现在完成时(2)
一、概述
考点介绍：just，already与yet的区别
二、一般过去时与现在完成时的区别
1. 一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调的是过去的动作。如：
I visited West Lake in 2012. 我在2012年游览过西湖。(强调过去参观西湖这一事实)
2. 现在完成时表示过去发生的动作对现在造成的影响或结果，强调的是过去的事情对现在的影响。如：
I have visited West Lake, so I won’t go this time. 我游览过西湖，所以这次我不去了。(强调对现在造成的影响)
注意：当没有明确的过去时间状语时，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，即该句强调什么。
三、just, already与yet的区别just意为“刚刚”，already意为“已经”，两者都用于肯定句中，一般置于have / has之后；否定句中则用yet, 表示“还(未)”，一般位于句末。如：
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。
He hasn’t finished his homework yet. 他还没有完成他的作业。

二、读写综合
A. 回答问题请阅读下面这篇文章，根据所提供的信息，回答5个问题。要求所写答案语法正确、语义完整，并把答案写在横线上。
Taikonauts have already visited the Moon and lived in space stations. They’ve never been to another planet, but they might visit Mars soon. Taikonauts will spend about six months getting to the planet, then about two years on the planet and about six months travelling back to the earth. They’ll be away from the earth for about three years, so they’ll need much food.
It’s very expensive to take food into space. It costs about 120,000 dollars to carry something that weighs one kilo, so an apple on Mars could cost 20,000 dollars! Of course, they will need to take much food with them to feed themselves for three years. This amount of food can’t stay fresh and is very expensive to take, so scientists need to help find food that is not very heavy.
At the moment,taikonauts in space stations eat dried food. It’s very light, so it doesn’t cost much money to carry it into space. But taikonauts stay healthier and happier if they eat fresh food. In the future, taikonauts on Mars may grow vegetables like carrots and lettuce.
Taikonauts on Mars will probably have special machines. They’ll use these machines to change beans into food that tastes like meat or cheese. They probably won’t eat real meat or cheese because it won’t be possible to keep animals in space.
1. Which planet do taikonauts plan to go to next
___________________________________________________
2. How long will it take the taikonauts to get to Mars
___________________________________________________
___________________________________________________
Taikonauts / They plan to go to Mars next./ Mars.
It will take the taikonauts / them about six / 6 months to get to Mars./ About six / 6 months.
3. Why do the taikonauts eat dried food
___________________________________________________
____________________________________________________4. What may taikonauts grow on Mars in the future
___________________________________________________
____________________________________________________
____________________________________________________
Because dried food / it is very light and it doesn’t cost much money to carry it into space.
Taikonauts / They may grow vegetables like carrots and lettuce on Mars in the future./ Vegetables like carrots and lettuce.
5. What will taikonauts probably change beans into
________________________________________________
________________________________________________
________________________________________________
Taikonauts / They will probably change beans into food that tastes like meat or cheese. / Food that tastes like meat or cheese.
B. 书面表达
