[解析]
(1)词义猜测题。根据第一段中Sometimes two or three of my friends would join me in the sycamore,or in the maple down the street,or Mrs.DiMarco's old peach tree,some of whose stout horizontal branches allowed us to sit shoulder to shoulder,eating sweet fruit.(有时,我的两三个朋友会和我一起去梧桐树下,或者去街尾的枫树下,或者去迪马科太太的老桃树下,那些……横枝让我们可以肩并肩地坐在一起,吃着香甜的水果。)可知,这些树干可以承受几个孩子们坐在上面吃水果。由此推知,这些树干应该是粗壮的、结实的,stout与strong词义一致。A.Slim.苗条的;B.Bent.弯的;C.Smooth.平滑的;D.Strong.粗壮的。故选D项。
(2)段落大意题。根据第二段In my small town there are some kinds of trees,their branches spreading wide,open for business.But I have not yet seen a climber.Perhaps computer games have replaced tree climbing,or maybe the activity went the way of monkey bars,which came to be viewed as too risky and have largely disappeared from playgrounds.(在我的小镇有一些种类的树,它们的树枝伸展得很宽,开放营业着。但我还没有看到一个爬树的人。也许是电脑游戏取代了爬树,或者是这项活动走上了单杠的道路,单杠被认为风险太大,已经基本上从操场上消失了。)可知,第二段主要描述了镇上已没有人爬树,作者推测了这个现象的原因。因此,A项"孩子们不再爬树的原因"符合段落大意。故选A项。
(3)推理判断题。根据第三段中I have always believed that,since low﹣hanging branches provide no benefit to the tree,they must be meant for the child.Robert Frost understood this when he wrote(我一直认为,既然低垂的树枝对树没有好处,那么它们一定是给孩子的。罗伯特•弗罗斯特明白这一点,他这样写道……)可知,作者认为罗伯特•弗罗斯特的诗体现了树是给孩子们爬着玩的这一想法。故选B项。
(4)推理判断题。根据作者描述的小时候爬树的乐趣,结合倒数第二段中I grabbed the thing,and a moment later was sitting on a branch.Then the memories came flooding back.The old sycamore,the friends,and finally,the reluctance to return to earth when the parental call to supper came.(我抓住了那东西,不一会儿就坐在了一根树干上。然后记忆如潮水般涌上心头。老梧桐树、朋友,最后,当父母喊吃晚饭时对回到地面的抗拒。)可知,作者在树上体味到了美好的回忆,想让学生一同体会爬树的快乐。由此推知,作者认为学生错过了爬树的乐趣。A.The explanations to his question.对他问题的解释;B.The fresh air above the tree.树上的新鲜空气;C.The pleasure of climbing trees.爬树的乐趣;D.The sense of safety on earth.地球上的安全感。故选C项。
