How I hate act dishonestly in exams! This morning, Henry tried to copy his answers. He whispered to me so that the teacher couldn't hear. I didn't know what to do it. If I didn't show him the answers, he might be mad. Henry is my friend. I really don't want to destroy our friendship. But showing him the answers would be something that went against my beliefs.

Do you find getting up in the morning so difficult that it's painful ? This might be called laziness, but　Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.

During the hours when you labour through your work you may say that you're "hot". That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak . For some　people the peak comes during the forenoon. For others it comes in the afternoon or evening No one has　discovered why this is so , but it leads to such familiar monologues（自言自語(yǔ)） as : "Get up, John! You'll be late for　work again !" The possible explanation to the trouble is that John is at his temperature-and -energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,　and which cycle each member of the family has.

You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help,　Dr. Kleitman believes . Maybe you're sleepy in the evening but feel you must stay up late anyway . Counteract（對(duì)抗/抵消）your cycle to some extent by habitually staying up later than you want to .If your energy is low in the morning　but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point.

Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch . Sit on the edge　of the bed a minute before putting your feet on the floor . Avoid the troublesome search for clean clothes by　laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring　more energy or concentration for your sharper hours.

1.If you wants to work more efficiently at your how point in the morning, you should _____.

A. change his energy cycle B. overcome his laziness

C. get up earlier than usual D. go to bed earlier

2.You are advised to rise with a yawn and stretch because it will _____.

A. help to keep your energy for the day's work

B. help you to control your temper early in the day

C. enable you to concentrate on your routine work

D. keep your energy cycle under control all day

3.What’s the best title of the passage?

A. Change Your Habits B. Save Your Energy

C. Daily Energy Cycle D. Temperature- and-Energy Peak

4.The text is probably taken from a _________.

A. news report B. research paper C. medical textbook D. fashion journal

科目：高中英語(yǔ) 來源：2015屆河南洛陽(yáng)第一高級(jí)中學(xué)高二下學(xué)期第一次月考英語(yǔ)卷（解析版） 題型：閱讀理解

On Oct4,2011 , I phone 4s made its international appearance at the press conference claimed by the Iphone cooperation . Ever since then , Iphone4s has become a hot cake and even made a fashion around the globe. Meanwhile , many new expressions come about in relationship with this type of high-tech products. “Jailbreak” is one of them.

“ Jailbreak” means to unlock the operating system of a mobile phone or other device so that it can run software which it is not normally authorized to use because of restrictions imposed（實(shí)施） by the device's manufacturer.

If someone jailbreaks a smartphone, tablet computer or other device（設(shè)備）, they use a special piece of software in order to remove the restrictions imposed by the manufacturer on the kind of applications that can be downloaded and run on the device. The concept of jailbreaking is most often associated with products from Apple Inc, such as the iPhone, iPod and iPad, which routinely restrict the user to applications licensed exclusively（獨(dú)家地） by Apple and purchased via its App Store. As well as wanting to lift the restriction（解除限制） on what kinds of applications they can purchase, those who jailbreak often do so as a reaction against what they consider as a form of censorship（監(jiān)控） imposed by Apple Inc in only allowing the use of their 'approved' apps.

The concept of jailbreaking dates back to July 2007, when it was applied to the iPhone within a month of the device's first release. This first occurrence related to the adding of custom ringtones（個(gè)性鈴音）, but the idea quickly developed as a means to lift the restriction and equip the phone with games and other applications not licensed by Apple Inc.

1.“jailbreak” means that________________.

A. Criminals escape out of the jail

B. People make a great breakthrough in their life

C. It is a way to lift the restriction specially imposed by the Iphone manufacturer.

D. It’s a breakthrough beyond one’s dream.

2.Which is probably the correct Chinese meaning of a hot cake？

A.熱蛋糕 B. 搶手貨 C. 熱門話題 D. 最高禮遇

3.Which one is the correct statement from this passage?

A. The original mobile phones also require jailbreaking

B. People jailbreak not only in order to lift the restrictions of applications licensed by the Iphone Cooperation.

C. The concept of jailbreak is seldom associated with products from Apple Inc

D. The concept of jailbreak dates back to the twentieth century
