6．Flies are buzzing．Most people think they are dirty and annoying．But in Bryan Lessard's eyes，flies are beautiful insects with great abilities．
Lessard is a researcher at Australia's CSIRO．He is an expert on flies．According to Lessard，more than 159，000 types of flies have been found around the world．The number forms 10-15 percent of all the known animals on Earth!
Shocked？The truth is that you can never get away from flies，Lessard says．If you are a chocolate lover，you really should thank flies．Because there would be no chocolate without them!
A tiny kind of fly is the only known pollinator （授粉者） of the flower of the cocoa plant．These special flies are native to countries that are rich in cocoa，such as Brazil and Ecuador．They play a great role in the world's big sales of chocolates．Flies，as well as some other insects，also pollinate Australia's tea trees．Flies are a huge driver of the economy，but we take them for granted．
Flies can also be useful in other cool ways．Take black soldier flies for example．Scientists in Australia，India and US are turning black soldier fly larvae （幼蟲） into a nutritious feed for livestock（家畜）．The larvae are 45 percent protein．They find that chickens fed on the larvae grow larger，and don't experience any harmful side effects．As well as that，Chinese researchers from Wuhan's Huazhong Agricultural University have made oil from the black soldier fly larvae and turned the liquid into a form of biodiesel （生物柴油）．So someday our cars could be powered by flies!

32．According to Lessard，fliesA．
A．are useful to humans
B．are buzzing insects
C．love to eat chocolate
D．are the largest insect group
33．Why should chocolate lovers thank flies？B
A．They protect cocoa plants．
B．They pollinate cocoa plants．
C．They protect tea trees．
D．They pollinate tea trees．
34．Who made biodiesel from black soldier fly larvae？D
A．Scientists from Australia．
B．Scientists from India．
C．Scientists from US．
D．Scientists from China．
35．Scientists found that black soldier fly larvaeA．
A．can be a great feed for livestock．

7．Cyclist Alain Such has been dropped from the Ingotel cycling team for two years after a positive drug test at the Institute of drug Free Sport．"I was flabbergasted．"Said Didier Garcia，from Team Ingotel．"Alain joined our team last month and we had no idea that he was being examined．"
It's a story that has become more and more familiar in recent years．Dr．Mohammad Farnood，a leading sports scientist from Cairo，Egypt，said，"It is thought that some athletes will look for other ways to improve performance in addition to using drugs．"
However，it has not always been against the law．In the Olympics in 1904，Thomas Hicks won the marathon after using drugs in the middle of the race．In fact，the first one didn't make him feel better for long，so he was given another and，as a result，he fell down soon after finishing and knew nothing．Another one may well have killed him．
Things are very different today．Some scientists are considering the possibilities of using genetic engineering to further develop athletes'abilities．"If it works with no risk of discovering，"said Dr Farnood，"then it's likely to become common practice for athletes．"
Researchers are looking at the possibility of identifying"athletic"genes and correcting weak ones．Put into practice，this would make a person healthier and stronger．Once scientists understand what genes of top athletes look like，it might even become possible to identify"athletic"genes in young people，and then money could be spent on children who have the most promising genes．
"People are beginning to recognize that genetics can in many ways do good to our society，for example in saving lives and in creating better quality food for people．"Dr Farnood says．"So，is it fair to use genetic engineering in sport？You could ask if it's fair for some runners to use the latest scientifically developed footwear．The key question is whether it's available to everyone．"

32．What does the underlined word"flabbergasted"in Paragraph 1 mean？D
A．Shy．B．Proud．C．Excited．D．Surprised．
33．What happened to Thomas Hicks in 1904？C
A．He was badly hurt in training．
B．He broke the law when running in a race．
C．He took drugs and almost got killed．
D．He lost the match in the Olympic Games．
34．Who may show the greatest concern about using genetic engineering in sport？D
A．Didier Garcia．
B．Thomas Hicks．
C．Cyclist Alain Such．
D．Dr Mohammad Farnood．
35．What can we learn from Paragraph 5and 6？B
A．The possibility of identifying"athletic"genes has become available．
B．It's not clear whether it is fair to use genetic engineering in sport．
C．The practice of using drugs in sport has a long history．
D．It's dangerous to use drugs in sport．
