How to Create a Mind Map

Most of us think visually but we write textually. 1. It also makes the information we list more difficult to process, remember, and share.

2. It combines the brain’s visual nature with our tendency to write down words. We end up with a diagram that combines logic and order in a less structured manner. This promotes clearer thinking and better comprehension. 3.

So, how do you create a mind map? The most basic method is to just use a pen and paper, or a marker and whiteboard. It begins with a central topic or idea, then flows outward. 4. The next level of topics is represented by branches extending from it.

There aren’t really any rules for creating mind maps. While most flow outwardly from the central topic, some users prefer to build mind maps in one direction. 5. This can make groups of ideas easier to identify and remember. It also makes a mind map more enjoyable to create and use.

Mind maps are extremely effective for taking notes, planning a project, brainstorming an idea, presenting information to others, and many other uses. Take out your pen and have a try.

A. They help to clarify thinking.

B. This goes against how our minds actually work.

C. They help us save time by focusing on key issues.

D. A mind map is the perfect answer to this dilemma.

E. Think of it as a tree, where the central point is the trunk.

F. It’s also a lot more enjoyable than simply writing down lists.

G. Others like to add colors, pictures, or symbols in their mind maps.

Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years.

Scientists know that Earth formed about 4. 5 billion years ago.　 They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust （地壳), eventually formed moving plates. Exactly when this shift happened, however, is an open question.

Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago. The new estimate is l. 3 billion years earlier than previous ones.

Not long before 3. 8 billion years ago,　 lots of small planets were hitting Earth, keeping its crust in a hot, melting state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface.

In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal (上地壳) belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor, but now it is exposed to air.

The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks（裂缝）in the rock that have been filled in with a type of volcanic rock.

To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock oozed from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today.

That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of plate under the ocean, beginning around 3.8 billion years ago.

“It's a fantastic case of solving a jigsaw puzzle（拼图）,”says one of the researchers. He notes that the puzzle was “a very difficult one because these rocks are all very old and have been badly ruined".

1.The underlined phrase “oozed from" in Paragraph 7 is closest in meaning to________.

A. filled up gradually

B. washed away quickly

C. flew out of slowly

D. broke through suddenly

2.What can we infer from the text?

A. The shapes of continents and oceans changed slowly.

B. The Earth's crust started shifting l.3 billion years ago.

C. The crust began to shift when the Earth was hot.

D. The hit from small planets made the Earth cool.

3.What do scientists know about the past of the Isua supracrustal belt?

A. It was once covered by hot, liquid rock.

B. It remained under the deep sea.

C. It stayed hot and sinking.

D. It kept moving slowly.

4.The text is mainly about________.

A. why the Earth cooled

B. how the Isua supracrustal belt formed

C. whether the ground beneath our feet is still

D. when Earth's crust began shifting

Many of us would like to spend all of our time helping dogs in need, but it can be hard to carve out that kind of time. Well, one man, Eugene Bostick, decided that when he retired, he would devote the rest of his life to helping homeless dogs feel loved.

Eugene Bostick was fortunate enough to be able to retire at the ripe age of 65 after working his entire life on his farm. His farm was located at the end of a dead-end street, and he noticed that people would, unfortunately, abandon their dogs on the farm and race off.

Eugene refused to see these pets suffer, and he quickly picked up these abandoned dogs, giving them food and taking them to the vet to make sure they were spayed and neutered.

The dogs quickly got on the train, and together, they spent hours traveling around town and through the forests nearby.

After they were spotted around town, one neighbor took a picture of Eugene that went viral, and a GoFundMe page was started that gained plenty of donations. Eugene was amazed by everyone’s generosity, and was happy to see others help these abandoned animals feel loved. Eugene will continue to care for his dogs, and we should all follow his lead!

We humans spend about one-third of life asleep. Sleep helps us stay healthy, and it also helps our brain remember. Our brains need good sleep to remember what we do and learn during the other two thirds of our life when we are awake. Besides keeping us healthy, some new research shows that a good night’s sleep helps make us more intelligent.

Researcher at the University of Wisconsin-Madison have found that sleep helps improve brain performance by shrinking synapses in the brain. A synapse is the area where cells pass messages to other cells.

Cirelli is a leading scientist at the school’s Center for Sleep and Consciousness. She found that sleep is when the human brain mixes information it has learned while awake into its general collection of knowledge. However, the brain forgets unimportant details. This forgetting is important. It makes space for new learning and new memories.

Cirelli said that the Center’s research began with this hypothesis: We sleep so that our brain can repair and refresh itself. She said the idea seems simple and reasonable. However, testing and discovering how it works has been extremely difficult. Cirelli and Center director Giulio Tononi have been trying to prove the connection between sleep and the brain’s synapses since 2003. Cirelli said the researchers knew that “stronger synapses are also bigger.” So, they began their study by “measuring the size of the synapses” in the brain.

They also knew that during sleep, the brain checks on all its synapses and resets itself for the next day. The team wanted to see if the synapses of the brain are bigger after being awake all day and smaller after a good night’s sleep. Synapses are only about 20-40 nanometers wide. So, the team looked for changes in these already tiny spaces between nerve cells. The team had lo wail until improvements in laboratory technology made it possible to see these tiny changes.

Cirelli says they found that synapse size and strength are upset by being awake and restored by sleeping. She says our synapses shrink as our brains clean themselves during sleep. We wake up refreshed and ready to fill those synapses with new information.

1.Which of the following statements is true according to the passage?

A. Sleep can only keep us healthy.

B. Sleep can help our brain function better.

C. Sleep can mix all the information.

D. Sleep can take up two-thirds of our life.

2.What does it refer to in Paragraph 4?

A. The measuring the size of the synapses.

B. The space for new learning and new memories.

C. The way our brain can repair and refresh itself.

D. The connection between sleep and the brain’s synapses.

The intelligence times provide us much convenience，but at the same time，some of our abilities are being weakened gradually.

1. Memorizing phone numbers

It was annoying to remember numbers. Now we simply add them to our contacts list. That usually works well unless our device is lost，stolen，or damaged. No one can be expected to remember all their contact numbers. What we can do is memorize 5 of our most important contact numbers. This should include a mixture of family，friends and business. If you're really ambitious you can memorize 5 contacts for each category.

2. Map-reading skills

The convenience and effectiveness of GPS guidance systems and digital maps generated by search engines is unquestionable. They've definitely made our lives easier. What we don't get from using these devices and applications is the increased ability to understand spatial orientation（空间方向）and navigation.

To renew or acquire those skills，try using physical maps to plan your next trip. After a few trips，you'll be pleasantly surprised with how useful a physical map can be.

3. Photography

Even amateur photography requires a basic learning about lighting，depth，and composition. This is true for digital photography. Most smart cameras automatically make these adjustments. We no longer have to learn the art of photography. On most devices，this is easily changed by turning off the automatic settings. Experiment with setting by hand the scene modes，lighting，and zoom. You just may learn that you're a “true photographer”.

4. Reading comprehension

The primary cause is E-reader. They're convenient and can store thousands of books. But there's evidence that E-reader makes it more difficult for readers to keep and recall information they just read. Don't worry! What we should do is make an effort to read printed books. This will be especially helpful when seeking information we need for academic or career purposes.

5.Hand-written correspondence（通信）

Writing letters and notes include hand writing skills，organizational skills，and learning about the person or persons you correspond with. This is another easily regained skill. Send a letter to an old friend，relative or acquaintance.

1.What's the disadvantage by adding all numbers to the contacts list?

A. We may only have the ability to remember 5 numbers.

B. It's hard to find the number from the contacts list.

C. We might lose all our phone numbers accidentally.

D. Our device is more easily damaged or stolen.

2.To make yourself a “true photographer”，you ______.

A. must make it clear how the digital camera works itself

B. have to make your camera do the adjustments automatically

C. don't need to learn the art of photography

D. had better try to set the scene modes，lighting，and zoom by hand

3.E-readers are thought to weaken our reading comprehension because ______.

A. they are convenient and can store thousands of books

B. they make it more difficult for us to recall information

C. less people can afford to buy E-readers

D. people are not fond of reading printed books nowadays

4.The author of the text seems to ______.

A. be worried that we might lose some basic abilities in intelligence society

B. point out to us the abilities one should have for adapting to the modem society

C. be glad that people will regain these abilities by using them often in daily life

D. find out that these abilities will probably make modern people different from before
