Part 2 单元知识点考点汇总
1. 知识点:borrow vs lend
【用法辨析】
两者均表示 “借”,核心区别在于 “方向”:
borrow:“借入”,主语是 “得到物品的人”,搭配 borrow sth from sb(从某人处借某物);
lend:“借出”,主语是 “给出物品的人”,搭配 lend sth to sb 或 lend sb sth(把某物借给某人)。
【例句】
Jim, may I borrow your dictionary Mine is at home.(,“我” 借入字典,用 borrow)
Can you lend your storybook to me But you have to give it back this afternoon.(“你” 借出故事书,用 lend)
【即学即用】

2. My father often ______ (borrow/lend) his tools to his neighbors.(答案:lends)
2. 知识点:thousand 的用法
【用法】
前接具体数字(如 two/three)时,thousand 用原形,不加 s;
表示 “模糊数量”(成千上万)时,用 thousands of,thousand 加 s,后接名词复数。
【例句】

Thousands of students are watching the basketball match in the school gym.(模糊数量用 thousands of)

2. ______ (thousand) of people visit this park every weekend.(答案:Thousands)
3. 知识点:a perfect place to do sth
【用法】
“一个做某事的完美地方”,其中 to do sth 是不定式作后置定语,修饰名词 place,说明 “地方的用途”。类似结构:a good place to read(一个读书的好地方)、a nice room to live in(一个居住的漂亮房间)。
【例句】
Nanjing is a perfect place to taste some delicious food.(,不定式 to taste 说明南京是 “品尝美食” 的地方)

5. 知识点:反身代词(himself/herself/myself)
【用法】
反身代词表示 “某人自己”,当主语和宾语是同一人时使用,常搭配 by oneself(独自)、enjoy oneself(玩得开心)等短语。
【例句】
Go to the garden, and you can see ______ (himself).(,主语 you 和宾语 himself 指同一人,表 “你自己能看到他自己”)

1. 作后置定语:a place to do sth(、4)、a way to do sth;
