1. But science may have just proved them right – because beautiful women are more likely(可能的) to have daughters than those who are ordinary-looking, according to a study.
As parents often pass on genes(基因) that determine(决定) looks, this could result in fewer handsome men on the ground. 2. For example, Yasmin Le Bon is signed to the same modelling company as daughter Amber, and Jerry Hall’s daughters Elizabeth and Georgia Jagger have both taken to the catwalk.
Dr Satoshi Kanazawa, of the London School of Economics, surveyed( 调查 ) 17,000 babies born in Britain in March 1967 and followed them throughout their lives. 3. When they reached 45, they were asked about the gender(性别) of any children they had.
Those considered to be attractive have the same chance to have a son or daughter as their first child –but the unattractive ones were more likely to have a son. 4.
A previous study of 2,000 Americans suggested that women are becoming more beautiful over the generations because attractive women have more children than unattractive ones – and a higher percentage of their children are girls.
Dr Kanazawa believes that parents are more likely to produce children who benefit( 得益) from their own features. 5. So it pays for attractive women to have daughters. But couples with strength and aggression rather than looks are better off having boys, as these characteristics are of more use to males.
A. Famously good-looking parents like Tom Cruise and Katie Holmes are more likely to have girls than uglier couples.
B. Single girls have always complained that good-looking men are difficult to find.
C. Beauty is of more benefit to a woman than a man.
D. At the age of seven, their attractiveness was rated(评估) by their teachers.
E. In other words, beautiful women were more likely to have daughters than unattractive ones.
F. And it may also explain why many models have daughters who follow them.
G. Women are becoming more beautiful over the generations because attractive women have more children than plain ones．
Researchers at the University of Chicago have trained an artificial intelligence( 人工智能) system, to write fake( 伪 造 的 ) reviews( 评 论 ) on Yelp, a website showing customers reviews on shopping or something else, and it's pretty hard to tell them apart from a human review.
Their study, which will be presented at the ACM Conference on Computer and Communications Security in October, aimed to throw attention onto how easily these systems can write reviews like humans and how damaging they can become if they’re not monitored properly.
Since many small businesses depend on online reviews to help grow and keep their reputation, a future where someone—like a rival or angry customer—could crazily fill their page with negative reviews written by a machine is pretty worrying.
And, according to the research team, the threat goes far beyond fake reviews on Yelp. “In general the threat is bigger,” Ben Y. Zhao, one of the authors of the study, said. “I think the threat towards society is large and it really misleads users and shakes our belief in what is real and what is not. I think that' s going to be even unimaginable.”
To test how believable these reviews are, the researchers invited 40 volunteers and had AI make five fake reviews for 40 actual restaurants. The volunteers were asked how useful they thought the review was and whether or not they thought it was fake. The AI reviews was regarded as “effectively unrecognizable ” from real reviews，according to the study. Further, the fake reviews were given a 3.15 "usefulness" rating, compared to a 3.28 rating for human reviews.
1.What can the new artificial intelligence system do according to the passage？
A. It can help train new reviewers.
B. It can tell the real reviews from the fake ones.
C. It can write human-like reviews.
D. It can easily damage the businesses.
2.What does the underlined word "rival'' mean in the passage?
A. A person who respects you deeply.
B. A person who is against you.
C. A person who loves to give fake reviews.
D. A person who can control you from distance.
3.What can we infer from Ben Y. Zhao's remarks?
A. Artificial intelligence can put the society in danger.
B. The artificial intelligence is only used by the researchers
C. Ben Y. Zhao is optimistic about the further development of artificial intelligence.
D. The artificial intelligence will help people shake.
4.What is the best title for the passage?
A. Tips on Giving Reviews. B. How to Tell the Fake Reviews.
C. Development of AI in Review on Yelp. D. AI is coming to Steal Your Reviews.
When it comes to generation gap ( 代沟), we usually think of different tastes in music, or games. But now the generation gap is handwriting. After one teacher in Tennessee discovered that she had students who couldn't read what she was writing on the board, she posted it on the Internet saying that handwriting should be taught in schools.
Others who are against it argue that handwriting has become out of time in our modern world. Typed words have become a main form of communication. Once a practical skill, handwriting is no longer used by most of Americans. It is no longer taught in schools, and some claim that the time that it would take to teach it could be put to better use, for example, by teaching the technical skills.
But even in today's world there are still plenty of reasons to pick up a pen and write on the paper. In America, signatures (签字) by hand are still often requested, for example, signing for a registered letter and buying a house. And original signatures are much more difficult to fake (伪造).
There is also strong evidence that writing by hand is good for the mind. It makes a different part of the brain active and improves fine moving skills in young children. People are also more likely to remember what they write by hand than what they type, and the process of writing by hand has been shown to stimulate ideas. Not only those, studies have shown that kids who write by hand learn to read and spell earlier than those who don't.
Yes, we live in a modern world, but we live in a modern world of basic and important values.
1.What did the teacher find in her class?
A. Her students were too lazy to follow her class. B. Her handwriting was too terrible to understand.
C. There was something wrong with some students’ eyes. D. Some students could not recognize her written words on the board.
2.Some people are against handwriting teaching because they think ________.
A. technical skills are more important than handwriting. B. handwriting is no longer used in society
C. it's difficult to fake typed signatures D. nobody can practice good handwriting in school
3.How many advantages does handwriting have for the mind?
A. 3 B. 4
C. 7 D. 8
4.The underlined word“stimulate”in Paragraph 4 probably means_________.
A. cause B. collect
C. exchange D. influence
Louis Armstrong was born on 4th July in New Orleans, Louisiana. He grew up without a father and he and his sister were raised by his grandmother. When he was 11, Louis dropped out of school. He formed a quartet with three other boys, and they sang in the streets to earn money.
He also used to get into trouble. He was put into prison and sent to live in a home for troubled boys. He talked the band director into letting him join the band, and that’s where he learned to play the cornet (短号), an instrument very much like the trumpet (喇叭).
Louis Armstrong became one of the greatest jazz cornet players that ever lived. He was also an accomplished composer and singer. His nickname was originally “Satchel-mouth”, because some people said his mouth was like a satchel (挎包) where he could hold so much air to blow the trumpet. But one day someone called him “Satchmo” instead of “Satchel mouth”. Louis liked it, and the name stuck. Louis became famous for playing the cornet in clubs and on riverboats.
He was best known for his ability to improvise, which means to make up music as he plays it. He also sang “scat”, which was a style of music in which the singer sings meaningless words instead of real lyrics. Over his career, Louis played in many recordings, and appeared in television shows and movies.
