答案解析
1.【答案】A
【解析】考查形容词副词的用法。句意：单纯只是观察绝不能称之为科学。选项中alone可作副词或形容词，只作表语，不能作定语;而lonely只能作形容词，在句中充当定语或表语。alone是客观状态，表一个人或事物在环境中处于孤立状态。而lonely是一个人的主观感受。alone用作副词修饰动词时，应该放在动词后面作状语;alone用作副词时，也可作定语，意为“只有，仅仅”，但必须置于它所修饰的名词或代词之后。该题中alone作副词，可以做后置定语，因此选择A。
2.【答案】B
【解析】考查上下文语境。上文提到科学家通常澄清一个问题之后，这个问题便会引导科学家们在观察中找到答案。因此本题代词it指代前文中提到的a problem，正确答案为B。
3.【答案】C
【解析】考查动词固定搭配。Be aware of是固定搭配，意为意识到、知道。
4.【答案】D
【解析】考查特殊疑问词的用法。句意：“那么问题就来了，究竟观察和问题，孰先孰后?”which表示哪一个，因此答案选择D。
5.【答案】B
【解析】考查名词词义辨析。句意：“之所以需要观察都是源于好奇。”只有B项表达需要之意。
6.【答案】A
【解析】考查动词词义辨析。根据句意不难推断出空白处应该填入的词意为“引发，提出”，即观察又会在科学家的脑海里提出特定的一些问题。A表示上升、增高、提出(问题);B表示出现;上升;起立;C表示引起;唤醒;鼓励;D表示上升;高地;增加;出现。因此，正确选项为A。
7.【答案】C
【解析】考查动词不定式的用法。动词不定式置句首表目的，意为“为了满足他的好奇心，他开始进行一些观察……”，故正确选项为C。
8.【答案】D
【解析】考查连词用法。根据句意应选择顺承连词，答案D为正确答案。
9.【答案】C
【解析】考查介词的用法。句意为“通过实验……”，因此答案选择C。
10.【答案】B
【解析】考查连词的用法。
11.【答案】A
【解析】考查名词词义辨析。前文提到hypothesis，那么有了假说之后，科学家就需要通过好的想象力来进行实验。
12.【答案】A
【解析】考查动词的固定搭配。fit 为及物动词。
13.【答案】C
【解析】考查形容词词义辨析。valid 有效信息。
14.【答案】B
【解析】考查上下文关联。根据后文“others are very……”可知前文应该是与之相对应的“some”。
15.【答案】D
【解析】考查上下文关联。和前文simple相对应，选complex。
16.【答案】C
【解析】考查介词的用法。此处表示科学家们会用数字表格来陈述他们的调查发现。
17.【答案】B
【解析】考查代词。these指代前文measurements。
18.【答案】B
【解析】考查动词辨析。prove证明，此处意为“根据调查结果报告，科学家们将会用更确切的描述和对比研究来证实他的假设。
19.【答案】C
【解析】考查非谓语动词。based 过去分词做后置定语，be based on表示基于逻辑的假设。
20.【答案】D
【解析】考查动词词组辨析。lay off停止，裁员，lead to 导致。
