图片上手写部分和打印部分,感觉说的是下面的语法：
虚拟语气：
（1）虚拟语气在条件从句“If.,.”及让步状语从句中,一般指的是一种假设、猜测,不是事实.这样有两种情况,如下：
A.假设情况可以发生、实现.从句用一般现在时,主句用将来时态,如 If it is sunny tomorrow,I will go to buy some beautiful skirts.
B.非真实的假设,是不可能发生、实现的,与事实不符.从句用一般过去时,主句用情态动词的过去时.事实可以是过去和现在的事实.
If I were you,I would give her a warm hug.()
If I were a birg,I would fly to the sky.(与现在的事实相反)
If it rained tomorrow,they wouldn't go out side.（与明天的事实相反）
If I had taken your advice,I wouldn't have made a mistake.
（2）虚拟语气在宾语从句、同位语从句及表语从句中,一般表示说话人的愿望,要求、命令、建议等.
I suggest that we (should) set off at once.
I demanded that he (should)answer me immediately.
因果连词：
“.,so.” 讲的是 “因为.,所以.”,
这个表示因果的句子,在英文中,"because "和'So' 只能出现一个.
这个上面的得分,可以用来在文库中下载东西吗?
我想下载“混凝土”的相关资料,可是没有金币,是穷疯了.帮忙给我点吧
