it.
— So you should believe in yourself.

A.produced
B.managed
C.realized
D.refused

【解析】先翻译对话:——我一开始害怕做演讲,但最后我成功做到了。——所以你应该相信自己。再分析选项:A. produced(生产;创作),不符合语境;B. managed(manage的过去式,manage it表示成功做成某事),符合句意;C. realized(意识到;实现),不符合;D. refused(拒绝),与语境相反。因此选B。

【解析】先梳理句子逻辑:前半句“移动支付让我们的生活便利”,后半句“我们不用带钱也能轻易买东西”,二者为让步关系。分析选项:A.so表结果,不符合;B.because表原因,不符合;C.so that表目的,不符合;D.even if表让步,意为“即使”,符合语境。因此选D。

)4. —
is the biggest blue whale?
— As I know, it weighs about 181,000 kilos.

A.How heavy
B.How long
C.How wide
D.How many

答案

4. A

解析

【分析】
本题考查特殊疑问句中疑问词的辨析。解题时需先分析答语的核心信息,再匹配对应的疑问词。答语提到蓝鲸“weighs about 181,000 kilos”,即重量,因此问句应是询问重量的疑问词组。逐一分析选项:A选项How heavy询问重量;B选项How long询问长度或时间;C选项How wide询问宽度;D选项How many询问可数名词的数量,由此可确定正确选项。
【解析】
根据答语“As I know, it weighs about 181,000 kilos”可知,答语回答的是蓝鲸的重量,因此问句需用询问重量的疑问词。A项How heavy意为“多重”,用于询问重量,符合语境;B项How long意为“多长;多久”,询问长度或时间;C项How wide意为“多宽”,询问宽度;D项How many意为“多少”,后接可数名词复数,询问数量。B、C、D均不符合答语的重量信息,故答案为A。
【答案】
A
【知识点】
疑问词辨析;特殊疑问句
【点评】
本题为基础的疑问词辨析题,结合答语的关键信息即可快速选出正确答案,考查学生对基础疑问词用法的掌握,难度较低。

解析

【分析】首先理解对话语境:一方说Tom昨天去北京度假了,另一方回应“我们今天早上还一起踢足球了”,说明另一方不相信Tom去了北京,因为今天还在一起活动。需要结合各选项含义判断符合语境的答语。
【解析】翻译对话:——Tom昨天去北京度假了。——______。我们今天早上还一起踢足球了。
逐一分析选项:
A. That's a good idea(那是个好主意):不符合语境,对方说的是Tom去度假的事,不是提建议;
B. I couldn't agree more(我完全同意):不符合,对方没有提出需要同意的观点;
C. You can't be serious(你不是认真的吧/你别开玩笑了):符合语境,因为今天还一起玩,所以不相信Tom去了北京;

五、任务型阅读。
You've probably heard of working dogs that help policemen or horses that help farmers.
Do you know that pigeons(鸽子) can be trained to help people too? Here are some examples.
The postman
People can train pigeons to carry messages. Usually, people tie a small can to a pigeon's leg with a note inside. Then the pigeon flies off with the note.
The lifeguard(救生员)
From high up in the sky, specially trained pigeons can find orange life jackets in the sea. Sometimes, it is difficult for humans to find people lost at sea, especially when the weather is bad. However, pigeons can fly quickly over a large area of water to look for people.
The spy(间谍)
Many years ago, people used pigeons to help their countries during wars. Spy pigeons had small cameras that were tied to their feet. As a pigeon flew over the enemy's (敌人的) land, the camera took photos of the land below. This would allow the soldiers to see where the enemies were and what they were doing.
