题目内容
Your phone ______ for several minutes now. Why don’t you answer it?
A. had rung B. rang
C. has been ringing D. was ringing
C
【解析】
试题分析:句意:你的手机已经响了几分钟了,为什么你不接呢?这里是在说这句话之前手机一直在响,表示动作从过去开始一直响到了现在,所以应该用现在完成进行时,故选C。
考点:考查动词时态的用法。
点评:本题难度适中。动词时态是高中阶段的重难点之一,高中要求掌握的时态需要考生牢记它们的用法,但是时态必须要结合一定的语境才能做出正确的判断。
即学即练:Experiments of this kind in both the U.S. and Europe well before the Second World War.
A. have conducted B. have been conducted C. had conducted D. had been conducted
解析:D。句意:“就在二战爆发前,美国和欧洲都进行过这种实验。”首先考虑语态,主语experiment与conduct构成动宾关系,谓语使用被动形式。题干中出现the second war是过去的时间点,before the second war是过去的过去,因此使用过去完成时。选D。
Whether you’re headed to another country for business or pleasure, it is likely that you need to keep in
touch with family or business partners in the United States. But if you plan to do that using your cell phone,
you could have an unwelcome surprise—U.S. cell phones don’t work abroad. U. S. companies use different
forms of technology, not like most of the international community, including Europe.
However, there is an easy, cost-effective solution to staying in touch while you’re traveling. You can rent a
phone that is guaranteed to work in the countries you’re traveling. Roadpost offers a 30-day cell phone rental
plan that includes free incoming calls, free voicemail and call waiting services.

arrive on the date you want. If an unexpected business trip comes up, Roadpost can provide next - day delivery
for most cities. In addition to the phone, Roadpost provides a spare battery, travel charger and a leather carrying case.
When your phone is shipped from Roadpost, you receive an e-mail confirmation that contains your international cell phone number so you can leave it with family members and business partners; Roadpost even
provides business cards preprinted with your international phone number.

to stay in touch by e-mail when traveling. With an international BlackBerry, you can email as much as you like, without worrying about an expensive bill. If you’re traveling to very remote areas, you may want to consider
renting a satellite phone: Because they Receive their signals from satellites, these phones work anywhere on the

Which are you more likely to have with you at any given moment-your cell phone or your wallet? Soon you may be able to throw your wallet away and pay for things with a quick wave of your smart phone over an electronic scanner.
In January, Starbucks announced that customers could start using their phones to buy coffee in 6,800 of its stores. This is the first pay-by-phone practice in the U.S., but we’re likely to see more wireless payment alternatives as something called near field communication (NFC) gets into America’s consumer electronics. Last December, some new smart phones which contain an NFC chip were introduced to the public.
Already in use in parts of Asia and Europe, NFC allows shoppers to wave their phones a few inches above a payment terminal – a contact- free system built for speed and convenience. But before NFC becomes widely adopted in the U.S., a few problems need to be worked out, like who will get to collect the profitable transaction(交易)fees. Although some credit card providers have been experimenting with wave-and- pay systems that use NFC-enabled credit cards, cell phone service providers may try to muscle their way into the point-of-sale(POS)market. Three big cell phone service providers have formed a joint venture(合资企业)that will go into operation over the next 15 months. Its goal is “to lead the U.S. payments industry from cards to mobile phone.”
The other big NFC issue, apart from how payments will be processed, is security. For instance, what’s to stop a thief from digitally pick-pocketing you? “We’re still not at the point where an attacker can just brush against you in a crowd and steal all the money out of your phone,” says Jimmy Shah. A mobile- security researcher, “Users may also be able to set transaction limits, perhaps requiring a password to be entered for larger purchases.”
Still uneasy about this digital-wallet business? Keep in mind that if you lose your smart phone, it can be located on a map and remotely disabled. Plus, your phone can be password protected. Your wallet isn’t.

Third-generation mobile phones, known as 3G, are the next big step for the telecom industry. Data speed in 3G networks is much quicker than that in present technology. This means users can have high-speed Internet access and enjoy video and CD-quality music on their phones.
“Mobile data is not a dream; it’s not an option but a requirement,” said Len Lauer, head of a US communications company, Sprint PCS, at a 3G conference in Bangkok earlier this month.
With 3G, you can forget about text messages telling you yesterday’s news; a 3G phone can receive video news programs, updated four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home.
Face-to-face video calls
Don’t worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset.
However, the most impressive part of 3G technology is video calling. With live two-way video communication, you can have face-to-face talks with friends and family on your mobile phone.
Many European countries have already launched the service. In May 2000 the US Government issued five license to run 3G wireless services, while the first 3G phones arrived in Italy in March this year.
International telecom companies can’t wait to sell 3G in China, the world’s largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops.
“We need to create a pool of 3G customers before the large-scale commercial launch of the service,” said Fan Yunjun, marketing manager for Beijing Mobile. “We expect that the 3G licenses will be issued late next year.”
