【題目】閱讀理解
Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time — about eight hours after you wake up — your body temperature goes down. This is what makes you slow down and feel sleepy.
Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer(遭受) less from problems such as heart disease. Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it!
If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap — even ten minutes of sleep can be helpful.
(1)Why do you sometimes feel sleepy in the early afternoon?
A.Because it's very hot in summer.
B.Because you eat too much for lunch.
C.Because you didn't have a good sleep last night.
D.Because your body temperature goes down at that time.
(2)What advice does the writer give on taking a nap?
A.If your time is limited, a short nap can also help.
B.Only people in warmer climate need to take a nap.
C.You'd better take a nap about an hour after you have lunch.
D.You can sleep as long as you like so that you won't feel tired or sleepy.
(3)What can we learn about "naps" according to the third paragraph?
A.Doctors need to take naps while employers don't.
B.Taking naps is helpful for people's health in spring and summer.
C.If you take naps every day, you'll have less risk of heart disease.
D.All the people in warmer climates take naps in the middle of the day.
(4)What can we infer(推斷) from the passage?
A.You will feel less sleepy if you sleep for a long time.
B.Taking a nap whenever you want will do good to your health.
C.If you get up at 6:30 am, you'd better take a nap at about 2:30 pm.
D.Sleeping for eight hours and you'll feel sleepy a short period later.
(5)What would be the best title for the text?
A.Just For a Rest.
B.All For a Nap.
C.A Special Sleep Pattern.
D.Taking Naps in Warmer Climate.

【題目】閱讀以下材料,完成問題:
材料1:西沙群島、南沙群島、中沙群島、東沙群島分布在我國遼闊浩瀚的南海海洋上,是中國南海諸島的主要組成部分。其中曾母暗沙是中國領土最南端,其緯度大約是4°N。
材料2:南海諸島自古以來就是中國的神圣領土,據(jù)考古發(fā)現(xiàn),在西沙群島的甘泉島有一處唐宋遺址,出土了一批唐宋瓷器、鐵鍋殘片以及其他生產(chǎn)、生活用品。這無可辯駁地證明。至少從唐宋時期開始,中國人民就已經(jīng)在西沙群島居住和生產(chǎn),早已經(jīng)是西沙群島的主人。事實證明,中國人民是最早發(fā)現(xiàn)南海諸島的,長期以來在南海諸島的島嶼、礁灘上進行漁業(yè)捕撈,對這些島嶼、礁灘進行辛勤的開發(fā)和經(jīng)營。南海諸島及附近的近海海域海底資源十分豐富,尤其是海底石油和天然氣儲量巨大,中國地質(zhì)學家認為,南沙群島的曾母暗沙盆地是南海石油和天然氣開發(fā)最好的地區(qū)之一。石油儲藏量約200億噸,有“第二個波斯灣”之稱。同樣,西沙群島、中沙群島及附近海域也有上千米的新生代沉淀物,這些沉淀物與中國北部灣、海南島的新生代沉淀物有密切的聯(lián)系。因此也是大有希望的海底石油和天然氣產(chǎn)地。另外,南海諸島及附近還蘊藏著豐富的金屬礦產(chǎn)資源,我們相信,隨著科技的進步和海洋開發(fā)的深入,南海的自然資源一定有著非常廣闊的開發(fā)前景和巨大的利用價值。
材料3:最近一段時間,在中國南海海城,圍繞國家海洋權益的紛爭愈演愈烈。很多的媒體,包括一些專家學者,甚至眾多軍事愛好者,紛紛針對這一話題,發(fā)表自己的一些看法和見解。其實維護國家海洋權益,從手段和方法上來說,不是一個單一的問題。維護國家海洋權益,需要多種的手段和方法。從總體上,應該至少包括五個方面的內(nèi)容。第一,要有堅定的國家決心。海上權益涉及到國家的主權和核心權益。第二,維護國家海洋權益,需要有雄厚的經(jīng)濟和技術基礎。第三,維護國家的海洋權益,還需要在所擁有的海城上進行有效管理。第四,因為歷史問題造成的相對復雜的海上權益紛爭,就需要有一個靈活的外交手段。第五,除了上述幾點外,維護國家海洋權益,最根本的,最后的 一道保險就是海上力量。
(1)南海諸島自古以來就是中國的固有領土,南海諸島有哪些群島組成?中國領土最南端曾母暗沙的緯度大約是多少?
(2)捍衛(wèi)國家主權和保護國家權益,我們應該怎么做?
