For recreation league athletes，there’s nothing worse than when one of your teammates
drops out at the last minute.When a recreation league ice hockey(冰上曲棍球) team in Edmonton
needed a goalie(守门员)，they got a save from an unlikely hero.
Nelson Rego，who is 100% blind，plays blind ice hockey for the Edmonton “SeeHawks”
and accidentally met another goalie，John Hunter，who was inquiring online about a chest
protector.Later Hunter got injured，and trying to help his team find a goalie for a league game，he
reached out on the Edmonton Goalies Facebook page.
“Nelson calls me，and he starts out with，‘Hey，how’s the chest protector going？’”
Hunter later shared about the remarkable story.“Then Nelson continues，‘By the way，I’m
not sure if this is a good idea but I’ve learned that you’re looking for a goalie substitute for your
league game tonight.What do you think about me playing？’”
The team was “all in”，so Rego got ready for his first-ever sighted league match.
According to the players，they didn’t tell the referee until the puck(冰球) drop that their
goalie was blind—information with which he didn’t really know what to do.
In an interview with CTV Edmonton，Rego explains he keeps himself centered in the goal
by measuring the distance between the posts with his stick and his glove.After he uses sound to key
into where the puck is and if it’s being challenged，all the while he follows verbal instructions
from his loving wife Emelinda，in the stands telling the action.
The game was by no means a washout for Rego，because even though Rego’s team lost，
he hung in there and earned the respect and admiration of the team.
This remarkable night is just one step in Rego’s hockey career and he wants to go
further.Rego says，“If it’s something you want to do，just do it.It’s amazing to watch
hockey，but it’s even better to play it.”

Studying the DNA of 300 mice has flagged up(引起对……的关注) genes which have been
linked to hereditary(遗传的) sight loss for the first time.Researchers say because mice’s genes are
so similar to humans’，their findings could lead to the treatment of more genetic diseases.
Scientists at the University of California，Davis studied information from a data bank of
mice’s genetic material.They found 347 genes linked to eye problems，with just 86 of them
having been studied in the past.
Only around 50 to 75 percent of hereditary eye diseases in human can be explained with
present science.The researchers believe these hundreds of new genes found in mice could be a key
to explaining—and therefore being able to treat the other 25－50 percent.
“This is extremely valuable for people with hereditary eye disease，” said researcher
Professor Ala Moshiri.“All researchers are going to start using these data.In the past，we knew
the problem was there but we didn’t know where to look.Now eye centers can call back patients
and screen them for these new genes.We expected that more and more of these genetic diseases will
be treatable.” Also，the fact is that more than 60 percent of eye problems at birth are ones
resulting from the baby’s parents!
Thanks to data from the International Mouse Phenotyping Consortium(IMPC)，which is
trying to work out what every single gene in a mouse is responsible for，with the aim of translating
it to humans，scientists are moving closer to figuring out all genetic causes of blindness.To do
this，scientists separate a single gene from other ones at a time and then observe what effect it has
on the mouse for a long time.This has so far been done more than 7,000 times and has achieved
great success.Researchers are now working alongside eye care centers in Texas and Iowa in order
to compare the mice’s genes to those of patients.
5．How many hereditary-sight-loss-related genes were newly found?
A．86. B．261.
C．300. D．347.
6．Why is the percentage of genetic eye problems mentioned in paragraph 3?A．To show the significance of studying mice’s genes.
B．To prove mice’s genes are similar to humans’．
C．To warn the high risk level of suffering them.
D．To explain how common they are among people.
7．What should scientists do first to unlock secrets of genetic blindness?
A．Compare humans’ genes with mice’s.
B．Recognize each gene’s role of humans.
C．Set apart a gene of a mouse each time.
D．Figure out each gene’s function of a mouse.
8．What can be a suitable title for the text?
A．New Ways to Cure Sight Loss
B．Genetic Diseases Discovered in Mice
C．Genes Found Behind Eye Problems
D．Humans’ Genes Causing Eye Diseases

Humans are emotional beings，showing feelings in our behavior and facial expressions.But
whether these mean the same thing in different cultures has been hotly debated.Now a new study
has found that in different social contexts，such as weddings，funerals and sports，people indeed
show universal facial expressions.
For the new study，Alan Cowen’s team used a machine learning model，Deep Neural
Network(DNN) ， to systematically analyze facial expressions in thousands of different
contexts.These contexts come from more than six million videos uploaded to YouTube by people in
144 countries.
Facial expressions were rated by English speakers in India by selecting applicable emotions
from a list of 31 labels，resulting in a total of 16 distinct facial expressions.Meanwhile，contexts
were classified in a separate experiment.The results showed that people from different cultures
share about 70% of the facial expressions used in response to different social and emotional
situations.
“This supports Darwin’s theory that expressing emotions in our faces is universal among
humans，” the study co-lead author Dacher Keltner said.“The physical display of our emotions
may define who we are as a species，enhancing our communication and cooperation skills and
ensuring our survival.”
However，Lisa Barrett，from the Northeastern University College of Science notes that the
English speakers in India were given the emotional word ratings rather than labeling the
expressions themselves.They used emotion labels such as “anger” “fear” and “sadness”
instead of descriptive terms，thereby inferring the emotions behind the expressions.She further comments that the raters(评定者) saw the faces in contexts which can’t
necessarily be separated from the emotions themselves，and that the key point is that the raters are
from just one country.“The ultimate value of Cowen and his colleagues’ study might lie not in
the answers it provides，” she concludes，“but in the opportunity for further discovery that it
opens up.”
9．What can we learn from the text?
A．The study is opposite to Darwin’s theory.
B．People in different cultures show similar facial expressions.
C．The team conducted the study by downloading facial expressions.
D．Facial expressions and contexts were classified in the same experiment.
10．How did Alan Cowen’s team conduct the study?
A．By using a learning machine.
B．By uploading videos to YouTube.
C．By analyzing facial expressions.
D．By using emotion labels.
11．What can we infer from Dacher Keltner’s words?
A．Social success is dependent on facial expressions.
B．Facial expressions have constantly changed over time.
C．Social skills reflect the ability of one’s expression management.
D．Facial expressions play a vital role in humans’ development.
12．What is Lisa Barrett’s attitude towards the study?
A．Objective. B．Ambiguous.
C．Critical. D．Contradictory.

By 2025，water shortage will be a big problem for about 1.8 billion people.In a world where
water resource is increasingly short，nations cannot afford to waste it. 1 After we use water in
our homes and businesses，it is washed away，taking many valuable resources with it.
Waste water is rich in carbon and nutrients. 2 A number of nations and major cities have
already built waste water treatment plants.They can effectively recover nutrients and bio-energy，
and produce “new water” that can be reused.But more than 80% of all waste water still currently
flows into natural ecosystems，polluting the environment and taking valuable nutrients and other
recoverable materials with it.
3 This is still better than the situation in smaller cities.In Latin American countries，
those living in small and medium-sized cities at most treat it in the form of septic tanks(化粪池)
that lack regular and proper maintenance.
Imagine that outside one of these small cities lies a lovely piece of land：on the surface it isaesthetically(美学地) built and provides habitats for local wildlife.Beneath the surface is wetland
that treats waste water and produces energy.
The energy produced saved families from having to use firewood collected in the wild.This is
not a dream project. 4 A team of scientists have been looking into the potential of the
constructed wetland environments.Having analyzed 800 examples of biomass in more than 200
countries，they found that，depending on climate and the type of plant used in the construction of
this type of wetland，up to 45 hectares of land could be irrigated with waste water. 5
A．This can provide ready access to clean water.
B．But that is exactly what we do.
C．A constructed wetland environment is already in practice on a small scale.
D．There is no longer any good reason to waste any type of water.
E．If collected and treated properly，it could provide “new water”，fertilizer，and energy.
F．This would reduce the need for fresh water for irrigation and energy for pumping.
G．Although waste water systems in large cities are effective，the whole procedure usually costs
much.
