　　(2015·江淮十校联考)Older fathers have uglier children, researchers have claimed after linking age to genetic mutations(变异)．

　　The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism and mental disorders.

　　With age, sperm(精子)­producing cells do not copy a man's DNA as effectively, leading to genetic mutations.

　　Martin Fielder, an anthropologist(人类学家) at Vienna University, told the Sunday Times: Every 16 years the mutation rate doubles. Other researchers found 25 mutations per sperm in a 20­year­old, but at age 40 it is 65 mutations. By 56, it doubles again.

　　The effect is very visible—someone born to a father of 22 is already 5­10 per cent more attractive than those with a 40­year­old father and the difference grows with the age gap.

　　In contrast, women pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature.

　　Surveying a group of six men and six women, researchers showed them each 4,018 photographs of 18­20­year­old men and 4,416 of women the same age, and asked to assess their attractiveness.

　　Those with older fathers were consistently considered less attractive.

　　However, the children of older men, though less attractive, are likely to outlive their peers with younger fathers, it is claimed.

　　Professor Lee Smith, a geneticist at Edinburgh University, told the Sunday Times other research found such children have longer telomeres(端粒)—the caps on the end of chromosomes(染色体)—which are associated with longer life.

　　But the mounting research connecting parents' age with autism is cause for concern, experts warn.

　　Autism is an umbrella term for a range of developmental disorders that have a lifelong effect on someone's ability to interact socially and communicate openly.

　　In the UK, around one in 100 adults is thought to be affected by autism, mostly men, caused by a combination of genetic and environmental factors.

　　Researchers said men should be advised about the potential problems in order to help their personal decision­making when it came to having fathering children at older ages.

　　They warned that advancing paternal age faced a risk of ‘numerous public health and societal problems’．

　　Among well­known older dads are Simon Cowell, 54, whose son was born earlier this month, and comedian Frank Skinner whose first child was born in 2017 when he was 55.

　　[语篇解读]　文章主要介绍了科学家的最新发现——年龄大的父亲生的孩子丑的可能性更大。

　　What the school of the future will be like is unknown, but most educators and observers agree that the future school will go electronic with a capital E.

　　“This century, schools as we know them will no longer exist，” says a feature in The Age publication, based in Melbourne, Australia. “In their place will be community­style centers operating seven days a week, 24 hours a day.” Computers will become a necessary part for an effective school of the future.

　　Students, The Age says, will see and hear teachers on computers, with “remote learning”， the trend of tomorrow. Accessing “classrooms” on their home computers, students will learn at times most convenient for them. Yet some attendance at an actual school will be required to help students develop right social skills.

　　At Seashore Primary School, an imaginary school of the future created by the Education Department of Australia, technology is the thing that holds classes together. At the imaginary Seashore school：

　　◆all teachers and students have laptop computers.

　　◆teachers check voicemail and return students' calls on a special telephone system.

　　◆students use telephones to find information or speak to experts in subject areas they are studying.

　　◆all lessons are multidisciplinary.

　　◆all students have individual learning plans created by teachers.

　　As Seashore's acting headmaster says, a laptop computer is the students' “library, homework, data storage, and connection to the wider world. Technology has changed the emphasis(重点)to the learning of kids rather than the teaching of kids. ”

　　[语篇解读]　文章主要说明现在的学校模式在未来将不复存在，以及想象未来学校的样子。

　　5．

　　will be very popular in the future.

　　A．Classroom learning

　　B．Internet learning

　　C．Telephone learning

　　D．Remote learning

　　【解析】　细节理解题。从原文第三段中的“‘remote learning’， the trend of tomorrow”可知“远程学习将成为将来的流行趋势”。

　　【答案】　D

　　6．In the future, students should go to school sometimes to

　　.

　　A．hand in their homework

　　B．have an examination

　　C．develop right social skills

　　D．discuss problems with their teachers

　　【解析】　细节理解题。即使将来学生们可以在家学习，但有时还必须去现实生活中的学校去接受正确的社交技能的培养。这从原文第三段末的“Yet some attendance at an actual school will be required to help students develop right social skills.”可知。

　　【答案】　C

　　7．By saying “students will learn at times most convenient for them”， the writer means that

　　.

　　A．students can learn whenever they like best

　　B．students can learn only when their teachers are free

　　C．students have no right to choose when to learn

　　D．the teachers will begin their classes when the students are not busy

　　【解析】　细节理解题。要正确理解此句，首先要知道them指的是前面的students，而不是teachers，可排除D项。另外，此句中的most convenient for them作定语修饰times。此句意为“学生们将会在他们最方便的时候学习”，故A项正确。

　　【答案】　A

　　8．From the passage we can learn that

　　.

　　A．Seashore Primary School is a famous school situated in Melbourne

　　B．students will do their homework on the computers in the future

　　C．students have the same learning plans made by their teachers

　　D．students will have lessons from Sunday to Saturday

　　【解析】　推理判断题。根据原文最后一段a laptop computer is the students' “library, homework. . .”可知“笔记本电脑是学生的图书馆、家庭作业、数据存储器，以及与更广阔世界的联系(纽带)”，因此B项正确。根据原文第四段开头可知Seashore Primary School是所imaginary school(虚拟学校)，故A项不正确。根据“all students have individual learning plans created by teachers”可知学生们均有老师为他们制订的个人计划，故C项不正确。虽然未来的学校是全日制的，但由于学生们可以在他们最方便的时间学习，所以他们就不必天天上课了，故D项不正确。

　　【答案】　B

　　Ⅳ.阅读填句

　　Empathy

　　Last year, researchers from the University of Michigan reported that empathy, the ability to understand other people, among college students had dropped sharply over the past 10 years.

　　1

　　Today, people spend more time alone and are less likely to join groups and clubs.

　　Jennifer Freed, a co­director of a teen program, has another explanation. Turn on the TV, and you're showered with news and reality shows full of people fighting, competing, and generally treating one another with no respect.

　　2

　　There are good reasons not to follow those bad examples. Humans are socially related by nature.

　　3

　　Researchers have also found that empathetic teenagers are more likely to have high self­respect. Besides, empathy can be a cure for loneliness, sadness, anxiety, and fear.

　　Empathy is also an indication of a good leader. In fact, Freed says, many top companies report that empathy is one of the most important things they look for in a new managers.

　　4

　　“Academics are important. But if you don't have emotional (情感的) intelligence, you won't be as successful in work or in your love life，” she says.

　　What's the best way to up your EQ (情商)? For starters, let down your guard and really listen to others.

　　5

　　.

　　To really develop empathy, you'd better volunteer at a nursing home or a hospital, join a club or a team that has a diverse membership, have a “sharing circle” with your family, or spend time caring for pets at an animal shelter.

　　A．Everyone is different, and levels of empathy differ from person to person.

　　B．That could be because so many people have replaced face time with screen time, the researchers said.

　　C．“One doesn't develop empathy by having a lot of opinions and doing a lot of talking，” Freed says.

　　D．Humans learn by example—and most of the examples on it are anything but empathetic.

　　E．Empathy is a matter of learning how to understand someone else—both what they think and how they feel.

　　F．Good social skills—including empathy—are a kind of “emotional intelligence” that will help you succeed in many areas of life.

　　G．Having relationships with other people is an important part of being human—and having empathy is decisive to those relationships.
