15．If last year was all about virtual reality （VR 虚拟现实），then 2017belongs to augmented reality （AR，增强现实）．It's been around since the early 1990s，but recent developments have seen AR put into the hands of almost anyone with a smartphone．
Using special software，AR allows users to see virtual objects in the real world．Hit apps like game Pokemon Go and messaging app Snapchat mean that it's more widely used than VR．But it seems that companies have bigger plans up their sleeves．
This month，Taiwan tech giant Asus released its latest smartphone，the Zenfone AR．What makes it stand out is the cutting-edge （前沿的） AR tech it uses-Google Tango．"Tango-equipped phones can understand the physical space by measuring the distance between the phone and objects in the real world．"tech site Android Authority explained．
Tango is thought to be the next leap forward in tech，and dozens of companies have already created innovative （创新） new apps for it．Measuring walls or curtains in your home，viewing the solar system in your bedroom，or checking what a new table would look like in your living room are all possible using the special cameras and sensors （传感器） of Tango smartphones．
But it's not all just about fun and games．Present location technology in smartphones isn't 100 percent accurate，meaning navigating （导航） indoors is difficult，but Tango devices'special sensors allow them to"see"any in-door space．It's hoped that blind people will be able to use this technology to help them find their way around inside buildings．
There are still problems with this，though，John Brownlee of Co．Design says，"Let's say you need to direct a blind person to walk 50 feet in a straight line：How do you communicate to him or her what a foot is？"he wrote．
Google is working to solve these issues，however．"Nearly 20 percent of the US population will have a disability during their lifetime，"Eve Anderson，head of Accessibility Engineering at Google，wrote on the company's website．"That's why it's so important to build tools to make technology easy for everyone．"

32．According to the passage，ARB．
A．is a newly-developed technology．
B．connects the virtual objects to the real world．
C．is limited to games and social network apps．
D．has taken the place of VR in most smartphone apps．
33．What can you do with a Tango-equipped smart phone？C
a．Measuring curtains in your home．
b．Helping blind people find their way indoors．
c．Viewing universe at home．
d．Designing a new table for your living room
A．a&bB．b&cC．a&cD．c&d
34．What can we learn about Google of this passage？D
A．Google produces the cutting-edge smartphone，the Zenfone AR．
B．Google has found a solution to guiding blind people indoors．
C．Present location technology limits Tango devices'accuracy of indoor navigation．
D．Google focuses on improving everyone's life quality when developing products．
35．What is this passage mainly about？A
A．The latest development in the field of AR．
B．Smartphones that bring AR to our life．
C．The launch of a new smartphone，Zenfone AR．
D．How the blind have benefited by Google Tango．

1．One of the strangest features of motherhood is that the vast majority of mothers prefer to cradle their babies in the left arm．Why should this be？The obvious explanation is that the majority of mothers are right handed and they wish to keep their right handed and they wish to keep their right hand free．Unfortunately，this explanation cannot apply，because left-handed mothers also favor their left arm for holding their babies．The precise figures arc 83 percent for right-handed mothers and 73 percent for left-handed mothers．
The most likely explanation is that the mother's heart is on the left side and，by holding the baby in her left arm，she is unconsciously bringing her baby closer to the sound of the heart beat．This is the sound the baby heard when it was inside the mother's womb and which is therefore an association with peace，comfort and security．
Tests were carried out in nurseries where some babies were played the recorded sound of a human heart beat，and，sure enough，went to sleep twice as quickly as the others．We also know that the sound of mother's heart is quite audible inside the womb and that the unborn baby has a well-developed hearing．
It is interesting that fathers show less of this left-side bias （偏爱） than mothers，suggesting that the human female is better programmed than her partner for carrying a baby．Alternatively，she may unconsciously adjust her holding behavior to make baby fell more secure．Some new observations on our closest animals'relatives，the chimpanzees and gorillas，have revealed that they too show a strong bias for holding their babies on the left side．The precise figures were 84 percent for chimpanzees and 82percent for gorillas，remarkably close to the human percentages．
Recently a possible additional value in cradling babies on the left side has been suggested．It has been pointed out that，because，the two sides of the brain are concerned with different aspects of behavior，it is possible that the mother，in cradling the baby to her left，is showing the baby her"best side"．It is claimed that the emotions are expressed more strongly on the left side of the human face and that she therefore gives the baby a better chance to read her emotional mood changes as it gazes up at her．Furthermore，the mother's left eye and ear are more tuned into emotional changes in her baby than her right eye and ear would be．So in addition to the baby's seeing the more expressive parts of its mother，there is further advantage that the mother is herself more sensitive to the left-held baby．This may sound far-fetched，but just possibly，it could provide a slight extra benefit for those mothers displaying the strange one-sided bias when cradling their infants．
How does a bias occur？Do the mothers have an instinctive preference for it，or do they learn it by trial and error，unconsciously adjusting the position of the babies until the babies are calmer？The surprising answer is that it seems to be the baby not the mother who controls the bias．Observation of new born infants when they were only a few hours old revealed that they come into the world with a pre-programmed tendency to turn their head to the right．If the new born baby is gently held in a dead central position and then released，it naturally swings to the right far more often than to the left．This happens in nearly 70percent of babies．This may be only a part of explanation，because the holding bias is 80percent not 70percent，but it adds a further intriguing chapter to the story．
