Passage One
Coasts mark the area where dry land meets oceans or other large bodies of water．They are one of the most active environments found on Earth．The coasted landscape is ever changing． It reflects the conflicting processes erosion of and deposition．It is a landscape that is affected by the interac-tions of the Earth，the Moon，and the Sun．
Coasts are among the most beautiful and inspiring landscapes on the planet，whether they are scenes of torrential storms or serene calm．Throughout recorded history，humans have sought to live on or near coasts． Although coasts account for only lo percent of Eaah’s land surface，they serve as home to tw0．thirds of the world’s human population．
Coasts and shore．coastline and shoreline，are commonly used in place of each other．Techni- cally，they are different areas along a coastal hmdscape．The line that marks‘the boundary between water and land is the shoreline． It constantly fluctuates because of the regular action of waves and tides．The shore is that strip of ground borderi ng a body of water that is alternately covered or ex- posed by waves or tides：The boundaries of the shore are marked by the shoreline at its farthest sea-ward(10w tide)and farthest landward(high tide)．
Tides is the Deriodic rising and falling of water in oceans and other large bodies of water in re- sponse to the gravitational attraction of the Moon and the Sun upon Each．Although the Sun is larger than the M00n．the Moon is closer to Earth and，therefore，its gravitational force is approximately2．2 times greater．The gravitational pull of the Moon creates two types of tides：high and low．A tidal bulge occuYs in the oceans on the side of Each nearest the Moon，at the same time，a second tidal bulge occurs on the opposite side of Earth．This second bugle forms because the force of the Moon’s gravity pulls the solid body of Eaah slightly away from the water on Eaah’s far side．These bugles are high tides．The areas between the tidal bugles experience low tide．
As Earth rotates．the tides move over its surface．It takes approximately 24 hours and 50 mi-nutes for a given point on Earth to make a complete cycle relative to the Moon，and two lunar tidal cvcles occur during this time．Thus，the average time between high tides is 1 2 hours and 25 mi-nutes．This is a generalized explanation of titles．They do not move evenly and predictably over Earth’s surface．Variations in the depth of the oceans and the distribution of landmasses combine with other factors to produce highly complex tidal behavior．
The coast and coasdine begin where the shore ends at its high tide mark(farthest landward)．The line between the coast and the shore at high tide is the coastline．The coast extends landward from the coastline to the first major change in terrain features，which may be miles inland．This could be a highland or a forest or some other type of terrain．Sometimes，the change between the coast and the adjacent terrain is not so distinct．
21．All of the following statements ale true about coastal landscape EXCEPT__________．A．It is an area of stagnancy．
B．It is an area of continuous change．
C．It is an area of erosion and deposition．
D．It is an area shaped by the interaction of the Earth，the Moon，and the Sun．22．How many people live on or near coasts?
A．About lo percent of human population．
B．About 25 percent of human population．
C．About 67 percent of human population．
D．About 75 percent of human population．
23．The underlined word fluctuate in Paragraph 3 is closest in meaning to__________．A．forecast
B．alter
C．stable
D．strike
24．The gravitational force of the Sun and the Moon upon Earth depends on__________．A．their size
B．their weight
C．their distance to Earth
D．the depth of the oceans
25．One lunar tidal cycle lasts__________．
A．24 hours and 50 minutes
B．12 hours and 25 minutes
C．a month
D．haIf a month

完成第26—30小题。

Passage Two
Respect is not included in the marriage VOWS．No illustrated books show how to achieve it．Andyet it is central to a lastin9，satisfying marriage．
What is this thing called respect?It is not the same as admiration．“When you fall in love，you admire the other．”says Dr．Alexander Symonds，associate clinical professor of psychiatry at theNew York University School of Medicine，“You look up to someone--much the way a child idealizesa parent．”
Such romantic admiration thrives and even depends on the il lusion that hi；or she
is“perfect for you．”That’s why it doesn’t last．You come to see that the person you married isn’t exactly what you expected，”says Francine Gaborone，“There are differences of personality，of approaches tolife，‘different ways of doing things．”You can try to change your mate back into your fantasy． But for the marriage to last and growit’s better to agree to disagree，to learn to let each other be．Only by taking this path Call you beginto develop real respect toward each other．
“I have one patient whose husband loves sports，especially tennis，”says Dr．Symonds．“Shewould prefer to go to the theatre，or to stay at home and read．She could simply say，‘We have dif-ferent tastes．’Instead，she says，‘How can he waste his time and money that way?’She puts himdown．”
The put-down is the chief symptom--and weapon--of lack of respect，or contempt．“Contemptis the worst kind of emotion．”says Symonds．“You feel the other pemon has no worth．”
We’ve aU seen maITiages in which one or both partners attack the other quite savagely in the guise of“It，s for your own good．”Any“good”is undone．by the hostile tone．A wife nags her hus-band to be more ambitious and makes him feel like a failure because he prefers craftsmanship orcommunity pmjects to the competitive business world．Or a husband accuses his wife of wasting time whenever she gets together with a friend：“Why isn’t she doing something productive?”
In good marriage partners nurture each other’s self-esteem．They may experience humorous incomprehension of one another’s preferences，but they never make their loved person feel like an idiot．“Martyr’s idea of a vacation is to go down to basement on a sunny day and spend time wood-working，”says Dr．Alexander Symonds of her husband，psychiatrist and surgeon Martin Symonds.
But there’s fondness in the gibes and firm support for the other’s right to be himself．Respect is expressed in words like，“Sure，I’11 come with you．Just don’t be mad if I fall asleep.”
That’s the paradox of a good marriage：only by respecting each other as you are do you oPenthe doorto change．The root meaning of the word respect is“to look at"．Respect is a clear yet lov-ing eye．It sees what i8陀ally there，but it also sees what is potentially there and helps bring it tofruition． Respect is the art of love by which married couples honor what is unique and best in each other．26．According to the author。

respect__________.
A．means accepting each other’s faults
B．means valuing each other’s differences
C．should be included in the marriage VOWS
D．is as important to a satisfying marriage as admiration
27．According to the author，which of the following is the most harmful to a marriage? A．Admiration of your partner．
B．Idealization of your partner.
C．Contempt of your partner．
D．Disillusion of your partner.
28．The underlined phrase agree to disagree in Paragraph 4 means that__________. A．one should realize that no two people are the same
B．one should be keen to find out his or her partner’s merits
C．one should face the reality that his or her partner is not a perfect person D．one should realize that lle or she should appreciate differences on the part of this or her partner
29．The passage suggests that i f you respect your partner，you will__________. A．help him or her to improve
B．change yourself to tolerate h．im or her
C．change him or her into what you expect
D．show your incomprehension of his hobbies in a humorous way
30．The underlined word undone in Paragraph 7 suggests that__________.
A．what you said reversed what you meant
B．what yotI said was not what you meant
C．what you said meant nothing to your partner
D．what you said failed to touch the heart of your partner

教学时间：45分钟
学生概况：某城镇普通中学八年级(初中二年级)学生，班级人数40人。

多数学生已经达到《义务教育英语课程标准(201 1年版)》三级水平。

学生课堂参与积极性一般。

语言素材：
1．A[解析]River Ganges“恒河”，属于江河湖海这一类名词，故前面要加定冠词the，所以选择A项。

2．D[解析]本题考查的是现在完成时的用法。

This is／was the first(second，
third．…)time that．．．结构，后面的谓语动词要用现在完成时／过去完成时。

3．B[解析]本题句意为：凯利喜欢唱歌，而她的双胞胎妹妹喜欢跳舞。

while在此作连词，表示对比，意为“然而”。

故选择B项。

4．C[解析]本题句意为：作为死者的直系亲属，她继承遗产是合法的。

A项意为“可选择的”；B项意为“义务的”；C项意为“合法的，正当的”；D项意为“突出的，显著的”，
5．A[解析]本题句意为：damp和moist的词汇关系是同义关系。

A项意为“同义关系”：B项意为“反义关系”；C项意为“上下位关系”；D项意为“同音异义”，damp和moist 都有“潮湿的”之意，所以选择A项。

6．D[解析]本题句意为：美国议会中制定法律的模式有很多的弊端，但没人设法去改进。

A项意为“选择”；B项意为“解决方案”；C项意为“优势，特点”；D项意为“缺点，弊端”，所以选择D项。

7．A [解析]A项所有音标都是清辅音。

9．D[解析]A项意为“教育学”；B项意为“心理学”；C项意为“社会学”；D项意为“神话学”，“神话学”是指关于神话故事的科学研究，与二语学习无关，所以选择D项。

10．C[解析]题干的意思是：以下哪一个属于口误?A、B、D三项都不是口误，C项想表达的是黑色的盒子，即black boxes，属于口误，所以选择C项。

11．A[解析]演绎法是英语语法教学中常用的一种方法，一般是老师写出很多例句，然后引导学生分析语法规则。

A项意为“演绎法”；B项意为“描述法”；C项意为“巩固法”；D项意为“归纳法”。

所以选择A项。

12．B[解析]A项意为“词汇上”；B项意为“语篇上”；C项意为“故事上”；D项意为“语法上”，根据题干表述可知，通过apology(道歉)／acceptance(接受)，inform(通知)／ac-knowledge(收到)的例子来集中探讨“言语功能”以及“期待反应”时，属于语篇的教学。

所以选择B项。

13．C[解析]“管理”不是用已知词汇解释新词汇的一种手法。

听前活动指的是在听材料之前让学生做好听音准备的各种教学活动。

写一篇相关的文章，时间太长，不属于听前准备活动。

所以选择A项。

16．B[解析]A项意为“激励性写作”；B项意为“指导性写作”；C项意为“自由写作”；D项意为“创造性写作”。

写作练习，例如完整的范丈，复制，压缩，转化，这些主要都是指导性写作中会用到的练习步骤。

17．A[解析]根据题干表述可知，该教师只强调了表述的准确性，而没有对学生提供的其他信息作出应有回应。

所以选择A项。

18．D[解析]D项“虽然你没有答出要点，但是我很高兴听到其他的观点”，符合文意，所以选择D项。

19．D[解析]A项意为“重铸，彻底改动”；B项意为“修正，修改”；C项意为“积极反馈”；D项意为“推迟反馈”。

根据题干表述可知，老师只是让学生再说一遍，而没有对学生的答案给予评价和纠正，显然学生的回答是存在错误的，这种现象属于“推迟反馈”。

20．A[解析]A项意为“引导”；B项意为“观察”；C项意为“监督”；D项意为“评价”。

学生在参与小组活动时，教师在四周走动，必要时可以提供帮助，以确保学生们正确地完成任务，这种方式是“引导”。

所以选择A项。

21．A[解析]根据文章第一段最后三句话可以判断选项B、C、D是正确的。

选项A表达的意思是海岸景观是停止不动的，与文中表达意思矛盾，所以A项不正确。

22．C[解析]根据文章第二段最后一句中的tw0．thirds判断，大约67％的人住在沿海地区或临近海的地区。

23．B[解析]题干中的fluctuate意为“波动，涨落”。

A项意为“预报，预测”；B项意为“改变，更改”；C项意为“稳定的，牢固的”；D项意为“打，撞击”。

其中与题干表述近义的是B项。

24．C[解析]根据文章第四段中的第二句“Although the Sun is largerthan the Moon．theMoon is closer to Earth and，therefore，its gravitational force is approximately 2．2 times greater．”判断可知，地球对太阳和月球的引力大小是由它们与地球之间的距离决定的。

25．B[解析]根据文章第五段的第二句“It takes approximatelv 24 hours and 50 minutes…
and two lunar tidal cycles occur during this time．”判断可知，一次月潮持续12小时25分。

26．D[解析]A项意为“接受彼此的缺点”；B项意为“评价彼此的不同处”；C项意为“应该包含在结婚誓言里”；D项意为“(尊重)和赞赏对一个令人满意的婚姻同等重要”。

根据文章大意判断可知，D项符合文意，故选D项。

27．C[解析]根据文章第六段第二句“Contempt is：the worst kind of emotion”可知．轻视伴侣对婚姻是最有害的。

28．C[解析]画线部分意为“同意(彼此的)不同点”，即他／她应面对他／她的伴侣并非一个完美的人的事实，故选C项。

29．D[解析】根据文章倒数第三段第一、二句“In good marriage…self-esteem．They may experience humorous incomprehension of one another’S preferences…”可知，文章建议如果你尊重你的伴侣，你可以用幽默的方式化解对伴侣的爱好的不理解。

30．A[解析]根据文意，画线部分在原句中意为“(用充满敌意的语气说话，任何‘好的事情’都会被)毁灭、误解”，即你说的话和你想表达的本意相反。

故选A项。

二、简答题
31．[参考答案]这句话所要表达的意图是：我的朋友英语讲得非常好。

该语误可能存在的两个问题：一是认为副词修饰动词时，应紧跟动词；二是受到汉语思维的影响，认为修饰语应放在中心语的前面。

正确的表达方式：My Mend speaks English very well．
My friend’S oral English is good．
三、教学情境分析题
32．[参考答案](1)教学目标：
知识与技能：
掌握同音词的正确发音：ship，sheep slip，sleep live，leave
掌握现在进行时的结构：be动词+υ…ing
情感与态度：
能够辨别目标单词的正确发音。

根据语义能够正确区分英语中的同音词。

(2)设计思路：
该教师设计的语音教学练习重点放在了听力理解和语法规则上，采用听录音的方式，应该教会学生正确掌握目标单词的发音；采用现在完成时的例句形式，应该教会学生用现在进行时表达生活中的场景和情感。

该教师考虑到了英语语音中同音的这一现象，并通过例句进行语音教学，可以进一步提高学生对英语的学习热情，增强英语学习的兴趣。

例句引用的都是现在进行时的句子，能够强化和巩固学生已学过的时态知识，但是这种形式比较单一，教师可以组织学生讨论已学过的同音词，另外还可以考虑从多个角度设计练习。

四、教学设计题

In l958．Australian scientist David Warren developed a flight-memory recorder that would trackbasic information like ahitude and direction．That was the first mode for a black box，which becamea requirement on all U．S．commercial flights by l960．Early models often failed to withstand cra’shes．however，so in l 965 the device was completely redesigned and moved to the rear of theplane—tlle area least subject to impact--from its original position in the landing wells(起落架舱)．The same year，the Federal Aviation Authority required that the boxes，which were never actually black，be painted orange or yellow to aid visibility．Modem airplanes have two black boxes：a voice recol-der，which tracks pilots’conversations，and a flight．data recorder，which monitors fuel levels，engine noises and other operating functions thathelD investigatorS reconstruct the aircraft’s final moments．Placed in an insulated(隔绝的)case andsurrunded by a quarte卜inch．thick panels of stainless steel，the boxes can withstand massive force and temperatures up to 2．000 T．When submerged，they’re also able to emit signals from depths of 20．000 ft．Experts believe the boxes from Air France Flight 447，which crashed near Brazil on June 1．2009,are in water nearly that deep，but statistics say they’re still likely to turn up．In the approxi- matelv 20 deep．sea crashes over the past 30 years，only one plane’s black boxes were never recovered．21．What does the author say about the black box?
A．It ensures the normal functioning of an airplane．
B．The idea for its design comes from a comic book．
C．Its ability to ward off disasters is incredible．
D．It is an indispensable device on an airplane．
22．What information could be found from the black box on the Yemeni airliner? A．Data for analyzing the cause of the crash．
B．The total number of passengers on board．
C．The scene of the crash and extent of the damage．
D．Homing signals sent by the pilot before the crash．
23．Why was the black box redesigned in l 965 ?
A．Because new materials became available by that time．
B．Because too much space was needed for its installation．
C．Because the early models often got damaged in the crash．
D．Because the early models didn’t provide the needed data．
24．Why did the FederM Aviation Authority require the black boxes be painted orange or yellow?
A．To distinguish them from the co]our of the plane．
B．To caution people to handle them with care．
C．To make them easily identifiable．
D．To confoITll to international standards．
25．What do we know about the black boxes from Air France Flight 447 7 A．There is still a good chance of their being recovered．
B．There is an urgent need for them to be reeonstructed．
C．They have stopped sending homing signals．
D．They were destroyed somewhere near Brazil．

Passage Two
Crippling health care bills，long emergency-room waits and the inability to find a primary care physician just scratch the surface of the problems that patients face daily．
Primary care should be the backbone of any health care system．Countries with appropriate pri-mary care resources score highly when it comes to heahll outcomes and cost．The U．S．takes the opposite approach by emphasizing the specialist rather than the primary care physician．
A recent study analyzed the providers who treat Medicare beneficiaries(老年医保受惠人)．
The startling finding was that the average Medicare patient saw a total of seven doctors--two primary care physicians and five specialists--in a given year．Contrary to popular belief，the more physicians taking care of you don’t guarantee better care．Actually，increasing fragmentation of care results in a corresponding rise in cost and medical errors．
How did we let primary care slip 80 far?The key is how doctors are paid．Most physicians are paid whenever they perform a medical service．The mort-a physician does，regardless of quality or outcome。

the better he’s reimbursed(返还费用)．Moreover，the amount a physician receives leans heavily toward medical or surgical procedures．A specialist who performs a procedure in a 30-minute visit can be paid three times more than a primary care physician using that same 30 minutes to dis-cussa patient’s disease．Combine this fact with annual government threats to indiscriminately cut re-imbursements，physicians are faced with no choice but to increase quantity to boost income．
Primary care physicians who refuse to compromise quality are either driven out of business or to cash-only practices，further contributing to the decline of primary care．
Medical students are not blind to this scenari0．They see how heavily the reimbursement deck is stacked against primary care．The recent numbers show that since l997，newly graduated U．S．medical students who choose primary care as a career have declined by 50％．This trend results in emergency rooms being overwhelmed with patients without regular doctors．
How do we fix this problem?
It starts with reforming the physician reimbursement system．Remove the pressure for primary care physicians to squeeze in more patients per hour，and reward them for optimally(最佳地) managing their diseases and practicing evidence-based medicine．Make primary care more attractive to medical students by forgiving student loans for those who choose primary care as a career and rec.onciling the marked difference between specialist and primary care physician salaries．We’re at a point where primary care is needed more than ever．Within a few years，the first wave of the 76 million Baby Boomers will become eligible for Medicare．Patients older than 85，who need chronic care most．will rise by 50％this decade．
Who will be there to treat them?
26．The author's chief concern about the current U．S．health care system is__________．A．the inadequate training of physicians。
