解析

【分析】
1. 句子主语“微型摄像头”是动作“连接”的承受者,需用一般现在时被动语态,固定搭配“be connected to”表示“被连接到”,主语为单数,be动词用is;
2. 考查固定句型“It is believed that...”,意为“人们认为”,是表达普遍看法的常用被动结构;
3. 此处需名词短语作表语,“一项巨大的挑战”对应“a great challenge”;
4. 不定式可作目的状语,“解决不同的问题”用“to solve different problems”,故填to solve;
5. 主语“桥梁”是动作“修建”的承受者,用一般现在时被动语态,“be built”表示“被修建”,主语为复数,be动词用are。
【解析】
1. 主语A mini-camera是单数,被动语态结构为is + 过去分词,固定搭配be connected to,故填is connected to;
2. 固定句型It is believed that...是常用表达,意为“人们认为”,故填It is believed;
3. “一项巨大的挑战”译为a great challenge,作表语,故填a great challenge;
4. 不定式作目的状语,“解决”是solve,故填to solve;
5. 主语bridges是复数,被动语态结构为are + 过去分词,build的过去分词是built,故填are built。
【答案】
1. is connected to
2. It is believed
3. a great challenge
4. to solve
5. are built
【知识点】
被动语态、固定句型、非谓语动词

四、从方框中选择单词并用其正确形式完成短文
suppose frozen complete melt tunnel
press introduce find allow improve
Building a tunnel in high-altitude cold areas has long been a tough task. The biggest trouble comes from the
frozen
1
soil there—it stays as hard as stone in winter, but once summer arrives, it starts to
melt
2
rapidly. This sudden change often makes tunnel walls collapse, so people used to
suppose
3
such a project was nearly impossible.
Years ago, a team of engineers decided to solve this problem. They first
found
4
out that the key was keeping the soil frozen all year round. Then they came up with a creative plan: before starting construction, they would
introduce
5
a special cooling system. Workers
press
6
thin metal pipes into the soil along the tunnel path, and a low-temperature liquid flows through these pipes. This system keeps the soil frozen even in hot months, which
allows
7
the tunnel to be
completed
8
safely.
Today, this high-altitude
tunnel
9
is fully open. It connects remote mountain villages to cities, cutting travel time by half. More importantly, the technology has been used in other cold regions too—it not only
improves
10
local transportation but also shows how a smart idea can turn “no way” into “a way”.
