第9篇是不是这个?? (OG11-purple,第一篇)

Coral reefs are one of the most fragile，biologically complex，and diverse marine ecosystems on Earth. This ecosystem is one of the fascinating paradoxes of the biosphere：how do clear, and thus nutrient-poor, waters support such prolific and productive communities? Part of the answer lies within the tissues of the corals themselves．Symbiotic cells of algae known as zooxanthellae carry out photosynthesis using the metabolic wastes of the corals，thereby producing food for themselves，for their coral hosts，and even for other members of the reef community．This symbiotic process allows organisms in the reef community to use sparse nutrient resources efficiently．

    Unfortunately for coral reefs，however, a variety of human activities are causing worldwide degradation of shallow marine habitats by adding nutrients to the water．Agriculture，slash-and-burn land clearing，sewage disposal，and manufacturing that creates waste by-prod all increase nutrient loads in these waters．Typical symptoms of reef decline are destabilized herbivore populations and an increasing abundance of algae and filter-feeding animals．Declines in reef communities are consistent with observations that nutrient input is increasing in direct proportion to growing human populations，thereby threatening reef communities sensitive to subtle changes in nutrient input to their waters

 

Questions 1-5 refer to the passage above

1.The passage is primarily concerned with

(A)   describing the effects of human activities on algae in coral reefs

(B)   explaining how human activities are posing a threat to coral reef communities

(C)   discussing the process by which coral reefs deteriorate in nutrient-poor waters

(D)   explaining how coral reefs produce food for themselves

(E)   describing the abundance of algae and filter-feeding animals in coral reef areas

2.The passage suggests which of the following about coral reef communities?

(A)　　Coral reef communities may actually be more likely to thrive in waters that are relatively low in nutrients．
            

(B)　　The nutrients on which coral reef communities thrive are only found in shallow waters．

(C)　　Human population growth has led to changing ocean temperatures，which threatens coral reef communities．

(D)　　The growth of coral reef communities tends to destabilize underwater herbivore populations.

(E)　　Coral reef communities are more complex an diverse than most ecosystems located on dry land.

 

3.The author refers to＂filter-feeding animals＂(1ines24-25)in order to

(A)  provide an example of a characteristic sign of reef deterioration

(B)  explain how reef communities acquire sustenance for survival

(C)  identify a factor that helps herbivore populations thrive

(D)  indicate a cause of decreasing nutrient input in waters that reefs inhabit

(E)  identify members of coral reef communities that rely on coral reefs for nutrients

4. According to the passage l which of the following is a factor that is threatening the survival of coral reef communities?

(A)  The waters they inhabit contain few nutrient resources．

(B)  A decline in nutrient input is disrupting their symbiotic relationship with zooxanthellae．

(C)  The degraded waters of their marine habitats have reduced their ability to carry out photosynthesis．

(D)  They are too biologically complex to survive in habitats with minimal nutrient input．

(E)  Waste by-products result in an increase in nutrient input to reef communities．

5. It can be inferred from the passage that the author describes coral reef communities as paradoxical most likely for which of the following reasons?

(A)  They are thriving even though human activities have depleted the nutrients in their environment．

(B)  They are able to survive in spite of an overabundance of algae inhabiting their waters．

(C)  They are able to survive in an environment with limited food resources．

(D)  Their metabolic wastes contribute to the degradation of the waters that they inhabit．

(E)  They are declining even when the water surrounding them remains clear．

第一篇：短阅读。黑人文化研究

 

第一段：随着各种文化的融合，现代的历史学家对于西部开发的历史有了新的认识（这里破折号提到新历史学家挑战的就是西部片里描写的欧洲移民在西部开发中占主导地位），他们认为美国黑人应该是起了重要作用。（此处有题）但是奇怪的是一个美国黑人历史学家M的观点，却被现代历史学家给忽视了。

 

第二段：讨论忽视的原因。主要提了两个：Equality and Frictional

1是这种M的研究中带有自由、平等的思想。人们也通常认为这正是美国精神的来源，但是现代历史学家不重视这种思想，然后又讲了一点原因。

2是M主要通过写fiction来描述历史，现代科学家认为这不是真实的。

【应该是】现代历史学家
