　　D.Few microscopic species existed.

　　解析：

　　题干关键词：before the Cambrian period?

　　文中定位点：It was not until the Cambrian period, beginning about 600 million years ago, that a great proliferation ofmacroscopic species occurred on Earth and produced a fossil record that allowsus to track the rise and fall of biodiversity.

　　利用反义推理：It was not until the Cambrian period……allows us to track the riseand fall of biodiversity→Levels of biodiversity could not betracked.

　　所以选B

　　反义推理这个模式还可以被用在NOTEXCEPT题当中：

　　Five centuries later, about 7700B.C., a new village rose on the mound.At first the inhabitants still hunted gazelle intensively. Then, about 7000B.C., within the space of a few generations, they switched abruptly to herdingdomesticated goats and sheep and to growing einkorn, pulses, and other cerealgrasses. Abu Hureyra grew rapidly until it covered nearly 30 acres. It was aclose-knit community of rectangular, one-story mud-brick houses, joined bynarrow lanes and courtyards, finally abandoned about 5000 B.C.. Many complexfactors led to the adoption of the new economies, not only at Abu Hureyra, butat many other locations such as 'Ain Ghazal, also in Syria, where goat toebones showing the telltale marks of abrasion caused by foot tethering (binding)testify to early herding of domestic stock.

　　6.According to paragraph 5, after 7000 B.C. the settlement of AbuHureyra differed from earlier settlements at that location in all of thefollowing EXCEPT

　　A.the domestication of animals

　　B.the intensive hunting of gazelle

　　C.the size of the settlement

　　D.the design of the dwellings

　　解析：

　　题干关键词：after 7000 B.C

　　文中定位点：Then, about 7000 B.C……但我的思考是，之后的内容对应选项则会成为正确的内容，而题目需要我们找到错误的内容并且选出来，那么，7000BC之前的内容如果对应选项，就应该是错误的并且可以被选出来了，根据这个想法我们往前看

　　Five centuries later, about7700B.C., a new village rose on the mound. At first the inhabitants stillhunted gazelle intensively.

　　对应答案B

　　During wakefulness, breathing is controlled by two interacting systems.The first is an automatic, metabolic system whose control is centered in thebrain stem. It subconsciously adjusts breathing rate and depth in order toregulate the levels of carbon dioxide (CO2) and oxygen (O2), and the acid-baseratio in the blood. The second system is the voluntary, behavioral system. Itscontrol center is based in the forebrain, and it regulates breathing for use inspeech, singing, sighing, and so on. It is capable of ignoring or overridingthe automatic, metabolic system and produces an irregular pattern of breathing.

　　7..According to paragraph 2, all of the following are true of thevoluntary breathing system EXCEPT:

　　A.It has its control center in thebrain stem.

　　B.It controls breathing for a numberof activities during wakefulness.

　　C .It is able to bypass the automatic system.

　　D.It produces an irregular breathing pattern.

　　解析：

　　题干关键词：the voluntary breathing system

　　文中定位点：The second system is the voluntary,behavioral system.

　　反义推理：看到second则一定有first，思考是first的内容对应选项则一定不符合second的内容所以文中The first is an automatic, metabolic systemwhose control is centered in the brain stem.

　　因此正确答案为A

　　希望看了以上内容之后，大家可以对阅读题的套路更加熟悉，也能更好的去完成阅读题。
