How do you wake up in the morning? Imagine you set an alarm on your phone or clock that goes off like this: beep beep beep. 1. The state is known as grogginess (东倒西歪). So, is there a better way to wake up? A recent study says yes. The answer is music. Researchers say alarms that have a melody can help people feel fresher in the morning.

Sleep inertia (睡后迟钝) is another term for grogginess. 2. Someone even has trouble getting moving again after sleeping. Stuart McFarlane was a lead writer of the study. He said people need to better understand sleep inertia’s harmful effects on human performance later in the day. The grogginess we may feel in the morning has been reported to last from two to four hours.

3. But for those who do, care should be taken when perform duties that require a top performance within this period. 4. The same is true for people like pilots and firefighters. Sleep inertia has been linked to major accidents including airplane and shipping crashes.

What makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a “beeping” alarm. 5.

No matter how you wake up, experts say, the amount of sleep you get also matters a lot.

A.It means a person has a heavy feeling when waking up.

B.This includes dangerous tasks like driving or riding bikes shortly after waking up.

C.That harsh sound may make it harder to shake off the sleepy feeling.

D.Not everyone will experience the full effect.

E.The unpleasant beep is expected to be successful at waking up a person.

F.The changes over time may help increase a person’s attention when waking from sleep.

G.People who wake up to musical alarms feel more awake and alert.

根据短文内容，从短文后的选项中选出能入空白处的最佳选项。选项中有两项为多余选项。

Did you know that if you need an alarm clock to wake up in the morning, you’re probably sleep-deprived （缺失）? __1._______ . On average, American teens get two hours less than the average 9.2 hours of sleep they need each night to function at their best.

There are many reasons why teens don’t get enough sleep. ____2.______ . When your parents were young, they might have read a book or watched television before trying to go to sleep. But today’s teens are likely to be surfing the Internet, texting, emailing, or playing video games right before bed. ___3._____ . And using them right before bed can result in difficulty getting to sleep. According to a survey by the National Sleep Foundation, teens with four or more electronic equipment in their rooms are much more likely than their peers to get an insufficient amount of sleep at night, and are almost twice as likely to fall asleep in school and while doing homework.

___4.______ . In the National Sleep Foundation survey, three-quarters of the teens took　 at least one drink with caffeine every day, and nearly one-third consumed two or more every day. With all the trendy “high-energy” drinks and coffees out there right now, it’s easy to get a caffeine overload and that’s not good for sleep.

So what can you do if you’re in lack of sleep? “The good news is that you only have to make up about a third of what you have lost, to function and feel better,” says Dr. Mahowald at a sleep disorders center. ____5.______ . But sleeping until noon on the weekend can cause problems — you’ll likely be wide-eyed until late those nights. Instead, try keeping a reasonable, regular sleeping and waking schedule.

A. One of them is a relatively new development.

B．Those extra two hours of sleep on Saturday and Sunday mornings can really help.

C．Most teens don’t get enough sleep.

D．Many teens also drink too much caffeine to sleep well.

E．Electronic devices are more exciting than simply watching television.

F．Researchers also have found that biology plays a role in teens’ sleep patterns.

G．Many school districts are shifting their start times to later morning for school students.

IMAGINE if there was a device that could do everything for you – wake you up every morning, chat with you and type your e-mails.

The piece of technology in question would be smart, able to tell you about the weather and where the nearest restaurants are.

The good thing is you no longer need to wonder, because something like this already exists. And its name is Siri.

Siri is a voice recognition application designed for Apple products and the concept has been around for almost a year.

When Siri first came out it could only speak English, but now it has “learned” lots of new languages, including Chinese, Cantonese and Taiwanese, reported The Wall Street Journal. So, you can give it orders in your mother tongue.

But how could a cell phone or a computer “hear” what you are saying and understand it? This is all because of voice recognition technology.

When you speak, your voice creates vibrations (振动) in the air – a bit like waves in the water when you throw a rock into the lake. The microphone receives the vibrations and the computer changes them into digital data that is then divided into many parts. They are analyzed one by one to see what pronunciations each part stands for. The computer then puts these pronunciations together into possible words according to its built-in dictionary.

But figuring out the words is far from enough; building words into meaningful sentences is the most difficult part. The computer has to compare what it hears to a large library of known phrases and sentences to determine what the user is saying.

However, people don’t always talk in the most standard way and sometimes make grammatical mistakes. This is why traditional voice recognition software always requires you to remember keywords and to speak in a certain way.

Fortunately, Siri isn’t like that. It’s not just “voice recognition”; it’s “natural language understanding (NLU)”. You can ask it things like “Do I need an umbrella today?” and it will know that you are asking about the weather, according to ABC News.

“The key thing is NLU – understanding what you mean and what you want,” Neil Grant from Nuance, a software company in the US, told The Guardian. “Historically, you had to learn a huge long list of commands . As NLU progresses, you can say what you want in a way that’s natural to you.”

1.What is the function of the first two paragraphs?

A．To show that invention usually results from need.

B．To clear doubts about voice recognition technology.

C．To introduce something that offers these helpful services.

D．To show how the voice recognition works.

2.Which step is the most complicated in the process of voice recognition according to the article?

A．Changing the received vibrations into digital data.

B．Analyzing the digital data to see what pronunciations it represents.

C．Putting the pronunciations together into possible words.

D．Figuring out meaningful sentences based on the words.

3.How can you get Siri to respond according to the article?

A．You can speak in a natural way as you would to a person.

B．You can only speak English and Chinese.

C．You have to say things in a certain way.

D．You have to remember keywords and speak specific commands.

4.What can be concluded from the article?

A．Siri can record and save what you say frequently into a computer dictionary.

B．Siri will fail to understand what you say if you make grammatical mistakes.

C．The biggest advantage of Siri is that it’s NLU is rather than just voice recognition.

D．Since first applied to Apple products a year ago, Siri has made great improvements.

5.The text is mainly about ________.

A．the convenience of future life.

B．an introduction to the Apple products.

C．the working system of voice recognition

D．the introduction to Siri

高三英语七选五中等难度题查看答案及解析

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 odorless 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 café. The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes（细胞膜） 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 metabolized（新陈代谢） 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. The 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 can conclude from the passage ?

A, Sprayable Energy can be taken by mouth.

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

C. Sprayable Energy has not already gone into mass production

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

3.You will probably read this passage in the column of___________.

A. Food　　　 B. Health

C. Entertainment　　　 D. Energy.

4.What’s the best title of this passage?

A. Sprayable Energy----cheaper but more effective

B. Sprayable Energy----now or never

C. Sprayable Energy----a latest energy spray

D. Sprayable Energy----a new kind of coffee
