第三部分閱讀理解(共20小題;每小題2分,滿分40分)

閱讀下列短文,從每題所給的A、B、C、D四個選項中,選出最佳答案。

A

David Beckham joined US soccer team LA Galaxy 23 months ago,but less than two years later he is returning to AC Milan.The Italian giants are bringing the England midfielder to Italy on loan(租借)while the US football season is on a break.The deal is a clear signal of Beckham’s intention,who dreams of playing for England at the 2010 World Cup in South Africa.

England manager Fabio Capello had warned his team that anyone not playing over the next few months would not be considered for his team.Beckham is looking to solve the problem by changing Los Angeles for Milan,at least for a few months.

Milan’s current stars――including Kaka,Ronaldinho,Shevchenko and Inzaghi――are excited by Beckham’s joining their ranks.And the move should answer Beckham’s critics,who said that his focus had switched from playing football to making money,that his England career is still his number one consideration.

But it may not be enough.England has a series of promising young players who can play in Beckham’s position.David Bentley,Aaron Lennon and Shaun Wright-Phillips are all competing for a place in the team.

Beckham is well aware that 2010 is his last chance to play at the biggest sporting event on the planet.By moving to AC Milan,even just on loan,he is giving himself every chance of staying in the England team.It seems that he’s not ready to give up lifting the famous trophy yet.

56.How many football teams are mentioned in this passage?

A.One.             B.Two.             C.Three.           D.Four.

57.According to the passage,what does Beckham consider the most important?

A.Money.                                     B.Playing for England.

C.His football career.                     D.Playing in World Cup 2010.

58.Which of the following statements can be inferred from the passage?

A.Soccer players playing for the US can’t join England team.

B.Some of Beckham’s friends hold critical attitudes towards him.

C.World Cup 2010 is Beckham’s last chance to play at the biggest sporting event.

D.Beckham will face fierce competition if he wants to play for England in World Cup 2010.

59.The underlined word in the last paragraph is most probably       

A.a(chǎn) prize got in a competition                  B.a(chǎn) list of the players’ names

C.the responsibility for a player                D.a(chǎn) present given by the coach

Chen Yunlin,president of the Association for Relations Across the Taiwan Straits,visited Taiwan and signed an agreement to open direct shipping,mail and air routes services.

A survey indicated that 75%of the people surveyed were in favor of Chen’s visit Wong Yingru,a university student in Taipei,calls it a breakthrough in cross-Straits relations.She hopes mutual(相互的)recognition of education degrees will be reached soon between the two sides so that young Taiwanese like her will benefit.Last year Wong visited two universities in Fujian and decided to go on with her further study on the mainland.She said,“Compared with Taiwan,the mainland is much large,which often means more opportunities and resources.”

Mainland universities began to accept Taiwanese in 1986.In 2006,the mainla began to recognize the educational degrees issued by Taiwan universities.But mainland degrees still aren’t recognized in Taiwan.This has kept Taiwan students from coming to the mainland.In 2007,a total of 6,568 Taiwan students studied in mainland universities.The number was much lower than the 54,000 students from South Korea and the 18,640 from Japan.Lee Sichen,president of the National Taiwan University,said mutual recognition of degrees will benefit Taiwan universities.“The problem facing many Taiwan umversities is the lack of students caused by the falling birth rate for years in Taiwan.”he said.

Bai Mingran,a student in Beijing said,“In my university,there are exchang programs with American and European universities,but as far as I know,there is none with a Taiwan university.This is contrary to the fact that we share the same origin and should be closer to each other.Taiwan also has good universities.I hope one day 1 can go there.”

64.Why aren’t there many Taiwanese studying in mainland universities?

A.Because they are forbidden to study on the mainland.

B.Because mainland degrees aren’t recognized in Taiwan?

C.Because the mainland doesn’t recognize Taiwan degrees.

D.Because mainland universities provide fewer opportunities for students.

65.What problems are Taiwan universities faced with?

A.The low birth rate.                                   B.The shortage of students.

C.Fewer exchange students.                   D.A lack of educational resources.

66.From Bai Mingran’s words,we can learn

A.her university in Beijing is not a good one

B.she once studied in an American university

C.she wants more exchanges with students from Taiwan

D.her university has a closer tie with a Taiwan university

67.Which of the following is true according to this article?

A.Taiwan began to accept the mainland students in 2006.

B.The mainland recognized Taiwan educational degrees in 1986.

C.Compared with Japan,more Korean students study on the mainland.

D.Only after visiting mainland universities will many Taiwanese decide to study on the                                       mainland.

      高三化學(xué)攻關(guān)三十六法之――守恒法

       

      守恒法是高考中?汲S玫囊环N解題方法。系統(tǒng)學(xué)習(xí)守恒法的應(yīng)用,對提高解題速率和破解高考難題都有很大的幫助。

      ●難點(diǎn)磁場

      請試做下列題目,然后自我界定學(xué)習(xí)本篇是否需要。

      現(xiàn)有19.7 g由Fe、FeO、Al、Al2O3組成的混合物,將它完全溶解在540 mL 2.00 mol?L1的H2SO4溶液中,收集到標(biāo)準(zhǔn)狀況下的氣體8.96 L。已知混合物中,F(xiàn)e、FeO、Al、Al2O3的質(zhì)量分?jǐn)?shù)分別為0.284、0.183、0.274和0.259。欲使溶液中的金屬陽離子完全轉(zhuǎn)化為氫氧化物沉淀,至少應(yīng)加入2.70 mol?L1的NaOH(aq)體積是________。

      ●案例探究

      [例題]將 CaCl2 和 CaBr2 的混合物 13.400 g溶于水配成 500.00 mL 溶液,再通入過量的 Cl2,完全反應(yīng)后將溶液蒸干,得到干燥固體 11.175 g。則原配溶液中,c(Ca2)∶c(Cl)∶c(Br)為

      A.3∶2∶1                   B.1∶2∶3                    C.1∶3∶2                    D.2∶3∶1

      命題意圖:考查學(xué)生對電荷守恒的認(rèn)識。屬化學(xué)教學(xué)中要求理解的內(nèi)容。

      知識依托:溶液等有關(guān)知識。

      錯解分析:誤用電荷守恒:

      n(Ca2 )= n(Cl) + n(Br),錯選A。

      解題思路:1個 Ca2 所帶電荷數(shù)為2,則根據(jù)溶液中陽離子所帶正電荷總數(shù)等于陰離子所帶負(fù)電荷總數(shù),知原溶液中:

      2n(Ca2) = (Cl) + (Br)

      將各備選項數(shù)值代入上式進(jìn)行檢驗可知答案。

      答案:D

      ●錦囊妙計

      化學(xué)上,常用的守恒方法有以下幾種:

      1.電荷守恒

      溶液中陽離子所帶正電荷總數(shù)等于陰離子所帶負(fù)電荷總數(shù)。即:陽離子物質(zhì)的量(或濃度)與其所帶電荷數(shù)乘積的代數(shù)和等于陰離子物質(zhì)的量(或濃度)與其所帶電荷數(shù)乘積的代數(shù)和。

      2.電子守恒

      化學(xué)反應(yīng)中(或系列化學(xué)反應(yīng)中)氧化劑所得電子總數(shù)等于還原劑所失電子總數(shù)。

      3.原子守恒

      系列反應(yīng)中某原子(或原子團(tuán))個數(shù)(或物質(zhì)的量)不變。以此為基礎(chǔ)可求出與該原子(或原子團(tuán))相關(guān)連的某些物質(zhì)的數(shù)量(如質(zhì)量)。

      4.質(zhì)量守恒

      包含兩項內(nèi)容:①質(zhì)量守恒定律;②化學(xué)反應(yīng)前后某原子(或原子團(tuán))的質(zhì)量不變。

      此外,還有物料平衡,將編排在第16篇――水的電離中。
