If you could be anybody in the world, who would it be? Your neighbouror a super star? A few people have experienced what it might be like to stepinto the skin of another person, thanks to an unusual virtual reality device.Rikke Wahl, an actress, model and artist, was one of the participants in a bodyswapping experiment at the Be Another lab, a project developed by a group ofartists based in Barcelona. She swapped with her partner, an actor, using amachine called The Machine to Be Another and temporarily became a man. "AsI looked down, I saw my whole body as a man, dressed in my partner'spants," she said. "That's the picture I remember best."

The set-up is relatively simple.Both users wear a virtual reality headset with a camera on the top. The videofrom each camera is sent to the other person, so what you see is the exact viewof your partner. If she moves her arm, you see it. If you move your arm, shesees it.

To get used to seeing anotherperson's body without actually having control of it, participants start byraising their arms and legs very slowly, so that the other can follow along.Eventually, this kind of slow synchronised（同步的）movement becomes comfortable, and participants reallystart to feel as though they are living in another person's body.

Using such technology promises toalter people's behaviour afterwards-potentially for the better. Studies haveshown that virtual reality can be effective in fighting racism-the bias thathumans have against those who don't look or sound like them. Researchers at theUniversity of Barcelona gave people a questionnaire called the ImplicitAssociation Test, which measures the strength of people's associations between,for instance, black people and adjectives such as good, bad, athletic orawkward. Then they asked them to control the body of a dark skinned digitalcharacter using virtual reality glasses, before taking the test again. Thistime, the participants' bias scores were lower. The idea is that once you've"put yourself in another’s shoes" you're less likely to think ill ofthem, because your brain has internalised the feeling of being that person.

The creators of The Machine to BeAnother hope to achieve a similar result. "At the end of body swapping,people feel like holding each other in their arms," says Arthur Pointeau,a programmer with the project. "It's a really nice way to have this kindof experience. I would really, really recommend it to everyone."

1.The word "swapping" (paragraph 1) is closest in meaning to______.

A. building

B. exchanging

C. controlling

D. transplanting

2.We can infer from the experimentat the Be Another lab that______.

A. our feelings are related to our bodily experience

B. we can learn to take control of other people's  bodies

C. participants will live more passionately after the  experiment

D. The Machine to Be Another can help people change  their sexes

3.In the Implicit Association Test,before the participants used virtual reality glasses to control a dark skinneddigital character, ______.

A. they fought strongly against racism

B. they scored lower on the test for racism

C. they changed their behaviour dramatically

D. they were more biased against those unlike them

4.It can be concluded from the passage that______.

A. technology helps people realize their dreams

B. our biases could be eliminated through experiments

C. virtual reality helps promote understanding among  people

D. our points of view about others need changing  constantly

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.
