15.A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate.An analysis of 36 months of detailed taxi,driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis.The higher visibility (能见度) of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis,leading to a lower accident rate.
The study was led by Prof Ho.To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had,the research team analysed data collected by the largest taxi company in Singapore.The researchers found that yellow taxis have about 6.1 fewer accidents per 1,000 taxis per month.
They also studied the economic effect of changing the color of the entire fleet of taxis to yellow.The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis.If a commercial decision is made to switch from blue to yellow taxis,76.6 fewer accidents will occur per month or 917 fewer accidents per year.
Assuming an average repair cost of﹩1,000 per car and a downtime of six days,the color of all taxis to yellow could produce an annual saving of﹩2 million.
"We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport,such as school buses.For example,we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses.Besides,we're also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.

32.Why do yellow taxis result in fewer accidents?B
A.Because yellow signals a warning of danger.
B.Because yellow can be seen more easily.
C.Because drivers tend to he more careful in yellow taxis.
D.Because people act more quickly in yellow surroundings.
33.What's Prof Ho's study based on?D
A.Physical risks taxi passengers experience.
B.The economic effect of changing taxi color.
C.Personal reports from taxi drivers worldwide.
D.Data from Singapore's largest taxi company.
34.What do Prof Ho's words in the last paragraph suggest?C
A.School buses should be painted yellow.
B.Their findings are worth popularizing.
C.Their study will be furthered.
D.Yellow should be widely used in public transport,
35.What can be the best title for the text?A
A.Safer to ride in yellow taxis
B.Caution:yellow taxis ahead
C.Why are yellow Taxis preferred?
D.How can colors help prevent accidents?

分析 本文向我们讲述了新加坡一项研究表明,黄色出租车比蓝色出租车更安全,因为黄色车身的可见度更高,从而减少了事故发生率.

解答 32.B;细节理解题;根据文章第一段最后一句"The higher visibility of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis,leading to a lower accident rate"可知黄色出租车造成的事故更少是因为黄色的能见度更高.故选B.
33.D;细节理解题;根据文中第二段的"To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had,the research team analysed data collected by the largest taxi company in Singapore"可知Prof Ho领导的团队是通过分析,研究新加坡最大的出租车公司提供的数据得出的结论.故选D.
34.C;推理判断题;根据Prof Ho在文章最后一段中所说的"We are eager to continue to validate the findings of our study…we are also interested to…"可推知,他们将继续验证研究结果并对不同颜色车辆的事故率做一个对比.故选C.
35.A;主旨大意题;通读全文可知,本文主要讲新加坡的一项研究成果:黄色出租车引发的事故率更低.由此可知,"乘坐黄色出租车更安全"最适合作本篇文章的标题.故选A.

点评 本文考察学生的细节理解和推理判断能力以及细心程度,只要抓住文章的关键词,采用寻读的方法查找细节,就能找到正确答案.

4.Many studies have shown that students learn in different ways and that good results can be achieved if they are taught by a teaching method that suits them best.Similarly,students'performance varies in what types of test they are given.Therefore,it may seem reasonable to give students the chance to choose how they wish to be tested.However,this would mean teachers would be forced to prepare many different methods of assessment for the exact same material.Teachers are already very busy,creating tests,grading,coming up with interesting lesson plans,teaching classes,not to mention holding parent teacher conferences,and creating new tests would only add to their burden.
Another strain teachers would have to face is how to grade fairly and objectively if students were tested on the same material in a variety of ways.For instance,how do you compare a student who wrote an essay on one small topic of a book to another who answered every multiple choice question correctly over the entire book?Maybe the student who wrote the essay only read a small part of it in depth enough so that they could write the essay.But perhaps the student taking the multiple choice test only had a base understanding of the book and couldn't write a critical essay about something in it.
This is not to say,however,that students should be graded in the same manner every time.This would be equally unfair as again,different students test better when assessed by different methods.Therefore,teachers need to be sure to give essay tests,multiple choice tests,as well as other multi-media(多媒体) projects to assess their students,just not over the same material.This gives students the opportunity to show off their abilities and make up for tasks that they're not good at.For instance,a student that is a bad test taker could make up for their grade with a well-performed project.Another option is to provide students with extra credit opportunities.As such,students could be allowed to choose the method in which they wish to complete their extra credit.If a student is a strong essay writer,they could write an extra essay to make up for their poor test grade.This would allow students to compensate for poor grades in areas in which they aren't as accomplished.

32.We know from Paragraph 1that if students could choose how they are tested,teachers wouldA.
A.have more work              
B.lose their authority
C.change their lesson plans          
D.prepare more testing materials
33.What does the underlined word"strain"in Paragraph 2 mean?B
A.Possibility.
B.Difficulty.
C.Approach.
D.Hesitation.
34.The author writes the last paragraph in order toA.
A.offer suggestions           
B.draw a conclusion
C.predict the future           
D.prove his point
35.Where is the text most probably taken from?D
A.A science book.
B.An announcement.
C.A news report.
D.An education magazine.

3.As reported by The Times on July 12,half of primary schools in the UK will soon adopt the traditional Chinese method of maths teaching in a Government drive to stop British children falling behind those in Asian.They will get rid of"child-centered"styles and instead return to repetition,drills and"chalk and talk"whole-class learning.Teachers will be offered training,textbooks and advice on how to adopt the Shanghai maths method.
Children in the UK are far behind those in China,Singapore and Japan in international league tables of numeracy(计算能力).Critics blame"progressive"teaching styles that focused on applying maths to real-life scenes in an effort to make the subject more interesting.They say this has led to confusion and stopped children learning the basics.
Under the Government's new plans,children as young as five will have drills to practise sums and exercises,and must master each concept through repetition before moving to the next.Nick Gibb,the schools minister,said that training would be provided for 8,000 primary schools-half the country's total-to switch to the Shanghai‘mastery'approach."We are seeing a renaissance(复兴) in maths teaching in this country,with good ideas  from around the world helping to make our classrooms more lively,"he said,"I am confident that the steps we are taking now will make sure young people are properly prepared for further study and the 21st-century workplace,and that the too often heard phrase‘can't do maths'is abandoned to the past."He has promised£41million to provide textbooks and training for two teachers from each participating school.
But some teaching leaders questioned whether the success of Asian countries was purely down to the style of lessons.James Bowen,director of NAHT Edge,a union for middle school leaders,said:"Part of the success of maths teaching in countries like China comes from the respect in which they hold teachers and the time they give them to plan and prepare.If the Government wanted to import these practices,too,we wouldn't object."

24.What is the passage mainly about?C
A.China has better approaches to teaching maths than Britain.
B.Practice and repetition play an important part in learning maths.
C.Chinese maths teaching methods will come into British primary classrooms.
D.The British government attaches great importance to education.

C.Objective
D.Supportive

Start small with people you know.Practise social behavior like eye contact,confident body language,introductions,small talk,asking questions,and invitations with the people you feel most comfortable around.Build your confidence this way.(36)B
Think of some conversation starters.(37)EThink of conversation openers,like introducing yourself,giving a compliment,or asking a question.Being ready with a conversation starter (or a few) makes it easier to approach someone.
Rehearse (排练)what you want to say.(38)D Practise it again and again,maybe even in front of a mirror.Then just do it.Don't worry if it's not exactly like what you practised or if it's not perfect.Few of the things more confident-seeming people do are perfect either.Next time,it'll be even better because it will be easier.

7.A handshake is one of the most common ways to greet others,but US President Donald Trump's unusual method has been put under the microscope lately.
Much like an armwrestler in a match,the recently-elected leader has a habit of yanking (猛拉) people's hands toward himself during handshakes.And while a typical handshake is only brief,the one between him and Japanese Prime Minister Shinzo Abe on Feb 10 lasted a full 19 seconds.
Simply having a strong hand is not the explanation here.According to Darren Stanton,a body language expert from the UK,while handshakes are usually an exchange of kindness,Trump uses his as a way to show power and control,regardless of how uncomfortable it makes people."It is as if to say,‘Hey,I'm in charge,don't mess with me,'"Stanton told The Independent.
Apart from Trump's"yank-shake",there are other ways people display power with their hands.At business talks or political meetings,for example,some people may rotate (旋转) their wrists during handshakes so that their hand ends up on top instead of underneath.Some may squeeze so hard that it leaves the other person's hand in pain.
According to Stanton,by pulling people into his personal space,Trump is also testing w hether they are willing to cooperate with him."For example,if someone was resistant to being yanked towards him and stood their ground,he would know that he has work to do with them before he got what he wanted,"Stanton told Express.
This is probably why on Feb 13 when Canadian Prime Minister Justin Trudeau visited the White House,all eyes were on how he was going to handle Trump's handshake.Fortunately,Trudeau managed to avoid the embarrassment by grabbing Trump's shoulder to stop himself being pulled in.Afterward,some Twitter users wrote that this proved Trudeau's strong leadership,with one even calling the moment"one of Canada's greatest victories".
Vice magazine summed up the exchange between the two leaders as:"…no regular handshake.This was the first shot in a bloodless war."

25.According to Darren Stanton,Trump uses his"yank-shake"toA.
a.show his kindness              
b.gain control         
c.remind people of his status
d.see if people are cooperative    
e.get people to lower their guard
A.bcd
B.abc
C.ace
D.bde
26.The phrase"stood their ground"in Paragraph 5 probably meansB.
A.going ahead
B.standing still     
C.turning around  
D.pulling out
27.According to the text,the way Trudeau reacted to Trump's handshakeB.
A.annoyed Trump         
B.displayed his power
C.was considered rude          
D.was likely to start a war
28.What can be concluded from the text?C
A.Some people spin their wrists during handshakes to show extra respect.
B.Handshakes are the most preferable way for political leaders to greet others.
C.The way someone shakes another person's hand can have different meanings.
D.The longer two people shake their hands,the better their relationship is.
