急求英语高手帮忙做一下以下判断题呀!题目及要求如下：

V 1. We recommend you to be careful about opening e-mail attachments.
V 2. In the lower part of the right side of the Save As dialog box,click Options.
（可以改为 On the lower right side of .,但原来的用法也无大碍）
X4. Really appreciated that you can address this issue in such a prompt manner.
Really appreciated that you addressed this issue in such a prompt manner.
（从 in such a prompt manner 判断,这个问题已经解决了）

三句完全正确； recommend sb to 有提醒某人做某事的意思，不一定要用虚拟的。
I wouldn't recommend him to go there.这是词霸上的例句。是这样啊~那么，opening e-mail attachments是啥意思？题也没说一定是语法错，说不定有名词等搭配错呢？其他俩道再看看有否语法之外的错吧~比如下一道 In the lower part ...

1要去掉to,4 appreciated 后要加it
