解答 BACDC
46  B  詞義推斷題．根據(jù)"Higher hotel prices，airline capacity（容量） cuts and rising travel demand mean travelers will have to work harder to find a good deal in 2013．"可知，較高的酒店價(jià)格，航空公司運(yùn)力（容量）的削減和旅游需求上升意味著旅客將不得不更加努力地工作，由后面but轉(zhuǎn)折推斷出有些在線工具能夠幫助你的假期費(fèi)用在可控制范圍之內(nèi)．故選B．
47  A  推理判斷題．根據(jù)"It also finds sales from Allegiant and Southwest，which typically aren't listed on major airfare（機(jī)票）search engines．"可知，從銷售的Allegiant和西南航空公司，通常售主要機(jī)票的搜索引擎都沒有上市．因此Allegiant是航空公司．故選A．
48  C  細(xì)節(jié)理解題．由倒數(shù)第三段"If you already know where you want to go，use itasoftware．com to find the cheapest dates to fly．"可知，如果你選擇了一個(gè)假期的目的地，Itasoftware．com能幫助找到最便宜的起飛日期．故選C．
49  D  推理判斷題．通讀全文可知，這些網(wǎng)站介紹主要是為那些想找便宜機(jī)票度假的人們準(zhǔn)備的．故選D．
50  C   推理判斷題．由倒數(shù)第二段"Its Price Predictor can determine how likely a fare is to rise or fall during the next seven says"可知，website Bing．com網(wǎng)站能夠預(yù)測(cè)未來一周內(nèi)的價(jià)格趨勢(shì)．故選C．

點(diǎn)評(píng) 做閱讀理解時(shí)要快速的瀏覽全文，把握文章主旨大意，帶著問題回到原文，尋找細(xì)節(jié)或概括相應(yīng)的答案，最后要理清作者寫作思路．

Must-sees include Derbyshire，called"the heart of England"and home to the National Park．The great peaks were the muse（創(chuàng)作靈感）of the Bronte sisters （and if you love the book Jane Eyre，you can visit North Lees hall，where the real Eyre family once lived）．

Let's not leave out the Wessex region，where one can see one of England's greatest mysteries，Stone Henge．You can also go to the City of Bath，which has been famous for its medicines springs since the Roman times．Other popular tractions include Salisbury Cathedral，and landscaped（景色優(yōu)美的） gardens of Stourhead，and the cobbled（用鵝卵石鋪的） streets of Shaftesbury．This is also home to Oxford，one of the world's most famous universities．
Art lovers will also like a visit to East Anglia，whose landscapes inspired the painter Constable （he was born in Dedham village）．This is also home of the University City of Cambridge，and the famous architectural（建筑上的） attraction，King's College Chapel．Be sure to visit the aircraft museum of Duxford．

20．When you were a child you had a pure mind which was free from worries and anxieties．However，as time goes by，you're faced with so many problems in life．Below are five techniques that can help you get relaxed．
1．Mind your own business．
Yes，please mind your own business．When you start being concerned about things which are not related to you，you lose your control on your thought process，which often has negative results disturbing the mental peace．Basically，your mind starts wandering here and there．So next time an unnecessary thought comes to your mind，think whether this is really something you should be worrying for？If not，keep it away and focus on something positive，practical and fruitful．
2．Surround yourself with positive people．
Overlook negative comments and stay away from negative souls．When someone is negative，he spreads negativity and you get affected．Staying with such people will have long term influence on your character so think about your company．
3．Don't think about others too much．
Remember：Small minds discuss people； Average minds discuss events； Higher minds discuss ideas and Great minds act in silence．Don't allow your brain to compare yourself to others as this is an insult （侮辱） to yourself．Don't be jealous； it's a heart killing disease，get rid of it as soon as possible．When you are jealous you focus on finding faults in others even if they don't have．This poisons your soul and steals the mental peace．
4．You can't keep everyone happy．
Don't be oversensitive （過于敏感的）．Be natural in what you do．Be positive and constructive in your deeds and then don't really care too much about others．Be aware，don't apply this to too closed relations．Develop trust to build up powerful relationships．
5．Don't believe yourself to be unlucky．
Remember this：Bad luck happens to everyone．It's not your fault at all．Time，whether good or bad，passes quickly．Develop the power of not looking back into your past．Believe in the power of Now．Believe in your skills．Work hard and you will get what you have been entitled for．Be patient and see what has been planned for you．
With these recommendations，I believe if you can make it，it's probable that you can bring changes in your lifestyle and get back your mental peace．
67．This passage is written for those who want toD．
A．seek learning skills
B．find positive people as friends
C．make their mind pure
D．get mentally peaceful and relaxed
68．The underlined word"Overlook"can be replaced byA．
A．Ignore  B．PassC．Master D．Support
69．The underlined sentence meansA．
A．People with different minds do different things
B．people should discuss different aspects of life
C．people should never compare themselves with others
D．people should never be jealous，or they'll be poisoned
70．Which of the following should NOT be done according to the five techniques？B
A．Stay with positive people．
B．Care about the business of strangers．
C．Be sincere with others and never care too much about them．
D．Believe in the magic power of what the present can bring you．
