【題目】

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 or1 to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be2 reasons.

According to a new study, an3 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 4 . It makes us stay5 in a new environment.

For the study, 35 young volunteers6 to sleep in a sleep lab for several days.

Meanwhile, researchers watched their brain activities.

According to the researchers, on their7 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 got an increasingly8 sleep experience.

The findings suggest that the different rhythms of the sides of the brain affect our sleep. When the two sides work9 , the balance between them is broken. So, the brain can't relax and is sensitive to10 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.

【解析】

本文是一篇說明文.文章講述的是我們?yōu)槭裁茨苋胨?/span>。

1句意:發(fā)現(xiàn)入睡很難或者不可能。

根據(jù)句意我們躺在別的床上很難入睡,空處的詞應該跟difficult表達的感情色彩一致,impossible表不可能,適合句意,由possible變換而來。故填impossible。

2句意:但是或許可能有別的理由。

下文列舉了除床不舒適以外的其他失眠原因,所以漢語應為"其他的"。有代詞others變?yōu)樾稳菰~other。故填other

3句意:根據(jù)新研究,一個重要的原因是科學家口中的 "守夜效應"

根據(jù)句意及an的提示可知,空處應填形容詞重要的。有名詞importance變?yōu)閷男稳菰~important。故填important 。

4句意:他們認為大腦一側像時鐘一樣警示我們潛在的危險。

空處是warn 的直接賓語,應該用名詞充當,句意為大腦一側像時鐘一樣警示我們潛在的危險, 有形容詞 dangerous變?yōu)閷拿~danger。故填danger.

5句意:它使我們在新的環(huán)境中保持失眠。

動詞stay作為系動詞后面常跟形容詞作表語,整篇文章在談失眠,stay awake 表失眠。有動詞wake變?yōu)閷男稳菰~awake。故填awake

6句意:為了這個研究,讓35個志愿者在睡眠實驗室中睡了幾天。

根據(jù)句意 "35個志愿者在睡眠實驗室中睡了幾天" ,句子主語是志愿者,與動詞是被動關系,要用被動語態(tài),時態(tài)是一般過去時,故填were allowed.

7句意:研究者發(fā)現(xiàn),第一夜左腦比右腦活躍,人們很難入睡。

根據(jù)句意 "研究者發(fā)現(xiàn),第一夜左腦比右腦活躍,人們很難入睡" 可知空處應該填第一 "first" 。有基數(shù)詞one變?yōu)閷男驍?shù)詞first。故填first。

8句意:隨著時間推移,參與者獲得了越來越好的睡眠。

上文談到隨著時間推移,左腦活動減少,甚至十分穩(wěn)定,說明參與者獲得了越來越好的睡眠,increasingly后面應加good表越來越好。故填good。

9句意:當大腦兩側不同時工作時,他們之間的平衡被打破。

根據(jù)句意:當大腦兩側不同時工作時,他們之間的平衡被打破可知,空處要填不同的副詞來修飾動詞work。有名詞difference變?yōu)閷母痹~differently。故填differently。

10句意:大腦無法放松,對周圍的任何奇怪的事物都很敏感。

根據(jù)句意大腦無法放松,對周圍的任何奇怪的事物都很敏感,可以推出空處應填anything表任何事。有something變化而來。故填anything。

語法填空題是考查學生的語言運用能力。解題時,要在理解文章的基礎上,靈活運用語法知識,如詞性,時態(tài),名詞單復數(shù),連接詞,代詞,冠詞等判斷空白處應填寫的內容。答完后,還要通讀全文,核對所填單詞形式是否正確,是否符合語境。

【題目】 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!

1The writer finds studying in the USA is________.

A.funB.easyC.boringD.challenging

2According to paragraph 2, Mr. Peters probably agrees that ________.

A.learning baseball rules is difficultB.baseball is American’ favorite sport
