【題目】D

Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee.

U.S. biochemist Ben Yu has created `Sprayable Energy,` which claims to be the world`s first caffeine - based topical energy spray.He said tired workers can spray a `shot` of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee.

The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee.

Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe.The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure.Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup.

The website said: `The reason for this is our product not being ingested, isn`t almost entirely metabolised（新陳代謝） by the liver before entering your system and becoming available to your body.`

`Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee.`c`s website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day.

It claims that after spraying the product on the skin, users will feel `awake and focused without being over-stimulated,` which is common with coffee and energy drinks.

【1】What can we learn about Sprayable Energy from the passage ?_______.

A.A bottle of Sprayable Energyis cheaper than 40 cups of coffee. .

B.Sprayable Energy lets users not worry about taking in unnecessary calories..

C.Sprayable Energy can be used at least 20 sprays a day

D.The caffeine spray is a colorless liquid that is absorbed through the skin..

【2】What does the fifth paragraph mainly tell us ?____

A,Sprayable Energy is taken by mouth...

B.Before Sprayable Energy is absorbed by body, the liver entirely metabolizes it

C.How Sprayable Energy acts on user’s body and how users use the product.

D.Sprayable Energy is convenient but expensive.

【3】We can conclude from the passage that ____

A.Sprayable Energy can not be permitted to be used by people now.

B. Sprayable Energy has not already gone into mass production

C.each spritz of Sprayable Energy has the same effect as a full cup of coffee

D.Sprayable Energy is well received by flagging workers.

【4】The writer’s attitude towards Sprayable Energy ____

試題分析：這篇文章主要介紹了一種具有咖啡的提神功效的快速提神制劑，又稱為“能量噴霧劑”。

【1】細(xì)節(jié)題。由第二段中的He said tired workers can spray a `shot` of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee.句意為這位化學(xué)家說，工作疲憊的人可以直接用它在皮膚上“來一發(fā)”咖啡因，無需受到咖啡機(jī)嗡嗡聲的折磨，不用擔(dān)心攝入過多卡路里，也不會(huì)在喝完咖啡或其他能量飲料后嘴里出現(xiàn)難聞的味道可以推斷出，故選B。

【2】大意概括題。由第五段中的The reason for this is our product not being ingested, isn`t almost entirely metabolised（新陳代謝） by the liver before entering your system and becoming available to your body.website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day.句意為之所以這樣說，是因?yàn)槲覀兊漠a(chǎn)品無需口服，咖啡因在進(jìn)入人體循環(huán)系統(tǒng)為你所用之前，不會(huì)參與肝臟負(fù)責(zé)的新陳代謝。能量噴霧網(wǎng)站還建議使用者把咖啡噴霧噴在普通香水的作用位置，比如脖子和手腕，但警告使用者一天噴霧不要超過20次以上可以推斷出，故選C。

【3】推斷題。由第五段中的but warns users not to exceed 20 sprays a day.句意為但警告使用者一天噴霧不要超過20次以上可以推斷出該產(chǎn)品不能大量使用，因此還沒有大量生產(chǎn)，故選B。

【4】推斷題。由最后一段中It claims that after spraying the product on the skin, users will feel `awake and focused without being over-stimulated,` which is common with coffee and energy drinks.句意為網(wǎng)站聲稱，當(dāng)噴霧作用于皮膚上時(shí)，使用者會(huì)感到“清醒專注而不會(huì)過度興奮”，正是咖啡和能量飲料通常具備的效果可以推斷出該噴霧具有咖啡等飲料的提神功效，且使用更方便，因此作者持支持態(tài)度，故選B。

【題目】Boys' schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music.

Far from the traditional image of a culture of aggressive masculinity (陽剛), the absence of girls gives boys the chance to develop without pressure to conform to a stereotype, a US study says.

Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to conform to the "boy code" of hiding their emotions to be a "real man".

The findings of the study go against received wisdom that boys do better when taught alongside girls.

Tony Little, headmaster of the British boys-only school, Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.

The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills.

But in single-sex schools teachers can tailor lessons to boys' learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia.

Teachers could encourage boys to enjoy reading and writing with "boy-focused" approaches such as themes and characters that appeal to them. Because boys generally have more acute vision learn best through touch, and are physically more active, they need to be given "hands-on" lessons where they are allowed to walk around, James found.

Single-sex education also made it less likely that boys would feel they had to conform to a stereotype that men should be "masterful and in charge" in relationships. "In mixed schools boys feel compelled to act like men before they understand themselves well enough to know what that means, " the study reported.

A. forces boys to hide their emotions to be "real men”

【2】It is commonly believed that in a mixed school boys __________.

A. It fails more boys than girls academically.

B. it focuses more on mixed school education.

C. It fails to give boys the attention they need.

D. It places more pressure on boys than on girls.

【4】According to Abigail James, one of the advantages of single-sex schools is __________.

A. teaching can be tailored to suit the characteristics of boys

B. boys can focus on their lessons without being distracted

C. boys can choose to learn whatever they are interested in

D. teaching can be designed to promote boys' team spirit

【5】Which of the following is characteristic of boys according to Abigail James' report?

【題目】C

A machine that takes sweat-laden clothes and turns the moisture into drinking water is in use in Sweden.The device spins and heats the material to remove the sweat, and then passes the vapor through a special membrane designed to only let water molecules get through.

Since its Monday launch, its creators say more than 1,000 people have "drunk other's sweat" in Gothenburg.They add the liquid is cleaner than local tap water.

The device was built for the United Nation's child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.

The machine was designed and built by engineer Andreas Hammar, known locally for his appearances on TV tech show Mekatronik.He said the critical part of the sweat machine was a new water purification component developed by a company named HVR in collaboration with Sweden's Royal Institute of Technology.

"It uses a technique called membrane distillation(膜蒸餾)," he told the BBC."We use a substance that's a bit like Gortex that only lets steam through but keeps bacteria, salts, clothing fibers and other substances out."They have something similar on the International Space Station to treat astronaut's urine - but our machine was cheaper to build.Volunteers have been sampling the treated sweat since the start of the week in Gothenburg"The amount of water it produces depends on how sweaty the person is - but one person's T-shirt typically produces 10ml , roughly a mouthful."

The equipment has been put on show at the Gothia Cup - the world's largest international youth football tournament.MattiasRonge, chief executive of Stockholm-based advertising agency Deportivo - which organized the stunt(驚人的表演) - said the machine had helped raise awareness for UNICEF, but in reality had its limitations.

"People haven't produced as much sweat as we hoped - right now the weather in Gothenburg is lousy," he said."So we've installed exercise bikes alongside the machine and volunteers are cycling like crazy."Even so, the demand for sweat is greater than the supply. And the machine will never be mass produced - there are better solutions out there such as water purifying pills."

【1】Which of the following is the disadvantage of the machine?_______.

A.The water processed by the machine is cleaner than local tap water .

B.The amount of water the machine produces is too small.

C.the machine is cheaper than the similar one on the International Space Station

D.The machine can help raise awareness of lacking water in the world .

【2】What is the main idea of the fifth paragraph ?

A.How the machine works.

B.Who developed the machine.

C.How the machine was invented.

D.Why the machine was invented..

【3】What does Mttias Ronge think of the machine?____

A.The machine can solve the severe water shortage in the world..

B.People do not like the water the machine processes

C.The machine should be used in rather hot areas in summer.

D.The machine is not worth popularizing..

【4】The passage is most likely to be____

A.a tourist brochure.

B.a book review

C.a news report

D.a blog.

【題目】A

THE TRIP OF A LIFETIME

In June 1971, Helene Hanff travelled to London and visited the site of Marks & Co, the bookshop that had been dear to her for 20 years. While Hanff was very happy to finally step foot on British soil the visit carried with it a sad irony (諷刺), which she explained in a 1980 television interview with Dick Cavett: “It was very sad,” she said. “It was the bookstore manager Frank Doel’s death that made me want to write the story of our correspondence and when a publisher bought it, I went to London on the proceeds of the sale.”

Hanff spent the early part of her career trying to make a name for herself as a playwright. London-based writer Monica Porter, who met her in the 1980s, says that Hanff considered herself a “failed playwright” and that her 1961 book Underfoot in Show Business was an account of her failure to get her plays produced. A decade after 84, Charing Cross Road was published, James Roose-Evans adapted the book for the stage and the play was a West End hit.

It had a 16-month run and Hanff finally got to taste stage success, albeit (雖然；即使) in a circuitous (迂回的) way. In a piece that Porter wrote for the British weekly newspaper, The Stage, she says Hanff was led on stage at the end of the opening night performance to thunderous applause. “To get a standing ovation(熱烈的鼓掌) like that, taking curtain calls before an enthusiastic audience, was something she must often have dreamt about,” Porter wrote.

The stage adaptation opened in the US a year later, but never lived up to its West End success. This was to Hanff’s great relief. According to Porter, she once recounted: “Being a celebrity for a week in London had been the most fun I’d had in my life, and wonderful for the ego (自我) - but only because I’d known I was coming home at the end of it, home to the quiet, orderly, solitary(獨(dú)立的), unglamorous life I was made for.”

However, her peace was not to last: Hollywood came calling. The 1987 film of 84 Charing Cross Road, produced by Mel Brooks, won several awards.

Anne Bancroft starred as Hanff. Doel was played by Anthony Hopkins. Hanff died in New York in 1997 from diabetes-related complications. Today, the Marks & Co building is a restaurant with a plaque on its street frontage that commemorates(紀(jì)念) the author that made the site so famous. And Hanff’s unlikely bestseller remains in print.

【1】What made Helene Hanff want to write the story of their correspondence?

A. The trip to the bookstore.

B. The death of the bookstore manager.

C. A decade after 84, Charing Cross Road was published.

D. Visiting the site of Marks & Co, the bookshop.

【2】It took Hanff the early part of her career to _______.

A. finally step foot on British soil

B. commemorate the author that made the site so famous

C. try to make a name for herself as a playwright

D. get to taste stage success

【3】What made Hanff feel relieved?

A. The stage adaptation that never lived up to its West End success.

B. The 1987 film of 84 Charing Cross Road winning several awards.

C. James Roose-Evans adapting the book for the stage.

D. A piece that Porter wrote for the British weekly newspaper, The Stage.
