【题目】
ask dangerous difference good importance one
allow others possible sleep something wake
Many of us have had this experience: we lie down in a bed but not our own ones, perhaps at a friend's house or in a hotel room, and find it difficult or【1】 to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be【2】 reasons.
According to a new study, an【3】 reason is what the scientists call "first night effect" . They believe that one side of the brain acts as a "night watch" to warn us about potential( 潜 在 的 )【4】 . It makes us stay【5】 in a new environment.
For the study, 35 young volunteers【6】 to sleep in a sleep lab for several days.
Meanwhile, researchers watched their brain activities.
According to the researchers, on their【7】 night, the left brains were more active than the right brains and people had a hard time sleeping. However, left-brain activity decreased as days went by, falling even to the point of complete calm. In this process, the participants( 参 与 者 )got an increasingly【8】 sleep experience.
The findings suggest that the different rhythms of the sides of the brain affect our sleep. When the two sides work【9】 , the balance between them is broken. So, the brain can't relax and is sensitive( 敏 感 的 )to【10】 strange in the surroundings.
If you have ever had what you think is "first night effect" , researchers suggest that you bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.
【答案】
【1】impossible
【2】other
【3】important
【4】danger
【5】awake
【6】were allowed
【7】first
【8】good
【9】differently
【10】anything
【解析】
本文是一篇说明文.文章讲述的是“我们为什么能入睡”。
【1】句意:发现入睡很难或者不可能。
根据句意我们躺在别的床上很难入睡,空处的词应该跟difficult表达的感情色彩一致,impossible表不可能,适合句意,由possible变换而来。故填impossible。
【2】句意:但是或许可能有别的理由。
下文列举了除床不舒适以外的其他失眠原因,所以汉语应为"其他的"。有代词others变为形容词other。故填other。
【3】句意:根据新研究,一个重要的原因是科学家口中的 "守夜效应" 。
根据句意及an的提示可知,空处应填形容词“重要的”。有名词importance变为对应的形容词important。故填important 。
【4】句意:他们认为大脑一侧像时钟一样警示我们潜在的危险。
空处是warn 的直接宾语,应该用名词充当,句意为大脑一侧像时钟一样警示我们潜在的危险, 有形容词 dangerous变为对应的名词danger。故填danger.
【5】句意:它使我们在新的环境中保持失眠。
动词stay作为系动词后面常跟形容词作表语,整篇文章在谈失眠,stay awake 表失眠。有动词wake变为对应的形容词awake。故填awake。
【6】句意:为了这个研究,让35个志愿者在睡眠实验室中睡了几天。
根据句意 "让35个志愿者在睡眠实验室中睡了几天" ,句子主语是志愿者,与动词是被动关系,要用被动语态,时态是一般过去时,故填were allowed.
【7】句意:研究者发现,第一夜左脑比右脑活跃,人们很难入睡。
根据句意 "研究者发现,第一夜左脑比右脑活跃,人们很难入睡" 可知空处应该填第一 "first" 。有基数词one变为对应的序数词first。故填first。
【8】句意:随着时间推移,参与者获得了越来越好的睡眠。
上文谈到随着时间推移,左脑活动减少,甚至十分稳定,说明参与者获得了越来越好的睡眠,increasingly后面应加good表越来越好。故填good。
【9】句意:当大脑两侧不同时工作时,他们之间的平衡被打破。
根据句意:当大脑两侧不同时工作时,他们之间的平衡被打破可知,空处要填“不同的”副词来修饰动词work。有名词difference变为对应的副词differently。故填differently。
【10】句意:大脑无法放松,对周围的任何奇怪的事物都很敏感。
根据句意大脑无法放松,对周围的任何奇怪的事物都很敏感,可以推出空处应填anything表任何事。有something变化而来。故填anything。
语法填空题是考查学生的语言运用能力。解题时,要在理解文章的基础上,灵活运用语法知识,如词性,时态,名词单复数,连接词,代词,冠词等判断空白处应填写的内容。答完后,还要通读全文,核对所填单词形式是否正确,是否符合语境。

【题目】 I am studying English in a language school in the USA. It is the second week and everything is new to me. Because of the different language and the new environment, I find it difficult to adapt to school life here.
In yesterday’s class, Mr. Peters talked about baseball. He said, “baseball is one of the most popular sports in the USA. If you hope to speak English well, you must understand baseball. First, you need to know the rules. Then you need to try to find how it has to do with daily life.”
He gave us some expressions and let us guess the meanings. Unluckily, I had never watched a baseball game before, so I sat quietly and just listened to the others. After school, I took out a dictionary and asked Jake, one of my friends in the neighboring class, for help. Jake was kind and patient and he has been in the USA for several years. He tried to teach me the baseball rules. I learned that baseball is a game between two teams of nine players. In baseball, a player on one team throws a small round ball at the player on the other team, who tries to hit it back with a bat.
He told me more rules of the game, but the more he said, the more confused(困惑的) I felt! Maybe one day I need to watch a real game to understand it better!
【1】The writer finds studying in the USA is________.
A.funB.easyC.boringD.challenging
【2】According to paragraph 2, Mr. Peters probably agrees that ________.
A.learning baseball rules is difficultB.baseball is American’ favorite sport
C.every student should learn to pay baseballD.understanding baseball is helpful in learning English
【3】Why did the writer keep quiet in yesterday’s class?
A.He knew nothing about baseball.B.He could not follow the teacher.
C.He was too shy to speak.D.He did not like the teacher.
【4】The writer wrote the passage to ________.
A.say sorryB.ask for advice
C.compare two different culturesD.describe his personal experience
