下面为大家总结的是SAT改进句子题的注意事项，希望大家备考SAT语法的时候进行适当的参考和借鉴。
Here are some general hints for Improving Sentences，提示大家可以在解答SAT改进句子题的时候注意下面的几点：
Read the entire sentence carefully but quickly. Note the underlined portion because that is the portion that may have to be revised.
Remember that the portion with no underline stays the same.
Mark choice (A) if the underlined portion seems correct. Check the other choices quickly to make sure that (A) is really the best choice.
Think of how you would revise the underlined portion if it seems wrong. Look for your revision among the choices given.
Replace the underlined portion of the sentence with choices (B) through (E) if you don't find your revision. Concentrate on the choices that seem clear and exact when you read them.
Looking up from the base of the mountain, the trail seemed more treacherous than it really was.
Answer Choices
(A) Looking up
(B) While looking up
(C) By looking up
(D) Viewing
(E) Viewed
The correct answer is E
Explanation
When a modifying phrase begins a sentence, it must logically modify the sentence's subject; otherwise, it is a dangling modifier. In this example, every option except (E) is a dangling modifier.
In (A), the phrase "Looking up from the base of the mountain" does not logically modify the subject "the trail." A person might stand at the base of a mountain and look up at a trail, but it is illogical to suggest that a trail looks up from the base of a mountain.
(B), (C), and (D) are simply variations of the error found in (A). Each results in a sentence that illogically suggests that a trail was looking up from the base of a mountain.
(E) is correct. Although a trail cannot itself look up from the base of a mountain, a trail can be viewed by someone looking up from the base of a mountain, so the phrase "Viewed from the base of the mountain" logically modifies the subject "the trail."
以上就是关于SAT改进句子题的注意事项的总结，都是英文版的，但是非常容易理解。大家可以在备考自己的SAT考试的时候，通过对真题的练习，对不同的做题方法和答题注意事项进行更加深刻的体会的练习应用。
