14．In 1885，a young doctor named Conan Doyle opened offices in London．He wanted to be a successful doctor，but for some reasons he never found enough patients．To pass the time，be began to write stories and send them to the newspapers．
Conan Doyle's stories were about a clever detective，Sherlock Holmes．Conan Doyle wrote that Sherlock Holmes lived in Baker Street in London，and people with problems came to Sherlock Holmes with their problems，too．He was able to solve mysteries that the cleverest policemen in England were unable to figure out．Sometimes Sherlock Holmes could solve a mystery without leaving his chair．He listened carefully to the information his client（委托人） gave and figured out the answer．At other times he spent days or weeks looking for clues．Sherlock Holmes traveled to different cities and countries to solve the mysteries．Sometimes he wore disguises，pretending to be an old man，or a sailor．Holmes did anything to find out the answer to the mysteries he was working on．His best friend Dr．Watson kept him company（陪伴）on most of his adventures．
Sherlock Holmes is the most famous detective in English literature，but many people don't understand that he is a fictional character，not a real person．The English post offices report that people still send mail to Sherlock Holmes in Baker Street．Even he gets more than 2，000letters every year．

11．I don't feel liketaking （take） a nap at the moment．

18．The parents felt guiltyabout not being able to send their son abroad for further study．

8．Scientists fear rising energy bills may lead to an increase in obesity （肥胖） after discovering a link between poorly-heated homes and higher body-fat．
Researchers from the University of Stirling's Behavioural Science Centre set out to explore claims that warm indoor temperatures have contributed to rising obesity levels in winter．Instead，the team found that people who live in well-heated homes are more likely to have low body mass index （体重指数） levels while those who keep their heating turned down or off tend to be heavier．
Dr Michael Daly，behavioral scientist and senior lecturer，said："We set out to investigate the scientific claims that cooler indoor temperatures help us maintain a healthy weight by pushing our bodies to use up more energy．In fact，the research suggests people may eat less and burn more energy when in a warmer indoor environment．
The 13-year study，published in the journal Obesity，involved more than 100，000adults across England．
Researchers found reduced weight levels among people living in homes heated to above 23°C（73F），which involved about 15，000of the households studied．
Dr Daly said："As national gas bills continue to rise faster than the rate of inflation，this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs．"
This is not just about people who live in well-heated homes being in the financial position to afford more expensive low-calorie foods，exercise classes and sporting activities，and therefore finding it easier to maintain a low BMI level．The study took age，sex，social class and other factors into account．
"The comfortable temperature of 20°C-23°C is where we feel comfortable in our clothes and are neither hot nor cold．At temperatures above this，we use more energy and we eat less because our appetite is affected．"

29．The findings of the research can be described asB．
A．horrible B．surprising C．funny D．encouraging
30．According to the passage，with rising gas bills，people may turn down or off their heating toC．
A．stay in shape B．maintain a low BMI level
C．save money D．avoid eating more
31．Which of the following can be the best title for the passage？A
A．Obesity links to poorly-heated homes
B．Well-heated home's contribute to obesity
C．Obesity---A weighty problem in England
D．Rising energy bills help maintain a healthy weight．

15．The mystery of why humans are the only animals to have chins may have been solved by scientists who suggest that it is connected to the invention of cooking．
A paper from the University of Florida tries to explain exactly why humans-unlike all other primates-have chins．
A team led by Dr．James Pampush collected information from more than 100kinds of primate and compared it with historical information．Computer modelling found how the chin developed．
Random genetic change was ruled out because the chin developed 77times faster than the average genetic change．And the study finds no evidence that it served a useful purpose．The research，published in the Journal of Human Evolution，suggests the chin is a by-product of another event．In this case，the event could well be the invention of cooking．
"The chin began to appear as a result of major changes six million years earlier．The arrival of cooking and softer food meant humans no longer needed big teeth and powerful jaws，and over the next two million years to 200，000years both got smaller and the chin was born，"said Dr．Pampush．"My guess is that it most likely happened around two million years ago when there was a jump in brain size．The changes which finally lead to the chin are directly related to cooking，and indirectly related to larger brains and bodies．"
Dr．Pampush's new theory goes against previous suggestions that the chin was an example of sexual selection，with attractive chins marking out men who are likely to make good mates．The fact that both men and women have chins means the theory is unlikely．
Another theory put forward in the past said that the chin was a way to balance out the stress of chewing，but Dr．Pampush also threw doubt on that idea．
32．The reason why we have chinsB．
A．is connected to humans'action of chewing
B．has something to do with cooking
C．is random genetic change
D．is related to eating time．
33．How did the researchers get their result？D
A．By carrying out experiments．
B．By studying scientific theories．
C．By examining the human brain．
D．By comparing recorded information．
34．Before developing chins，humansA．
A．had bigger teeth
B．cooked softer food
C．had smaller jaws
D．had larger bodies
35．According to Dr．Pampush，the chin most probably appeared aroundC．
A.6million years ago．
B.4million years ago
C.2million years ago
D.0.2million years ago．

12．HAVE you ever gotten a song kept in your head？You sing it all the time-on your way to school，before sleep，even when you're sitting on the toilet．You want to forget it，but the music just keeps sounding in your head．
Some people call these annoying songs"earworms"because they are just like parasites（寄生虫）-they"live"in your ears and refuse to leave even when you tell them to．
But why do some songs become earworms and not others？According to Ira Hyman，a music psychologist at Western Washington University，people are more likely to remember songs that are simple and repetitive，especially ones with that type of music．"Choruses tend to get stuck in your head because they are the bit we know best，"Hyman told The Tele-graph．
If you've got an earworm，you can suffer an attack without even hearing it．Seeing words from the song or hearing someone mention it could both cause the domino effect that starts the song running．
Scientists have been trying to find a solution to deal with earworms．They say the best way is to fill your mind with something else．But here is the tricky part：the task you do should be neither too hard nor too easy．The harder you try not to think about the music，the more you won't be able to help it．On the contrary，a task like jogging which is too easy won't keep your brain busy enough，and that could allow the song to come back．
"The key is to find something that will give the right level of challenge．"said Hymen．Reading a difficult book or a good novel could count．

21．What can we 1earn from the passage？A
A．People may sing earworms everywhere．
B．You can suffer an attack of an earworm on hearing it．
C．You can forget the melody by trying hard not to think about it．
D．Hearing someone sing the song can't start the song running in your head．
22．What kinds of songs will probably become earworms？C
A．Classical songs．
B．Songs we 1ike best．
C．Simple and repetitive songs．
D．Songs that are unfinished．
23．According to the article，if you want to get rid of earworms，you shouldC．
A．Listen to a new song

13．Each year millions of babies are born too soon and too small．Premature or preterm births mean births at less than thirty-seven weeks．
Prematurity is the leading cause of death in newborn babies．More than one-fourth of the four million newborns who die each year around the world were born too early．
Preterm babies that survive can suffer a lifetime of serious health conditions．The examples include cerebral palsy，blindness，hearing problems and learning disabilities．Families and communities face emotional，physical and financial costs．
Christopher Howson is the vice president for global programs at the March of Dimes．His group and the World Health Organization recently published a report called"The Global and Regional Toll of Preterm Birth．"
Christopher Howson："Frankly the problem of preterm birth is under-recognized and undervalued．People fail to recognize how serious the problem is．I mean，this report shows that thirteen million babies are born every year preterm，and that over a million of those babies die as a result of being born too early．"
And these are just estimates； the true numbers could be even higher．More than eighty-five percent of preterm births happen in Africa and Asia．Africa has the highest rate，with about four million cases each year．
Christopher Howson says many of the causes of preterm births are related to poverty and weak health-care systems．
Christopher Howson："For example，the poor overall health and nutritional status of women．A high burden of infectious diseases．A lack of family planning-allowing a woman to decide when to start and end having children．And also the lack of good prenatal（产前） care programs that might identify problems early on in pregnancy．"
Preterm births are a problem not just in the developing world．The combined rate in the United States and Canada is the second highest in the world．Preterm birth rates in the United States have increased thirty-six percent in the last twenty-five years．
This has been largely the result of two reasons．One is an increase in pregnancies among women over age thirty-five．The other is an increase in the use of reproductive therapies（生殖治疗）．
32．This passage is mainly aboutC．
A．the causes of people's bad health throughout the world
B．how to improve people's health throughout the world
C．premature or preterm births throughout the world
D．Christopher Howson，vice president for global programs at the March of Dimes
33．All of the following are causes of preterm births EXCEPTA．
A．too many deaths of newborn babies
B．poverty
C．Lack of family planning
D．the lack of good prenatal care programs
34．Which of the following is a TRUE statement according to the passage？B
A．Preterm birth rates in developing countries are dropping and they are increasing in some developed countries like the US and Canada．
B．The increase in pregnancies among women over age thirty-five and the increase in the use of reproductive therapies result in the increase of preterm birth rates．
C．Fortunately，many people have already realized the seriousness of the problem of preterm births．
D．Preterm births must be a problem for only poor areas because of poverty．
35．Where can we probably read this article？C
A．International news reports
B．History and political papers
C．Science magazines
D．World trade guides．
