2026年课堂点睛八年级英语上册人教版第88页答案
考点1 易混辨析:can与be able to

根据汉语意思完成句子,每空一词。
1. 他现在能解决这个数学问题吗?
Can
he
solve this maths problem now?
2. 手术后,她将能够重新走路。
After the surgery, she will
be
able
to
walk again.

答案

1. Can he 2. be able to

解析

【分析】
先分析两个句子的语境:第1题询问现在的能力,对应can表现在能力的用法;第2题有将来时标志will,而can无将来时形式,需用be able to。再结合句子结构,第1题是疑问句,用Can开头加主语he;第2题will后接动词原形,be able to符合要求。
【解析】
1. 句子询问现在的能力,情态动词can可表现在的能力,疑问句结构为“Can + 主语 + 动词原形”,主语是he,故填Can he。
2. 句子有将来时助动词will,can没有将来时形式,需用be able to,will后接动词原形be,故填be able to。
【答案】
1. Can he 2. be able to
【知识点】
情态动词can用法;be able to用法;易混情态动词辨析
【点评】
本题考查can与be able to的易混辨析,结合时态、语义选择正确表达,是情态动词部分的基础考点。

考点2 易混辨析:health, healthy, healthily
health(名词) 健康状态(整体概念)
易混辨析
healthy(形容词) 描述人或事物的健康状态(a healthy child)
表示“有益健康的”(healthy food)
healthily(副词) 以健康的方式(修饰动词)
根据语境,用括号内单词的适当形式填空。
1. To stay in good
health
(healthy), you need to exercise regularly.
2. The child grew up
healthily
(healthy) because of his balanced diet.
3. We need to eat more vegetables and fruit to keep
healthy
(health).

答案

1. health 2. healthily 3. healthy

解析

【分析】首先明确三个词的词性与用法:health是名词,表“健康”;healthy是形容词,可修饰名词或作系动词后的表语;healthily是副词,用于修饰动词。再结合句子结构分析:第1题空格前是形容词good,需接名词;第2题空格处修饰动词短语,需用副词;第3题空格在系动词keep后,需用形容词作表语。
【解析】1. 空格前为形容词good,形容词修饰名词,括号内healthy的名词形式是health,固定搭配stay in good health意为“保持健康”,故填health。2. 空格处修饰动词短语grew up,需用副词,括号内healthy的副词形式是healthily,故填healthily。3. 系动词keep后需接形容词作表语,括号内healthy是形容词,符合语境,故填healthy。
【答案】1. health 2. healthily 3. healthy
【知识点】名词用法、形容词用法、副词用法、易混词辨析
【点评】本题考查易混词health、healthy、healthily的词性及语法功能,需结合句子结构和语境选择正确形式,属于基础语法考点。
