Dear Sir,
I have learned that some volunteers are wanting in our School English Association. So I am eagerly to be one of them to introduce Chinese culture for students from other countries. Meanwhile, it is a good chance for me to learn the school life at my age in western countries.
As an excellent student, among the top 5 in my class, I am good at the English, especially speaking English, which makes easy for me to communicate with students from foreign countries. What’s more, last year my family receive an exchange student as a host family, which gave me a chance to get some relevant experiences. So I’m sure as I’m equal to the job.
I’m looking forward to hearing from you.
Yours,
Li Hua

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.
