32、e doing about these problems？(但是我们对这些问题做了什么呢？)切题。该项中的these problems指的就是上文中的acid rain and the ozone hole。故选A。2下文提示“通过这种方式，我们有能力影响零售商向我们出售这些所谓的绿色产品。”承接下文，G项For example, when we walk into a supermarket we can choose to buy environmentally friendly products.(例如，当我们走进一家超市时，我们可以选择购买环保产品。)该项中的environmental

40、此处指“会宽恕的人会表现出更少的愤怒和更多的希望”。此处用less与后面的more在形式上保持一致。4考查非谓语动词。allow sb.to do sth.是惯用搭配，意为“允许某人做某事”，故填to feel。5考查定语从句。“_5_ gives you pleasure”是定语从句，修饰先行词something，空处是关系词且作定语从句的主语，因为先行词是不定代词，所以只能用关系代词that。6考查名词。空处作wait for的宾语，且由空前的an可知，空处用名词单数形式。7考查冠词。same前常用定冠词the，意为“相同的”。8考查非谓语动词。mean在此处意为“意味着”，后面要用动词ing形式作宾语，意为“宽恕不一定意味着接受让你烦恼的那个人的行为”。9考查介词。from.perspective是惯用搭配，意为“从角度”。10考查反身代词。此处表示“你可以以那个人的观点给自己写信”。当作宾语的代词与主语指同一人或物时，这个代词要用反身代词。故填yourself。
