Living abroad will make you a different person and it will change you forever in a good way. I lived abroad for more than four years. 1.. Here are the most important four reasons why you should study abroad and make the most of your stay abroad.

Improve your job chances. 2.. HR managers value international experience highly, as candidates with experiences of studying abroad are considered to be adaptable, independent, problem-solving and open.

3.. Getting out of your home is certainly not easy, but it will help you grow. Go out there and experience the world. See it as an adventure that you will tell your grandkids about. Sometimes you have to push yourself and then you will be rewarded with this awesome feeling of accomplishment.

Create a memory of a lifetime. Spending time abroad will be an adventure and those memories will last for a lifetime. I know a lot of people that once lived abroad and none of them regrets the time they spent abroad. Yes, there will be difficult times. When you don’t understand the people around you everything is foreign and nothing makes sense. Everyday tasks seem like a major problem. 4..

Become independent. Living in a foreign country all by yourself will surely make you independent. You are forced to make decisions by yourself as you don’t have other choices. 5.. Show them that they were all so wrong about your being a mama’s boy (or girl)! It will feel great!

A. Get away from home.

B. Improve your language skills.

C. It was and still is the biggest adventure in my life.

D. Show yourself, your parents and friends that you can do it.

E. Different cultures have different values, traditions and customs.

F. But I can tell you from my experience that it is definitely worth it.

G. Experience abroad will give you an advantage over other applicants in the job market.

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.

1.What is the passage mainly about?

A.What we can and can't do with CRISPR.

B.How CRISPR was developed by scientists.

C.The advantages of CRISPR and arguments about its ethics.

D.Scientists' experiments of using CRISPR to edit human embryos.

2.According to the passage, the technology of CRISPR .

A.is very safe because it only cuts the DNA it is looking for

B.is banned in most countries and restricted in many others

C.could cause parents to make unwise choices for their children

D.could help us discover the link between DNA and the qualities it gives people

3.It can be inferred from the passage that .

A.all diseases could probably be cured through the uses of CRISPR

B.scientists had never edited genomes before CRISPR was invented

C.CRISPR is a technology that uses an enzyme to work on RNA and DNA

D.CRISPR has proven to be the most effective way to protect children against diseases

4.What is the author's attitude towards CRISPR?

A.Supportive. B.Worried. C.Negative. D.Objective.

A trip to the theater, museum or art gallery could help you live longer. And the more often you get that culture fix the better, a new study suggests.

Researchers from University College London (UCL) found that people who engaged in the arts more frequently—every few months or more—had a 31% lower risk of dying early when compared to those who didn’t. Even going to the theater or museum once or twice a year was linked with a 14% lower risk.

“While other health behaviors like smoking, alcohol and exercise are undoubtedly bigger predictors of death rate, these leisure and pleasure activities that people don’t think as a health related activity do support good health and longevity.” said Daisy Fancourt, an associate professor at UCL’s Research Department of Behavioural Science and Health.

The study looked at a range of economic, health and social factors to try and explain why there is a link between “arts engagement” and living longer, although as an observational study it can’t establish cause. Part of the reason, the study said, comes down to social and economic differences among those who go and don’t go to museums, exhibitions and art galleries.

Wealth, they found, explained about 9% of the association. Cognitive differences, social and civic engagement, mental health, mobility and deprivation also played a role. Things like free time and occupational status made no material difference.

The study says that engaging with the arts can reduce stress and build creativity that allows people to adapt to changing circumstances. It also helps people build social capital—accessing emotional support and information that helps people age more successfully.

Everyone should have the chance to take part in cultural activities and the study added weight to growing concerns about the decline in arts subjects in schools and universities.

1.What are the statistics in Paragraph 2 about?

A.Connection with art.

B.Risk of dying early.

C.Chances of healthy living.

D.Frequency of art engagement.

2.What does Fancourt think of going to the concert?

A.It contributes to living healthier and longer.

B.It can improve peopled cultural awareness.

C.It is a good behavior like smoking or exercise.

D.It offers people opportunities to become artists.

3.What can we infer from the text?

A.People who have more free time enjoy visiting museums.

B.Social status plays an important role in leading a happy life.

C.Everyone taking part in art related activities can live longer.

D.There should be more arts subjects in schools and universities.

4.Why did the researchers carry out the study?

A.To find the cause of building creativity.

B.To promote the mental health of the old.

C.To analyze the link between arts and life.

D.To influence the social behavior of people.
