【正文】 uler（ 1/8 thick） ， a flat table. Purposes: We?ll show that there is air pressure pushing on us, from every direction while we?re on Earth. Procedure: First put a thin ruler on a flat table with a little less than half of it hanging off the edge of the table （ see the drawing on the right） . Next place a sheet of newspaper over the ruler flat against the table. Make sure to have as little air as possible under the paper so that the fold line of the newspaper is at the ruler. Then quickly strike the end of the ruler hanging off the edge of the table. If you strike it quick enough, the ruler will break near the table edge. What?s going on? The Earth is covered in a layer of air that is nearly 80 miles thick and at sea level exerts or “pushes” hard almost 15 pounds of pressure per square inch. That means that a full sheet of newspaper laid out flat has nearly 9, 300 pounds of air above it. When you break the ruler above, you are able to break it because of the “heavy” air pushing down on the paper while you quickly strike the ruler. At first, the table is pushing back on the paper, and if you move the ruler quick enough, other air around the edges of the paper can?t get under the paper fast enough, so you are trying to lift that 9, 300 pounds with the ruler！ Some air gets under the paper, but not enough, so the ruler breaks. 【 文章大意 】 本文介紹了一個(gè)生活小實(shí)驗(yàn) ， 證明在我們生活的這個(gè)地球上 ， 氣壓無(wú)處不在 。 1. By doing the experiment, we may realize _____ . A. that air exits everywhere B. why there are directions C. that we live with air pressure D. how air helps on Earth 【 解析 】 選 C。 考查細(xì)節(jié)理解 。 文章 Purposes部分直接點(diǎn)明了做這個(gè)小實(shí)驗(yàn)的目的：證明在我們生活的這個(gè)地球上 ， 處處都有氣壓 。 由此判斷選 C。 2. How many steps are there in this experiment? A. 2. B. 3. C. 4. D. 5. 【 解析 】 選 B。 考查細(xì)節(jié)理解 。 從 Procedure中的 First, Next和 Then可知這個(gè)小實(shí)驗(yàn)一共三步 ， 首先將一把很薄的尺子放在桌子上 ， 大約一半的尺子懸在桌子外沿 ， 然后將一張舊報(bào)紙蓋在桌子上 ， 并盡量確保報(bào)紙下面的空氣很少 ， 最后使勁打擊尺子懸空的那頭 ， 如果速度足夠快 ， 那么尺子就會(huì)在沿著桌子的地方被打斷 。 3. The underlined word “exerts” probably means _____ . A. covers pletely B. advocates actively C. influences gradually D. presses heavily 【 解析 】 選 D。 考查猜測(cè)詞義 。 劃線詞所在句子表示 ， 在海平面每平方英寸上面就有大約 15磅的氣壓 ， 再結(jié)合 or后面的“ pushes” hard可知 ， 劃線詞的意思和 D項(xiàng)最接近 。 4. The ruler breaks under a quick strike mainly because of ______ . A. the air pressure on the newspaper B. the heavy weight of the newspaper C. the heavy weight of the flat table D. the strong power used on the ruler 【 解析 】 選 A。 考查推理判斷 。 最后一段解釋了在使勁敲打尺子懸空的那頭時(shí)它會(huì)斷裂的原因 ——報(bào)紙表面的氣壓非常大 。 Ⅴ . 任務(wù)型閱讀 ［ 2020寶雞模擬］ 根據(jù)短文內(nèi)容 ， 從下框的 A~F選項(xiàng)中選出能概括每一段主題的最佳選項(xiàng) 。 選項(xiàng)中有一項(xiàng)為多余項(xiàng) 。 A． Keep yourself energetic with more rest B． Try your best to do more C． Take on tasks one at a time D． Achieve your goal item by item to hit the “sweet spot” E． Think positively about time F． Make an effort to do less In our daily life, we often e across such a situation where piles of affairs are pouring at us so that we have to rush off our feet and even burn the candle at both ends． Thus, we feel extremely stressed． Here fire some pieces of advice for us to deal with the situation． 1． We think we are reducing stress by acplishing （ 完成 ） more than one thing at a time, when in fact, we are causing ourselves more stress than ever． Stressbusting tip: leave multitasking to your personal puter． Do one thing at a time, do it well, and move on to the next item on your list． That?s the best way to regain a sense of control over time． 2． Think for a moment about where in your life you are spending valuable time on something that you could possibly live without． Think about getting away from the TV and puter screens that are mental vampires（ 吸血鬼 ） , sucking the life out of us by stealing our time and attention． By doing less and by carefully choosing which activities give you the least amount of benefit for the time mitment （ 保證 ） they require, you?ll actually end up creating more time in your day． 3． Make a list of four things that you would like to acplish today． Keep the list with you． And stay with each item until you have pleted it． Then go to the next item on your list and repeat the process． Keep doing this until you?ve gotten to the end of your list． Most of us place overwhelming（ 巨大的 ） demands on ourselves, or we expect far too little of ourselves． The goal is to hit the “sweet spot（ 最有效點(diǎn) ） , ” where our expectations of what we can acplish in any given 24 hour period are in line with reality． If you?re afraid that you won?t acplish all four things, well, that?s why they invented tomorrow! 4． Most of us constantly have our fingers on the fastforward button, when we really need to hit the pause button for a while． Every time we add another activity or responsibility to our lives, we generally take the time （ 花時(shí)間 ） for that activity out of our sleep． We can only carry on not sleeping enough for a while before it catches up with us, causing all sorts of health disorders, including a terrible sense of frustration and stress． 5． We all know how weeds can overtake （ 占領(lǐng) ） a garden, so it is our job constantly to notice and uproot any negative thoughts in the garden that is our mind． As a result, positive thoughts can take root, bloom, and create the beauty that we need in order to enjoy our lives to the fullest． If you hear yourself saying, “ I don?t have enough time, ” then say, and preferably out loud, “I have all the time I need for all the things I need to do． ” A declaration（ 宣布 ） like that has a relaxing and liberating effect on every cell in your body, which relieves tension． 答案： 1~5.
