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 that 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 （自言自语）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 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 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 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 for your sharper hours .If you want to work better at your low point in the morning, you should .
| A．change your energy cycle | B．overcome your laziness |
| C．get up early than usual | D．go to bed earlier |
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 get your energy on your routine work |
| D．keep your energy cycle under control all day |
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 |
The text is probably taken from a ______.
| A．news report | B．research paper |

Security—for the information on your smartphone, as well as for the phone itself is a hot topic these days．The truth is that you’re packing a lot of sensitive information on your phone, and you should keep it safe．
When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map．You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data．
Android does not have an exact equivalent(等价物), but there are plenty of alternatives．A free app called Lookout offers the find my phone feature．The paid version allows you to wipe the data from your phone remotely．
Then there is your coffee shop’s WiFi network．Anyone with minimal technical expert skill can snoop on(窥视) people using shared wireless networks, harvesting passwords and other personal data．Lookout’s apps will caution you when you’ve logged on to an insecure network, but cannot protect you once you’re there．
In order to protect yourself on such networks, you can use a virtual private network, or V．P．N．This turns all your activity into nonsense to anyone trying to read along with you from across the Starbucks．It also keeps websites from tracking you and, if you’re traveling, allows you to get access to sites that may be blocked in other countries．
If you have an iPhone, the simplest V．P．N．app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing (浏览), as opposed to other V．P．N．apps that require you to start them up manually(手动)．This matters, because even if you decide you want a V．P．N．app, you want to spend approximately zero time thinking about it．For the most part, that was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning．I found myself having to turn the app on and off sometimes, which involved setting my phone constantly．
If even reading about the setting on your phone drives you crazy, then it is probably best to stay away from a V．P．N．app．But if you’re the type who can’t resist checking your bank balance from your comer bar, the hassle (麻烦) may be preferable to the risk．Which of the following can warn you against the insecure network?
| A．Android |
| B．V．P．N． |
| C．Lookout |
| D．Find My iPhone |
By using V．P．N．, users can ________．
| A．find their lost phone on the Internet |
| B．remove all the data form the phone remotely |
| C．check the bank balance now and then |
| D．save their browsing from being tracked |
The underlined word “that” in Para．6 refers to the fact that _________．
| A．a V．P．N．app kicks in automatically |
| B．the users starts V．P．N．apps manually |
| C．the app take a while to connect |
| D．users spend no time thinking about it |
One evening last summer, when I asked my 14 year old son, Ray, for help with dinner, his response shocked me．"What’s a colander(漏勺)? " he asked．
I could only blame myself．In the family, nobody else’s hands went in the sauce except my own．But that night, as I explained with a touch of panic that a colander is the thing with holes in it, I wondered what else I hadn’t prepared Ray for．
As parents, while we focus on our sons’ confidence and character, we perhaps don’t always consider that we are also raising someone’s future roommates, boyfriends, husbands, or fathers．I wanted to know that I’d raised a boy who would never ask the woman in his life, "What’s for dinner?" So I came up with a plan: I would offer Ray a private home economics course．I was delighted to find that he didn’t say no．For two hours, three days a week, Ray was all mine．One day, as his tomato sauce reduced on the stove, he washed and seasoned a chicken for roasting．Then he rolled out the piecrust (馅饼皮) and filled it with apples, all while listening to my explanation on the importance of preheating an oven．
I knew that he would rather have been shooting hoops in the driveway than learning to mend socks with his mother—he tried to beg off sewing lessons, even though I insisted that one day, someone would find the sight of him fixing his own shirt very attractive— but it couldn’t be denied that he was learning, and more than just housekeeping．"I appreciate what you do as a mom," he told me one day．Ray now understands the finer points of cooking, and more importantly, he realizes there’s nothing masculine (男子气概的) about being helpless．
Now, not only can he make his own dinner, but also he can make a big meal for his family．That’s what I call a man．I’m glad that I prepared so great a present for my future daughter in law．Why was the author shocked at her son’s response?
| A．Because he was not well behaved． |
| B．Because he refused to help with dinner． |
| C．Because he didn’t know the common kitchen tools． |
| D．Because he was very curious about kitchen tools． |
In the author’s opinion, some parents pay little attention to _______．
| A．building up children’s confidence |
| B．telling kids what is right and wrong |
| C．preparing children for their future life |
| D．making children live a hard life |
After learning to do housework, Ray _______．
| A．fell in love with sewing |
| B．did other work in the house |
| C．began to be more hardworking |
| D．acknowledged his mother’s efforts |
We can infer from the text that Ray _______．
| A．made great progress in cooking． |
| B．always thought housework interesting． |
| C．preferred sewing to cooking． |
| D．was unwilling to learn cooking at first． |
What would be the best title for the text?
| A．Useful education for boys |
| B．The importance of housework |
| C．Boys should be involved in housework． |
| D．Cooking and sewing make boys masculine． |

“Beauty is only skin deep." This expression means that beauty is only a temporary surface quality. Some beauty products can cause lasting damage that goes far below the surface of the skin.
In America，many people use sunlight and non-natural light to darken their skin. Health experts advise against what is called“tanning”because of its links to akin cancer. In the African country of Senegal（塞内加尔），some women take health risks trying to do just the opposite.
An average beauty supply shop in Dakar has many kinds of skin-lightening creams and soaps. The World Health Organization says that 25％of Senegalese women use skin-lightening production a usual basis. These products can contain chemicals，like mercury（汞），hydroquinone（对苯二酚），etc. These are dangerous ingredients that can cause cancer and possibly other physical damage to the akin. They can actually burn the eyes and skin.
Shop worker Adama Diagne advises her visitors to avoid the stronger products that promise fast results. She users a cream that is made from carrots，not the strong chemical，hydroquinone. She says that it is a personal choice and that no one pressures her. Some women want to be black every day，but for her，she likes to be a shade of brown.
Women in Senegal say they lighten their skin for the same reason that women all over the world make changes to their appearance. They say they want to look beautiful，to find a husband， to stand out in a crowd or simply to look great for a special event.
This thinking troubles Senegalese film-maker Khardiata Pouye Sall. So，she made“This Color That Bothers Me"，a film about the subject of skin lightening. She said，“I used the most shocking images so that women would see the dangers. It is hard to understand why a woman says that dark skin is not beautiful. It is in their heads. They want to please a man，to he loved or they want to please society，to succeed."
Ms. Sall says that the government needs to better control the marketing and the sale of skin-lightening products. But she adds that education is the best way to persuade people against using them.The underlined part“the opposite" in Paragraph 2 means some Senegalese women ．
| A．use sunlight to darken their skin |
| B．try creams to prevent skin cancer |
| C．use products to lighten their skin |
| D．take health risks to become beautiful |
According to Adama Diagne，women shouldn't believe ·
| A．beauty is just a personal choice |
| B．a cream from carrots is healthier |
| C．it is beautiful to be black every day |
| D．a product can make you beautiful quickly |
We can infer that women in Senegal ．
| A．attract attention with shockingimages |
| B．don't consider dark skin to be beautiful |
| C．find it hard to understand the true beauty |
| D．put beauty in the first place in their heads |
What is Sall's attitude towards skin-lightening products?
| A．Unsupportive. | B．Casual. |
| C．Responsible. | D．Positive. |
