高三下册英语语法知识点

(3) pleased “高兴的，感到满意的”含义与glad基本相同。作表语时，句子的主语只能是“人”，而不能是表示事物的词语。be pleased with 表示“对……表示满 意”之意。

1. 表示阅读性地“看书”(即读书)，一般要用动词 read。如：
Don’t read such books. 不要读那样的书。

但是，在许多情况下，“看书”只需用read 就够了(尤其是泛泛地表示“看书”时)，无需后接book作宾语。如：
In the evening I usually read. 晚上我常常看书。
This light is too poor to read by. 这光线太暗不能看书。
I read much less now than I did at school. 我现在看书远比我上学时少。
2. 若不是表示阅读性地“看书”，而只是大概地看一看，比如看看书的封面、定价、内容提要等，或者回答问题时看看书的某些章节或字句等，或者是考试时悼词楸镜龋此时都不宜用动词read, 可用look at, see 等。如：
Can I look at those books? 我可以看看那些书吗?
Jim demanded to see my books. 吉姆要求看看我的书。
Please answer my questions without looking at your books. 请不看书回答我的问题。
Students must not look at their books during examinations. 学生考试不准舞弊。
