There are many idioms in English. An idiom is a phrase that we can't understand from the meaning of each word. The following are some of them.

As the crow flies

    When a bird flies from place to place, it takes the most direct route. But when people drive, they have to follow roads and often go farther. When people give a distance "as the crow flies", they mean the shortest distance between the two points, not the distance you would have to travel by following roads.

    As Dan and his mum drove along the river, they could see the beach on the opposite side. Dan asked "How far is it to the beach?"

    "It's only about a quarter of a mile as the crow flies" his mother said.

Blow hot and cold

    In one of Aesop's Fables, a man blows on his fingers to warm them up and then blows on his soup to cool it down. In both cases, the man is opening his mouth, but what comes out is different. If a person says one thing and later says the opposite, we say that the person is blowing hot and cold.

    "Is Felicia going to try out for the soccer team this year?" Stacy asked.

    "I don't know," Tricia replied." Last week she was saying yes, but this week she's saying no. She's really blowing hot and cold."

Break the ice

    Nowadays people use the phrase to refer to ending an awkward silence by beginning a conversation.

    It was the first day of summer camp. The four girls began to make their beds in silence. None of the girls knew each other, and no one knew what to say. Finally, one of them broke the ice by saying" Hey, where's everybody from?"

Bury the hatchet

    In native American culture, when two nations agreed to end their war, they buried the hatchet. So to bury the hatchet is to make peace with someone else.

Colin could not excuse his sister for breaking his tennis racket. Finally, his sister said, "Colin, can't we bury the hatchet?"

    You're in a department store and you see a couple of attractive young women looking at a sweater．You listen to their conversation：

    “I can't believe it－Lorenzo Bertolla! They are almost impossible to find．Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome．”

    They leave and you go over to see this incredible sweater．It's nice and the price is right．You've never heard of Lorenzo Bertolla, but those girls looked really stylish．They must know．So, you buy it．You never realize that those young women are employees of an advertising agency．They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes．

    Every day we notice what people are wearing, driving and eating．If the person looks cool, the product seems cool, too．This is the secret of undercover marketing．Companies from Ford to Nike are starting to use it．

    Undercover marketing is important because it reaches people that don't pay attention to traditional advertising．This is particularly true of the MTV generation－consumers between the age of 18 and （3）It's a golden group．They have a lot of money to spend, but they don't trust ads．

    So advertising agencies hire young actors to “perform” in bars and other places where young adults go．Some people might call this practice misleading, but marketing executive Jonathan Ressler calls it creative．“Look at traditional advertising．Its effectiveness is decreasing．”It is true, because everyone knows an ad is trying to persuade you to buy something．However, you don't know when a conversation you overhear is just a performance．

    Last week the British university system offered a record number of places. That sounds like good news—but do we really need more people to go to university? For that matter, does the world need more universities?

    The answer feels like it should be yes.

    Education is good, is it not? But everything has a cost.

    Education takes time. We could insist that everyone study full-time until the age of 45 but that would surely be too much. And perhaps half the population studying until they're 21 is also too much. As for universities, they consume financial and intellectual resources—perhaps those resources might be better spent elsewhere.

    My own personal opinion is strongly in favor both of going to university, and of simply having universities around.

    The main skill I learnt at university was to write about economics, and I use that skill every day of my professional life, even an abstract education seems practical to me. And I now live in Oxford, one of the world's most celebrated (著名的) university cities. Oxford's experience certainly suggests that universities have much to offer.

    The city's architecture and green spaces have been shaped—greatly for the better, on balance —by the 900-year-old institution at its heart. The beauty attracts tourists and locals too.

    But these are samples of one. Many people do not find themselves using the skills and knowledge they accumulated at university. And Oxford's dreaming spires (尖顶) aren't terribly representative of global universities as a whole.

    Six months after a Chinese scientist was widely condemned for helping to make the world's first gene­edited babies, he remains out of public view, and new information suggests that others may be interested in undertaking the same kind of work outside the United States.

    A clinic in the United Arab Emirates city of Dubai emailed scientist He Jiankui to seek training in gene editing, Stanford University bioethicist Dr. William Hurlbut said ahead of a speech Tuesday at the World Science Festival in New York.

    Hurlbut, whose advice He often sought, said He told him that scientists from multiple countries and families with inherited health problems had messaged support and interest in altering the genes of embryos(胚胎)to prevent or treat disease. Hurlbut gave The Associated Press the email the Dubai clinic sent to He in December but decided to hide the clinic's name.

    "It reveals what eagerness there is out there to use this technology" and the need "for some sort of practical governance" of it, Hurlbut said.

    Jennifer Doudna, a University of California, Berkeley, co­inventor of the CRISPR gene­editing tool that He used, said that she also has heard of others who want to edit embryos.

    "I think they're entirely credible," she said of such reports. Doudna, who was also a speaker at the New York festival, said the field needs to focus on setting specific principles for how and when such work should proceed.

    "The technology is frankly just not ready for clinical use in human embryos," although research should continue, she said. Doudna is paid by the Howard Hughes Medical Institute, which also supports AP's Health and Science Department.

    Scientists and policy leaders have been debating how to set international standards or controls since He claimed in November that he had altered the genes of twin girls at conception(怀孕)to try to help them resist possible future infection with the AIDS virus.

    Editing embryos is outlawed in many countries because it risks damaging other genes, and the DNA changes can be passed to future generations. Many scientists have condemned He's work, and attention has fallen on other scientists who knew or strongly suspected what He was doing.
