21、Microplastics, the kind of current working definition, is plastic less than five millimeters. So people commonly equate that to something like a grain of rice or a sesame (芝麻籽) seed and down in terms of size class. I will say that most of the microplastics that people are interacting with are quite a bit smaller than the sesame seed size, which I think always kind of shocks people when we start talking about the numbers because they kind of can’t see a lot of these things, at least with the naked eyes.
Kieran Cox is a PhD candidate in marine biology at the University of Victoria and one of the authors of the study, which is in the journal Environmental Science & Technology. For their study, Cox and his team pulled together past scientific literature that calculated the number of microplastics in things we commonly consume, such as in tap and bottled water, sugars, seafood—even in the air that we breathe. This analysis helped them figure out the baseline amount of microplastics that people are consuming every year. They couldn’t include common foods like beef, vegetables and dairy in their analysis because data on them doesn’t exist yet. In fact, their study could account for only 15 percent of people’s caloric intake. Even missing the majority of what people swallow, the research revealed that—at the very least—humans appear to consume somewhere between 74 000 and 121 000 microplastic particles every year. That number goes up for people drinking bottled water rather than tap water.
Now, is all the plastic safe to take in? Scientists simply don’t know yet. “This is kind of the first estimate of dose (剂量), you could say, right? So if you’re thinking in terms of toxicology (毒理学) and ecotoxicology, dose is a very important factor to think about, and so this kind of presents the first estimate, but it is very much an underestimate because of what we don’t know.”

22、A new study published in Thursday’s edition of Cell reports that mosquitoes’ sense of smell is more complex than we once thought. And it may explain how they are so good at seeking us out in the darkness and lead to new strategies to fight against the potentially deadly diseases caused by their bites.
Until Meg Younger, co-author of the study, and her colleagues started studying mosquitoes, it’s long been known that mosquitoes rely on multiple clues to target humans, First, they will sense the CO2 in the breath from a distance that can be more than 30 feet. After the CO2, then they begin to sense human body smells. They follow the odors(气味) and, when they get very close, start to detect body heat. Once they land on the skin, they look for a place to bite with their legs.
In many parts of the world, their bites may lead to such diseases as dengue, Zika, chikungunya and malaria. The latter disease alone causes over half a million deaths each year around the globe.
“But most of what we know about mosquitoes’ sense of smell comes from the study of the brains of mice and fruit flies, where the pathways between the brain and smell detectors are fairly simple: Each neuron(神经元) in their smell detectors just responds to a single kind of smell and all the neurons for that smell are connected to the same part of their brains. Of course, there are countless different detectors responding to countless smells,” says Younger. “When we started looking inside mosquito brains, we found that each neuron can detect multiple smells.”
“It’s a great breakthrough,” says Josefina del Marmol, a scientist at the Harvard Medical School who wasn’t involved with the research. “It will change a lot about what we know of how mosquitoes interact with the world and give researchers additional ways to fight the bugs. But there’s more work to be done to test, neuron by neuron, which neuron actually responds to which human body smells.”
【1】What can be learned about mosquitoes from paragraph 2?
A.They look for a place to bite with their eyes.
B.They can only detect humans within 30 feet.

C.Dengue.
D.Chikungunya.
【3】What is Meg Younger’s new discovery?

B.A neuron in mosquitoes’ detectors can detect many smells.
C.All the neurons for a smell are connected to the same part of the brain.
D.The neurons in fruit flies’ brains just respond to a single kind of smell.
【4】What does Josefina del Marmol say about the new study?
A.The process is not very complete.
B.The conclusion is not very reliable.
C.More specific tests have to be done.
D.The research method is too complex.
23、For as long as they can remember Jynne Martin and April Surgent had both dreamed of going to Antarctica.This winter,they each made it to the icy continent as guests of the National Science Foundation(NSF).Bm they didn’t go as scientists.Martin is a poet and Surgent is an artist.They went to Antarctica as participants.in the NSF’s Artists and Writers program.The NSF is thegovernment agency that funds scientific research in Antarctica.But it also makes it possible for artists,including filmmakers and musicians,to experience Antarctica and contribute their own points of view to our understanding of the continent.
The mixing of science and art in Antarctica isn’t new.Some of the earliest explorersbrought along painters and photographers.Edward Wilson was a British painter,doctor,and bird expert who journeyed with RobertFalcon Soott on two separate Antamtic expeditionsmore than 100 years ago.Herbert Ponting was a photographer who also accompanied Scott on one of those expeditions.In hundreds of photos,Pontingcaptured the beauty of the continentand recorded the daily lives and heroic struggles of the explorers.
Today’s scientists write articles forscientificjournals.Unlike theearly explorers’journals,scientific papers can now be very difficult for non-scientists to understand.Writers in Antarctica workto explain the research to the public.Peter Rejcek is editor,writer,and photographer for the Antarctic Sun,an onlinemagazine devoted to news about the U.S.Antarctic Program.Rejeck began his career in the Antarctic in 2003 by spending a year at the South Pole.He has returned everyyear since,interviewing,scientists about research at Palmer,McMurdo,and South Pole stations.
There are also scientists in Antarctica who work hardto explain their research to the public.Scientist Diane McKnight wrote The Lost Seal,a children’s book that explains the research she and others are doing in an unusual ice-free area in Antarctica called the Dry Valleys.
Antarctica is full of stories and wonders that are scientific,historic.and personal. People such as Martin,Surgent,Rejcek,and McKnight are devoted to bringing those storiesto asmany peopleare they can.“Some people are going to be scientists,some people are goingto be journalists,some people are going to be artists,but we can all work together,’saysSurgent,“tocelebrate,thisextraordinary place.”
【1】What do we know about the NSF?
A.It is a government agency.
B.It only funds scientists in Antarctica.
C.It encourages the understanding of human nature.
D.It enables the mixing of science and art for the first time.
【2】Why didn’t some earliest explorers bring writers along?
A.Writers were not funded at that time.
B.Writing can’t capture the beauty of the continent.
C.Writers were not interested in popularizing science.
D.Early explorers’journals can be easily understood by the public.
【3】By mentioning Diane McKnight,the author may try to suggest that_____.
A.scientists should explain their research to children
B.writers are not necessary since scientists can tell stories as well
C.telling stories to children is more important than knowing the truth
D.no matter what role we play,we can work together to appreciate Antarctica
【4】What would be the best title for this article?
A.Antarctica:A Land for All
B.The NSF:A Program for All
C.Antarctica:A Land of Beauty and Stories
D.The NSF:A Program for Artists and Scientists
24、From the very beginning of school we make books and reading a constant source of possible failure and public humiliation. When children are little we make them read aloud, before the teacher and other children, so that we can be sure they “know” all the words they are reading. This means that when they don't know a word, they are going to make a mistake, right in front of everyone. After having taught fifth-grade classes for four years, I decided to try at all costs to rid them of their fear and dislike of books, and to get them to read oftener and more adventurously.
One day soon after school had started, I said to them, “Now I’m going to say something about reading that you have probably never heard a teacher say before. I would like you to read a lot of books this year, but I want you to read them only for pleasure. I am not going to ask you questions to find out whether you understand the books or not. If you understand enough of a book to enjoy it and want to go on reading it, that’s enough for me. Also I’m not going to ask you what words mean.”
The children sat stunned and silent. Was this a teacher talking? One girl, who had just come to us from a school where she had had a very hard time, looked at me steadily for a long time after I had finished. Then, still looking at me, she said slowly and seriously, “Mr Holt, do you really mean that?” I said just as seriously, “I mean every word of it.”
During the spring she really astonished me. One day, she was reading at her desk. From a glimpse of the illustrations I thought I knew what the book was. I said to myself, “It can’t be.” and went to take a closer look. Sure enough, she was reading Moby Dick, in edition with woodcuts. I said, “Don’t you find parts of it rather heavy going?” She answered, “Oh, sure, but I just skip over those parts and go on to the next good part.”
This is exactly what reading should be and in school so seldom is, an exciting, joyous adventure. Find something, dive into it, take the good parts, skip the bad parts, get what you can out of it, go on to something else. How different is our mean-spirited, picky insistence that every child get every last little scrap of “understanding” that can be dug out of a book!
