车里的乘客可以手动控制该系统，但在很多情况下如果这样做，就会自动向该账户的管理员（如家长或雇主）发送一条电子邮件信息，提醒他们有人正在使用移动电话。

我们正在寻找价格最适宜的 5.53和7.94a(型号)的挂钩，我们每月需要需要10000到15000片(件)，全部现金交易，尽可能给出你们最满意的价格，这样我们可以在新的一年里开始合作。
谢谢

个人感觉应该如此断句：
We looking for 5.53 and 7.94a hooks what the best price
we need 10000 to 15000 pcs per month
all cash
give your best rate possible
so that we can start business in the new year.

希望回答对你有帮助

因为在英语中名词一般来说是不可以修饰动词作状语成分的。a few seconds （几秒钟）就是一个名词，它不可以修饰looked （看），而在其前面加上介词for，变成了介词短语，就可以修饰动词作时间状语了。looked for a few seconds （看了几秒钟）。

您好，介词for在句中没有具体含义，for后接“段时间（a few seconds）”, 构成介宾短语。
