问题 单项选择题

某生物研究小组的同学要为环保部门提供当地的有关环境污染报告,他们应采取下列哪种方法来了解当地的环境质量状况?()

A.观察法

B.调查法

C.实验法

D.模拟法

答案

参考答案:B

解析:A项,观察法是在自然状态下,研究者按照一定的目的和计划,用自己的感官外加辅助工具,对客观事物进行系统的感知、考察和描述,以发现和验证科学结论,故A不符合题意。 B项,调查是科学研究的常用方法之一。调查时首先要明确调查目的和调查对象,制订合理的调查方案。调查过程中有时因为调查的范围很大,就要选取一部分调查对象作为样本。调查过程中要如实记录。对调查的结果要进行整理和分析,有时要用数学方法进行统计。某生物兴趣小组的同学要为环保部门提供当地有关环境污染的报告,他们应采取调查法来了解此处的环境情况,故B符合题意。 C项,实验法是利用特定的器具和材料,通过有目的、有步骤的实验操作和观察、记录、分析,发现或验证科学结论,故C不符合题意。 D项,在难以直接拿研究对象做实验时,有时用模型来做实验,或者模仿实验的某些条件进行实验,叫模拟法实验,故D不符合题意。

     NEW YORK- Microsoft is pulling out of the International Consumer Electronics Show(CES), the

largest trade show in the Americas. It's joining Apple in saying that it prefers to put on its own events

when the time is right to show off its products.

     Microsoft said the next show, to be held Jan.9, 2012 in Las Vegas, will be the last show at which it

has a booth or the CEO delivers the customary kick-off speech.

     Company founder Bill Gates delivered keynote speeches at the show for 11 straight years. Current

CEO Steve Ballmer has delivered the speech for the past three shows and will present his last next

month.

      The software company has been one of the biggest U.S. supporters of the annual event, which

gathered nearly 150,000 people this year. Originally focused on living-room electronics, the show has

become the big annual U.S. event for all consumer technology after the demise of big computer-focused

shows such as Comdex.

     Microsoft says it will continue to use CES as a place to connect to customers, but it won't have a

booth because its product milestones don't align with the show's January timing.

At the upcoming show, Ballmer is scheduled to speak about the Windows 8 operating system. But the

software isn't expected to be ready until late 2012, so computer makers won't have any real Windows 8

products at the show.

     "They're not cooked yet. So he's going to be stuck trying to present a bunch of stuff that will be

months away from being ready," said technology industry analyst Rob Enderle.

     Apple doesn't participate in trade shows at all after pulling out of the Macworld Conference & Expo

after 2009.

     The Consumer Electronics Association, which organizes CES, said it has tremendous demand for

invitations to hold keynote speeches, and it has already received feelers from companies that want to rent

for the 2013 show the space where Microsoft usually has its booth.
