（10分）将一些能较好吸收和发射红外线的纳米级金属氧化物（如氧化铁、氧化铝、氧化锌等）通过特殊工艺织人纤维，然后用该种纤维制成的内衣，称之为红外保暖内衣。对于红外保暖内衣和普通保暖内衣在人体运动时，通气和散热的效果比较，某人设计如下实验：

①上午某时间穿红外保暖内衣，跳绳前测前胸体表温度，跳绳10分钟，再次测前胸体表温度。

②下午某时间同一人穿普通保暖内衣（假设普通保暖内衣和红外保暖内衣除材质不同外，其余都相同），在通风状况相同的同一房间里，重复上午相同的实验步骤。

③比较上、下午跳绳前后的体表温度变化量，得出两种保暖内衣通气散热效果强弱结论。

请回答下列问题：

（1）洗涤红外保暖内衣时，不宜选用的洗涤剂是                  （选填“弱酸性洗涤剂”、“弱碱性洗涤剂”、“中性洗涤剂”）

（2）若该人跳绳后腿部发酸，是因为肌肉细胞进行了                     

（3）有人认为根据该实验得出的结果不可靠，你认为该实验设计中变量控制不严密的地方是                  、                         （写两点）

（4）为了得出更可靠的结论，请写出你认为该实验最需改进的具体方面（写一点）

Passage Four

Global climate change, often seen as a process stretching over thousands of years, could in fact occur abruptly and unexpectedly-quickly pushing up temperatures by as much as 18 degrees Fahrenheit and wreaking havoc(大破坏，浩劫) on human society, scientists warned on Wednesday.
"Climate change is not always smooth. Sometimes it is abrupt," said Richard Alley, a climate expert at Pennsylvania State University and lead author of a new National Academy of Sciences report on the threat of rapid climatic shifts.
"If you have a very large, abrupt change, a lot of people and a lot of ecosystems are going to notice," he said．"The bigger and faster it is, the harder it will be to deal with."
The new National Academy of Sciences report, released this week, warns that gradual global warming coupled with other human impacts on the environment could "trip the switch" for sudden climate change.
At the American Geophysical Union meeting on Wednesday, Alley and other environmental scientists said the geological evidence indicated that such rapid climate shifts had occurred frequently in the past—moving temperatures drastically in the space of just a few decades.
"This can happen in less than a human generation, and then it will persist for thousands of years," said David Battisti, an atmospheric scientist at the University of Washington.
The most immediate dangers posed by abrupt climate change range are devastating droughts and floods which could seriously affect both water supply and agriculture across vast stretches of the planet.
Longer term impacts could include changes in the basic systems which determine regional global temperatures. Scientists believe that the Gulf Stream, a current (水流) of warm Atlantic water which now keeps much of Northern Europe temperate, could theoretically reverse direction if enough cool fresh water runs into the north Atlantic from melting ice, a change that would quickly impact European weather.

According to the passage, in the long run, abrupt climate change______.

A．could make the Gulf Stream warmer

B．could melt much ice on Earth

C．could submerge the whole European continent

D．could evaporate all fresh water on Earth
