2651．We already know that salt can lead to heart disease.But could it also affect our mind？Scientists found that a high-salt diet caused cognitive impairments in mice and it could produce the same effect on humans.
Costantino Iadecola，director of the Feil Family Brain and Mind Research the Institute，said they fed the mice eight to sixteen times their normal salt intake and then tested the mice.After about three months，the mice had a big change in their behavior.Mice are very curious，and they like to look for new things.However，the tested mice lost the ability to identify a normal object.When the mice were put in their cage and asked to find a quiet spot，they did not remember where the quiet spot was.Then when the mice were building a nest，which is something the mice do daily，they，were unable to do so.The research suggested humans would experience a similar response.
Studies have shown Australians eat around double the recommended amount of salt each day，most of it coming from processed food.Dr.Ladecola said the estimated two teaspoons of salt the average Australian eats each day could affect the brain function in the long term.However，the decline might not be as obvious as in the mice，who were given extremely high levels of salt. "But probably over years and perhaps decades-as opposed to a few months for the mouse-even lower levels of salt may have a terrible effect，" Dr ladecola said.
"High levels of salt cause serious immune changes in the organs in and around the stomach，resulting in an almost autoimmune effect on the brain.It is part of a growing body of evidence that we really are what we eat，" Bryce Vissel，director of the Centre for Neuroscience at the University of Technology Sydney，said. "Those changes in turn cause all sorts of responses in the body，which over time certainly contribute to cognitive impairments."

Disney World and Disneyland are well-known for being the happiest places in the world，but sometimes，some bad things happen.When they do，staff have code words to let other staff know what has taken place without destroying your perfectly happy day with terrible details.
According to the New York Post，one of the code words you can hear a worker say at Disney World is "White Powder Alert".A "White Powder Alert" means that a guest has brought the ashes of their dead relatives in order to make the happiest place on Earth their final resting place.According to Susan Veness，author of Walt Disney World Hacks，this most commonly occurs on the Haunted Mansion ride.This is both illegal and can get you banned from Disney forever.
The second Disney code word you never want to hear is "E-stop".This one is a bit more straightforward（直截了當(dāng)?shù)模?and isn't used just for Disney.In order to remain as perfectly clear in an emergency situation as possible，workers in most amusement parks use the same phrase.It means "Emergency Stop".If a ride must be shut down due to a sanitary（衛(wèi)生的）issue-like someone getting sick or pouring ashes-or a safety issue，an E-stop is called and the ride is instantly shut down while park officials decide if the ride should be evacuated（疏散）immediately or simply paused for maintenance.No matter what code words are said，you'll never want to hear a Disney cast member use these words.
（1）Why do staff in Disneyland use code words？
A．They make other staff know situations better.
B．They try to make tourists have a good day.
C．They want to make bad things happen less.
D．Code words make communication easier.
（2）What will happen if a tourist brings ashes of the dead to Disneyland？
A．Susan Veness will criticize him seriously.
B．He will be driven to the Haunted Mansion ride.
C．He will be forbidden to go to Disneyland forever.
D．He will get no place to rest in Disneyland.
（3）Who makes a decision to make a ride be paused according to the text？
A．People repairing the machine.
B．People using code words.
C．People in charge of sanitary.
D．People in charge of the park.
（4）What can be a suitable title for the text？
A．Beautiful Disneyland That is Attractive and Magical
B．Two Code Words That You Never Want to Hear in Disney
C．Some Emergency Cases That Happen in Disneyland
D．Advice That Makes You Have a Good Time in Disney發(fā)布：2024/12/15 4:0:1組卷：10引用：1難度：0.62656．The father's always telling her what to do， but she usually just

He ran back and forth，as hard as his ten-year-old legs would carry him，looking back（9）at the kite behind.After about ten minutes of unsuccessful trying，he came back in.
I asked，"How did it（10）？" "Fine，" he said，not wanting to admit（承認(rèn)）the failure. "I got it to fly some. "However，I heard him say secretly，" I guess I'll have to wait for the（11）. "

Google Maps and GPS are modern wonders that have gotten me out of many confusing places，but paper maps still have a role to play in our lives.Most of us adults learned to read them out of necessity，but it's up to us to pass on that skill to children whose need may not be so obvious，but who still stand to benefit from it.
As Trevor Muir wrote in an article on this topic，"When kids learn how to create and use paper maps，they are doing more than just learning how to get around.They are actually developing fundamental skills that they will use for the rest of their lives.Map skills still belong in today's classroom."
As a child I had National Geographic maps taped to my bedroom walls.This aroused my curiosity and imagination about those places and thus made me eager to remember my geography and history lessons because they were tied to places I'd "seen".Even now as a mother of four，I've also spared time to travel to many of the countries whose maps I studied as a child.
Additionally，in this fast-changing world，unexpected events can rapidly influence one's usual way of life.When GPS satellites or Internet connections are affected，this old-fashioned skill can get you out of a mess without requiring a smartphone.Last but not least，paper maps arouse "big picture" thinking，showing kids that there's a much bigger world out there and helping to direct them within it.
So，now is a good time to pull out those dusty old maps and lay them on the kitchen table.
（1）How did the children react when they were given the paper map？
A．They showed great curiosity.
B．They seemed totally confused.
C．They considered it old-fashioned.
D．They found it less convenient than GPS.
（2）What might be the topic of the article written by Trevor Muir？
A．The teaching focus in today's classroom.
B．The situations where paper maps are used.
C．The necessity of digital maps in the modern world.
D．The benefit of developing paper map skills for kids.
（3）Which of the following shows the author's opinion？
A．Internet connections are very reliable today.
B．GPS will sooner or later replace paper maps.
C．Paper maps provide kids with a grand vision.
D．Paper maps make people connected with each other.
（4）What would be the best title for the text？
A．Time to Teach Kids to Read Paper Maps.
B．How to Teach Kids about Different Kinds of Maps.
C．Time to Encourage Kids to Step into a Bigger World.
D．How to Teach Kids Fundamental Skills with Paper Maps.發(fā)布：2024/12/15 3:30:1組卷：2引用：4難度：0.5
