19．這種收音機(jī)已經(jīng)很落伍了，不增加新功能的話很難有銷路．  （unless）This kind of radio is quite out of fashion，so it's hard to sell unless new features/functions are added （to it）．

分析 這種收音機(jī)已經(jīng)很落伍了，不增加新功能的話很難有銷路．

解答 答案：This kind of radio is quite out of fashion，so it's hard to sell unless new features/functions are added（to it）．落伍：out of fashion；增加新功能：add new feathers/functions；很難有銷路：be hard to sell；句意表達(dá)的是因果和條件，要用so連接結(jié)果狀語從句，unless連接條件狀語從句；句意表達(dá)的是客觀事實(shí)，要用一般現(xiàn)在時(shí)態(tài)來構(gòu)成．

點(diǎn)評 翻譯題在解題是首先要確定好句子的時(shí)態(tài)，然后要把握好短語表達(dá)，最后要注意句子結(jié)構(gòu)．

7．Are you still worried about overcharging for your luggage over the weight limit？An"Airport Jacket"containing up to 15kg luggage is designed to help frequent flyers bypass（繞過）airport baggage queues，reduce baggage fees and really lower the risk of lost luggage．
"With airlines beginning to charge for carry-on baggage as well as severely limiting 10aggage allowances for the low fare economy traveler，my partner and I have designed a jacket that can wear your laptop，tablet，two pairs of shoes，a pair of jeans，five T-shirts，a jumper and a camera，"designer Claire Murphy explains．"It totals 14 deep pockets，including 8 pockets at hip length，11 pockets at three-quarter length and 14 pockets at full length．"
Claire and Benke Murphy came up with the idea while traveling home with their newborn child．They had so much extra carry-on luggage that the airline tried to charge them $ 140 for it，more than the cost of their tickets．So they had to put clothes，chargers，diapers and toys into their pockets，until just over the weight limit．They escaped the tax，but everything sticking out of their pocket saw a pretty uncomfortable plane ride．
However，people have been raising questions about the usefulness of the Airport Jacket，especially the trouble of going through security checkpoints．They are arguing that having to take all out and then putting them back into the pockets is not worth the few tens of dollars you save on a checked luggage．
But Benke claims that walking through airport security is not an issue as long as you follow guidelines for carry-on luggage．"It only needs to be worn when checking in and at the boarding gate．What's more，Airport security is not looking at how you store your luggage but checking its contents．"
Its makers are currently running a crowdfunding campaign on Kickstarter，trying to raise  AU100，000．Butthey'veonlyraised AU3，675 so far，although they still have 37 days to go，so it's still hopeful And even if this fails，they may still find a way to get it to market．

32．What's the least possible benefit of using the Airport Jacket？D
A．it may cut down on the luggage fees．
B．it may decrease the risk of losing luggage．
C．it may save the time of passing long queues．
D．it can guarantee you a comfortable flight service．
33．What does the paragraph 3 mainly discuss about？C
A．how much luggage the couple carried
B．how luckily the couple avoided overcharging
C．how the designers got their inspiration
D．how painful the couple's flying experience was
34．What can we infer from this passage？B
A．The pockets of the'Airport Jacket have 28 in total．
B．Not all regard the Airport Jacket as a perfect invention．
C．Crowdfunding is the best way to collect money you need．
D．Airports now begin to limit the number of economy travelers．
35．What will the author probably mention in the next paragraph？B
A．Their kinds of anxiety and fear facing failure．
B．Their possible measures to market their product．
C．Their sharp and powerful attack against those opposed．
D．Their attempts to improve and enlarge the production capacity．
