题目内容

4．The possibility of a murder _____，the police have set about looking for the clues to her suicide．（　　）

	A．	to be excluded		B．	to exclude
	C．	having excluded		D．	having been excluded

分析既然谋杀的可能性已经被排除，警察开始着手寻找她自杀的线索．

解答答案：D 题干中有逗号分隔，没有连词，要用非谓语动词；possibility与exclude构成动宾关系，要用过去分词表示被动；句意表达的exclude动作发生在set about之前，要用分词的完成式．故选D．

点评独立主格结构由两部分组成，前一部分是名词或者代词，后一部分是非谓语动词（不定式、现在分词、过去分词）或形容词、副词、名词或介词短语．独立主格结构本身不是句子，在句子中作状语，表时间、原因、条件、伴随、目的及状态等．

13．Traffic jams cost average Beijinger $1，126annually
By Meng Jing （chinadaily．com．cn）
Beijingers（北京人） lost as much as 7，972Yuan on average to traffic jams last year，the highest in the country，said a report．
Published by Didi Kuaidi，China's largest ride-hailing application and its partners，the report revealed Beijingers on average spent 52minutes travelling 19.2kilometers daily between their home and office．
White-collar workers in China's mega cities-Beijing，Guangzhou，Shenzhen and Shanghai-were those who lost most money to congestion．
The cost ranged between 7，972yuan and 6，324yuan per person in the four cities whose residents are among the best paid employees in China．
Research based on data collected on Didi Kuaidi's online platform showed that not only those in mega cities suffered from poor traffic conditions．
The report said residents in second-tier cities spent 37minutes on average between home and work with a travelling speed of 23km/h due to congestion．The speed was even slower than first-tier cities'24km/h．
So，B  For instance，the Fourth Ring Road in Beijing in a morning rush hour．City authorities are working on solutions to ease the pressures on traffic in the city．
21．According to the passage，People live in Beijing usually lost aboutA Yuan each month．
A.664.3           B.7，972        C.22.14           D.1，126
22．What is cause the congestion based on the text？D
A．Car numebers is increasing．
B．Too many people live in the city．
C．Drivers don't obey the laws．
D．Poor traffic conditions．
23．What does the underlined sentence"mega"means？A．
A．big               B．develop        C．beautiful         D．livable
24．At last paragraph，which sentences can be written in the black？B
A．How to ease the pressure in the road？
B．People try their best to desrease the pressures on traffic．
C．The Fourth Ring Road in Beijing is crowed．
D．Citizens lost most money to congestion．

2．A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly．The mechanical fly has become a platform for a series of new high-tech integrated systems．Designed to do what a fly does naturally，the tiny machine is the size of a fat housefly．Its mini wings allow it to stay in the air and perform controlled flight tasks．
"It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components （元件），"said Robert Wood，the Harvard engineering professor who has been working on the robotic fly project for over a decade．A few years ago，his team got the go-ahead to start piecing together the components．"The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own，"he said．
They engineered a series of systems to start and drive the robotic fly．"The seemingly simple system which just moves the wings has a number of interdependencies on the individual components，each of which individually has to perform well，but then has to be matched well to everything it's connected to，"said Wood．The flight device was built into a set of power，computation，sensing and control systems．Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured．
While this first robotic flyer is linked to a small，off-board power source，the goal is eventually to equip it with a built-in power source，so that it might someday perform data-gathering work at rescue sites，in farmers'fields or on the battlefield．"Basically it should be able to take off，land and fly around，"he said．
Wood says the design offers a new way to study flight mechanics and control at insect-scale．Yet，the power，sensing and computation technologies on board could have much broader applications．"You can start thinking about using them to answer open scientific questions，you know，to study biology in ways that would be difficult with the animals，but using these robots instead，"he said．"So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis．"
72．The difficulty the team of engineers met with while making the robotic fly was thatC．
A．they had no model in their mindB．they did not have sufficient time
C．they had no ready-made componentsD．they could not assemble the components
73．It can be inferred from paragraphs 3and 4that the robotic flyB．
A．consists of a flight device and a control system
B．can just fly in limited areas at the present time
C．can collect information from many sources
D．has been put into wide application
74．Which of the following can be learned from the passage？
A．The robotic flyer is designed to learn about insects．
B．Animals are not allowed in biological experiments．
C．There used to be few ways to study how insects fly．
D．Wood's design can replace animals in some experiments．
75．Which of the following might be the best title of the passage？
A．Father of Robotic FlyB．Inspiration from Engineering Science
C．Robotic Fly Imitates Real Life InsectD．Harvard Breaks Through in Insect Study．
