We all have a favorite independent pet shop, where we always pick up the tastiest treats and best dog
toys. And now, it’s time to celebrate these small shops! This year, Beco, the UK’s leading pet brand, is
launching the Independent Pet Shop Awards to champion the brilliant people who work tirelessly managing
the independent pet shops we love.
Procedure:
Register at TeamDogs and answer a question. Beco will ask people to nominate (提名) their favorite
independent pet shops. Judges will visit the nominees before crowning (为……加冕) one of them the UK’s
Favorite Independent Pet Shop. To award the participants, Beco is giving away a dog hamper (盒装食物)
worth £150 to five lucky winners at TeamDogs.
George Bramble, Beco’s co-founder, says, “Britain is a nation of pet lovers, and this has never been
more obvious over the past year. We have relied on local pet shops for all our pet care needs, and now
we’re calling on people throughout Britain to thank these champions by nominating their favorites and
encouraging people to support their local pet shops.”
The COVID-19 made everyone on the high street tough, but with 3.2 million people becoming new
pet owners last year, pet shops have been working harder than ever before with home deliveries,
community support and advice given on nutrition or pet care.
Tips:
Nominations are now open on www.becopets.com and will close on June 6th. The final winner will be
announced in July.

Published in 1859, Charles Darwin’s On the Origin of Species made a number of brave claims about
the nature of evolution—including the suggestion that an animal species with greater diversity in its line
will produce more subspecies too. This assumption is not as obvious as you might think at first. And it was
finally found to be true for birds only a couple of years ago. Now, researchers from the University of
Cambridge in the UK have shown that Darwin was right on this point for mammals (哺乳动物), too.
Apart from being an important contribution to our understanding of evolution in general, the findings
could also be useful in ongoing conservation efforts—helping experts to figure out which species need to
be protected in order to ensure their survival.
“My research investigating the relationship between species and the variety of subspecies proves that
subspecies play a vital role in long term evolutionary dynamics and in future evolution of species,” says
biological anthropologist Laura van Holstein. There are three subspecies of northern giraffe, for example,
and 45 subspecies of the red fox—the highest in the animal kingdom. 36 different species of wild cats have
been found and most of these are further divided into subspecies. Human beings, on the other hand, don’t
have any subspecies.
To test Darwin’s assumption, van Holstein looked at a huge database of animal classifications,
analysing the collected knowledge we have about mammal species and subspecies to look for patterns. The
data showed that habitat (land versus sea, for example) plays an important role in subspecies’ form and
increase. The findings show that those living in the sea, or spending a lot of time in the air are less affected
by physical boundaries like mountains.
The discoveries on subspecies habitat are particularly significant when it comes to conservation,
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂because the habitats of so many animals are under threat from climate change and human activity, and these
findings indicate that our actions are really having an effect on the process of evolution.
4. What is the main idea of the first paragraph?
A. Charles Darwin’s claims have been proved recently.
B. Charles Darwin published On the Origin of Species.
C. Charles Darwin’s assumption was right for any animal.
D. Charles Darwin set up the foundation of evolution theory.
5. What can we infer from Laura van Holstein’s research?
A. Humans will evolve faster.
B. Northern giraffe’s evolution is less active.
C. The red fox needs immediate protection.
D. Wild cats’ subspecies are countless.
6. Which of the following animals’ subspecies may be less affected?
A. Dogs. B. Sharks. C. Monkeys. D. Snakes.
7. Why are the discoveries on subspecies habitat important?
A. Because they help solve the threat of climate change.
B. Because they show human activity is bad for evolution.
C. Because they tell the importance of conservation of habitats.
D. Because they prove evolution is damaged by human actions.

The fish eggs, all 200 of them, were settled and ready to go. The ground crew had counted the eggs
carefully, and sealed them tightly within a plate filled precisely to the edge with seawater.
The countdown, and then—ignition (点火)! For two full minutes, the precious eggs suffered a violent
shaking as the rocket’s engines exploded to life, and then rise to the heavens. These eggs were on their way
to low Earth orbit. Next stop: the moon.
Well, they haven’t actually left yet. But after a recent simulation (模拟) designed to re-create the
intense shaking of a typical takeoff, researchers in France found that the eggs survived. It’s a crucial
discovery in the progress of the Lunar Hatch, a program that aims to determine whether astronauts could
successfully raise fish on a future moon base.
Finally, Cyrille Przybyla, an aquaculture (水产养殖) researcher at the French Research Institute for
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂Exploitation of the Sea who led the research, dreams of designing a lunar fish farm that uses water already
on the moon to help feed residents of the future Moon Village set to be established by the European Space
Agency (ESA).
Przybyla’s hope is to offer lunar residents fresh, inviting, protein-rich fish—not just packets of freeze-
dried food. “I proposed the idea to send eggs, not fish, because eggs are very strong,” he says.
Besides, Przybyla suggests there will be other benefits for astronauts who may one day find
themselves raising animals in space. “From the psychological point of view, it’s better to have a reminder
of Earth–you have a garden; you have a tank with fish,” he says.
Designing self-contained and self-supporting systems for food production beyond Earth will be crucial
for future space exploration programs, says Luke Roberson, a researcher at NASA’s Kennedy Space Center
in Florida. And he says Przybyla’s study is “a great first step” toward showing that aquaculture is a
practical part of that future.
8. What is Paragraph 2 writing about?
A. An experience. B. An experiment.
C. An imagination. D. An adventure.
9. Why do the researchers want to send the eggs to the moon?
A. To offer eggs to astronauts as food.
B. To test whether the eggs are strong.
C. To promote aquaculture on the moon.
D. To see the possibility of raising fish on the moon.
10. What’s the psychological advantage of raising animals in space?
A. It can get rid of loneliness.
B. It diversifies the space food.
C. It gives astronauts something to do.
D. It helps astronauts remember the Earth.
11. Which of the following can be the best title for the text?
A. How to Send Eggs to The Moon
B. A Great First Step towards Future
C. The Plan to Raise Fish on The Moon
D. A Practical Approach to Aquaculture

A shark attacked a 14-year-old girl near a Florida beach on Saturday, though a surfer tried to save her.
The surfer pulled the girl from bloody water and frightened the shark away with his fists（拳头）.
Can sharks really smell blood in the water? Yes. Sharks have a good sense of smell, and blood happens
to be a very attractive smell. Sharks also use sight and hearing to discover their food. In particular, hungry
sharks like to hear the sounds which are made by swimming fish. They also look for something bright.
Attacks on people can sometimes be a case of mistaken recognition. Sometimes, a shark could confuse
shining stones for food.
The sharks’ eyes, ears, and nose are all near their mouth. But sharks also search for their food with
sensory receptors（感受器）. These receptors can feel any movement in the water. When a shark gets very
close to a food, it can use electroreceptive organs（电觉器官）, which sit the wall of little holes on the
shark’s nose. Living things in salty seawater produce a weak electrical field（电磁场）that the shark can
feel at a short distance, so it allows the shark to find out creatures that bury themselves in the sea floor.
Muscle（肌肉）movements also produce little electrical fields that a shark can feel.
The surfer who tried to save the girl said he protected himself by frightening away the shark with his
fists. Is that a good idea? Some experts think frightening away a shark with fists should only be the last
choice. It won’t be wise for you to stay still in water. Swimming away rapidly seems to be a better choice.
If you can’t swim away right away, hit the shark on the face or nose—where it has a high concentration of
sensory receptors like humans—to drive off your attacker and give you enough time to escape. When you
are beside a shark’s face, try sticking your finger in its eyes.
12. Which of the following helps sharks search for food?
A. Swimming quietly. B. A special kind of blood.
C. Working as a team. D. A good sense of smell.
13. What can we infer from paragraph 3?
A. Sharks can feel movements from other creatures in seawater.
B. Sharks use sensory receptor more than smell to search for food.
C. Sharks can’t feel weak muscle movements from other creatures.
D. Sharks can’t find and attack creatures hiding in the sea floor.
14. What are we advised to do when we are attacked by a shark?
A. Shout loudly and frighten it away. B. Get away from it immediately.
C. Touch the shark’s face gently. D. Stay still to pretend to be dead.
