　　(2015·郴州高三调研)You might think I’d have little in common with a camel，but we do share one useful skill：Both of us can go for a very long time without water.Usually I start my day with a cup of tea，and then I might have a glass of water with my lunch and one with dinner，that’s about a liter of liquid in 24 hours.It feels like plenty，but apparently it’s not nearly enough.

　　After years of suffering headaches and poor digestion I spoke to a neurologist

　　about my regular headaches and a nutritionist about my poor digestion，and both told me I should be drinking up to three liters of liquid a day for my body to function at its best.I decided to conduct an experiment.What would happen if I drank the recommended amount every day for a month?

　　The photograph of me taken the day I started this trial demonstrates(展示) perfectly and rather frighteningly what a lack of hydration does to a face.I am 42，but have to admit I look more like 52 in this picture，which is shocking.There are dark shadows under and around my eyes，which make me look exhausted，a

　　profusion of wrinkles and strange reddish blotches，and my skin lacks any luster(光泽)．It looks dead.Even my lips look shriveled(枯萎的)．This is all classic evidence of poor hydration，apparently.

　　Every system and function in our body depends on water.It flushes toxins from the vital organs，carries nutrients to cells，provides a moist environment for ear，nose and throat tissues，and eliminates waste.

　　(2015·衡阳质检)How far would you be willing to go to satisfy your need to know？Far enough to find out your possibility of dying from a terrible disease？These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.

　　There are now more than a thousand genetic(基因的)tests，for everything from baldness to breast cancer，and the list is growing.Question is，do you really want to know what might eventually kill you？For instance，Nobel Prize－winning scientist James Watson，one of the first people to map their entire genetic makeup，is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年痴呆症)．

　　“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your life as you wait for that disease to hit you.It could really mess you up.”said Dr.Robert Green，a Harvard geneticist.

　　“Every ache and pain，”Smith suggested，“could be understood as the beginning of the end.”“That’s right.If you ever worried you were at risk for Alzheimer’s disease，then every time you can’t find your car in the parking lot，you think the disease has started.”

　　Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would，for lack of a better medical term，freak out.But Green and his team found that there was

　　“no significant difference” between how people handled good news and possibly the worst news of their lives.“In fact，most people think they can handle it.People who ask for the information usually can handle the information，good or bad，”said Green.

　　6．The first paragraph is meant to ________.

　　A．ask some questions

　　B．introduce the topic

　　C．satisfy readers’ curiosity

　　D．describe an academic fact

　　7．Which of the following is TRUE of James Watson?

　　A．He is strongly in favor of the present genetic tests.

　　B．He is more likely to suffer from Alzheimer’s disease.

　　C．He believes genetic mapping can help cure any disease.

　　D．He doesn’t want to know his chance of getting a disease.

　　8．According to Paragraphs 3 and 4，if a person is at a higher genetic risk，it is ________.

　　A．advisable not to let him know

　　B．impossible to hide his disease

　　C．better to inform him immediately

　　D．necessary to remove his anxiety

　　9．The underlined part “freak out” in Paragraph 5 is closest in meaning to “________”．

　　A．break down B．drop out

　　C．leave off

　　D．turn away

　　10．The study led by Dr.Green indicates that people ______.

　　A．prefer to hear good news

　　B．tend to find out the truth

　　C．can accept some bad news

　　D．have the right to be informed

　　(2015·湖南十三校高三联考)A busy life can be personally satisfying，but it may make you feel too tired to achieve the inner peace that will connect you with your true happiness.Begin with simplifying your life and working towards a more peaceful state of mind.

　　Recognize the differences between the things you need and the things you want.Our culture provides us with the message that materials will make our lives better.The reality is that most of these things will complicate our lives without bringing true happiness.Free yourself —learn to be satisfied with fewer materials and greater simplicity.

　　If you let someone else define your life.you’re missing the chance to follow your own desires.Your inner life is weakened when you are limited by conformity (遵从)．Why do you give up your freedom and allow all of your decisions to be defined by what others think you “should” do? Think for yourself.Let your passions be your guide.

　　Life is full of opportunities to earn money and give services.Learn new skills and make new friends.Some of us want them all and fill up our timetable with all kinds of activities.Rushing from one activity to another leaves you with no time to slow down.No matter how worthy you think your activities are，rethink them.Keep the ones that are most important and leave out the ones that are adding to the pace of your life with little return.

　　Life is forever changing，and you will never reach a point of simplicity and endless happiness.But each moment you spend on the path to simplicity does have the possibility to bring happiness to your life.

　　Title：Finding Happiness Through Simplicity

　　(2015·湖南部分重点中学联考)A study of the ant species Temnothorax longispinosus has revealed that it can spot its worst enemy and react with appropriate strategies.

　　The ant colonies are often invaded by slavemaker ants，which steal their brood.So when the ants spot a slavemaker，they attempt to kill it by biting and stinging.But the insects do not waste their energy on less threatening intruders(非法闯入者)．The results were published in the journal Nature.

　　The team，led by Inon Scharf and Susanne Foitzik from the Johannes Gutenberg University of Mainz in Germany，wanted to find out how these socially complex insects reacted to intruders of different species.

　　To do this，they brought ant colonies into their laboratory.In the wild Temnothorax longispinosus inhabits forests across the northeast of the US，where leaves of trees fall annually in autumn.They nest in cavities(洞穴)of rotten leaves or sticks in the leaf litter.

　　“We introduced workers of four different ant species into the ant colonies，”Dr.Scharf explained.The first was an unfamiliar species—one that didn’t share the ant’s habitat.The second was from the same species and the third was a familiar competitor—a related species that did inhabit the same areas.Finally，the ants encountered the most dangerous intruder—the slavemaker ant.

　　Slavemakers invade other ant colonies and steal their brood，often killing the host queen and workers in the process.The enslaved workers emerge from the stolen host brood inside the slavemaker nest.They then carry out routine tasks for the slavemaker—tending the queen，raising the young and hunting for food.

　　When the little Temnothorax longispinosus ants encountered a slavemaker，they attacked it—biting and stinging.When they met less threatening opponents，they simply tried to drag them from the nest.

　　“It is surprising—they’re making a clear distinction，”said Dr.Scharf.“But it makes sense in terms of evolution.They don’t waste their energy responding aggressively to every single intruder.It’s logical to adjust their response to the threat.”

　　1．What is the finding of the study according to the passage？(No more than 15 words)

　　________________________________________________________________________

　　2．What harm do slavemaker ants do when they invade other ant species？(No more than 15 words)

　　________________________________________________________________________

　　3．How did Temnothorax longispinosus ants probably deal with the first species in the experiment？(No more than 10 words)
