1.考查细节理解。根据第二段中的“Frmed by vlcanes at the bttm f the sea, the Hawaii islands are like a necklace in the middle f the Pacific Ocean, 6,000 kilmeters ff the west cast f Mexic.”夏威夷群岛是由海底的火山形成的，就像太平洋中部的一条项链，距离墨西哥西海岸6000公里。可知，夏威夷群岛是由海底火山形成的。由此可知，C项表述错误。故选C。
2.考查推理判断。根据第一段中的“Beautiful sandy beaches, active vlcanes (火山），a great canyn (溪谷) and special histry and culture add up t create its famusly rmantic atmsphere.”美丽的沙滩、活火山、大峡谷以及独特的历史和文化，造就了它著名的浪漫氛围；以及第七段“Hawaii's reputatin fr rmance was spread when Hllywd started t use its typical music in mvies in the 1960's.”20世纪60年代，当好莱坞开始在电影中使用夏威夷的典型音乐时，夏威夷的浪漫名声就传开了。可推知，夏威夷是著名的旅游胜地。故选D。

C【答案】 D.CA
【解析】这是一篇说明文。文章介绍了自1900以来，过去120年来美国最强大、最具破坏性的飓风。
【点评】考查阅读理解能力。本题考点涉及细节理解的考查，是一篇自然类应用文。要求考生在读懂文章大意的前提下，通过仔细查找，对比原文和选项，进行词义转换，选出正确答案。

2.根据Cstliest hurricanes部分第一句“Hurricane Katrina is nt nly the cstliest-ever US hurricane but als the mst expensive natural disaster in the cuntry's histry.”（卡特里娜飓风不仅是美国有史以来最昂贵的飓风，也是美国历史上最昂贵的自然灾害。）可知，给美国造成损失最大的飓风是卡特里娜飓风。故选C。
3.根据Deadliest hurricanes部分第一段第一句“The categry-4 Hurricane Galvestn made a surprising landing alng the Texas cast n September 8. 1900. ”（1900年9月8日，4级飓风加尔维斯顿在德克萨斯州海岸意外登陆。）和第二段最后一句“It remains the deadliest weather disaster in the US histry as it gave the peple n time t mve ut.”（它仍然是美国历史上最致命的天气灾难，因为它让人们没有时间撤出去。）可知，因为它让人们措手不及，所以加尔维斯顿飓风成为美国最致命的天气灾害。故选A。
V.【答案】 C；F；A；B；G
【解析】本文是一篇说明文，自然灾害是可怕的事情，当孩子们表现出对自然灾害的恐惧时，文章介绍了五个方法来帮助孩子们减少恐惧。
（1）考查对上下文的理解和推理判断能力。根据第一段可知，根据空后“But talking can help children feel safer and less afraid f the future.”但是交谈可以帮助孩子们感到更安全，对未来少一些恐惧，可知，C选项中的talking以及natural disasters符合本段主题，且和下文呈转折关系，故选C。
（2）考查对上下文的理解和推理判断能力。根据空前的“When children are allwed t talk abut their fears, they feel safer. Smetimes, the best thing an adult can d is just listen.”当孩子们被允许谈论他们的恐惧时，他们会感到更安全。有时候，成年人能做的最好的事情就是倾听，可知，F选项中的fear和listen与前文关键字相契合且内容（无论恐惧是什么，重要的是倾听和耐心对待孩子）与前文呼应，故选F。
（3）考查对上下文的理解和推理判断能力。根据文章结构可知，可知空处是段落的主旨句。再根据空后内容可知，A选项questins和后文内容相契合，且顺承下文内容“When answering their questins, it is best t give shrt, hnest answers. If yu d nt knw the answer, yu can be hnest and say that yu d nt knw.”在回答他们的问题时，最好简短、诚实地回答。如果你不知道答案，你可以诚实地说你不知道，故选A。
（4）考查对上下文的理解和推理判断能力。根据空后可知，ne way和B选项中ways相契合，B. There are many ways t d this.“由很多方法可以做到这一点”承接下文，故选B。
（5）考查对上下文的理解和推理判断能力。根据空前“Hwever, she lved t write.”然而，Heshani 喜欢写作；以及空后“Writing pems was a way fr her t share her fears since she did nt like t talk abut them.”写诗是她分享恐惧的一种方式，因为她不喜欢谈论它们，可知，G. And she ften shared her feelings abut the tsunami in her pems.“她经常在她的诗歌中分享她对海啸的感瘦”是并列关系，且承接下文，故选G。
【点评】本题要求在理解细节信息的基础上，着重考查对上下文的理解和推理判断能力。

【解析】本文是一篇记叙文，讲述了作者学校在7月10日组织的一次登山活动。
（1）句意：为了鼓励学生进行户外运动，我们学校在7月10日组织了一次登山活动。encurage sb.t d，固定短语，“鼓励某人做”故take前加t。
（2）句意：为了鼓励学生进行户外运动，我们学校在7月10日组织了一次登山活动。在具体某一天用介词n，故at 改为n。
（3）句意：我们数百人参加了这次活动。take part in固定短语，“参加”，故删掉 part 前的 the 。
（4）句意：一路上我们聊天，唱歌，笑，享受新鲜的空气和美丽的风景。讲述的是已经发生的事情，用一般过去时，故laugh改为laughed 。
（5）句意：一路上我们聊天，唱歌，笑，享受新鲜的空气和美丽的风景。scenery“风景”，是不可数名词，没有复数形式，故sceneries 改为scenery 。
（6）句意：当一些人落后了，其他人会来帮助那些需要帮助的人。，固定短语，“一些人……，其他人……”，故ther改为thers。
（7）句意：大约两个小时后，我们都到达了山顶。tw hurs later，“两小时以后”，故late改为later。
（8）句意：沐浴在阳光下，远处的城市看起来美极了。我们高兴地跳着欢呼。bathe与the city在逻辑上构成动宾关系，过去分词作状语，故Bathing 改为Bathed 。
（9）句意：沐浴在阳光下，远处的城市看起来美极了。我们高兴地跳着欢呼。根据语境上下文为并列关系，故but改为and。
（10）句意：多美好的时光啊！此处应是hw引导的感叹句，hw修饰wnderful，故What改为Hw。
