29、emperatures，and the faster growth they spur，probably account for some of the drop.Another factor，Pretzsch says，is more nitrogen in the soil from agricultural fertilizer (化肥) and vehicle exhaust.Previous studies have linked increased fertilizer use to decreased wood density.Above all，the study sugges

42、. We shared our during the meeting. All of us held the same view environmental protection is so important for our life.文章大意：这是一篇记叙文。文章主要讲述了作者和父母为了支持“绿色出行，从我做起”的环保活动，采用骑自行车和乘坐公交车的方式上学上班的故事。解析：1考查过去分词作定语。句意：为了支持名叫“绿色出行，从我做起”的活动，我和父母谈论了我的想法。分析句子结构可知，name(命名)用非谓语动词形式，它的逻辑主语activity(活动)和它之间是被动关系，要用过去分词。故
43、将name改为named。2考查时态。句意：为了支持名叫“绿色出行，从我做起”的活动，我和父母谈论了我的想法。联系下文可知，本文讲述过去发生的事情，应该用一般过去时。故将talk改为talked。3考查现在分词作伴随状语。句意：他们非常支持，说以后他们再也不开车上班了。分析句子结构可知，句中“say”是非谓语动词，它的逻辑主语they和它之间是主动关系，故用现在分词形式。故将say改为saying。4考查固定搭配。句意： 他们非常支持，说以后他们再也不开车上班了。根据句意，“开车去上班”的固定表达为drive to work。故在drive后加to。5考查人称代词。句意：在接下来的几周，正如我
44、们所承诺的那样，我每天骑自行车上学，而我的父母坐公交上班。该句陈述了“我”和父母共同的行为，所以应该用“我们”来指代。故将they改为we。6考查固定用法。句意：虽然很累，但我们感觉很开心。根据although不能和but连用的原则，所以本句应删除but。故删除we前的but。7考查形容词。句中的felt是感官动词，其后接形容词作表语。故将happily改为happy。8考查冠词。句意：上周五，召开了一次班会。根据句意，此处不是特指，且meeting是可数名词的单数形式，故用不定冠词a。故将the改为a。9考查可数名词的数。句意：在会议上我们分享了我们的想法。句中的thought是可数名词，根据句意“我们的想法”应为复数形式。故将thought改为thoughts。10考查同位语从句。句意：我们所有人都持同样的观点，那就是环保对于我们的生活很重要。分析句子结构可知，view后面是同位语从句，对其进行补充说明作用，且从句的成分和意思都完整，所以用连接词that。故将which改为that。
