[译文]宇宙中有这么多的恒星,我们是孤独的吗?太空中还有其他生命吗?
with so many stars in the universe是介词短语,在句中作状语,表示伴随情况.

19.It’s hard to understand how large the universe is.
[译文]很难理解宇宙到底有多大.
It’s …to do sth. 表示做什么事情很怎么样.it是形式主语,真正的主语是后面的动词不定式.一般来说,当主语比较长,我们都选择用这种形式.
e.g.It’s difficult to study English well.
学好英语很难.
20.The astronauts have gone to the space station.
[译文]宇航员已经去了太空.
have gone to 表示已经去了,但是到了没有或者回来没有,都不知道;

她已经去了北京.(现在人不在这里)
She has been to Beijing.
她去过北京.(现在人可能在这里,可能在上海,也可能在南京)
四、语法点拨:现在完成时(Ⅱ)
1.现在完成时态的句子转换
(1)肯定式:They have / They’ve just finished their homework.
否定式:They haven’t finished their homework yet.
疑问式:Have they finished their homework yet?
简略答语:Yes, they have. / No, they haven’t.
(2)肯定式:She has seen the movie already.
否定式:She hasn’t seen the movie yet.
疑问式:Has she seen the movie yet?
简略答语: Yes, she has. / No, she hasn’t.
2.现在完成时态与一般过去时
一般过去时与现在完成时都可以表示在过去发生的动作.但现在完成时态强调的是过去发生的某一动作对现在造成的影响或结果,它重点说明现在的情况,是基于现在时间的时态,因此它不能与明确指出过去时间的状语如:yesterday, last week, last night, last month, … ago, just now等连用,但可以和一些不明确指出时间的时间状语如:already, yet, just, before等连用.一般过去时态只表示过去的某时间发生的动作或存在的状态,叙述过去的事实,不涉及现在的情况,甚至与现在无关.因此它可以和表示过去某时间的时间状语连用.
因此,凡是含有表示过去的时间状语的句子,都必须用一般过去时,不能用现在完成时.
e.g.Did you get up early?
你起来得早吗?(指动作本身)
Has he got up?
他起来了吗?(指现在的情况,即:还在不在床上?)
She has been ill for three days.
她已经病了三天了.(现在还病着)
She was ill for three days.
她病了三天.(她现在病好了)
