A． Evan Dobelle B． Nalewanski C． Stanley D． Moreno 答案 A 解析 細(xì)節(jié)理解題。通讀文章內(nèi)容可知 Nalewanski、 Stanley、 Moreno 都參與了救人工作，而根據(jù)文章最后一段可知 Evan Dobelle 是 Westfield State 大學(xué)的校長(zhǎng)，文章并沒(méi)有提及他當(dāng)時(shí)有沒(méi)有在現(xiàn)場(chǎng)，故他有可能并沒(méi)有參與救人。 39． The students helped people out through all of the following ways EXCEPT________.

Rich Miller is an editor of the Data Center says that puting power needs another kind of power which also has to e from centers need energy not only to operate their servers but to cool and protect their systems. The Environmental Protection Agency says the United States has about ten thousand data also says that they use almost two percent of the country’ s electricity. The amount and cost of energy used by data centers is the subject of growing wind power or some other renewable(可再生的 )energy for data centers could help the answer is to make servers more energy efficient. Still another solution may e from lets one server work like server usually runs a single operating system， like Linux or lets both run at the same time.
