使用关键术语
成绩单
这堂ACT视频课是关于在ACT科学考试中使用关键术语的。这些马古什的教学视频，你会听到我一遍又一遍的讲话
再说一遍关键术语。所以这是一个非常重要的视频，如果你不确定我的意思
但这也是一个重要的视频，因为如果你能训练你的大脑专注于寻找关键术语，而不是理解。
你将能够得到更多的问题，并增加问题的数量，你可以得到在允许的时间。 那么让我们开门见山，然后我将向你们展示我在一个例子中的意思。所以关键词是单词，短语，单位，和 numbers that you will be looking up on the figures and in the passage, or that you will be applying to answer the question.
So key terms are always the name and number of the figure experiment, etc, the question is referring to, any names of substances, objects, categories that appear. Definitely any numbers or percentages that appear in the question, or any trial or group numbers that appear in the question because those are what tell you where you're supposed to look.
And just a special hint. Anything that's capitalized, or a proper name, or has a numerical value. Is always a key term. The key term is always, what the question is actually asking you to find. Make sure you, specially highlight that. So for every single question, you want to underline the key terms in the question and circle what the question is asking you to find.
You can come up with your own system if you like, but this is something that works for a lot of students. And so if you're at a loss at what to do, go ahead and follow this rule of thumb. So, let's look at a couple practice ACT science questions. Now I want you to go ahead and pause the video for just a moment, and either on a piece of scrap paper or in your head, make a list of the key terms that you would underline and circle.
. Okay, so let's work through this together. 让我们从第一个开始。基于图1中的结果。 所以我们要强调这一点，因为这是告诉我们的数字或表格，我们应该看。
Which of the following could be the absorbance values. This sounds like a special term, I want to be looking for, absorbance values for samples containing four, we have a number. Four ppm, always underline the units as well. There could be. More than one and four, on the figure.
Of chromium and copper respectively. Okay, so, now that we've finished reading the questions, we know that absorbance values. That's what we're looking for. Specifically we're looking for the absorbance value at four ppm of chromium and copper.
So for our second example, based on the data in Figure 1 and Table 2, okay, so Figure 1 and Table 2 are key terms, that's where we're going to be looking. Can individuals of the Bombay blood type, all right, we've got something capitalized here. We have a proper noun, that's a key term. Receive blood from individuals with any ABO genotype.
ABO is a key term as well, too. As long as those individuals also have the hh genotype. That looks like a key term as well, too. So these are names of categories. 孟买，ABO，hh，这些肯定会出现在图1和表1的某个地方。
Now, you maybe be underlining a little bit differently, but hopefully, roughly, you got all of these same answers, because these are all very important key terms. So, once you've located your key terms in the question. You want to find and circle, underline, draw arrows to, etc. 文章、图表或图表中的关键术语。这里是图1，在我们刚刚注释的第一个问题中。
Our major key terms, other than the figure we're looking at, are absorbance values and ppm, as well as chromium and copper. 所以让我们继续圈出这些术语出现在图1中的位置。所以我们这里有铬和铜。 We have ppm down here, and specifically we are looking at four. And we have absorption which huh, close enough to absorption values to me.
我不知道我们会发现,graph. And now, we want to draw a line up where we see four, because we're looking for the absorbance values. So, we see absorption on our vertical access here. 在这里画一条线，确保我画对了。好吧，这个方块是铜的。
So, we can see at four it is about 13%. Now notice the line for chromium though with the triangles does not extend that far. So we need to extrapolate. We need to extend their line up to that point and take a guess at what its going to be up here.
So I'm gonna guess that that's about, my lines are not exact. 33, 34, don't forget the ACT is always gonna be looking for estimates so 他们永远不会把那么紧密的价值放在一起。如果我们看看我们的答案。 铜：13%，铬：34%。看来d是我们的正确答案。
So just to review, key terms are the names of figures, tables, experiments, scientists to which the question refers to. There are also any names of substances, objects, categories. Any numbers you see in the question. And you want to make sure that you underline or circle key terms on every single question.
这将有助于你在科学考试中集中精力阅读和积极搜索。它也能帮助你避免经常犯的粗心错误 occurrences when you're dealing with lots of teeny tiny charts and graphs and, and lots of data and labels. And don't forget that there may be key terms in the answer choices. So let's say you have a question that says, both Figure 1 and Table 1 show an increase in colon.
So there could be a lot of things that potentially increase. So you're gonna need to look at your answer choices in the case of a question like that, that has a really vague stem, to find out what you're supposed to be looking at. 比如说，在图1，冒号上有一个增加。寻找你的答案。
Maybe it says, chromium, maybe it says, copper there. And that's gonna tell you which lines you're supposed to be looking at. And also make sure you see our video on finding clues in the answer choices for more on how to strategically use the key terms you find in those choices.
