You can drive faster than 30 miles per hour 相关知识点: 试题来源: 解析 B。解析:“Speed Limit 30”表示速度限制为30(英里每小时或者相关单位),意味着你的速度不应该超过30,A选项可以任意速度行驶错误;C选项必须精确地开到30英里每小时太绝对;D选项可以超过30英里每小时不符合这个标志的含义,所以B正确。
at 后面跟宾语，所以用what在这引导一个宾语从句，I thought 是个插入语，what在宾语从句中作主语相当于"a speed that".what相当于一一个名词+that。本句不能误当做定语从句而误选that或which。因为引导词前五先行词。
