All of the above.

参考答案和解析
第三段首句指出“误导广告经常把卖方的观点描述得像事实一样”，然后给出Acme Cars广告的例子，接下来的两段提到有的广告把不相关品质与某个产品联系起来以达到某种效果，叫做“image making”，其中便出现Sparkle toothpaste的例子，而选项C“白猫洗得更白”也属于这一类型，因此这三种情况都仅仅反映了卖家的观点。

TV Shows and Long Bus Trips Long bus rides are like televisions shows.They have a beginning,a middlle,and an end-with commercials thrown in every three or four minutes.The commercials are unavoidable.They happen whether you want them or not.Every couple of minutes a billboard glides by outside the bus window.“Buy Super Clean Toothpaste.""Drink Good‘n’Wet Root Beer.""Fill up with Pacific Gas."Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of"You Need It!Buy It Now!" The beginning of the ride is comfortable and somewhat exciting,even if you've traveled that way before.Usually some things have changed-new houses,new buildings,sometimes even a new road.The bus driver has a style of driving and it's fun to try to figure it out the first hour or so.If the driver is particularly reckless or daring,the ride can be as thrilling as a suspense story.Will the driver pass the truck in time?Will the driver move into the right or the left-hand lane?After a while,of course,the excitement dies down.Sleeping for a while helps pass the middle hours of the ride.Food always makes bus rides more interesting.But you've got to be careful of what kind of food you eat.Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning.You know it will soon be over and there’s a kind of expectation and excitement in that.The seat,of course,has become harder as the hours have passed.By now you've sat with your legs crossed,with your hands in your lap,with your hands on the arm rests-even with your hands crossed behind your head.The end comes just at the right time.There are just no more ways to sit.The writer thinks that the end of the ride is somewhat like the beginning because both are______.

第一篇
Carbon Footprint
How often do you travel by plane?How much electricity do you use?
These days everyone is worried about the size of their carbon footprint.In order to reduce global warming we need to make our carbon footprints smaller. But how much CO2 are we responsible for?
A new book might be able to help.The Carbon Footprint of Everything looks at the different things we do and buy,and calculates the amount of CO2 all of the following created:the ingredients, the electricity used in the brewery，the equipment,the travel and commuting of the beer,and the packaging. It's amazing how many different things need to be included in each calculation.And it's frightening how much carbon dioxide everything produces.
But all of this can help us decide which beer to drink.From Berners-Lee's calculations,it's clear that a pint(568ml)of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer. This is because the imported beer has been transported from far away,and it uses more packaging. The local beer only produces 300g of CO2,but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket.
Berners-Lee has even calculated the carbon footprint of cycling to work.Nothing is more environmentally-friendly than riding a bike,surely?Well,it depends on what you've had to eat before. To ride a bike we need energy and for energy we need food.So if we eat a banana and then ride a kilometer and a half,our footprint is 65g of CO2.However,if we eat bacon before the bike ride,it's 200g. In fact,bananas are good in general because they don't need packaging,they can be transported by boat and they grow in natural sunlight.
So,does this mean that cycling is bad for the environment?Absolutely not,for a start,if you cycle,you don't use your car,and the fewer cars on the road,the fewer traffic jams.And cars in traffic jams produce three times more CO2 than cars traveling at speed.Cycling also makes you healthy and less likely to go to a hospital. And hospitals have very big carbon footprints!
So maybe it's time for us all to start making some changes.Pass me a banana and a pint of local beer,please.According to Berners-Lee,which of the following produces the most carbon dioxide?
A:A pint of local beer we drink.
B:A pint of imported beer we drink.
C:A banana we eat before a bike ride.
D:The bacon we eat before a bike ride.答案：B解析：细节题。根据原文可知以下产生的二氧化碳量分别是：A选项，一品脱当地酿造的啤酒为300克，B选项，一品脱进口啤酒为900克，C选项，骑车前吃的香蕉为65克， D选项，骑车前吃的培根肉是200克。
词义推断题。第三段第二句：原料、xxx所用的电量、设备、啤酒的运输和包装。由此可知A最合理，B’选项与原文的“设备”重复了，D选项同理，C选项与包装重复了。
推断题。从第六段可以看出骑车是环保的，产生的碳足迹是少的，其他选项都没有在原文中体现这个意思。
推断题。第五段最后一句：香蕉总体来说是很好的，因为它们无需包装，可以使用船只运输，并且在自然光照下生长。这些都是说香蕉产生的碳足迹少，并没有提到它是健康食品。A、B、D原文均有体现。
主旨题。本文大意是阐述了我们的碳足迹量有多少。A、B和C均只是原文中的一点。 -

第11题：
问答题Practice 2 You should spend about 40 minutes on this task. Write about the following topic: In countries where there is a high rate of unemployment, most pupils should be offered only primary education. However, others believe that higher education helps people find jobs. Discuss both sides and give your own opinion. You should write at least 250 words.正确答案： 【参考范文】
Being faced with a high rate of unemployment, many people begin to doubt the role or the purpose of receiving education, as high degree is not a stepping-stone to a successful career. Some people believe that a basic education can be enough to meet demands of job market and fulfill the requirements of a person's lifetime. However, others hold an opposite perspective on this issue. As far as I am concerned, unemployment has nothing to do with education itself, which is just not consistent with demands.
First of all, when it comes to basic education, it has at least obvious advantages: On the on hand, it is primary education that establishes the foundation of all subjects one should master, which can be frequently used in daily life. Moreover, only learning from the very basic level, one may have the chance to get to know something deeper in the future. On the other hand, and more importantly, through primary education, one can cultivate his desire and interest of learning. Without the interests in study, it is impossible for anyone to promote himself to higher levels. Like the foundation of a building, primary education is the foundation to build one's life education upon.
Furthermore, further education has its unique benefits: firstly, one can get the whole picture of a particular subject from higher education in college, which can benefit one's life constantly. Secondly, Uplifting one's life quality asks for two important elements: wealth and taste, which can be both gained from further education.. In other words, one can be a comprehensive person, not only learning his major, but also enjoying literature, art and music.
Lastly, it is a fantastic chance to meet and talk with people who share something in common in higher levels of education. Universities are like a stage or platform, on which people can consolidate the friendship they have for one another.解析： 暂无解析 -

短文理解
听力原文： In the United States, even if you decide that you do not want to borrow in order to go on vacation, it is still a good idea for you to have several major credit cards. These provide positive identification when renting an automobile and can be used for the deposit. The credit card receipts will serve as an accurate record of all hotel, plane, train, and restaurant expenses. The use of credit cards avoids the necessity of carrying large amount of cash, purchasing large amounts of traveler's cheeks and keeping track of them, or attempting to use personal checks in places other than your own locality.
Many major credit cards provide an instant cash service in case you run out of money. American Express, for example, has set up machines in major airports in which you can purchase traveler's checks using your American Express card.
21. The credit card receipts will serve as accurate record for all but which of the following choices?
22.Which of the following is not true about the use of credit card?
23.Concerning the advantages of credit cards, which of the following is true?
24.According to the passage, which card has set up machines in major airports?
(21)
A．hotel expenses
B．stock exchange
C．plane expenses
D．restaurant expenses

第15题：
资料：Imagine you went to a restaurant with your girlfriend, had a burger, paid with a credit card, and left. The next time you go there, the waiter or waitress, armed with your profile data, greets you with, “Hey Joe, how are you？ Mary is over there in the seat you sat last time. Would you like to join her for dinner again？” Then you find out that your burger has been cooked and placed on the table. Forget the fact that you are with another date and are on a diet that doesn’t include burgers.
Sound a little bizarre？ To some, this is the restaurant equivalent of the Internet. The Net’s ability to profile you through your visits to and interactions at websites provides marketers with an enormous amount of data on you——some of which you may not want them to have.
Are you aware that almost every time you access a website you get a “cookie”？ Unfortunately, it’s not the Mrs. Field’s recipe. A cookie on the Internet is a computer code sent by the site to your computer——usually without your knowledge. During the entire period of time that you are at the site, the cookie is collecting information about yourself, including where you visit, how long you stay there, and how frequently you return to certain pages.
While this may sound scary enough, cookies aren’t even the latest in technology. A new system call I-librarian Alexa——named after the legendary third century B.C. library in Alexandria, Egypt——does even more. While cookies track what you are doing at one site. Alexa collects data on all your web activities, such as which site you visit next, how long you stay there, whether you click on advertisements, etc. All this information is available to marketers, who use it to market more effectively to you. Not only do you not get paid for providing the information, you probably don’t even know that you are giving it.
Which of the following can best reflect the author’s attitude towards cookies and Alexa？A.Doubtful.
B.Approving.
C.Welcoming.
D.Optimistic.答案：A解析：本题考查的是细节理解。
【关键词】attitude;cookies；Alexa
【主题句】第4自然段Not only do you not get paid for providing the information, you probably don’t even know that you are giving it.你不仅不会因为提供这些信息而得到报酬，而且你甚至可能不知道你正在提供这些信息。
【解析】本题的问题是“以下哪一项最能反映作者对于cookies和Alexa的态度?”。A选项“怀疑的”；B选项“赞成的”；C选项“欢迎的”；D选项“乐观的”。根据主题句可知，作者对于cookies和Alexa持怀疑的态度，故选A。 -

Long Bus Ride
Long bus rides are like television shows.They have a beginning,a middle,and an end-with commercials thrown in every three or four minutes. The commercials are unavoidable.They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window."Buy Super Clean Toothpaste.""Drink Good'n Wet Root Beer.""Fill up with Pa-cific Gas."Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of"You Need It!Buy It Now!"
The beginning of the ride is comfortable and somewhat exciting,even if you've traveled that way before .Usually some things have changed-new houses,new buildings,sometimes even a new road. The bus driver has a style of driving and it's fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring,the ride can be as thrilling as a suspense story. Will the driver pass the truck in time?Will the driver move into the right or the left-hand lane? After a while,of course,the excitement dies down.Sleeping for a while helps pass the middle hours of the ride .Food always makes bus rides more interesting. But you've got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there's a kind of expectation and excitement in that. The seat,of course,has become harder as the hours have passed.By now you've sat with your legs crossed,with your hands crossed behind your head.
The end comes just at the right time.There are just no more ways to sit.What is the purpose of this passage?
A: To give the writer's opinion about long bus trips.
B: To persuade you to take a long bus trip.
C: To explain how bus trips and television shows differ.
D: To describe the billboards along the road.答案：A解析：第一段中介绍了乘客在坐长途车过程中所见的是广告牌。the commercials是“商业广告”的意思；billboard是“广告牌”的意思，即advertisements on the board。
全文主要介绍作者对乘车长途旅行的感受。因此选择A。
第一段作者说到“The commercials are unavoidable. They happen whether you want them or not.”商业广告不可避免，无论你是否需要，它都会出现。也说到“Only if you sleep...are you sparea me unenaing cry of‘Yon Need It！Buy It Now！’”只有睡觉才能躲避广告。由此可以推断出作者不喜欢沿途的广告牌。
根据文章第一段第一句和第二句“乘坐长途车就如同欣赏电视秀，有开端、有情节、也有结尾，每隔三四分钟插播商业广告”，选项B是正确的。
根据文章第二段第一句“旅程的开始是舒适并且有些兴奋的”和第三段第二句“你知道旅程将很快结束，就会产生一种期待和兴奋”选项A正确。 -
