语篇解读：本文是一篇记叙文，主要讲述了一名男子的爱犬因为高温面临生命危险，于是这名男子向公园管理员求助，并在管理员的热心帮助下挽救了狗的生命。

1．A.reportedB．stated

C．witnessedD．changed

解析：选C根据第三段可知，Lexie和她的朋友遇到了一个男子，他的爱犬出现了问题；再根据下文管理员救狗的情节和Lexie回家后将事件发布在网上可知，当事件发生时她和她的朋友在场，目睹(witnessed)了这一善举。

2．A.slightlyB．severely

C．casuallyD．hardly

解析：选B由第二段中的“Thetemperaturewasrisingto90degrees”及下文救狗的内容可知，它当时病得很严重。severely“严重地”；slightly“略微，稍微”；casually“不经意地”；hardly“几乎没有”。

3．A.boughtB．threw

C．desiredD．donated

解析：选D根据下文“tosavethepup”可知，为了救中暑的狗，Lexie和她的朋友把水赠送给了狗。donate“赠送”；desire“渴望”。

4．A.sorryB．afraid

C．ashamedD．glad

解析：选B下文提到狗主人向公园管理员求助，由此可以推测出一行人送出去的水是不够的，因此不免会担心(afraid)。

5．A.sweatingB．hurting

C．strugglingD．starving

解析：选C根据空前的“itwouldn'tbeenoughtosavethepup,afterseeinghowmuchthedogwas”之间的因果关系可以推知，正是因为看到狗在挣扎，所以他们才担心这些水不够救狗，故“struggling”(挣扎)符合语境。sweat“流汗”；hurt“感到疼痛”；starve“挨饿”。

6．A.lovingB．strong

C．unwillingD．generous

解析：选A根据上文中的“Tootiredtocarrythedoghimself”以及下文中的“calledtheparkrangers(公园管理员)quickly”可知，这位主人一直在想办法挽救自己的爱犬，这说明他是一位有爱心的(loving)主人。generous“慷慨的”。

7．A.temperatureB．wish

C．requestD．location

解析：选D狗主人联系了管理员，根据常识可知，如果想及时获救的话，就要告诉管理员他们所在的位置(location)。

8．A.foundB．saved

C．tookD．followed

解析：选A根据后一句“Kristhenliftedthehugedogontohisshoulders...downthemountain”可知，管理员很快在山上发现了他们，然后把狗背下山进行救助，故此处found符合语境。

9．A.pushingB．asking

C．orderingD．carrying

解析：选D参见上题解析。

10．A.centerB．bottom

C．streamD．forest

解析：选C由后面的“Krislaidhiminthewater”可以推知，他们走到了一条小河(stream)边。

11．A.hadB．poured

C．heldD．sneezed

解析：选B在中暑的情况下，为了给狗降温，Kris把河里的水泼(poured)在狗的身上。pour“倾倒”；sneeze“打喷嚏”。

12．A.fairB．strange

C．familiarD．good

解析：选D公园的管理员在天气炎热的情况下救助一只狗，这当然是一种非常好的行为。所以此处是说当Lexie回到家时，她把这一善举(gooddeed)发布在网上。

13．A.surpriseB．admiration

C．mercyD．understanding

解析：选B根据空前的“itspreadwith35,000peoplesharingthepost”可知，这个帖子在网上快速传播，这也说明大家都对这个管理员表示敬佩(admiration)。surprise“惊讶，意外”；mercy“仁慈，宽恕”；understanding“理解，领悟”。

14．A.luckyB．poor

C．braveD．cool

解析：选A此处是Lexie在帖子中对管理员救狗行为的评价，根据下文“putevenanimalsbeforethemselves”可知，能有这样的管理员，Lexie认为他们很幸运(lucky)。

15．A.requiresB．demands

C．deservesD．reflects

解析：选C根据空后的“recognitionforhisbravery,selflessness,andstrength”可知，此处是说这位勇敢、无私、强大的管理员值得(deserves)大家的认可。require“要求”；demand“要求”；reflect“反映，表明”。

语篇解读：本文是一篇记叙文。在家乡的山里一边开车，一边欣赏秋天的景色，这时遇上了一头雌鹿和它的小鹿。等待它们安全离开后才继续行驶。

1．Driving考查非谓语动词。此处为动名词短语作主语。

2．leaves考查名词复数。leaf是可数名词，此处应用复数形式。

3．hadbecome考查时态。开车经过是发生在过去的事情，此处指过去的过去，所以用过去完成时态。

4．a考查冠词。此处为泛指，所以用不定冠词。

5．Knowing考查非谓语动词。know和逻辑主语I之间是主动关系，故用现在分词形式。

6．frightened考查形容词。frightened意为“害怕的”。

7．them考查代词。指代鹿妈妈和幼鹿。

8．safe考查形容词。keepsb./sth.safe意为“保持某人或某物的安全”，此处用形容词safe作宾语补足语。

9．that考查固定句型。Itseems/seemedthat...意为“看来……”。

10．largely考查副词。此处用副词修饰动词left。UNIT2课时跟踪检测（二）语言运用综合练
