20.Before birth,babies can tell the difference between loud sounds and voices.They can even distinguish their mother's voice from that of a female stranger.But when it comes to embryonic learning(胎教),birds could rule the roost.As recently reported in The Auk:Ornithological Adrances,some mother birds may teach their young to sing even before they hatch(孵化).New-born chicks can then imitate their mom's call within a few days of enering the world.
This educational method was first observed in 2012 by Sonia Kieindorfer,a biologist at Flinders University in South Australia,and her colleagues.Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs,When the eggs were hatched,the baby birds made the similar chirp to their mothers-a sound that served as their regular"feed me!"call.
To find out if the special quality was more widespread in birds,the researchers sought the red-backed fairy wren,another species of Australian songbird.First they collected sound data from 67 nests in four sites in Queenslang before and after hatching,Then they identified begging calls by analyzing the order and number of notes.A computer analysis blindly compared calls produced by mothers and chicks,ranking them by similarity.
It turns out that baby red-backed fairy wrens also emerge chirping like their moms.And the more frequently mothers had called to their eggs,the more similar were the babies'begging calls.In addition,the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom's voice were rewarded with the most food.
This observation hints that effective embryonic learning could signal neurological(神经系统的)strengths of children to parents.An evolutionary inference can then be drawn."As a parent,do you invest in quality children,or do you invest in children that are in need?"Kleindorfer asks."Our results suggest that they might be going for quality."

58.The underlined phrase in Paragraph 1 means"B".
A.be the worst                 B.be the best
C.be the as bad                 D.be just as good
59.What are Kleindorfer's findings based on?A
A.Similarities between the calls moms and chicks.
B.The observation of fairy wrens across Australia.
C.The data collected from Queensland's locals.
D.Controlled experiments on wrens and other birds.
60.Embryonic learning helps mother birds to identify the baby birds whichC.
A.can receive quality signals
B.are in need of training
C.fit the environment better
D.make the loudest call.

分析 本文是一篇科教类阅读,文章主要介绍鸟类在胎教方面可以称第一,有些鸟妈妈会教它们的孩子叫,甚至在它们孵化的过程中.有效地胚胎学习可以向鸟妈妈告知它们孩子的神经系统得到加强.

解答 58.B 词义辨析题.根据第二段As recently reported in The Auk:Ornithological Adrances,some mother birds may teach their young to sing even before they hatch(孵化).New-born chicks can then imitate their mom's call within a few days of enering the world.可知海雀近日报道:有些鸟妈妈会教它们的孩子叫,甚至在它们孵化的过程中.新出生的小鸡就可以模仿它们的妈妈叫声.由此可知,But when it comes to embryonic learning(胎教),birds could rule the roost.的意思是:说到胎教,鸟类可以称第一.即"rule the roost"的意思是:最好的.故选B.
59.A 理解判断题.根据第二段""可知,研究发现是对澳大利亚两种会鸟鸣的鸟儿进行了记录,根据第三段"the researchers sought the red-backed fairy wren,another species of Australian songbird."可知,研究人员并未在全澳洲范围展开调查;未对其它鸟类进行记录研究,排除BD项.根据倒数第三段"A computer analysis blindlycompared calls produced by mothers and chicks,ranking them by similarity."可知,故选A.
60.C 细节理解题.根据倒数第二段"the baby birds that mostclosely imitated their mom's voice were rewarded with the most food"和最后一段"Our results suggest that they might be going for quality."可知,模仿母鸟模仿得最好的雏鸟得到最多的食物,研究结果表明,母亲会选择质量好的雏鸟、孩子,即能比较好地适应环境的孩子.故选C.

点评 本文考察学生的理解推断能力以及细心程度,只要抓住文章的关键词,采用寻读的方法查找细节,就能找到正确答案.

11.A build-it-yourself solar still(蒸馏器) is one of the best ways to obtain drinking water in areas where the liquid is not readily available.Developed by two doctors in the U.S.Department of Agriculture,it's an excellent water collector.Unfortunately,you must carry the necessary equipment with you,since it's all but impossible to find natural substitutes.The only components required,though,are a 5'×5'sheet of clear or slightly milky plastic,six feet of plastic tube,and a container-perhaps just a drinking cup-to catch the water.These pieces can be folded into a neat little pack and fastened on your belt.
      To construct a working still,use a sharp stick or rock to dig a hole four feet across and three feet deep.Try to make the hole in a damp area to increase  the water catcher's  productivity.Place your cup in the deepest part of the hole.Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up-and out-the side of the hole.
      Next,cover the hole with the plastic sheet,securing the edges of the plastic with dirt and weighting the sheet's center down with a rock.The plastic should now form a cone(圆锥体) with 45-degree-angled sides.The low point of the sheet must be centered directly over,and no more than three inches above,the cup.
      The solar still works by creating a greenhouse under the plastic.Ground water evaporates (蒸发) and collects on the sheet until small drops of water form,run down the material,and fall off into the cup.When the container is full,you can suck the refreshment out through the tube,and won't have to break down the still every time you need a drink.

32.What do we know about the solar still equipment from the first paragraph?D
A.It's delicate.
B.It's expensive.
C.It's complex.
D.It's portable.
33.What does the underlined phrase"the water catcher"in paragraph 2 refer to?B
A.The tube.                 
B.The still.
C.The hole.                         
D.The cup.
34.What's the last step of constructing a working solar still?C
A.Dig a hole of a certain size.                     
B.Put the cup in place.
C.Weight the sheet's center down.                  
D.Cover the hole with the plastic sheet.
35.When a solar still works,drops of water come into the cup fromD.
A.the plastic tube                       
B.outside the hole
C.the open air                          
D.beneath the sheet.

8.Suppose you're in a rush,feeling tired,not paying attention to your screen,and you send an email that could get you in trouble.
Realisation will probably set in seconds after you've clicked"send".You freeze in horror and burn with shame.
What to do?Here are four common email accidents,and how to recover.
Clicking"send"too soon
Don't waste your time trying to find out if the receivers has read it yet.Write another email as swiftly as you can and send it with a brief title explaining that this is the correct version and the previous version should be ignored.
Writing the wrong name
The sooner you notice,the better.Respond quickly and briefly,apologising for your mistake.Keep the tone measured:don't handle it too lightly,as people can be offended,especially if your error suggests a misunderstanding of their culture(i.e.incorrect ordering of Chinese names).
Clicking"reply all"unintentionally
You accidentally reveal(透露)to the entire company what menu choices you would prefer at the staff Christmas dinner,or what holiday you'd like to take.In this instance,the best solution is to send a quick,light-hearted apology to explain your awkwardness.But it can quickly rise to something worse,when everyone starts hitting"reply all"to join in a long and unpleasant conversation.In this instance,step away from your keyboard to allow everyone to calm down.
Sending an offensive message to its subject
The most awkward email mistake is usually committed in anger.You write an unkind message about someone,intending to send it to a friend,but accidentally send it to the person you're discussing.In that case,ask to speak in person as soon as possible and say sorry.Explain your frustrations calmly and sensibly-see it as an opportunity to clear up any difficulties you may have with this person.

Cooking from Scratch W11 Change Your Life

Cooking from scratch is more than just making fresh food to eat. Your relationship to food will be transformed the more you handle ingredients(原料)and turn them into delicious recipes.

2. You begin to taste food differently.

All food, whether prepared from scratch or eaten in a restaurant # tastes different after you learn how to cook—because now you know what goes into creating a dish. 2.

3. You start to see your body in a different way.

The connection between what you put into your body and how it makes you feel becomes clearer, once you’re making the food yourself. 3.
