　　Ⅱ.阅读理解

　　A

　　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(顶点) of a much broader and more coordinated (协调的) 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 (千字节每秒) and was accompanied by few other major advances.With the arrival of the latest generation the bar (缓冲地址暂存器) 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(再调整) 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.

　　答案：A　[推理判断题。本题考查本文的写作目的。根据首段的最后一句我们可以看出，本文写作的主要目的就是要向读者介绍4G通讯。]

　　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

　　答案：B　[推理判断题。根据整篇文章的意思可知A项明显不对；由第二段中的“Unlike in the past，this time the generational leap is going to take a good long while to repeat itself”和“That’s because this generation of wireless standards is the culmination(顶点) of a much broader and more coordinated(协调的)set of developments in labs across the world”可知C项和D项是文章已经告知的事实，而不是推断出来的结论；根据第二段的最后一句的大意“4G技术无论在广度还是在协调性方面已经达到顶点，它不再是以前的无线电标准了”可以推断出“目前它很难被超越”的结论。]

　　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.

　　答案：C　[事实细节题。根据第二段的最后一句的后半部分“rather than the kinds of isolated and short­sighted pushes that resulted in previous generations of wireless standards”可知4G以前的几代无线电标准都是在原来的基础上作了孤立的、目光短浅的改进。据此，我们可以得出本题的答案。]

　　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.

　　答案：C　[推理判断题。根据第三段的第二句和第三句我们可以知道，与2G和3G相比，4G最重要的改变是在数据传输速度方面。在以前的2代、3代通讯技术改进的过程中，只是经过了一些细小的改进，数据的传送速度也只提高了每秒几千个字节。而第4代技术则提高了每秒几个兆比特的速度。四个选项中A项内容在文章中找不到根据；B项，文章也没有从价格方面谈论4G的优势；D项具有一定的迷惑性，从第三段最后一句可知“从一个网络转到另一个网络”是4G出现的问题，故D项也不对。]

　　B

　　The influenza virus(流感病毒) or the flu is spread from person to person in the air when an infected person coughs or sneezes.There are 3 types of the flu：

　　—Type A viruses can infect people，birds，pigs，horses，seals，whales，and other animals，such as avian flu or bird flu.

　　—Type B viruses infect people and result in smaller outbreaks(爆发)．People infected with type B viruses are often hospitalized with higher death rates.

　　—Type C viruses cause mild illness in humans without the onset of an epidemic (流行病)．

　　Most people are familiar with the symptoms of the flu，but they can be mistaken for a severe cold.The flu infection is far more serious and can cause severe health complications (并发症)．There are many viral infections that can cause flu­like symptoms.It is better to visit your doctor so other possibilities can be ruled out before your obtaining treatment.

　　The flu virus attacks the body's cells and changes into different forms，which is why people who have received the flu shot (流感疫苗接种) may still get ill with the flu.The influenza virus is transmitted_ through direct contact with infected persons such as by inhaling (吸入)droplets when they have coughed or sneezed.It can also be spread by handling objects such as doorknobs and telephone receivers that an infected person has been in contact with.

　　If you have the flu，get plenty of bed rest and drink lots of fluids.Most people recover from the flu in one to two weeks.Doctors often recommend flu vaccines( 疫苗) for highrisk groups such as young children，the elderly，those with chronic(慢性的) diseases，weak immune systems，or professionals working with high­risk groups.

　　5．Which of the following is true about bird flu?

　　A．It is a disease which can spread among humans and animals.

　　B．Only animals and birds but not humans can be infected by this kind of virus.

　　C．This kind of disease can cause higher death rates among humans.

　　D．Bird flu won't cause the outbreak of an epidemic among humans.

　　答案：A　[细节理解题。由文章中的“Type A viruses can infect people，birds，pigs，horses，seals，whales，and other animals，such as avian flu or bird flu.”可知A项正确。B项与文章内容不相符；C项所讲的是“Type B viruses”引起的感冒的特点；D项内容在文章中找不到根据。故正确答案为A。]

　　6．When you cough or sneeze，a proper suggestion given by the writer is to ________.

　　A．take some medicine at once

　　B．see a doctor to make sure of the disease

　　C．drink more water

　　D．take more exercise and bed rest

　　答案：B　[细节推断题。根据第五段的内容可知，流行性感冒(the flu)往往被误认为是重感冒(cold)，因为它们有着许多相同的症状，所以在得到治疗之前最好去看医生。]

　　7．Why some people who have received flu vaccines are still down with the flu?

　　A．Because the flu is not easy to be treated.

　　B．Because the flu can spread from person to person.

　　C．Because people are easy to catch cold.

　　D．Because the flu virus may have different forms.

　　答案：D　[推理判断题。根据第六段的首句可知，即使注射了流感疫苗的人往往也还会染上流感，因为流感病毒攻击人体细胞后变成了不同的形式，有不同的变种。]

　　8．Once you are down with the flu，what should you do?

　　A．Take flu vaccines.

　　B．Improve immune systems.

　　C．Take enough bed rest.

　　D．Do more physical exercise.

　　答案：C　[细节理解题。根据本文的最后一段的首句可知，在得了流感后，应该多卧床休息，多喝流体性食物。]
