Bragging自吹自擂 about your
fancy new cell phone is a fleeting pleasure; after all,
today's coolest models tend to be next month's paperweights.
By contrast对比, the half-life of a
cordless phone for the home is measured in years. So if you really
want to be ahead of the tech curve, forget the cell-phone wars and
check out the new 5.8-GHz cordless phones. qIwV q!=
K,x[1]W6DiH
Named after the frequency of the radio wave (measured in billions
of cycles per second) that carries the signal between the handset
and the base station, 5.8-GHz phones promise more clarity because
there are fewer devices that operate on the same frequency and thus
fewer to cause interference干扰. If you have a cordless phone
that is a couple of years old or even a new one that costs less
than $50, chances are it is a 900-MHz model that is
highly susceptible易受影响的 to static
or buzzing from baby monitors, wireless speaker systems and
your neighbors' 900-MHz phones. The newer 2.4-GHz units, introduced
as an improvement over the 900-MHz models, do get less static, but
wireless home networks and microwave ovens can still trigger a
snap捕捉-crackle-pop
effect. Not so the 5.8 GHz. So far, only a few companies sell the
new models, and they don't come cheap. Uniden's TRU5865 costs $149,
while the Vtech 5831 is $179. I preferred the Uniden because it was
static free both inside my apartment and up to a block away. Its
compact design hides the antenna inside the handset, and the
glowing orange keys and display look sharp. The VTech got equally
clear reception indoors, but I could stray only a few buildings
down the block before buzzing set in. X7*

But is it really worth an extra $100 (or more) to step up to 5.8 GHz? Maybe. When I tried out the Panasonic KX-TC1481B, a $39 900-MHz model, I could hear other conversations and even music coming through the phone. I got much clearer reception with the Motorola MA351, a $60 2.4-GHz model--except when I turned on my microwave oven and was assaulted by weird vibrating noises coming through the handset. Still, the Motorola is a decent option体面的 at a fair price. %NHYW\sKX

No matter which kind of phone you're considering, a few other factors are worth keeping in mind. First, ask about battery life. While I liked the reception best on the Uniden, for example, it can go only four hours between charges vs. eight on the Vtech. ('o &Q_

Next, find out if the phone is analog or digital. Both 5.8-MHz phones are digital, but that's not always the case with the models that use other frequencies, and this makes them an easier target for eavesdroppers. The best digitals use digital spread-spectrum (DDS) technology, which sends the signal down a broad range of frequencies to ensure that it gets through. $G?(OWI}l`

Finally, shop at a store that offers a money-back guarantee. That way you can torture test the phone for a few days. Then, once you're certain everything's O.K., go ahead and start bragging about it to all your friends. /#q")4Mf

主体句式：chances are … ~c4Y*]J
结构分析：本句是一个条件从句。在从句中，两个that引导的都是定语从句，分别修饰phone 和a new
one，其中one指代的也是phone；主句句形是chances are，这是一个固定用法，意思是it is most
probable；主句中that引导的是定语从句，其中susceptible to的意思是“易受影响的”。 m3
5G;
句子译文：如果你家的无绳电话是你两、三年前购买的，或者是你花了不超过50美元的价格新买的，那么你这部电话很可能是900兆赫的。这款电话极易受静电的干扰，婴儿监控器、无线扬声器系统以及邻居家的900兆赫款电话都能使它发出嗡嗡声。

题目分析 q;rU}hAzG0
1. 答案为C，属事实细节题。文章开头就手机和无绳电话的实用性进行了对比，意在指出 + EM '-
无绳电话的实用性较强。 [.2>=3T
2. 答案为A，属事实细节题。原文对应信息是“While I liked the reception best on the
Uniden, for example, it can go only four hours between charges vs.
eight on the Vtech.”。选项B是这两种无线电话的共同特征；选项C和D是Uniden的特征。
/Z^+K
3.
答案为D，属猜词题。在文章第二段，作者就5,800兆赫无绳电话和以前的无绳电话产品在抗干扰性能进行了对比。5,800兆赫无绳电话几乎不受静电干扰的影响，而以前的产品则不同，由此可猜出词义。

5. 答案为C，属事实细节题。本题的关键是对句子“If you have a cordless phone that is a couple of years old or even a new one that costs less than $50, chances are it is a 900-MHz model that is highly susceptible to static or buzzing from baby monitors, wireless speaker systems and your neighbors' 900-MHz phones.”的理解。详细解释参见难句突破部分。
