9．Virtual （虚拟） Teams
Virtual teams are a great way to enable teamwork in situations where people are not sitting in the same office at the same time．（51）E This is particularly so for businesses that use virtual teams to build global presence，or need less common skills or knowledge from people who are unwilling to travel．
Virtual teams are governed by the same basic principles as traditional teams．（52）A It is the way the team members communicate．They rely on special communication channels enabled by modern technologies，such as emails，faxes，and teleconferences，and alike．Due to more limited communication channels，the success of virtual teams is much more sensitive to the type of project the group works on，what people are selected，and how the team is managed．
（53）B One challenging case is the projects that rely heavily on integrated work．That is to say，when each person's work depends significantly on what someone else is doing at the same moment，like in a sports team，there is an ongoing heavy exchange of information in real time，and the tasks have to go through a strict order within a short time．
Not everyone can perform well in a virtual team environment．（54）D Another important quality is communication skills．The team members must be able to communicate clearly and positively．
Managers of virtual teams need to pay much more attention to having clear goals，performance standards，and communication rules．People have various assumptions on what to expect from each other．（55）G
One of the biggest challenges of virtual teams is building trust between the team members．Trust is important for unblocking communication between members and increasing motivation of each person in the team．The issue of trust needs special attention at any stage of team existence．

A．Yet，there is one significant difference．
B．Not every type of project is suitable for a virtual team．
C．A virtual team can choose whatever project they like to work on．
D．The members must be self-motivated and able to work independently．
E．Such teams are now widely used by companies and organizations to cut business costs．
F．Members of virtual teams communicate quite well although they never meet face-to-face．
G．To avoid misunderstanding，clear rules that everyone understands and agrees on are necessary．

8．As a leading producer of greenhouse gases，China     the United States as the largest consumers of energy．（　　）

7．When I came home to London at the end of my first term at university in December 1968，I was flat broke，and more broke because it was Christmas，so I went to an employment agency for a job．
"Would you like to work for the Beatles？"they asked．
Don't you have anything better？"I asked．
Fifteen minutes later I got the job．Wen I asked why they accepted me when millions would have done the job for free，the answer was"That's just the proble．"Yes．I owed the job to the fact that I was not a crazy fan．
But of course I was a fan．It was difficult not to be．I worked over the winter holiday in 1968 and also during Easter 1969．I had to take a taxi in the days to deliver papers sealed in envelopes to the Beatles'house．I took the envelopes to the address，handed them over to whoever answered the door and lift．Who would entrust（委托）such papers to an unknown student today-the envelopes would be opened and the contents of the papers copied and sold to the Press，I t never opccurred to me to do that．Much has been lost in 40 years!
I am always asked how many autographs（签名） I collected，and the answer is none．How uncool would it have been to ask for an autograph？Far better just to hear the Beatles's greets--"Hi，boy．"How's it goping？"
More than 40 years later，this remains the best job I have ever had．It met my immediate material need and provides a memory that can be my life treasure．For a child of the 60s，this was its peak．If some details of the memory are not so fresh，it's because they weren't important then．At 19，you take man you things that happen for granted．At 61，they become gold dust．If I had known that then，I would have kept a diary．
