题目内容

3．The reason why he explained in the office was reasonable．把why换成that/which 或why去掉．

分析 他在办公室里解释的理由是合理的．

解答 答案是把why换成that/which 或why去掉．本题考查定语从句的引导词；题干中含有以reason为先行词的定语从句，将reason带入到定语从句，从句完整的表达为"he explained the reason in the office"，可见the reason在从句中做宾语；做宾语指代物可以用that或which，还可以省略，why 在从句中只能做状语，故答案是把why换成that/which 或why去掉．

点评 句子改错要在理解句子结构的基础上从词语搭配、词性、单复数、时态、非谓语动词等方面进行综合考虑，分析可能存在的错误；

I will share with you true story that happened a couple of day ago．One of my classmates bought a bag of snacks from a food store．A few classmates were then inviting to enjoy the snacks．Unluckily，all of us got poisoned and had stomachaches with their faces pale．They were quickly sent to a nearby hospital．Doctors examined them but gave them some medicine．They were out of danger soon before taking the medicine．This accident makes us to realize the seriousness of the food safe problem．Therefore，I strong suggest that the whole society pays more attention to it．
12．Thinking of buying a pair of new running shoes？Have the latest running shoe advertisements left you confused？To know which pair of shoes is the best for you，read on．
（36）B
If you do not know your foot size，I advise you to go to a footwear specialty shop and check your foot size．If the sizes of your feet vary，then your shoe size must match the size of your larger foot．
（37）EThis will help you identify your pronation（内翻）quickly．Wet your feet and stand on the bathmat．Observe your footprints．If your footprints indicate your entire foot，then you over-pronate．If your footprints show a very thin band between the ball of your foot and your heel，then you under-pronate．Normal pronation lies between over-pronation and under-pronation．
Time to buy．
When you buy your shoes also plays a major role in the fitting of your shoes．You should preferably shop for shoes in the late afternoon．（38）CThe feet have a tendency to expand while running．So buying shoes that match the largest size of your feet is always advised．
Curve（弯曲）of the shoes．
（39）GShoes with a curved shape will be the best for those who under-pronate．Shoes with a semi-curved shape will be suitable for those who have normal pronation．
Testing your shoes．
Once you have chosen your pair of shoes，you should test them．Walk and jump around in them．（40）FIf you don't feel comfortable，then ask for another pair．
Knowing how to choose running shoes is essential．It helps you avoid injuries．Get running shoes that fit you，instead of following those advertisements blindly．

A．Style of the shoes．
B．Know your feet．
C．Your feet are the largest then．
D．Choose the shoes in your favorite color．
E．You should also know your arch（足弓）shape．
F．Make sure that you arc comfortable in them．
G．If you have flat feet，then shoes with a straight shape are suitable for you．
13．Pre-school children who spend time together take on one another's personalities，new research had found．The study reveals that environment plays a key role I shaping people's personalities．
While genetics still forms the core of the human psyche（心灵），the research finds that personality traits are"contagious"among children．
"Our finding that personality traits are"contagious"among children flies a face of common assumptions that personality is ingrained（根生蒂固的） and can't be changed，"said Dr Jennifer Neal，associate professor of psychology at Michigan State University and co-author of the study．"This is important because some personality traits can help children succeed in life，while others can hold them back．"
The researchers studied the personalities and social networks of two pre-school classed for a full school year．One of the classes was a set of three-year-olds，and one a set of four-year-olds．Children whose friends were hard-working or outgoing gradually took on these personality traits over time．But children whose peers were anxious or easily frustrated did not take on these traits．
The new study is not the first to explore the contagious effects of personality traits．
A 2015psychology study found that rudeness at work can be contagious as it travels from person to person"like a disease"．Researchers form Sweden's Lund University claimed that even petty （微不足道的） behavior，like not inviting someone to a communal event or spreading rumors，can start the cycle off．The study found that seeing a supervisor being rude to an employee was enough to cause people to be rude to those around them．Often，those who experienced rudeness would be rude to others．
Dr Eva Torkelson，a psychologist at Lund University，said the most common cause of people acting rudely at work was imitating others．
"An important finding form our study is that those who behave rudely in the work[place experience stronger social support，which probably makes them less afraid of negative reactions to their behavior form managers and colleagues．"
Dr Torkelson believes companies need to be more aware of the harm that rudeness in the workplace can do，as it can grow and damage the atmosphere in the office．

32．What does the underlined word"contagious"mean in the second paragraph？B
A．Faulty．
B．Influential．
C．Harmful．
D．Troublesome
33．From the fourth paragraph，we can learn thatA．
A．children whose friends are hard-working can succeed more easily
B．children whose peers are easily frustrated can fail more easily
C．children of three years old have personalities that are more active
D．children of four years old have personalities that are less active
34．The 2015 psychology study indicates thatC．
A．rudeness at work should be banned totally
B．rudeness at work is beneficial occasionally
C．supervisors and employees can be influenced by the rudeness at work
D．rudeness at work like"a disease"cannot be changed
35．What can we conclude from Dr Eva Torkelson？B
A．People who behave rudely will not gain support at work．
B．Bad behavior can be imitated in the workplace，
C．Managers will be more friendly to their employees in the future．
D．Rudeness can be a motivation for most employees．
