【分析】
这道题是基础短语汉译英题型,解题时要优先选用英语中地道的惯用固定搭配,避免逐字直译产生中式英语:首先回忆对应含义的课本核心短语,注意区分动词搭配、介词短语作后置定语、泛指特指的冠词使用规则,逐个匹配含义,核对表达的准确性,确保所有短语符合日常英语的通用表达习惯,和课标要求的标准译法保持一致。
【解析】
1. 表达“忙个不停”的地道固定习语是on the go,是英语中描述人一直忙碌、没有空闲的常用表达。
2. “帮助那些需要帮助的人”中,“帮助”对应help,“那些人”用those指代,“有需要的”用介词短语in need作后置定语修饰those,组合得到help those in need。
3. 表示“在…的帮助下”的固定结构是with the help of...,“线索”用复数clues,因此得到with the help of the clues。
4. 表达“坚持(目标、原则)”的常用短语是stick to,后接名词the goal,得到stick to the goal。
5. “一次药检”即一次医学检查,用不定冠词a表泛指,得到a medical examination。
6. 表达“用于…的(药物)”常用介词for引出用途,因此“治喉咙的药”译为medicine for the throat。
7. “创造”对应动词create,“一个更好的未来”是a better future,组合得到create a better future。
8. 表示“提供帮助/援助”的常用搭配是provide aid,符合短语要求。
9. “捐赠”对应donate,“零花钱”是固定常用表达pocket money,组合得到donate pocket money。
10. “当代年轻人”的地道常用表达是the youth of today,符合通用译法。
【答案】
1. on the go 2. help those in need 3. with the help of the clues 4. stick to the goal 5. a medical examination
6. medicine for the throat 7. create a better future
8. provide aid 9. donate pocket money 10. the youth of today
【知识点】
固定短语搭配;英语惯用表达;介词用法
【点评】
本题全部考察中小学阶段英语学科的高频核心短语,没有偏难怪的内容,重点检验学生平时对课本固定搭配的积累程度,提醒学生记忆短语时不要死抠逐字翻译,要多积累地道的惯用表达,规避中式英语的错误。

这是一道结合汉语提示的单词拼写填空题,解题思路如下:第一步先通读完整句子,理清句子的语法结构,判断空格处所需要的词性;第二步结合给出的汉语提示,匹配对应的英文词汇;第三步结合语境确认词汇的形式(是否需要变复数、比较级最高级等),排除易混淆词汇,最终确定正确答案。比如看到be full of的介词短语后面要接名词,动词achieve后面也要接名词,定冠词the后面可以接名词或者形容词比较级,结合语境就能快速锁定所需词汇。
【解析】
1. 句子中固定搭配be full of意为“充满”,后面需要接名词作宾语,汉语提示“精力”对应的英文不可数名词是energy,直接填入原形即可。
2. 句中achieve是及物动词,意为“实现、取得”,后面需要接名词作宾语,汉语提示“成功”对应的抽象名词是success,符合语境要求。
3. 空格处修饰后面的名词sister,结合语境要表达家庭成员里排行更长的“年龄较长的”,elder专门用于表示亲属间年长的、排行靠前的,the elder sister即“大姐”,符合语义。
4. 空格前有形容词性物主代词my,后面需要接名词,汉语提示“口袋”对应的英文名词是pocket,此处指代我的口袋,用单数形式即可。
5. 空格前有定冠词the,后面接名词作worth的宾语,汉语提示“努力”对应的英文名词是effort,符合“值得这份努力”的语义。
【答案】
1. energy 2. success 3. elder 4. pocket 5. effort
【知识点】
单词拼写,词性判断,形容词词义辨析
【点评】
本题属于初中英语基础类单词考查题,所有考查词汇都是课标要求掌握的核心词汇,重点考察学生结合句子语法结构判断词性、匹配词义的能力,易错点在于第3空容易误写为older,要注意区分elder多用于亲属排行,older多用于年龄大小的通用比较。

No one is glad to hear that his body has to be cut open by a surgeon(外科
医生) and part of it is taken out. Today, however, we needn't worry about
feeling pain during the operation. The sick person falls into a kind of sleep,
and when he awakes, the operation is finished. But these happy conditions are
fairly new. It is not many years since a man who had to have an operation felt
all its pain.
Long ago, operations had usually to be done while the sick man could
feel everything. The sick man had to be held down on a table by force while
the doctors did their best for him. He could feel all the pain if his leg or arm
was being cut off, and his fearful cries filled the room and the hearts of those
who watched.
Soon after 1770, Joseph Priestley discovered a gas which is now called
"laughing gas". Laughing gas became known in America. Young men and
women went to parties to try it. Most of them spent their time laughing, but
one man at a party, Horace Wells, noticed that people didn't seem to feel pain
where they were using this gas. He decided to make an experiment on
himself. He asked a friend to help him.
Wells took some of the gas, and his friend pulled out one of Wells' teeth.
Wells felt no pain at all. As he didn't know enough about laughing gas, he
gave a man less gas than he should have. The man cried out with pain when
his tooth was being pulled out.
Wells tried again, but this time he gave too much of the gas, and the man
died. Wells never forgot this terrible event.

这是一篇事实细节类英语阅读理解题,解题核心思路是题干关键词定位法:逐题划出题干中的核心关键词,带着关键词回到原文对应段落查找匹配的原句,将原句表述和各个选项逐一比对,完全吻合的即为正确答案,所有题目的答案都可以在原文中直接找到依据,不需要额外复杂推理,注意不要主观脑补文中不存在的信息。
【解析】
1. 定位原文第一段最后一句:"It is not many years since a man who had to have an operation felt all its pain.",说明距离手术病人全程感知全部疼痛的年代过去的时间并不久,对应选项B not very long;选项A表述错误,C的few years含义是几乎没几年,和原文not many years表意不符,D的两千年在文中完全没有提及,因此选B。
2. 定位原文第二段第一句和第三句:"Long ago, operations had usually to be done while the sick man could feel everything."、"He could feel all the pain if his leg or arm was being cut off",明确说明很久以前病人做手术时可以感受到全部的疼痛,对应选项C;选项A是现代麻醉技术普及后的情况,B、D的内容在原文中完全没有提到,因此选C。
3. 定位原文第三段:"Horace Wells, noticed that people didn't seem to feel pain where they were using this gas.",明确说明使用笑气的人似乎不会感觉到疼痛,对应选项B;A、C、D的相关表述都没有在文中出现,因此选B。
4. 定位原文第四段第二、三句:"As he didn't know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out.",说明笑气剂量不足时,病人依然会感受到疼痛,对应选项C;选项A完全感受不到疼痛不符合原文,B文中没有提及,D是使用过量笑气的后果,因此选C。
