第一题:

第二题:

A few years ago,Paul Gerner began to gather a group of  architects in Las  Vegas to ask then what it would take to design a public school that  used 50 percent less energy,cost much less to build and obviously  improved student learning,“I think half of them fell of their  chairs,”Gerner says.

Gerner manages school facilities(设施)for Clark  County,Nevada,a  district roughly the size of Massachusetts.By 2018,143,000 additional  students will enter the already crowded public-education system.Gerner  needs 73 new schools to house them.Four architecture teams have nearly  finished desingning primary school prototypes(样品);they plan to construct  their schools starting in 2009.The district will then assess how well  the schools perform,and three winners will copy those designs in 50 to  70 new buildings.

Green schools are appearing all over,but in Clark  County,which  stands out for its vastness, such aggressive targets are difficult  because design requirements like more natural light for students go  against the realities of a desert climate.“One of the biggest chalenges  is getting the right site orientation(朝向),”Mark McGinty, a director at  SH Architecture, says. His firm recently completed a high school in Las  Vegas. “You have the same building, same set of windows,but if its  orientation is incorrect and it faces the sun, it will be really  expensive to cool.”

Surprisingly, the man responsible for one of the most  progressive  green-design competitions has doubts about ideas of eco-friendly  buildings. “I don’t believe in the new green religion,”Gerner says.  “Some of the building technologies that you get are impractical. I’m  interested in those that work.”But he wouldn’t mind if some green  features inspire students. He says he hopes to set up green energy  systems that allow them to learn about the process of harvesting wind  and solar power.“You never know what’s going to start the interest of  child to study math and science,”he says.

1.How did the architects react to Gerner’S design requirements?

A.They lost balance in excitement.

B.They showed strong disbelief.

C.They expressed little interest.

D.They burst into cheers.

2.Which order of steps is folowed in carrying out the project?

A.Assessment—Prototype—Design—Construction.

B.Assessment—Design—Prototype—Construction.

C.Design—As  sessment—Prototype—Construction.

D.Design—Prototype—Assessment—Construction.

3.What makes it difficult to build green schools in Clark County?

A.The large size. B.Limited facilities.

C.The desert climate. D.Poor natural resources.

4.What does Gerner think of the ideas of green schools?

A.They are questionable B.They are out of date

C.They are advanced D.They are practical.

【答案解析】

【答案】B.【解析】推理判断题。根据第1段I think half of them fell off their chairs可知建筑师们对Gerner的要 求感到不可思议,不可相信。应选择B。A“他们激动得失去了平衡”,C“他们几乎不感兴趣”,D“他们突然大哭”都不符合本意。

2.【答案】D.【解析】文章结构理解。根据第2段的描述,工程的实施应按照“设计—提供样品—评估—建设”的程序。其它程序都不符合标准的建筑要求。

3.【答案】C.【解析】细节理解题。根据第3 段…such aggressive targets are difficult because design requirements like more natural light for students go against the realities of a desert climate 可知建筑绿色校园的难题是沙漠气候。而并非巨大的面积、有限的设施或贫瘠的自然资源。

4.【答案】A.【解析】细节推理题。根据最后1段 “I don’t believe in the new green religion,”“Some of the building technologies that you get are impractical…” 可知Gerner对上面提到的计划感到怀疑,应选择A。

第三题:

鹦鹉羽毛的黄色与蓝色是一对相对性状,若用H表示控制显性基因性状的基因,h表示控制隐性性状的基因,请据表回答下列问题:

亲代后代

黄色×黄色黄色、蓝色

(1)亲代鹦鹉的羽毛都是黄色,而后代鹦鹉的羽毛出现了蓝色,这种现象叫做。

(2)根据表中所示的遗传结果,从理论上可推断出鹦鹉羽毛的相对性状中色是隐性性状。

(3)试写出表中亲代鹦鹉最可能的基因组成有,后代中黄色鹦鹉的基因组成有

【参考答案】(1)变异 (2)蓝色 (3)Hh×Hh HH或Hh

第四题:

光导纤维的结构如图所示,其内芯和外套材料不同,光在内芯中传播。以下关于光导纤维的说法正确的是

A、内芯的折射率比外套大,光传播时在内芯与外套的界面发生全反射

B、内芯的折射率比外套小,光传播时在内芯与外套的界面发生全反射

C、内芯的折射率比外套小,光传播时在内芯与外套的界面发生折射

D、内芯的折射率比外套相同,外套的材料有韧性,可以起保护作用

【参考答案】 A
