Fans of the movie Finding Nemo may remember the terrifying fish that scares Dory and Marlin at the
bottom of a trench.
But in reality this “monster”， a black seadevil, is only about 9 cm long, which would make it
about a third of the size of Dory and potentially smaller than Marlin or Nemo.
While this inaccuracy may seem harmless, it could cause problems for future conservation efforts, as
people are more likely to support conservation of adorable rather than scarylooking animals.
The black seadevil is just one of the mysterious “monsters”. From 2000 to 2010, scientists
described about 1 ， 200 new species in the Census of Marine Life.While this figure may seem
astonishing, a further 5，000 individual dead creatures are in specimen (标本) jars, waiting to be
described.
Specimens must be methodically collected, identified, and then the identity of new deepwater species
must be confirmed.
If we call unusual deepsea animals monsters, then we may harm their conservation as people are
unlikely to be connected with them or care about saving them.
On the other hand, their rarity clearly makes them popular on social media sites.For other species,
this has already resulted in increases in illegal trading for unusual pets.Deepsea species may potentially
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂become illegally obtained specimens or food.Humans may end up eating these animals of the deep sea to
extinction before their species are even known to science.
Every habitat on earth is interconnected, and whatever we as humans do has an influence on marine
ecosystems.In reality, about 80% of our oxygen is produced by microorganisms (微生物) in the oceans.This
makes our oceans both the lungs and lifeblood of our planet and we must all try harder to save them.
1．What can we know about the black seadevil?
A．People benefit greatly from the oxygen produced by it.
B．Its body size is a big threat to fish like Dory and Nemo.
C．Its scary appearance will cause problems for conservation.
D．People didn't know much about it when filming Finding Nemo.
2．What does the author think of the progress of describing new species?
A．Acceptable. B．Surprising.
C．Unsatisfying. D．Hopeless.
3．What does the underlined word “this” in Paragraph 7 probably refer to?
A．Their popularity on social media sites.
B．Their rarity among sea creatures.
C．Their conservation being harmed.
D．Their importance being ignored.
4．What can we infer about those unusual sea animals?
A．They are the lungs and lifeblood of our planet.
B．Confirming their identity is very urgent for protection.
C．Most of them are becoming illegally obtained specimens.
D．Adorable ones are more likely to be posted on social media sites.

（2022·全国·高考真题）Goffin’s cockatoos, a kind of small parrot native to Australasia, have been shown to
have similar shape-recognition abilities to a human two-year-old. Though not known to use tools in the wild, the
birds have proved skilful at tool use while kept in the cage. In a recent experiment, cockatoos were presented with a
box with a nut inside it. The clear front of the box had a “keyhole” in a geometric shape, and the birds were given
five differently shaped “keys” to choose from. Inserting the correct “key” would let out the nut.
In humans, babies can put a round shape in a round hole from around one year of age, but it will be another
year before they are able to do the same with less symmetrical (对称的) shapes. This ability to recognize that a
shape will need to be turned in a specific direction before it will fit is called an “allocentric frame of reference”. In
the experiment, Goffin’s cockatoos were able to select the right tool for the job, in most cases, by visual recognition
alone. Where trial-and-error was used, the cockatoos did better than monkeys in similar tests. This indicates that
Goffin’s cockatoos do indeed possess an allocentric frame of reference when moving objects in space, similar to
two-year-old babies.
The next step, according to the researchers, is to try and work out whether the cockatoos rely entirely on visual
clues (线索), or also use a sense of touch in making their shape selections.
1．How did the cockatoos get the nut from the box in the experiment?
A．By following instructions. B．By using a tool.
C．By turning the box around. D．By removing the lid.
2．Which task can human one-year-olds most likely complete according to the text?
A．Using a key to unlock a door. B．Telling parrots from other birds.
C．Putting a ball into a round hole. D．Grouping toys of different shapes.
3．What does the follow-up test aim to find out about the cockatoos?
A．How far they are able to see. B．How they track moving objects.
C．Whether they are smarter than monkeys. D．Whether they use a sense of touch in the test.
4．Which can be a suitable title for the text?
A．Cockatoos: Quick Error Checkers B．Cockatoos: Independent Learners
C．Cockatoos: Clever Signal-Readers D．Cockatoos: Skilful Shape-Sorters

（2021·全国·高考真题）If you ever get the impression that your dog can “tell” whether you look content or
annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human
faces, according to a new study.
Researchers trained a group of 11 dogs to distinguish between images (图像) of the same person making either
a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the
person’s face. The researchers then tested the dogs’ ability to distinguish between human facial expressions by
showing them the other half of the person’s face on images totally different from the ones used in training. The
researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses
more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during
training to new faces in the testing stage. “We can rule out that the dogs simply distinguish between the pictures
based on a simple cue, such as the sight of teeth,” said study author Corsin Muller. “Instead, our results suggest that
the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies
to an angry mouth having the same meaning as angry eyes.”
“With our study, we think we can now confidently conclude that at least some dogs can distinguish human
facial expressions,” Muller told Live Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial
expressions in humans. “To us, the most likely explanation appears to be that the basis lies in their living with
humans, which gives them a lot of exposure to human facial expressions, and this exposure has provided them with
many chances to learn to distinguish between them,” Muller said.
5．The new study focused on whether dogs can_________.
A．distinguish shapes B．make sense of human faces
C．feel happy or angry D．communicate with each other
6．What can we learn about the study from paragraph 2?
A．Researchers tested the dogs in random order.
B．Diverse methods were adopted during training.
C．Pictures used in the two stages were different
D．The dogs were photographed before the lest.
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂7．What is the last paragraph mainly about?
A．A suggestion for future studies. B．A possible reason for the study findings.
C．A major limitation of the study D．An explanation of the research method.
