For the sixth graders，every hour of sleep above the

10、一項新的研究發(fā)現(xiàn)，睡眠過少的小學生更容易發(fā)胖。 1．C　解析：句意理解題。畫線句表示的字面意思是“先有雞還是先有蛋”，結(jié)合上下文的內(nèi)容可知，文章引用這句話是為了表明“是睡眠少導致了肥胖還是肥胖導致了睡眠變少”這個問題還沒有定論。下文的“In other words, it hasn't been clear whether kids who weigh too much have trouble sleeping, or whether sleeping less leads to weight gain. Both scenarios(可能出現(xiàn)的情況) seemed equally pos

11、sible”是解題的關鍵提示信息。 2．D　解析：細節(jié)理解題。根據(jù)第四段中的“The scientists found no relationship between weight and the students' race or gender”可知選D項。 3．A　解析：寫作手法題。文章主要介紹了一項研究，并列舉了很多同該研究相關的數(shù)據(jù)，故選A項。 4．B　解析：標題判斷題。根據(jù)文章內(nèi)容尤其是第一段中的“A new study has found that elementary school students who slept too little were more likely

12、 to gain pounds”可知，本文主要介紹了一項新的研究發(fā)現(xiàn)，睡眠少會增加肥胖的概率。故B項作文章標題最佳。 Ⅱ.閱讀填空 [2017·安徽合肥二檢] Everybody knows the importance of drinking enough water.As we all know，drinking water benefits your skin，muscles and organs.__1__ The main reason for that is related to human biological needs.When you're a baby，you'r

18、e a day or never，lost just 1.76 pounds. G．So kids should drink more water instead of coke to keep healthy. 答案：[解題導語]我們都知道喝水的重要性，但是你知道喝水也能減肥嗎？ 1．E　解析：第一段闡明喝水的重要性；下一段第一句則說喝水是人類的生理需要。由此可知，設空處仍然是講喝水的好處。E項意為“喝水還能有助于防止某些疾病并能改善心情?！狈险Z境。 2．A　解析：上文提出喝水對皮膚、肌肉和器官有好處，還有助于預防疾病和改善心情；下文中則提出了喝水有助于減肥，這是另一個好處。故選A

19、項。 3．B　解析：上文提出研究者的發(fā)現(xiàn)，然后是一些具體的研究過程，此處起著承上啟下的作用，B項中的the study與上文的study與The researchers對應，而其中的控制體重與下文中的實驗過程相關。故選B項。 4．F　解析：本段主要介紹喝水減肥的實驗過程及結(jié)果?？崭袂爸v到一天三餐都喝水的人減掉了9.48磅，實驗應該有對比，因此，F(xiàn)項中對比數(shù)據(jù)符合語境。 5．C　解析：本段是總結(jié)性段落：僅僅喝水就可以減肥，這是非常簡單的。C項是一句總結(jié)性語言，而且與下文內(nèi)容相符。故選C項。 Ⅲ.語法填空 [2017·湖北八校二聯(lián)] In recent years many TV sh

23、ms as well as functions.Meanwhile，the 10.________(medium) should also safeguard the values of our society. 答案：[解題導語]娛樂節(jié)目不僅要娛樂觀眾，同時應該承擔起更多的社會責任。 1．have received　解析：考查動詞的時態(tài)。句意：這些節(jié)目，從才藝到相親真人秀都已經(jīng)獲得了商業(yè)上的成功和公眾的關注。本句是上句的具體闡釋，根據(jù)上句中的時間狀語In recent years可知應用現(xiàn)在完成時。 2．mainly　解析：考查詞性轉(zhuǎn)換。句意：它們受歡迎主要是基于簡單的事實。分析句子結(jié)

24、構(gòu)可知，is based on為動詞短語，故用副詞mainly修飾。 3．a(chǎn)bout　解析：考查固定搭配。句意：首先，它們關注社會熱點。care about sth. 為固定搭配，意為“關心，關注……”。故填about。 4．is left　解析：考查動詞的時態(tài)和語態(tài)。句意：盡管有亮點，但是提升的空間也很大。分析句子結(jié)構(gòu)可知，room(空間)和leave為邏輯上的動賓關系，故此處用被動語態(tài)，且句子描述的是一般性事實，時態(tài)與上文保持一致，故用一般現(xiàn)在時的被動語態(tài)。故填is left。 5．educational　解析：考查詞性轉(zhuǎn)換。句意：首先，商業(yè)利益常常超過教育目的，從而引起人們對那些令

25、人無法忍受的廣告的許多抱怨。設空處修飾名詞purposes，應用形容詞修飾。故填educational，意為“有教育意義的”。 6．unbearable　解析：考查詞形轉(zhuǎn)換。句意見上一題解析。根據(jù)句中的complaints可知，該空用bearable的反義詞，在單詞前加前綴un-。 7．though/although/while　解析：考查連詞。句意：除此以外，盡管某些尖銳的評論很吸引眼球，但或許會誤導年輕人。根據(jù)句意，設空處引導讓步狀語從句，可用though，although或while引導。 8．entertaining　解析：考查非謂語動詞。句意：依我看，此類節(jié)目應該承擔更多的責任

26、而不僅僅是娛樂大眾。分析句子結(jié)構(gòu)可知，of為介詞，故用動名詞作賓語。 9．As　解析：考查定語從句。句意：正如所期待的那樣，這些節(jié)目應該在形式和功能上都起積極的作用。本句為as引導的非限制性定語從句，as意為“正如”。類似的結(jié)構(gòu)有：眾所周知(As is known to all...)，正如報道的那樣(As is reported...)等。 10．media　解析：考查名詞單復數(shù)。句意：同時，媒體也應該保護我們社會的價值觀。根據(jù)句意可知此處應用復數(shù)，表示各種媒體，故“媒體”要用復數(shù)media。 Ⅳ.短文改錯 Sunny31st，July It was sunny today and

27、 I was in a good mood.Tired of studying or the noise of city life，I come to the ecology park to enjoy scenery and get relaxing in the afternoon. While I arrived at the park，what came into its sight were the thick green trees.The air was fresh.In addition，I could clearly see a path around the pond.Lying on the grasses decorated with various flowers，I felt with ease because all that I wanted was peace inside. Therefore，with time going by quickly，the sun was setting in the west.So I had to return back home.I would never forget such romantic experience，which was really beyond description.
