解析

根据九年级英语常见短语及固定搭配进行翻译。
1. "碰巧"常用固定短语"by accident"或"by chance",此处按常见基础短语填写"by accident"。
2. "大学毕业以后","毕业"为"graduate","大学"是"college/university","以后"用"after",故为"after graduating from college/university"。
3. "现在,目前"对应的固定短语是"at present"。
4. "非常崇拜某人","崇拜"可用"look up to","非常"用"very much",即"look up to sb. very much"。
5. "死于饥饿","死于"为"die of"(死于内因),"饥饿"是"hunger",所以是"die of hunger"。
6. "比……有很多优势","优势"是"advantage","很多"用"many","比……"用"over",即"have many advantages over"。
7. "被引进","引进"为"introduce",被动语态"be introduced","被引进到……"加"to",此处基础表达为"be introduced"。
8. "对杂交水稻的研究","研究"是"research","杂交水稻"为"hybrid rice",用"on"表示"关于",即"research on hybrid rice"。

5.

答案

1. advantage
2. increased
3. agriculture
4. achievement

解析

1. 根据音标/əd'vɑ:ntɪdʒ/,可以确定该单词为advantage,表示“优势”。句意为“李现的帅气给了他相对于其他演员的优势”。
2. 根据句意“自从20世纪70年代以来,美国饮食中的盐分已经提高了百分之五十”,且结合汉语提示“提高”,可以确定该单词为increase的过去分词形式increased,因为句子是现在完成时。
3. 根据汉语提示“农业”,可以直接写出对应的英文单词agriculture,且此处的“农业”作为现代农业的整体概念,用单数形式。
4. 根据句意“当我们站在泰山顶上时,我们有一种成就感”,结合首字母a,可以推断出该单词为achievement,表示“成就”。
5. 根据对话内容“骡子是驴和马的后代”,可以推断出骡子是“杂交动物”,结合首字母h,可以确定该单词为hybrid。
二、用所给单词的适当形式填空

1. 定冠词the后接名词,discover的名词形式为discovery,此处用单数形式。
2. 修饰动词used用副词,wide的副词形式为widely。
3. 定冠词the后接名词,develop的名词形式为development,为不可数名词。
4. lots of后接可数名词复数,produce的名词形式为product,复数为products。
5. 修饰动词短语came down用副词,safe的副词形式为safely。

C
) 1.Doctors don't want more people to die ______ COVID-19, so they try their best to stop it.
A.for
B.with
C.of
D.at

答案

C

解析

本题考查介词固定搭配。“die of”表示“死于(疾病、衰老等内部原因)”,“die from”表示“死于(外部原因,如事故、外伤等)”,“COVID-19”是一种疾病,是内部原因,所以用“die of”;“die for”表示“为……而死”;“die with”表示“伴有……而死”;“die at”没有这种常见搭配表示“死于”的意思。所以本题应选C。
(
D
) 2.Vegetables have some advantages ______ meat for our health.
A.for
B.at
C.on
D.over

答案

D

解析

“have advantages over...”是固定搭配,意为“比……有优势”,符合句意“蔬菜比肉类对我们的健康更有一些优势”。其他选项无此搭配。
(
C
) 3.It is said that the number of forest parks in Guangdong ______ to more than 1,000 so far.
A.increase
B.increased
C.has increased
D.will increase

答案

C

解析

从题干“so far”可知,本句的时态应为现在完成时,表示从过去某一时间开始一直延续到现在并可能继续延续下去的动作,其结构是“have/has + 过去分词”。主语“the number of forest parks in Guangdong”是单数,所以助动词用“has”,“increase”的过去分词是“increased”,故此处应填“has increased”。
选项A“increase”是一般现在时;选项B“increased”是一般过去时;选项D“will increase”是一般将来时,均不符合题意。
(
C
) 4.— Hello, Peter. It is so noisy on the phone.
— Oh, Simon and I ______ lunch in a restaurant.

A.enjoy
B.enjoyed
C.are enjoying
D.were enjoying

答案

C

解析

根据题干中的“Hello, Peter. It is so noisy on the phone.”可知,这是现在正在发生的事情,说明Simon和Peter现在正在餐馆里吃午饭,所以应该用现在进行时。现在进行时的构成是“be + 动词的现在分词”,主语Simon and I是复数,所以be动词用are,enjoy的现在分词是enjoying。因此,正确答案是C选项,表示“我们正在餐馆里享用午饭”。
(
B
) 5.I heard a new song by Jay on the radio. I ______ high and low (到处) in the music store, but I can't find it up to now.
A.searched
B.have searched
C.am searching
D.will search

答案

B

解析

首先,根据题目中的“but I can't find it up to now”可知,寻找歌这个动作从过去某一时刻开始,持续到现在,并且还在进行或者刚刚结束,但结果仍未找到。这符合现在完成时的定义,即动作发生在过去但影响或结果延续到现在。接下来,我们逐一分析选项:
A. searched 是一般过去时,表示过去某个时间里发生的动作或状态,不符合题意;
B. have searched 是现在完成时,表示动作发生在过去但持续到现在,或对现在有影响,符合题意;
C. am searching 是现在进行时,表示现在进行的动作或存在的状态,不符合题意;
D. will search 是一般将来时,表示将来发生的动作,不符合题意。
因此,根据句子的时态和语境,应选择现在完成时,即选项B。
