2．Number sense is not the ability to count．It is the ability to recognize a（16）C in number．Human beings are born with this ability．（17）B，experiments show that many animals are，too．For example，many birds have good number sense．If a nest has four eggs and you remove one，the bird will not（18）D．However，if you remove two，the bird（19）Aleaves．This means that the bird knows the （20）Cbetween two and three．
Another interesting experiment showed a bird's（21）Anumber sense．A man was trying to take a photo of a crow（烏鴉）that had a nest in a tower，but the crow always left when she saw him coming．The bird did not（22）Duntil the man left the tower．The man had an（23）C．He took another man with him to the tower．One man left and the other stayed，but they did not（24）B the bird．The crow stayed away until the second man left，too．The experiment was（25）Dwith three men and then with four men．But the crow did not return to the nest until all the men were（26）B．It was not until five men went into the tower and only four left that they were（27）D  able to fool the crow．
How good is a human's number sense？It's not very good．For example，babies about fourteen months old almost always notice if something is taken away from a （28）B group．But when the number goes beyond three or four，the children are（29）Dfooled．
It seems that number sense is something we have in common with many animals in this world，and that our human （30）C is not much better than a crow's．

分析 人類天生就具有數(shù)字的能力，這是一種識別變化的能力，科學(xué)家發(fā)現(xiàn)動物也具有類似的能力．

解答 CBDAC  ADCBD  BDBDC
16．C考查動詞．根據(jù)下文的"remove one/two"語義提示可知，這里是把數(shù)字發(fā)生變化；四個選項分別為：A"上升"，B"圖案"，C"改變"，D"趨勢"，由此可知本句含義為"數(shù)字感是分辨數(shù)字變化的能力"，故C為正確答案．
17．B考查副詞．根據(jù)上下文的語境可知，分別說到"人類與生俱來具有這種能力（分辨數(shù)字變化的能力）"和"很多鳥類也有很好的數(shù)字感．"，運用邏輯推斷可知，這里表示這是"令人驚訝的是"，四個選項分別為：A"重要的是"，B"令人驚訝的是"，C"令人失望的是"，D"幸運的是"；所以答案為B．
18．D考查動詞．根據(jù)上文第一句的"recognize"和下文的"knows the 5"語義提示可知，這是這二個詞的同義詞復(fù)現(xiàn)，本句句義為：如果一個鳥窩里有四顆鳥蛋，你拿走一個，鳥兒不會發(fā)現(xiàn)．A"生存下來"，B"關(guān)心"，C"孵（蛋）"均不符合語境．
19．A考查副詞．根據(jù)常識判斷，這里要表達(dá)的意思是：如果取走兩顆鳥蛋時，鳥類在通常情況下會離開（飛走）．四個選項分別為：A"通常，一般情況下"，B"真誠地"，C"隨意地"，D"故意地，有意地"．
20．C考查名詞．根據(jù)上文說到的"拿走一個和二個鳥蛋時，鳥的反應(yīng)和表現(xiàn)"的語義提示可知，這些都是屬于difference的范疇．而且這里的difference與第二句中的change形成同義詞復(fù)現(xiàn)的關(guān)系；四個選項分別為：A"距離"，B"范圍"，C"不同，區(qū)別"，D"間隙（時段）"．本句句義為：這說明鳥類知道二和三的區(qū)別．
21．A考查動詞．根據(jù)上下文的語義提示可知，這里要表達(dá)的意思是：另一個有意思的實驗也顯示了鳥類的這種令人驚奇的數(shù)字感．故答案為A．a(chǎn)mazing與第四句空格2"Surprisingly（令人吃驚或驚奇的是）"構(gòu)成同義詞的復(fù)現(xiàn)關(guān)系．
22．D考查動詞．根據(jù)下文第十一空前"not return to the nest"的語義提示可知答案，四個選項的含義分別為：A"放松"，B"恢復(fù)"，C"反應(yīng)"，D"返回，歸還"．本句句義為：這只鳥直到那個人離開那座塔之后才離開．事實上這里的return與上句中的left形成反義詞的復(fù)現(xiàn)關(guān)系．
23．C考查名詞．根據(jù)上下文的語境可知，這個人第一種方法行不通，所以這里再用另一方法，由此運用邏輯推斷可知，這里要表達(dá)的意思是：這個人有（或想出）了一個主意，四個選項的含義分別為：A"失望"，B"借口"，C"主意，想法"，D"解釋"．根據(jù)語境，下文講了他的具體做法．A、B和D都不符合，C為正確答案：先有了想法或主意，然后是具體的行為．
24．A考查動詞．由but可知，他們并沒能"欺騙"那只烏鴉．與下文fool？the？crow中的fool是原詞復(fù)現(xiàn)，也就是說從此可以得到啟示．
25．B考查動詞．根據(jù)上下文的語義提示可知，本句講了實驗的進(jìn)展：他們又先后用三個人和四個人重復(fù)做了實驗．并在下句交代了實驗的結(jié)果：但是烏鴉都是等到所有人（離開）后才回巢．
四個選項的含義分別為：A"報道"，B"重復(fù)"，C"設(shè)計"，D"通過"．根據(jù)語境，
26．B考查形容詞．根據(jù)語義提示可知，gone與上文（本段）的left，return，left，left多次構(gòu)成同義詞或反義詞的復(fù)現(xiàn)關(guān)系．所以答案選B項．句意為表示兩次實驗的結(jié)果：但是烏鴉都是等到所有人（離開）后才回巢．故答案為B"離開"．其他選項的含義分別為：A"感到困惑"，C"感到很累"，D"喝醉了酒"．
27．D考查名詞．根據(jù)上下文語境并運用邏輯推斷可知，本句以強調(diào)句的形式交代了，最后的一次實驗及實驗結(jié)果：直到五個人進(jìn)入到塔中，只有四個人離開時，他們才最終把烏鴉給搞糊涂了/愚弄了烏鴉．其他錯誤選項的含義分別為：A"逐漸地"，B"幸運地"，"奇怪地"．
28．B考查形容詞．根據(jù)本段語境并結(jié)合常識可知，前兩句在說：人類的數(shù)字感覺也不是非常好．再根據(jù)大語境，全文一直在講，對于鳥類在小數(shù)字變換時的數(shù)字分辨能力的實驗．顯然可以推出本句句義為：例如，當(dāng)從一個很小的一組東西中拿走一些時，十四個月大的嬰兒幾乎總是能夠注意到（這個變化）．故答案為B．其他錯誤選項的含義分別為：A"單一的"，B"當(dāng)?shù)氐?，D"新的"． 這里的small與以上的數(shù)字均形成具體與概括的復(fù)現(xiàn)關(guān)系．
29．D考查副詞．根據(jù)語義提示可知，這里的often與第三句中的almost形成近義詞復(fù)現(xiàn)關(guān)系．四個選項的含義分別為：A"很少"，B"臨時"，C"只有"，D"常常"．根據(jù)語境與行文邏輯，本句句義為：但是當(dāng)數(shù)字超過三或者四時，嬰兒們通常會被搞糊涂．
30．C考查名詞．根據(jù)上文的語義提示可知，這里的ability與首段的ability形成相同詞的復(fù)現(xiàn)關(guān)系．文章末段與首段開甩語義照應(yīng)上的前后照應(yīng)的關(guān)系．四個選項的含義分別為：A"視力，看見"，B"本質(zhì)，天性，內(nèi)在"，C"能力"，D"信仰，相信"．本段為結(jié)論段，根據(jù)語境，本句句義為：（好像數(shù)字感是我們與世界上的許多動物都具備的能力，而且）我們?nèi)祟惖倪@種能力不比烏鴉更強．

點評 考生須靈活運用語法知識，如單詞詞性、單詞時態(tài)、名詞單復(fù)數(shù)、連接詞、代詞、冠詞等判斷各空白處應(yīng)填寫的內(nèi)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

17．One of the first things you will notice about Britain is that they drive on the left，and the steering wheel is on the right．This causes a strange feeling，but driving on the left is not as unusual as you might think； about a quarter of the countries in the world drive on the left．Most of them are former British colonies like Australia，Sou th Africa，and Ireland，but Thailand，Japan and Indonesia also do so．This driving habit is strange to us，but there is a perfectly good reason for it：up till the late eighteenth century，everybody traveled on the left-hand side of the road because it was the best way for mostly right-handed people to protect themselves in violent societies．So when strangers passed the road，they walk on the left to make sure that their sword arm was between them．
After the French revolution in 1789，however，the French government changed sides as part of a great social reorganization．Later，Napoleon，the ruler of France，spread the change to the rest of the continental Europe．He did this because he was left-handed himself，and he wanted his armies to march on the right so that he could keep his left arm between himself and any enemy．From then on，any part of the world which became part of the British Empire marched on the left，and any part controlled by the French marched on the right．
After the American Revolutionary War （1775-1783），the US became independent and decided to make traffic drive on the right in order to cut its ties with Britain．Once America became the center of the car industry，if you wanted a good car，you bought an American-made right-hand drive vehicles．From then on many countries changed out of necessity．
Today，the EU would like Britain to be the same as the rest of Europe，but this is no longer possible．It would cost billions of pounds to change everything round．The last European country to convert to driving on the right was Sweden in 1967，but there were far fewer cars there，and the population was much smaller．
21．Why did people travel on the left before the late 18th century？A
A．They could be safer from attacks．
B．The government required them to do so．
C．There were more left-handed people back then．
D．They could prevent strangers passing by their left side．
22．What was Napoleon's attitude to walking on the left？C
A．Negative．B．Indifferent．
C．Supportive．D．Uncertain．
23．For Americans，driving on the right was a way to showD．
A．the connection with France was broken
B．the American Revolutionary War had ended
C．America was the center of the car industry
D．the US was no longer controlled by the UK
24．The underlined phrase"convert to"in the last paragraph meansC．
A．insist on                              B．give up
C．change into                            D．disagree with．

12．Tom was a clever boy，but his parents were poor，so he had to work in his spare time and during his holidays to pay for his education．In spite of this，he managed to get to university，but it was so expensive to study there that during the holiday，he found it necessary to get two jobs at the same time so as to make enough money to pay for his studies．
One summer he managed to get a job in a butcher's（屠夫） shop during the daytime，and another in a hospital at night．In the shop he learned to cut meat up quite nicely，so the butcher often left him to do all the serving while he went into a room behind the shop to do the accounts（算賬）．In the hospital，on the other hand，he was，of course，allowed to do only the simplest jobs，like helping to life people and to carry them from one part of the hospital to another．Both at the butcher's and at the hospital，Tom had to wear white clothes．
