《2025年金太阳导学案八年级英语上册人教版》

1. It's necessary _______ us to keep healthy. (填入一个合适的介词)

答案： for
解析：“It's + adj. + for sb. to do sth.”是固定句型，意为“对某人来说做某事是……的”，这里形容词“necessary”描述事物特征，所以用介词“for”。

2. It's silly _______ you to believe the man. (填入一个合适的介词)

答案： of
解析：“It's + adj. + of sb. to do sth.”中形容词描述人的性格品质，“silly”（愚蠢的）是描述人的，所以用介词“of”。

3. It's easy for him _______ (answer) these questions. (用括号内所给词的适当形式填空)

答案： to answer
解析：“It's + adj. + for sb. to do sth.”中真正的主语是动词不定式，所以此处用“to answer”。

一、根据句意及汉语提示完成句子
1. Because of the good news, she was _______ (太……而不能……) fall asleep last night.
2. Although they are from different countries, they _______ (有……共同点) a love for music.
3. The old photo on the wall always _______ (使……想起) my happy childhood.
4. —I'm not sure if I can achieve my dream in the end.
—If you _______ (坚持) your goal, you will surely make it.
5. Please _______ (写下) your name and phone number on this piece of paper.

答案： 1. too excited to
解析：“太……而不能……”用“too...to...”结构，“兴奋的”是“excited”。
2. have; in common
解析：“有……共同点”是“have...in common”，主语是“they”，用原形。
3. reminds; of
解析：“使……想起”是“remind...of...”，主语“photo”是第三人称单数，所以“remind”用“reminds”。
4. stick to
解析：“坚持”是“stick to”，if引导的条件状语从句，主句用一般将来时，从句用一般现在时，主语“you”用原形。
5. write down
解析：“写下”是“write down”，祈使句用动词原形。

二、用括号内所给词的适当形式填空
1. To prepare for the exam _______ (wise), making a study plan is necessary.
2. We can keep _______ (health) by eating well and exercising regularly.
3. He keeps his study _______ (organize) so that he can find things easily.
4. Winning the game made him feel _______ (confidence).
5. The story has a deep _______ (mean) and it makes us think about how to be kind to others.

答案： 1. wisely
解析：修饰动词“prepare”用副词，“wise”的副词是“wisely”。
2. healthy
解析：“keep + adj.”表示“保持某种状态”，“health”的形容词是“healthy”。
3. organized
解析：“keep sth. + adj.”，“organize”的形容词是“organized”（有条理的）。
4. confident
解析：“feel”是系动词，后接形容词，“confidence”的形容词是“confident”。
5. meaning
解析：“deep”修饰名词，“mean”的名词是“meaning”（意义）。
