閱讀理解
     It is finally possible for serious mobile communication users to invest in a service that meets their
highest expectations,thanks to the arrival of the "4G" communication on the market!But what exactly
is this all about,and what real benefits do clients stand to gain by switching to such a plan?Below we
hope to clear up precisely these concerns in a bid to bring wireless users closer to the reality that they
have always dreamt of .
     The initials "4G" stand for "fourth generation "wireless communication standards,and at present they
are the latest generation of such standards.Unlike in the past,this time the generational leap is going to
take a good long while to repeat itself,so the fourth generation users do not need to fear investing in
something that is simply going to be left by the wayside in a few short months or even weeks.That's
because this generation of wireless standards is the culmination(頂點(diǎn)) of a much broader and more
coordinated (協(xié)調(diào)的) set of developments in labs across the world,rather than the kinds of isolated
and shortsighted pushes that resulted in previous generations of wireless standards.
     The results of this internationally supported new generation of wireless Internet are much more
significant than most people would imagine,as the steps forward are much greater than the case
between previous generations of wireless systems.Whereas between 2G and 3G wireless systems
the rate of data transfer barely rose a few Kbps (千字節(jié)每秒) and was accompanied by few other
major advances.With the arrival of the latest generation the bar (緩沖地址暫存器) has been raised
several Mbps (兆比特每秒) and furthermore several other advantages have been presented.It means
that the fourth generation mobile users will be able to capture signals in a broader variety of locations
and circumstances,not being cut off simply because they have hopped from one network to the next.
     Ultimately,the fourth generation mobile Internet means a vast readjustment(再調(diào)整) in the way
people live their personal and professional lives,offering them the kind of mobility that they have always
hoped for.And as the fourth generation capabilities are spread over increasing parts of the country,
starting in the nation's largest cities and spreading out wards from there,it will in the near future be
possible to roam from coast to coast without losing one's connection for even a second.

1. What is the writer's purpose of writing this text?
A. To explain the "4G" communication systems.
B. To advertise the "4G" communication systems.
C. To show the great capacities of the "4G" systems.
D. To show his ideas about the "4G" communication.

2. From this text we can infer that ________.
A. more and more people have no interest in the "4G" communication
B. it will be difficult to surpass the "4G" communication systems at present
C. the "4G" communication will surely repeat itself in the future
D. the "4G" communication technology is the most advanced technology at present

3. Which of the following is true about the previous generations of wireless standards?
A. It took a long time to develop the previous generations.
B. The previous generations users think highly of the systems.
C. There were only few isolated and shortsighted changes in them.
D. It is difficult to imagine the future of the wireless standards.

4. What is the most significant advantage of the "4G" systems?
A. Users will be able to catch more signals from all over the world.
B. It will be much cheaper to use the "4G" communication systems.
C. It will be much faster for data to transfer with the help of the  "4G" systems.
D. Users will be able to jump from one network to another.
