(2016·河南洛阳统一考试)
Have you dreamed of building your own machine？Do you wish you could invent something new？Here we look at a few British inventions of recent times.
Adaptive glasses
Do you wear glasses？If so，can you imagine life without them？In 1985，Joshua Silver，a professor at Oxford University，asked himself，“Can I invent a pair of glasses that could be changed by the wearer？” He designed two plastic lenses (透镜) that are filled with a special liquid.Using syringes (注射器) you change the liquid between the lenses until you can see clearly.The glasses are not beautiful but they are easy to use and cheap to make.
The wind-up radio
When you switch your TV on tonight，think about all those people without electricity.Thinking about this，Trevor Baylis came up with the idea of designing a radio that could be powered by hand.In common with Joshua Silver he wanted his invention to be cheap and easy to use.He wanted even the poorest people in
developing
countries，who don’t have electricity and cannot afford batteries，to use it.The radio has a generator (发电机) which is powered by turning a handle.In 1996 it won the BBC Design Award for Best Product and Best Design.
The Dyson vacuum ( 真空) cleaner
In many homes around the world you can see a cleaner that looks like a spaceship.This is the Dyson vacuum cleaner which uses something called ”cyclonic separation“ to separate the dirt.You do not need a bag for your cleaner and it does not get blocked so it is very practical.The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner.He decided he could design a better one and in 1993 he opened his own factory.The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.
The Zapata Flyboard
Have you ever dreamed of zooming through the water and leaping in the air like a dolphin？Now you can thanks to a flyboard，built by water sports enthusiast Frank Zapata.With it you can dive back in the water and out again.It’s possible to jump to incredible heights out of the water—over 30 feet.The basic flyboard model comes in at ￡4,200.
So keep dreaming and inventing.One day you might get it right.
1．Which might be the best title for the passage?
A．Greatest Inventions B．Scientists’ Stories
C．Magic Glasses
D．Beautiful Minds

(2016·山西省六所重点中学联考)
What happens inside the skull of a soccer player who repeatedly heads a soccer ball？That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players，and some anxiety among those of us with soccer-playing children.
For the study，researchers at the Albert Einstein College of Medicine in New York selected 34 adults，men and women.All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues.Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year，as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned，using a complicated new MRI technique which can find structural changes in the brain that can’t be seen during most scans.
According to the data they presented at a Radiological Society of North America meeting last month，the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory，attention and the processing of visual information，compared with players who had headed the ball fewer times.
This pattern of white matter loss is “similar to those seen in traumatic (外伤的) brain injury”，like that after a serious concussion，the researchers reported，even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them，forgetting or fumbling the words far more often than players who had headed the ball less.
5．The passage is most probably a________.
A．news report B．research report
C．story for soccer players D．text for doctors
6．From the passage we can conclude that frequent heading may have________.
A．significant effect on one’s brain
B．little effect on one’s brain
C．nothing to do with the brain injury
D．one’s memory improved
7．What is likely to be the cause of memory loss?
A．Playing soccer frequently.
B．Tests of their memory.
C．White matter loss.
D．Information processing.
8．The underlined word “fumbling” is closest in meaning to________.
A．remembering B．misunderstanding
C．recalling D．missing

课时作业(九)
Ⅰ.单项填空
1．解析： 根据答语后一句中的内容可知说话人“一点也不介意对方把空调关掉”。
答案： C
2．解析： 句意为：医生认为好好休息是有好处的。根据句意不定式短语to have a good rest在宾语从句中作真正的主语，只有it可作形式主语，故选D项。
答案： D
3．解析： 考查情态动词。句意为：在压力之下，即使是一个很温柔的人都可能会生气、发脾气。情态动词can在此处表示“可能会”。
答案： C
4．解析： 考查时态。句意为：我弟弟学了几个月计算机，然后才发现自己酷爱烹饪，于是去了一所烹饪学校。根据句意及before可知，study这一动作先于discovered和went发生，故用过去完成时态，选C。
答案： C
5．解析： 句意为：中国政府建议多关注保护环境。advise＋that...(should)＋do sth.，should可省略，故排除A、B选项，pay attention to中to为介词，故D项正确。
答案： D
6．解析： 考查名词。appreciation感激，欣赏；inspiration激励；satisfaction满足，满意；ambition抱负，野心。句意为：因为没有更好的表达爱和感恩的方式，这就很容易明白为什么在母亲节大家都去花店。

7．解析： so that引导目的状语从句，多与情态动词连用。in case“倘若；万一”，表假设；in order that可引导目的状语从句，但in order不可；now that “既然”，引导条件状语从句。根据题意应选A项。
答案： A
8．解析： 句意为：——我们想要个双人间。——对不起，除了两个可以看到海景的单人间外，所有的房间都已被预订了。依据上文的sorry可知，这里强调对现在的影响，要用现在完成时态，再者reserve与主语之间是动宾关系，要用被动语态，排除C、D两项；but是介词，对谓语动词的单复数不造成影响，这里谓语动词的单复数形式应与all保持一致，故选A。
答案： A
9．解析： 句意为：在会议上，通过热烈的讨论之后新的计划形成了。这将对人们的文化生活产生巨大的影响。come into being形成，产生；have a great effect on对……有巨大的影响。

答案： D
12．解析： 考查冠词用法。本题中所考查的两个短语均为固定短语，at a loss茫然，不知所措；out of question没问题，行，此短语也可为“毫无疑问”之意。
