On October 23，2020，scientists came across a white octopus （章鱼）with “wings” that looked more like a ghost from outer space than the eight - legged ones we are used to seeing.
The octopus’ scientific name is Grimpoteuthis.However，thanks to the two ear- like fins（鳍）on the sides of its body，it is better known as a dumbo octopus，after Disney' s animated （动画的）elephant.The sea creature also has eight legs connected to its body by a web of skin，which are used to increase the pace when faced with natural enemies like sharks.Dumbo
octopuses can also move across the seafloor using their tentacles（触须）.
While the one caught on tape was mostly white，dumbo octopuses，like other
octopuses，can
change
their
skin
color
in
different
environments.They，however，do not produce ink often used as a weapon by other octopuses.Instead，some dumbo octopuses have developed something sharp on their tentacles.
There are more than a dozen known species of dumbo octopuses.While most are small，measuring between 8 and 12 inches long，some can reach over 6 feet in length.Though octopuses have huge eyes，they can hardly see. However，although dumbo octopuses live in the deepest and darkest parts of the Atlantic and Pacific Oceans，where nothing can be seen，the lack of sight does not affect them.Instead，they have learned to use the suckers（吸盘）on their tentacles to feel their surroundings.
Their deep－sea environment makes these octopuses difficult to spot，which is why any sighting of the unusual creatures is met with such joy.The latest one，caught on camera by Hercules，an unmanned robot，was discovered two miles underwater around the Davidson Seamount，a volcano in California.

What kinds of rooms are your favorite spots for studying? We are going to guess that they are probably not painted bright red or yellow. But maybe they should be.Imagine.You are suddenly asked to prepare for an exam.You have two rooms to choose from.One is a pale blue，and the other is a bright red.Which one do you settle into for study? Is one going to get your brain
fired up for learning，or let you relax into the best state of concentration?
According to researchers at Curtin University in Australia，it might be best to camp out in the bright red room when you are looking to store information.It might sound strange，since we often think of pale rooms ---soft blues or light greens---are relaxing.And they seem to be：The Curtin University study showed that pale colors made participants feel more relaxed and calm，while bright colors increased heart rate.But calming and relaxing，it turns out，may not always be the best environment for deep concentration or knowledge gaining.Reading comprehension was much better in the bright rooms than in the pale rooms.Although participants reported that they generally preferred the pale rooms to study in as an approach to relax into work，the researchers saw just the opposite ---that the bright - colored rooms seemed to lead to greater concentration.
While this might seem only surprising，the findings get into a rather controversial （有争议的）area of psychological study.The Yerkes - Dodson Law says that a little bit of stress is good for achieving best performance，while too much stress negatively affects it.The higher heart rate and the reports of the bright colors creating a heavy atmosphere might just suggest that a little stress was good for the brain.
28.What is the common idea mentioned in the first paragraph?
A.Pale colors appeal to all tastes. B.Few people like bright red or yellow.
C.Light - colored rooms make you feel nervous. D.Bright - colored rooms are not good for studying.
29.What might directly affect the research results according to Para 2? A.How participants react to colors. B.Participants’s preferences in colors.
C.What participants read in the rooms. D.Time participants spent in the rooms.
30.What can be concluded from the study by Curtin University? A.Higher stress leads to better performance. B.Most people know how to make use of colors. C.Stress is necessary when you want to concentrate. D.Being relaxed is very important for people studying. 31.What’s the main idea of the text?
A.Findings about people's favourite room colors. B.Room colors can affect one’s academic performance. C.Bright - colored rooms can create a heavy atmosphere. D.Light - colored rooms help people feel relaxed into work. D
