18．Traditional surgical procedures require surgeons to make large incisions（伤口） in a patient's body in order to gain access to the internal organs．It was once common for heart surgeons，who perform highly specialized and complex procedures，to make long incisions in a patient's chest and then split the breastbone to reach the heart．Patients who undergo surgery are often at the risk of infection，as bacteria can infect the cut in the skin．In addition，there is often a lengthy recovery period．
A surgical technique known as"keyhole surgery"has become more common in recent years．In general，the surgeon will make a couple of small incisions around the area where the operation is going to be performed．Tubes are pushed into the holes，and a tiny camera，which is called an endoscope，is put into the body．The camera is attached to a large monitor screen that is positioned so that the doctor can see it while he performs the operation．In addition to the camera，doctors also push their tiny surgical instruments through the tubes．The awkward part of keyhole surgery is that it is counterintuitive； that is to say，if a surgeon wants to move the tool to the left，he or she must push it to the right．
Other advancements in technology are also being used today in the OR （operation room）．A new machine called the"da Vinci Surgical System"has been tested in hospitals in the U．S..Unlike keyhole surgery，the da Vinci's robot's moving parts are designed to imitate the natural hand and wrist movement of a surgeon，thus providing better control and sensitivity．The system is controlled by a surgeon from a console（控制台）．Sitting at a console a few feet from the patient，the surgeon can perform an operation by holding and moving highly sensitive pads that enable him or her to control the instruments．The area of the body on which the surgeon is working is enlarged on a screen，which is attached to the console．This gives surgeons a realistic three-dimensional view of the area-similar to what they would see during a traditional surgical procedure．
Although the da Vinci Surgical System is undergoing some trials for some procedures，it has been welcomed as revolutionary by many surgeons．Patients with serious illnesses must still undergo major surgery，but the smaller incisions and less invasive procedures typically mean that a shorter recovery time is needed．In some cases，the patient's stay in the hospital has been cut in half when the da Vinci Surgical System was used．On the downside，some operations have taken up to fifty minutes longer because surgeons are inexperienced at using the new technology．As surgeons become more familiar with the machines，the time needed for surgical procedures is likely to decrease．

72．What can be learned about the traditional surgery according to the passage？B
A．The cost of the traditional surgery is very high．
B．It often leaves a large wound in a person's body．
C．Long incisions are made in a patient's chest．
D．The incision is often infected after the operation．
73．Which of the following is one DISADVANTAGE of keyhole surgery？C
A．It requires the use of long，thin tools and a tiny camera．
B．The doctor can not view the inside of the patient's body clearly．
C．The direction in which a doctor moves the surgical tools is reversed．
D．An endoscope has to be inserted into the patient's body in advance．
74．The da Vinci Surgical System differs from keyhole surgery in thatC．
A．requires that a surgeon make more small incisions on a patient
B．reduces the amount of time it takes to perform a surgical procedure
C．allows the surgeon to use the surgical instruments more sensitively
D．eliminates the need for surgeons to make large incisions on patients
75．The passage mainly tells the readerD．
A．the challenges brought about by new technology
B．the benefits and drawbacks of the da Vinci Surgical System
C．the reflections on the development in medical science
D．the application of new technologies in modern surgery．
5．They may be just passing your office，computer bag slung （悬挂） over one shoulder．Or they may be sitting in a car outside it，causally tapping away at a laptop．They look like innocent passers-by．In fact，they are stealing your corporate secrets．
Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them．A recent study in the UK，sponsored by RSA Data Security，found that two-thirds of organizations with wireless networks were risking their data in this way．Security experts patrolled （巡逻） several streets in the City of London seeking evidence of wireless networks in operation．
Of 124 that they identified，83 were sending data without encrypting（加密） them．Such data could readily be picked up by a passer-by armed only with a portable computer，a wireless modem and a few pieces of software that can be freely downloaded from the Internet．
The data could include sensitive company documents containing valuable information．Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users．
Most companies using wireless networking technology do not take even the simplest of measures to protect their data．Nearly all wireless network technology comes with some basic security features that need only to be activated （激活） in order to give a minimum level of security，for example，by encrypting the data being passed over the network．
Raymon Kruck，business development manager at Check Point Software，a security technology specialist，believes this could be partly a psychological problem．People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls．
Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in．Switching on the security that comes with the network technology should be automatic．Then there are other basic steps a company can take，says Mr．Kruck，such as changing the passwords on the network from the default （默认） setting．
Companies can also install firewalls，which form a barrier between the internal network and the public Internet．They should also check their computer records regularly to spot any abnormal activity，which might betray the presence of a hacker．
41．According to the study sponsored by RSA Data Security，two thirds of the subjectsC．
A．had most of their company data stolen   
B．depended on wireless computer networks
C．were exposed to drive-by hacking       
D．were unaware of the risk of wireless hacking
42．Whichof the following is NOT considered in the study？A

44．Raymond Kruck most probably agrees that wireless network security involvesB
A．wireless signal administration  
B．changes in user's awareness
C．users'psychological health     
D．stronger physical walls
45．The passage is lost likely to be seen in aD
A．book review    B．science fiction   C．textbook   D．computer magazine．
15．Whenever I see anyone buying a National Lottery ticket，I want to stop them and ask if they know just where their money is going．
The lottery money is supposed to go to charity，but it makes me angry to see some of the so-called"good causes"that it's being used to support．Also，Camelot，the organizers，have made a profit of￡10.8million in five months．We hear that a lot of that money is boosting（increasing） the pay packets of the company's bosses．
For the past 10years I've been helping to raise funds for a cancer research charity called Tenovus．My husband，Sandy，died from cancer 11years ago when he was only 51．There's been a long line of deaths in our family through cancer and it's been destructive．I've also lost two sisters-in-law，my brother，Michael，my father-in-law and my father．That's apart from several close friends
The charity is 50years old now and raises money mainly for breast cancer research．It also runs a support line for the families of cancer sufferers．Our local group raises￡3million and half that money came from sales of our own lottery tickets at supermarkets．But our income has dropped by half since the National Lottery was introduced．
I'm not against people playing the National Lottery，but they should think about what they're doing．The chances of winning the cumulative amount of money are so small； they might as well throw their money away．The Government tells us that the proceeds （收益）are going to things like the arts and sports，but what about the National Health Service？They should give some cash to that，too．How can they justify spending ridiculous amounts of cash on so-called works of art like display of potatoes or buying up Winston Churchill's papers at a cost of￡12million？
So who really are the winners in the National Lottery？When I think of all that money people could be donating to cancer research，I could weep．It's time people realized how charities across the country are suffering because of the National Lottery．It's disappointing and so frustrating．

66．The reason why the writer raises funds for cancer research is thatC．
A．she herself is suffering from cancer    
B．the cancer is the most frightening disease
C．a number of her relatives died of cancer
D．some cancer research needs more money that other research
67．In this text the writer is expressingA．
A．her personal opinions               
B．the opinions of the general sufferers
C．her feelings about cancer sufferers     
D．some ideas of fund-raising
68．The organization"Tenovus"isB．
A．run by a group of people in the writer's town
B．a charity organization which has some local groups
C．set up to collect money for people who lose their relatives
D．set up to assist the National Lottery
69．The writer seems to hope thatC．
A．people will spend more money on the National Lottery
B．people will give more money to charity
C．most of the lottery money will go to charity
D．most of the lottery money will be used for cancer research
70．What's the writer's attitude toward the National Lottery？B
A．The writer is enthusiastically supporting the National Lottery．
B．The writer has objections to the National Lottery．
C．The writer believes that the lottery money should be used for cancer research．
D．The writer is just expressing her feelings about collecting money for charity．
2．People in the United States honor their parents with two special days：Mother's Day，on the second Sunday in May，and Father's Day，on the third Sunday in June．
Mother's Day was proclaimed a day for national observance by President Woodrow Wilson in 1915．Ann Jarvis from Grafton，West Virginia，had started the idea to have a day to honor mothers．She was the one who chose the second Sunday in May and also began the custom of wearing a carnation．
In 1909，Mrs．Dodd from Spokane，Washington，thought of the idea of a day to honor fathers．She wanted to honor her own father，William Smart．After her mother died，he had the responsibility of raising a family of five sons and a daughter．In 1910，the first Father's Day was observed in Spokane．Senator Margaret Chase Smith helped to established Father's Day as a national commemorative day，in 1972．

19．Tanzania Tarangire is a national Park which lies in Tanzania．The park itself covers an area of around 2，850square kilometers，making it the sixth largest park of its kind in the country．I recently visited Tarangire to see what it was like…．
One of the first sightings upon entering the park which I found was a huge herd（群）of elephants．Our guide told us that Tagrangire was probably the best place in Tanzania to find large herds of elephants，and that their population in the park was around 2，500．We continued to watch the elephants as they stood under trees and scratched themselves against the trees to hit the spot of an itch（痒处）．
To the right of the elephant herd，we noticed a big tree!Our guide informed us that this was a Baobab tree and that they could live for hundreds of years．Compared with this tree，the elephant just looked like dwarfs（侏儒）!We were informed that Tarangire was one of the best National Parks in Africa to see so many Baobab trees．
As we continued our drive through the park，we finally reached a watering hole．Our guide warned us that there were lions all around us．It took us all a while to find them，but there they were!Most of them are resting in the shade under brushes，but there was one that was drinking from the watering hole directly in front of us．We then noticed just to our right，there were a couple of fresh zebra corpses（尸体）-it seemed as if the lions which were resting had killed them!We were unlucky not to have seen the actual kill，as our guide had mentioned that the zebra corpses were fresh and the kill had occurred within the last hour．
Our final big sighting was one that none of us were expecting to see，even our guide!We pulled over to where there was a large gathering of cars，with a sleeping leopard（美洲豹）there!We took photos happily and excitedly and observed its surprising body before returning to our hotel as it was getting late．
So，I hope you enjoyed my description of Tarangire，and that I have inspired you to add this amazing park to your very own Tanzania travel route．
