A．help out B．helped out
C．to help out D．helping out
解析：选D。本题考查非谓语动词。动词不定式作后置定语表示一个将要发生的动作，过去分词表示一个已经发生了的被动的动作，故B、C两项不符合题意。句意：旅客们同那几个在暑假临时帮忙充当列车员的大学生聊天。

8．Most parents are not ________ the danger of their babies’eating jelly，which causes most unfortunate incidents to happen.
A．well aware to　　　　　　B．very aware of
C．aware that D．well aware of
解析：选D。考查形容词用法。空白处后面不是句子，故排除C项；aware后面接of，故排除A项；另外表示“清醒地，充分地认识到”时，表语形容词aware的修饰语应使用well，不用very。
【教材原句】　There were other creatures that I didn’t want to get too close to－an eel with its strong sharp teeth，with_only_its_head_showing_from_a_hole，watching for a tasty fish(or my tasty toe！)；and the giant clam half buried in some coral waiting for something to swim in between its thick green lips.(P24)
还有一些其他的动物，我不想太靠近它们——一条带有利齿的海鳗，从洞穴里探出头来，望着可供美餐的鱼过来(或者在等着我美味的脚趾伸过去！)；一个巨大的蛤蜊半掩在珊瑚礁中，等待着有什么东西游过来，游到它宽厚的绿嘴唇中去。
【句法分析】　“with复合结构”表示动作或伴随情况，在句中一般作定语或状语。它的构成形式为with＋名词＋形容词/副词/现在分词/过去分词/动词不定式/介词短语。
(1)with＋n.＋介词短语
①The little girl came to a stream，with red flowers and green grass on both sides.
小女孩来到一条小溪边，小溪的两岸长着红花绿草。
②The teacher entered the classroom with a thick dictionary in his hand/under his arm.
老师进了教室，手里拿着一本厚字典/胳膊底下夹着一本厚字典。
(2)with＋n.＋adj.
③I like sleeping with all the windows open.
我喜欢开着窗子睡觉。
(3)with＋n.＋to do sth.
④With all the clothes to wash，I will be very busy today.
所有的衣服都要洗，今天我将会很忙。
(4)with＋n.＋doing sth.
⑤Their teacher is a young girl with long hair covering her shoulders.
他们的老师是一个长发披肩的年轻姑娘。
⑥With the boy leading the way，they had no difficulty in finding the house.
有那个男孩领路，他们很容易就找到了那栋房子。
(5)with＋n.＋done
⑦With his homework finished，the boy went out to play.
做完作业后，那男孩出去玩了。
(6)with＋n.＋adv.
⑧With her mother away，the little girl felt lonely.
由于妈妈离开了，小女孩感到孤独。
9．You have no idea how she finished the relay race________her foot wounded so much.
A．for　　　　　　　　　B．when
C．with D．while
解析：选C。句意：你根本无法体会，在脚伤得那么厉害的情况下她是怎样完成接力比赛的。这里是一个“with＋n./pron.＋done/adj.”的复合结构。要注意her foot wounded so much 不是一个完整句子，所以不能用连词when，while，for 引导，选B项可以这样改 when her foot was wounded so much。
[即境活用]
作文指导
提纲类作文
【体裁导航】
提纲类写作也是情景作文的一种，是通过给出段落提纲或者给出关键词语、短语等提示的一种“引领”性的写作。
无论是英语的段落主旨句、提纲提示，还是汉语的词组或短语等引导写作思路，进行习作时，毕竟减少了审题环节，也不用谋篇布局、重组语序，所以，在写作练习的初级阶段，这种习作形式尤其受到师生的欢迎。
做这类写作题要特别注意以下三点：
1．要按照所提供的“纲”的思路而写；
2．要考虑提供的各“点”之间该用什么样的连接词、连接句，以及上下句之间的关系；
3．看有无题目要求，有无词数限制，有无逻辑悖理现象(观点不要悖理或前后矛盾)。
总之，能做到循“纲”蹈“句”、“纲举目张”，此类写作便能顺利完成。
【写作要领】
一、审题
1．体裁：题目中已明确给出可以写记叙文也可以写议论文。
2．时态和人称：如果写记叙文，应是结合过去发生的事件来说明怎样有一个好的心情，所以应用过去时态和第一人称。如果写议论文，则应该用现在时态和第三人称。
二、谋篇
1．记叙文的篇章结构应为：
Para.1：描述过去发生的一件令人心情不好的事情以及由此产生的不良情绪。
Para.2：讲述如何从坏心情转至好心情的。
2．议论文的篇章结构为：
Para.1：提出问题：好心情的重要性。
Para.2：分析问题：产生坏心情的原因。
Para.3：解决问题：调整心情的方法。
三、注意事项
提纲作文虽然给出了写作的要点，但要点非常简略，因而还需要对要点进行丰富和拓展。
【范文点评】
Turning a bad mood into a good one
①At the end of the last semester，I got a C in the English examination.②When I knew the result，I couldn’t hold back my tears.③My mood was terrible and I thought the world was coming to an end.④I feared to see my English teacher and I thought my classmates would laught at me.⑤My parents weren’t satisfied with me and maybe they would scold me.⑥So I even wanted to leave my school and family.
⑦But after a while，I found I was wrong for I came to realize “Failure is the mother of success”．⑧What I should do was to find the reason why I got so bad a result.⑨And I thought this was a lesson to me and it helped me to find my shortcomings.⑩Maybe it could help me to improve my English.?So my bad mood turned into a good one.
1．文章标题，不要遗漏
本段为造成心情不佳的事件以及造成的影响，具体如下：
(1)①言简意赅地点明导致心情不佳的事件。
(2)②③为具体心情不佳的表现。
(3)④⑤为导致心情不佳的心理原因。
(4)⑥为心情不佳造成的影响——想离家(学校)出走。
(5)综上所述，整个事件的叙述娓娓道来，语意连贯，步步深入。
2．本段为“我的心情是如何由坏变好的”。具体过程如下：
意识到“失败是成功之母”——自我反省——吸取教训——提升英语——心情变好。
3．本文作者心情由坏变好的原因就是“自我反思，不放弃，继续努力”。当然也可以借助外力，如老师、父母的教导，书中的某一句话等都可以成为心情变好的原因。
【类题尝试】
(2011年山东潍坊质检)假如你是李华，你们学校最近开展了创建“平安校园”的活动。你们班为此组织主题班会，请你用英语写一篇发言稿，谈一谈你对如何创建“平安校园”的一些想法。短文应该包括下面的内容：
1．安全意识的重要性；
2．在运动中要注意安全；
3．在校内要注意人身安全；
4．同学间发生矛盾时，一定要保持冷静、理智；
5．逐步将“平安校园”活动转化为全体师生的实际行动。
注意：
1．不要逐句翻译，可适当增加细节以使行文连贯；
2．词数：120左右；
3．文章开头已给出，不计入总词数。
参考词汇：校园安全safety at school
My dear classmates，
There is no denying that safety plays an important part in our daily life.Recently our school has carried out a program aimed at making our campus a safe place to stay on.
______________________________________________________________________________________
One possible version：
My_dear_classmates，
There_is_no_denying_that_safety_plays_an_important_part_in_our_daily_life.Recently_our_school_has_carried_out_a_program_aimed_at_making_our_campus_a_safe_place_to_stay_on.
I consider this as indeed a good practice，which will make us aware that safety should always come first in our daily life，whether when we stay at school or outside it.When we are doing sports，we should attach importance to the safety and avoid being hurt.
Furthermore，when we get into trouble with our classmates，we should remain calm and avoid any form of fighting，which may only bring suffering and pain to us mentally and physically.
