答案1.C [从上文中“Nubs was shaking”可知，这只狗受伤严重，因而几乎站立不稳。D项迷惑大，根据上句“circled American soldiers for food”可推断狗还是站着的，故D错。]
2.D [根据下文“He and his men immediately treated the wound”可知Dennis不忍心看到Nubs受苦。]
3.A [由下文“Ten days later，Dennis’s unit was back”可知，Dennis的支队不得不离开。]
4.D [上文强调狗受伤，体弱。这里选weak照应上文。]
5.B [从下文“he saw Nubs just outside the outpost”等句子可知，狗慢慢地跟着部队前进。]6.B [Nubs跟在部队后面，直至士兵“望不见”它。]
7.C [Nubs一路尾随部队到七十里外的哨所出乎Dennis的意外。]8.C [根据下文“From then on Nubs and the men slept in the same place，and ran around in the same ruins.”可知，狗与Dennis的支队再次接上头。]
9.D [从下文看养狗是不允许的，Dennis不得不把狗空运到美国。]
10.A [Dennis决定让狗继续过上好日子。]
11.B [把狗空运到美国，不是让它继续过流浪生活，A错。在Dennis看来，与以前相比，狗与他们在一起后过的是好日子，但战场上是不安全的，故选B。]
12.D [上次是Dennis救了Nubs这条狗，因此这次是Dennis和Nubs再次聚首。]
13.A [根据常识可知狗表示友好，应该是lick“舔”Dennis的脸。]
14.C [点题之句。上文谈论的是人与动物之间的友情和关爱，本句对此作总结，故选C。]
15.B [上下两句为转折关系，harmonious与violent对照。]
16.did [中间由but连接，所以两句应是对称的，谓语动词应是open，但一般为避免重复，用do代替，此处用did与前面保持时态一致。]
17.personal [information是名词，前面用形容词修饰。personal“个人的”。]
18.which [which引导非限制性定语从句，此处先行词不是一个单词，而是整个句子。]

20.until [not...until...“直到……才……”。本句意为：直到你注意到不对时，才会知道有人盗用了你的身份。]
21.a [不定冠词a表泛指的“一个”。a credit card account意为“一个信用卡账户”。]
22.or [这里列举了三种个人信息被盗用的情况，or表示“或者”。]
23.been stolen [has说明是完成时态，又因为是被偷，所以用has been stolen。]
24.take [此处suggest作“建议”讲，后面的that从句应用虚拟语气，即用should do的形式，should可省略。]
25.for [ask sb.for sth.“向某人要某物”，固定搭配。]
26.A [推理判断题。根据文章第一段最后一句可知环保是这种太阳能插入式充电站的最大卖点，因此答案是A。]
27.D [推理判断题。根据文章第二段第一句“The Solar PlugIn Station has gone on show in Chicago”和第二句“The Solar PlugIn Station on show is part of the vital infrastructure required for electric vehicles in Chicago”可知，芝加哥在促进这种电动交通工具的应用。]
28.A [细节理解题。根据文章第一句可知a项正确;b项的all cars错误;c项没有被提到;根据文章第五段最后一句可知d项正确;根据文章最后一段可知e项正确。因此A项正确。]
29.B [推理判断题。根据文章第一句可知随着越来越多的插入式电动交通工具的出现，人们需要越来越多的充电点，因此B项正确。]

33.A [主旨大意题。在文章最后一段中作者告诉我们要注意饮食，加上适当的锻炼，才能保持身体健康。选项B、C、D都不全面。 ]
34.B [词义猜测题。由第二段第二句“The diary group has food like milk，cheese and sour milk.”可知milk，cheese和sour milk都是奶或奶制品。]

第一节 基础写作
参考范文
Tourism can benefit us a great deal.For one thing，it will help the city’s economy and advance the wellbeing of local people; for another，we will have nice parks，the firstclass roads and grand buildings and also we will get lots of chances to communicate with tourists from all over the world.
If tourism grows too quickly，people will move from their early jobs to those concerning tourism and local industry will suffer.Too many tourists can crowd public places and cause some pollution.
I think it is necessary to develop tourism but first of all we should have a proper plan so that tourism should be developed steadily and efficiently.
第二节 读写任务
参考范文
Worried about environmental issues and a severe waste of resources，China will ban the free plastic bags，but it may not be universally welcomed while they provide convenience to consumers.
I think the ban is good both for us and for the whole world，which can reduce waste and save resources.As we know，oil is nonrenewable resource.Overuse of oil will bring us a series of troubles.Overuse of plastic bags will bring us lots of diseases.So，we can not wait to stop using them.Many countries，including those with developed economy，have bitten the bullet and banned plastic bags.
But everything is twosided.For the time being，people have really got used to using them，and they do give us lots of convenience.If we forbid using plastic bags，we should find ways to solve the problem.We consumers ought to bring cloth bags or shopping baskets instead of plastic bags.
