7. You must keep your eyes open if you are going to make your trip to the United Kingdom worthwhile.如果想使你在英国的旅程有意义，你必须睁大双眼。

解读：1)句中的keep your eyes open和make your trip worthwhile都是“动词+宾语+形容词作宾补”结构。

He found the room open.他发现房间是开着的。

The rain made the ground wet.雨使地面浸湿了。

2)worthwhile adj.值得做的,常用于It is worthwhile to do sth./doing sth.中。

I don’t think it is worthwhile.我认为不值得做这件事。

It is worthwhile discussing/to discuss the question.讨论一下这个问题是值得的。

注意：worth, worthy 和worthwhile的区别

worth现在英语中被看作介词，因为它后面必须带名词或动名词。后接动名词时以主动形式表达被动的意思，接名词时须接表示价值、代价的名词。

worthy是形容词，在句中作表语或定语。作表语时，用be worthy of +n./doing sth. 或 be worthy to be done 结构。

This book is well worth reading.这本书很值得一读。
