10、dont show your secret personality when youre awake because you can control yourself,but when youre asleep,your sleeping position shows the real you.In a normal night,of course,you often change your sleeping positions.The important position that best shows your secret personality is the one that you

11、fall asleep with. If you go to sleep on your back,youre a very open person.You normally trust people and you are easily influenced by fashion or new ideas.You dont like to upset people.So you never express your real feelings.Youre quite shy and you arent very confident. If you sleep on your stomach,

12、you are a person who likes to keep secrets.You worry a lot and youre always easily becoming sad.You never want to change your ideas,but you are satisfied with your life the way it is.You usually live for today not tomorrow. If you sleep curled up(卷曲),you are probably a very nervous person.You have a

16、ems. D.Enough sleep makes people look better and healthier. B Dyson has just unveiled its second beauty gadget and its certainly going to make waves in more ways than one.The Airwrap(卷发棒) is the much anticipated follow-up to the Supersonic hairdryer which proved a huge hit despite the 299 cost.This

17、new gadget promises to be a whole new way to create waves and smooth blow-dries,but the price alone is enough to make your hair curl,coming in at an even heftier 399.So what,exactly,is your money buying you? Can there really be THAT different a way to curl your hair? Well,this being Dyson,the answer

18、 is yes.Its radically different from your typical curling irons that involve you physically winding your hair around a scorching-hot barrel.The new Airwrap technology uses jets of air to attract your hair onto the curling barrel,automatically wrapping it and shaping it.All you have to do is place a

19、section of hair close to the styler,and itll wind itself around the styler by a (literally) invisible force. If youre a beauty geek,you might like to know that force has a name the Coanda Effect.This occurs when a high speed jet of air flows across a surface and the difference in pressure makes the

20、air flow (and any hair that gets caught up in its wake) attach itself to that surface.Dyson says the Coanda effect enables you to shape your hair at far lower temperatures than regular styling,which translates into less damage.Like the Supersonic dryer,the Airwrap employs “intelligent heat control”,

21、measuring the temperature up to 40 times a second to ensure the heat never reaches the point where your hair is frazzled to the point of no return. The Airwrap comes with different attachments,depending on the style you want to achieve.You can either go for a wavy look with the curling barrel or use

22、 the Coanda effect to guide your hair onto the brush attachment,replicating a salon style blow dry without the arm ache. “Once my hair was wrapped in place and had been sufficiently whooshed for a few seconds,I hit the cool button to set the style,then slid the styler out of my hair.I felt shocked,p

23、roud,ecstatic,disbelieving.It was kind of like childbirth without the mess.”Then again,many people were initially sceptical about the idea of coughing up nearly 300 for a hairdryer,yet the Supersonic has blown away all the doubters.Whos to say the Airwrap wont be our new best curl friend? The Dyson

24、Airwrap is available at Dyson online and in Dyson stores. 24.Compared with the Supersonic hairdryer,the Airwrap . A.is much bigger B.is more expensive C.couldnt dry hair D.needs more energy 25.What does the underlined sentence mean? A.Is it worth your money? B.Is it what you really want? C.Could it

25、curl your hair? D.Is it affordable for you? 26.What do we know about the Airwrap? A.It does little harm to your hair. B.You need to wind your hair around the styler by force. C.The “intelligent heat control” is unique to the Airwrap. D.The key technology can ensure the temperature high enough to sha

26、pe your hair. 27.How does the customer feel when she uses the Airwrap for the first time? A.Satisfied. B.Disappointed. C.Embarrassed. D.Skeptical. C For Canaan Elementarys second grade in Patchogue,N.Y.,today is speech day,and right now its Chris Palaezs turn.The 8-year-old is the joker of the class

27、.With shining dark eyes,he seems like the kind of kid who would enjoy public speaking. But hes nervous.“Im here to tell you today why you should.should.”Chris trips on the“-ld,”a pronunciation difficulty for many non-native English speakers.His teacher,Thomas Whaley,is next to him,whispering support

28、.“.Vote for.me.” Except for some stumbles,Chris is doing amazingly well.When he brings his speech to a nice conclusion,Whaley invites the rest of the class to praise him. A son of immigrants,Chris started learning English a little over three years ago.Whaley recalls(回想起) how at the beginning of the

29、year,when called upon to read,Chris would excuse himself to go to the bathroom. Learning English as a second language can be a painful experience.What you need is a great teacher who lets you make mistakes.“It takes a lot for any student,” Whaley explains,“especially for a student who is learning En

30、glish as their new language,to feel confident enough to say,I dont know,but I want to know.” Whaley got the idea of this second-grade presidential campaign project when he asked the children one day to raise their hands if they thought they could never be a president.The answer broke his heart.Whale

31、y says the project is about more than just learning to read and speak in public.He wants these kids to learn to boast(夸耀) about themselves. “Boasting about yourself,and your best qualities,” Whaley says,“is very difficult for a child who came into the classroom not feeling confident.” 28.What made C

32、hris nervous? A.Telling a story. B.Making a speech. C.Taking a test. D.Answering a question. 29.What does the underlined word “stumbles” in paragraph 2 refer to? A.Improper pauses. B.Bad manners.

A.Humorous. B.Ambitious. C.Caring. D.Demanding. D We humans love to stare into our smar

34、t devices.We gaze for hoursabout 10 hours and 39 minutes a dayat our computers,smartphones,tablets and televisions.Is all this staring bad for us?It might be,mainly because as we stare at our devices we are exposing ourselves to blue light. Blue light is a type of electromagnetic radiation with a ve

35、ry short wavelength that produces a high amount of energy.While its true that light can damage our eyes under certain circumstances,theres no scientific evidence suggesting that blue light is harmful to our eyes.But many people still think it is,which is why blue light-blocking glasses are so popula

36、r.So,do the glasses work? “Everyone is very concerned that blue light may be causing damage to the eye,but theres no evidence that it may be causing serious damage,” Dr Rahul Khurana,a clinical spokesman,told Business Insider. Blue light exposure is nothing new.In fact,the sun is the largest source

37、of blue light.Moreover,blue light is also present in LED light.But if blue light isnt harmful,then why are we constantly rubbing our eyes when were looking at our screens?The answer is eyestrain(眼疲劳).More than 60 percent of people experience eye problems associated with digital eyestrain.And blue li

38、ght,it seems,isnt the cause.Instead,our eyes are so strained because most of us blink less when we stare at our digital devices.So,if eyestrain is the real issue,blue light-blocking glasses are probably of little use. 32.What do we know about blue light? A.It has the shortest wavelength. B.Its a kin

39、d of nuclear radiation. C.It consumes a great deal of energy. D.It may come from electronic devices. 33.What causes the popularity of blue light-blocking glasses?
