ACT考试特色题型介绍：科学和文章改错

　　ACT考试和SAT考试一样都是美国大学的入学考试，ACT考试是American College Testing的简称，有ACT公司主办。ACT考试包括文章改错(English)、数学(Math)、阅读(Reading)、科学(Science)和写作(Writing)，其中写作为选作题。

　　在这五种题型中，我们今天重点介绍两种ACT考试特有的题型科学(Science)和文章改错(English)。

　　科学(Science)

　　这是ACT特有的题型，主要涉及科学领域，如：物理、化学、生物学、地质学、气象学等，考察学生对实验数据进行阅读、理解、分析和推理的能力。初次接触到科学推理，基本上所有学生会瞬间崩溃，但实际上科学是外强中干，貌似艰难无比，实则掌握了正确的方法和规律，就会柳暗花明。

　　ACT考试科学部分介绍-ACT Science Test

　　Length：35 Minutes

　　Question Types：

　　10 Social Studies Questions

　　10 Natural Sciences Questions

　　10 Prose Fiction Questions

　　10 Humanities Questions

　　On the ACT Science Test, you‘ll have 35 minutes to answer 40 questions—that’s about 50 seconds per question! The section contains seven passages, each followed by 5-7 questions.

　　You don‘t have to be a scientist or know the atomic number of Cadmium to succeed on the ACT Science Test. All that’s required is common sense. You‘ll be given passages containing various kinds of scientific information—drawn from the fields of biology, chemistry, physics, geology, astronomy, and meteorology—which you’ll have to understand and use as a basis for inferences.

　　ACT Science Question Format

　　Usually there are six passages that present scientific data, often based on specific experiments. Also, there‘s usually one passage in which two scientists state opposing views on the same issue. Each passage is followed by 5-7 questions. A warning: some passages will be very difficult to understand, but they’ll usually make up for that fact by having many easy questions attached to them. The test makers do show some mercy once in a while.

　　Top 8 Strategies for the ACT Science Test

　　Read through the instructions carefully, to orient yourself

　　Don‘t worry about details on your initial read-through

　　Always refer to the passage and the question-stem before selecting an answer

　　In order to read most graphs and tables, you have to do four things: determine what’s being represented, determine what the axes represent, take note of units of measurement, and look for trends in the data

　　When reading data, you should be on the lookout for the three characteristic patterns or trends: extremes (maximums and minimums), critical points (or points of change), and direct or inverse variation (or proportionality)

　　If time is a problem, focus on the questions that require analyzing data from just a single table or graph

　　Don‘t waste time trying to figure out which scientist is “right.” Just worry about understanding their different viewpoints

　　Don’t panic if you don‘t understand both scientists’ positions. Many questions will hinge on just one of the argument

　　文章改错(English)

　　这是ACT考试特有的题型，要求对文章中可能存在的错误或不甚完美之处选择最佳的改进方案。大部分题目类似SAT的篇章改善，但也有个别题目涉及文章衔接，如：提供4个句子，问在两段中插入哪一句能够使得上下两段衔接得更好。

　　以上就是关于ACT考试特色题型的介绍。包括了对科学部分和文章改错部分的介绍，非常详细。同学们在备考过程中，一定要对以上特色题型做到了熟于心，真正拿下ACT考试。
