20.The Group of Eight ______ by eight of the world's wealthiest nations in 1998.(  )
A.was formedB.formsC.is formedD.formed

分析 八国集团是由八个世界最富有的国家在1998组成.

解答 答案是A.考查被动语态,分析句子可知The Group of Eight 是主语,form动词"组成"与主语形成被动关系,1998年是过去时间,所以用一般过去时的被动语态,故答案选A.

点评 被动语态由"助动词be+及物动词的过去分词"构成.被动语态的时态变化只改变be的形式,过去分词部分不变.疑问式和否定式的变化也如此.掌握各种时态的被动语态是解题的关键.

15.By 2050,a completely new type of human evolve as a result of extremely new technology,behavior,and natural selection.This is according to Cadell Last,a researcher at the Global Brain Institute,who claims mankind is undergoing a major"evolutionary transition".
In less than four decades,Mr.Last claims we will live longer,have children in old age and rely on artificial intelligence to do ordinary and boring tasks.This shift is so significant,he claims,it is comparable to the change from monkeys to apes,and apes to humans."Your 80or 100is going to be so radically different than your grandparents,"Mr.Last says,who believes we will spend much of our time living in virtual reality.Some evolutionary scientists believe this age could be as high as 120by 2050.
Mr.Last claims humans will also demonstrate delayed sexual maturation,according to a report by Christina Sterbenz in Business Insider.This refers to something known as life history theory which attempts to explain how natural selection shapes key events in a creature's life,such as reproduction.It suggests that as brain sizes increase,organisms need more energy and time to reach their full potential,and so reproduce less.
Instead of living fast and dying younger,Mr.Last believes humans will live slow and die old."Global society at the moment is a complete mess,"he told MailOnline."But in crisis there is opportunity,and in apocalypse (启示) there can be transformation.So I think the next system humanity creates will be far more sophisticated,fair,and abundant than our current civilization."
"I think our next system will be as different from the modern world,as our contemporary world is from the medieval (中世纪的) world.The biological clock isn't going to be around forever,"he added,and said that people could pause it for some time using future technology.
The change is already happening.Today,the average age at which a woman in Britain has her first baby has been rising steadily stands at 29.8.In the US,just one percent of first children were born to women over the age of 35in 1970.By 2012,that figure rose to 15percent.
"As countries become socio-economically advanced,more and more people,especially women have the option to engage in cultural reproduction,"Mr.Last added.And as well as having more child-free years to enjoy leisure time,he believes artificial intelligence will make up the need for low-skill jobs.We may also spend a large amount of time living in virtual reality."I'm not quite sure most people have really absorbed the implications of this possibility,"Mr.Last said.
His views are detailed in a paper,titled"Human Evolution,Life History Theory,and the End of Biological Reproduction"published Current Aging Science.

10.Cellphone feels like a part of your body?Calling mobile phones the"remote control"for life,market research firm Synovate's poll(民意调查) said cell phones are so ubiquitous that by last year more humans owned one than did not.Three-quarters of the more than 8,000 respondents(受访者) polled online in 11 countries and regions said they take their phone(s) with them everywhere,with Russians and Singaporeans the most attached.More than a third also said they couldn't live without their phone(s),topped by Taiwanese and again Singaporeans,while one in four would find it harder to replace the mobile than their purse.Some two-thirds of respondents go to bed with their phones nearby and can't switch them off,even though they want to,because they're afraid they'll miss something.
"Mobiles give us safety,security and instant access to information.They are the number one tool of communication for us,"Jenny Chang,Synovate's managing director in Taiwan,said in a statement.
Mobiles have also changed the nature of relationships,with the survey finding nearly half of all respondents use text messages to communicate.Apart from the obvious calling and texting,the top three features people use regularly on their mobile phones globally are the alarm clock,the camera and the games.As for email and Internet access,17 percent of respondents said they checked their inboxes or surfed the Web off their phones,led by those in the United States and Britain.
"As the mobile becomes more and more an all-in-one(一体化) device,many other businesses are facing challenging times.The opportunities for mobile manufacturers and networks however are enormous,"said Synovate's global head of media,Steve Garton.
