How to Remember What You Read
Reading is important, but the next important step is making sure that you remember what you've read! 1.You may have just read the text, but the ideas, concepts and images may fly right out of your head. Here are a few tips for remembering what you read.
Are you confused?
If the plot, characters, or word usage is confusing for you, you likely won't be able to remember what you read. 2. If you don't understand what you're reading, how would you remember it? There are a few things you can do--use a dictionary ； look up the difficult words； consult a teacher...
Are you connected?
Does a character remind you of a friend? Does the setting make you want to visit the place? Does the book inspire you and make you want to read more? With some books, you may feel a connection right away. 3.How willing are you to make the connections happen?
Read it; hear it; be it!
Read the lines. Then, speak them out loud. And, put some character into the words. When he was writing his novels, Charles Dickens would act out the parts of the characters. He'd make faces in the mirror and change his voice for each character. 4. .
How often do you read? If you read frequently, you'll likely have an easier time with remembering what you're reading and what you've read. 5.As you make reading a regular part of your life, you'll make more connections, stay more focused and understand the text better. You'll learn to enjoy literature--as you remember what you read !
A.What's your motivation?
B.Practice makes perfect.
C.It's a bit like reading a foreign language.
D.Marking helps you remember what you read.
E.Memory is sometimes a tricky thing.
F.But other books require a bit more work on your part.
G.You can do the same thing when you are reading the text!
If you could change your child's DNA in the future to protect them against diseases, would you? It could be possible because of technology known as CRISPR- Cas, or just CRISPR.
CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part of DNA； it also uses an enzyme (If) that can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly.
The uses of CRISPR could mean that cures are developed for everything from Alzheimer's to cancer to HIV. By allowing doctors to put just the right cancer-killing genes into a patient's immune system, the technology could help greatly.
In April scientists in China said they had tried using CRISPR to edit the genomes (基因组)of human embryos. Though the embryos would never turn into humans, this was the first time anyone had ever tried to edit DNA from human beings. With this in mind, the US' National Academy of Sciences plans to discuss questions about CRISPR s ethics(伦理问题).For example? CRISPR doesn't work properly yet. As well as cutting the DNA it is looking for, it often cuts other DNA, too. In addition, we currently seem to have too little understanding of what DNA gives people what qualities.
There are also moral questions around playing God”. Of course, medicine already stops natural things from happening-for example, it saves people from infections. The opportunities to treat diseases make it hard to say we shouldn't keep going.
A harder question is whether it is ever right to edit human germ-line(种系)cells and make changes that are passed on to children. This is banned in 40 countries and restricted in many others. However, CRISPR means that if genes can be edited out, they can also be edited back in. It may be up to us as a society to decide when and where editing the genome is wrong.
Also, according to The Economist, gene editing may mean that parents make choices that are not obviously in the best interests of their children: “Deaf parents may prefer their children to be deaf too； parents might want to make their children more intelligent at all costs.
In the end, more research is still needed to see what we can and can't do with CRISPR. “It's still a huge mystery how we work,” Craig Mello? a UMass Medical School biologist and Nobel Prize winner, told The Boston Globe, "We're just trying to figure out this amazingly complicated thing we call life.

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces(熔炉)that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what's left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can flee. The star becomes black when there is no light. Then a black hole is born!
That's what we know about black holes. What we don't know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn't keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly-somewhere else. But where? A different place, perhaps, or a different time-many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black holes must remain a mystery.
Black holes are a mystery-but that hasn't stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth's energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste-a sort of huge waste disposal(处理)in the sky!

I am the proud owner of three pet dogs. Over the years, I have watched their behaviours carefully that help me when I travel around the world.
One important lesson that my dog, Cody, taught me is how to deal with little problems in life. From his calm behavior when someone knocked unexpectedly at the door to the indifferent way he has dealt with his recent serious illness, he has always had the same easy-going attitude. This attitude is an important lesson to me in how I can face difficult situations when travelling, I've learned to try to handle bad situations calmly, such as when we miss a train? lose luggage? and so on.
Another dog of mine, Preston, loves to walk around the yard, spending hours smelling every place and finding out what it means to him. Taking it slowly is another lesson that's been very hard for me to learn. As an active traveller, I am actually experiencing less by speeding through everything, rather than slowly getting to know a place. Even if it means that you won't see as many things, going slowly when you travel is the only way to really get to know a new place. Rushing around a foreign city isn't fun at all.
My dog, Moya, came from a truly bad situation. I am not sure what happened to her before； I just know it wasn't good. And while she has become more relaxed over the years, she is still slightly on edge. She is very cautious when faced with any new situation. But once she's accustomed to her new surroundings, she is fine. She doesn't let fear influence her experience. The same can be applied to our travel experience. No matter where we go, we need to manage new situations with caution--while at the same time not letting that caution turn into fear.
Many thanks to my pets. Truly speaking, pets are as basic to American culture as hot dogs or apple pies. To Americans, pets are not just property, but a part of the family. After all, pets are people, too, with the help of whom I am able to gain a lot and live differently.
