180.Many products had specially-designed labels to make them seem environmentally friendly, but in fact many of these symboEs mean nothing.

英语四级译文:
很多产品都有特别设计的标签，让它们看起来是环保的，但实际上，很多这样的标签没有任何意义。

四级词汇讲解:
本句是由but连接两个简单句所组成的复合句。

label意为“标签;商标”。如:
Have you attached labels to the luggage?你给行李贴上标签了吗?

symbol意为“符号;标志，象征”。如:
The Cross is the symbol of Christianity.十字架是基督教的象征。

英语四级考点归纳:
本句中的environmentally friendly意为“对环境友好的;不污染环境的”。英语中有很多这样用副词限定形容词来修饰事物的表达。如:

※ Shangdong is an economically important province.山东是经济大省。

※ His goal is to build two new primary schools and help 500 educationally-deprived children to return to school in the next year.他的目标是，在明年新建两所小学，并帮助500名失学儿童重返校园。
