答案：A

題干分析：題干沒(méi)有出現(xiàn)轉(zhuǎn)折的意思.先說(shuō)文藝復(fù)興后用的是七個(gè)音階,第一段粗體字說(shuō):一殘缺笛子有4個(gè)洞，大

概排列順序與7音階比較搭.接著說(shuō)應(yīng)該有更多洞，而完整笛子確實(shí)是更長(zhǎng)的.第二段粗體說(shuō):笛子很可能用的就是

7個(gè)音階(有7個(gè)洞).

選項(xiàng):由于題干無(wú)轉(zhuǎn)折，全是支持，所以選項(xiàng)中第二句話出現(xiàn)反對(duì)的都錯(cuò)，排除BDE,比較AC的第-句話(的第一句

也是反對(duì)的，意思是:第一句削弱了一個(gè)整段都反對(duì)的立場(chǎng),無(wú)中生有.

選A

難度評(píng)級(jí)：三星(閱讀有一定難度，理解了邏輯上很簡(jiǎn)單)

解題關(guān)鍵:抓住題干的態(tài)度，是否有轉(zhuǎn)折，是否有反對(duì)等，細(xì)節(jié)上無(wú)需過(guò)分追究.

題干分析:犀牛會(huì)掉collar,掉了裝回去需要用鎮(zhèn)定劑.發(fā)現(xiàn)那些總是被裝回collar的母犀牛繁殖力低.結(jié)論:鎮(zhèn)定劑

中某些物質(zhì)阻礙繁殖.

要求評(píng)估.

選項(xiàng)：

A、比較未安裝radiocollar和已安裝radiocollar的雌性犀牛的數(shù)量誰(shuí)多誰(shuí)少——沒(méi)有提到生育力，所以無(wú)

關(guān)

B、比較犀牛和其他的大型動(dòng)物關(guān)于使用鎮(zhèn)定劑的不同——沒(méi)有提到生育能力，且文中并未出現(xiàn)大型動(dòng)物，完

全無(wú)關(guān)

C、翻譯：除了給犀牛安裝radiocollar這個(gè)原因之外，parkranger給犀牛注射鎮(zhèn)定劑以致它們失去行動(dòng)力

需要重裝collar的犀牛由于注射鎮(zhèn)定劑，所以聽(tīng)話.其它犀牛就是不聽(tīng)話，對(duì)不聽(tīng)話犀牛的辦法就是單獨(dú)抓出來(lái)，

注射1.2倍鎮(zhèn)靜劑.如此一來(lái)，重裝collar的犀牛實(shí)際上是使用鎮(zhèn)靜劑最少的犀牛了.結(jié)論自然就不確定了.

D、比較雄性犀牛和雌性犀牛的radiocollar掉落率——沒(méi)有提到生育能力，且結(jié)論并未提到雄性犀牛，無(wú)關(guān)

E、radiocollar是不是唯一的能夠使人們追蹤到犀牛的唯一實(shí)用方法一跟結(jié)論中的鎮(zhèn)定劑和生育力之間的

題干分析:說(shuō)稅漲了8%,煙銷量降了10%.而稅漲前，煙銷量降了1%.結(jié)論:香煙銷量與稅后煙價(jià)密切相關(guān).問(wèn)加強(qiáng)

選項(xiàng)：

A.若第2年銷量大漲，可能是其他原因.未提到稅后煙價(jià).

B.消費(fèi)者得到的吸煙對(duì)于健康危害的信息在增加稅前，稅后沒(méi)有改變。改變的只有香煙的價(jià)格，所以是價(jià)格影

響sales.這是典型的他因排除來(lái)加強(qiáng).

C.消費(fèi)者不知道稅的增加。但這個(gè)稅后煙價(jià)是實(shí)實(shí)在在漲了，消費(fèi)者以為是稅漲或者是煙漲渚B不影響結(jié)論.

D.香煙價(jià)格增加，通貨膨脹，人們收入減少。這可能是銷量下降的一個(gè)原因,削弱了是因?yàn)槎惡鬅焹r(jià)上漲這個(gè)原

因.

E.香煙種類增加，和題目無(wú)關(guān),排除.

題干分析:說(shuō)有一地區(qū)的很多店要關(guān)門，因?yàn)槊媾R某NB新店的挑戰(zhàn).曾經(jīng)有一次，該地區(qū)很多店關(guān)門了但又振作了.

可這一次，期盼該地區(qū)重新振作缺乏根據(jù),因?yàn)椋?/p>

選項(xiàng)分析：

A正確.旗艦店會(huì)直接面臨挑戰(zhàn)并慘敗,而原來(lái)帶領(lǐng)該地區(qū)重新振作的就是這些旗艦店.

B,說(shuō)交通的，無(wú)關(guān)選項(xiàng)

C,無(wú)關(guān)選項(xiàng)，說(shuō)當(dāng)時(shí)重振時(shí),破產(chǎn)的店被同類店所接手.

D,說(shuō)NB店準(zhǔn)備在前5年薄利多銷.不管它怎么銷，打擊是不變的.

E,可以想象地區(qū)不會(huì)全完蛋,而是嚴(yán)重萎縮.這是說(shuō)明東山再起的可能性有，但很小.

選A

星級(jí)評(píng)級(jí):三星

解題關(guān)鍵:看完題干，就明確需要找一個(gè)選項(xiàng)，說(shuō)這次的打擊不同于前,而使得該地區(qū)無(wú)法再次振作.這樣E就不符

合邏輯，除非題目告訴你說(shuō)，如果?個(gè)地區(qū)全完蛋了才更有利于重新規(guī)劃重新振作，因?yàn)檫@樣就不會(huì)有那些萎縮的

企業(yè)礙手礙腳，你才能選E.

來(lái)的稅都繳了。

問(wèn)哪一項(xiàng)能support這個(gè)政策可以起到刺激long-termsavings

B.大部分選擇該免稅賬戶的人都會(huì)在65歲之前把錢取出。削弱。

C.大部分市民會(huì)在65歲之前把錢存入該免稅賬戶。加強(qiáng)，正確。加強(qiáng)了原文中的前提，即市民必須在65歲

之前一直儲(chǔ)蓄。

D.在計(jì)劃完成的前十年，市民會(huì)在長(zhǎng)期儲(chǔ)蓄賬戶里增加年收入一定比例的儲(chǔ)蓄額。無(wú)關(guān)。文章講的是免稅賬戶,

答案：C

題干分析：人類遷徙和氣候變暖都可能導(dǎo)致物種滅絕。問(wèn)，哪個(gè)能夠說(shuō)明是人類遷徙而非氣候變暖導(dǎo)致滅絕，

即要滿足兩個(gè)條件：1、人類遷徙導(dǎo)致滅絕；2、氣候變暖不導(dǎo)致滅絕

選項(xiàng)分析：

A、有些物種在人類進(jìn)入以后依然可以生存，這是說(shuō)明氣候變暖是主要原因的，排除！

B、氣候變暖的時(shí)候，很多物種滅絕了，這也是說(shuō)明氣候變暖是主要原因的，排除！

C、很多物種生存下來(lái)了，而這些物種生活的地點(diǎn)是經(jīng)歷了氣候變暖但沒(méi)有人進(jìn)入的，剛好和要求符合，對(duì)啦！

D、說(shuō)只有一些人類學(xué)家發(fā)現(xiàn)，物種的滅絕和人類的進(jìn)入好像有一些聯(lián)系。首先，“只有一些”就說(shuō)明這個(gè)證據(jù)

是不足的；其次，沒(méi)有提到氣候的問(wèn)題，不對(duì)！

E、一些物種在人類進(jìn)入之前就滅絕了，這說(shuō)明人類不是主要原因，排除！

題干分析：科學(xué)家超過(guò)40歲一般就沒(méi)有重大創(chuàng)新了，所以有人說(shuō)啊，年齡增長(zhǎng)會(huì)導(dǎo)致創(chuàng)新能力下降。這是第

B、是否科學(xué)家在選項(xiàng)時(shí)會(huì)受到信念的影響，無(wú)關(guān)項(xiàng)，排除！

C、是否40歲以上的科學(xué)家在其他活動(dòng)中獲得更多滿足，能夠解釋為啥40歲之創(chuàng)新少，但是不能否定和領(lǐng)域

時(shí)間的關(guān)系，片面，排除！
