Ⅰ.阅读理解

(2019·云南曲靖一中质检)
It’s known to all that coffee can make you feel more awake，and now it seems that coffee may also improve your maths skills.And the best news is that you don’t even need to drink it to see the improvements—you just need to smell it.Coffee is actually very healthy.It is loaded with antioxidants and beneficial nutrients that can improve your health.The studies show that coffee drinkers have a much lower risk of developing several serious diseases.
A new study by researchers from Stevens Institute of Technology has revealed that the scent of coffee may help your maths skills.Professor Adriana Madzharov，who led the study，said，“It’s not just that the coffee-like scent helped people perform better on analytical tasks，which was already interesting.But they also thought they would do better，and we proved that this expectation was at least partly responsible for their improved performance.”
In the study,100 business students took a 10-question algebra test.Half the group took the test in the presence of a coffee-like scent，while the other half took the test in an unscented room.The results revealed that the group in the coffee-smelling room scored significantly higher on the test than those in the unscented room.
In a follow-up study，the researchers quizzed 200 new participants on their belief about various scents and their effects on human performance.Their answers showed that they believed they would feel more alert in the presence of a coffee scent.This suggests that their expectations about performance may have influenced their improved skills.
The researchers believe that the findings could have major effects on the real world.Professor Madzharov added，“Olfaction(嗅觉) is one of our most powerful senses.Employers，architects，building developers，retail space managers and others，can use subtle scents to help shape employees’ or occupants’ experience with their environment.It’s an area of great interest and potential.”

语篇解读　如今，由于使用现金的高成本和迅速增加的替代物的出现，现金交易可能变得不那么流行了。实际上，现金在支付手段中是独一无二的，因为任何人在任何时间、任何地点都能进行交易，而且没有第三方介入。因此，现金支付不可能完全消失。
25．答案　growing
解析　考查非谓语动词。设空前有定冠词the，其后为名词number，因此，设空处应作定语；number与grow之间为逻辑上的主动关系，因此，应用现在分词作定语。故填growing。
26．答案　involved
解析　考查非谓语动词。此处为“with＋宾语＋宾补”结构，involve和third parties构成逻辑上的被动关系，因此，应用过去分词作宾补。故填involved。
27．答案　comes
解析　考查动词的时态。设空句描述一般事实，应用一般现在时，且此句为倒装句，主语为strong privacy protection，故动词用第三人称单数形式。故填comes。
28．答案　a
解析　考查冠词。句意为：当人们随身带着现金时，他们会有一种安全感。a sense of...为固定搭配，意为“……感”。故填a。
29．答案　digitally
解析　考查词性转换。设空处修饰形容词native，应用副词。故填digitally。
30．答案　to turn
解析　考查非谓语动词。take some time to do sth.为固定搭配，意为“做某事需花费……时间”，故填to turn。
31．答案　merchants
解析　考查名词单复数。merchant商人，为可数名词，其前有Some修饰，应用复数形式。故填merchants。
32．答案　is considered
解析　考查动词的时态和语态。此处介绍一般情况，应用一般现在时，且consider和句子主语Cash之间为被动关系，因此应用被动语态。故填is considered。
33．答案　who
解析　考查定语从句。分析句子结构可知，设空处引导定语从句，先行词是someone，指人，且在从句中作主语，故用who引导该从句。
34．答案　to
解析　考查介词。根据句意可知，设空处表示“向，朝，往(某个方向或某处)”，故填介词to。
