B
Airships were popular in the early 1900s. These aircraft can fly because they are filled with lighter-than-air gases. Some types have a rigid frame and all of them have a cabin(机舱)below the main body. Pilots and passengers are carried in this cabin.
Back in the 1900s, most airships were filled with hydrogen(氢气). The gas burns easily. In 1937, an airship called the Hindenburg caught fire during landing. Thirty-six people died as a result. The sad thing scared people away from airships. At that time, planes were improving quickly. Since then, people have been using planes for most air travel.
Now, an American company called Lighter Than Air (LTA) Research wants to change that. LTA Research has been working on its airship, Pathfinder 1, for about ten years.
The new airship, about 123 metres long, is the largest of its kind since the 1930s. It uses helium(氦气). This gas is also lighter than air but does not burn. The helium fills 13 separate parts of the airship. About 10,000 long carbon fibre tubes(碳纤维管) make up a strong frame to protect these parts. The airship is powered by 12 electric motors. The electricity comes from either batteries or generators(发电机). With these motors, the airship can take off and land without a runway.
Pathfinder 1 can carry about 4 tons of goods. It can fly at a speed of up to 120 kilometres per hour. In November 2023, the airship made its first test flights in California. LTA Research hopes to show that their airships can be used to move goods quickly without polluting the air.

答案：4. B 【点拨】根据第二段和第三段内容可知，that 应该指代的是出于安全考虑，人们宁愿乘飞机而不愿乘飞艇旅行。故选 B。
5. A 【点拨】根据第四段内容可知，作者通过列举数字描述新的飞艇。故选 A。
6. B 【点拨】根据后句“电力来自电池或发电机”可知，飞艇由 12 台电动机“驱动”。powered 驱动，与 driven 意义相近。故选 B。
7. B 【点拨】文章先介绍飞艇的历史与衰落，后重点讲述 LTA Research 公司研发的“探路者 1 号”飞艇，强调其安全、环保的特点，B 选项既点明核心对象，又概括其优势，最适合作为标题。故选 B。

### B
飞艇在20世纪初很受欢迎。这些飞行器能够飞行，是因为它们内部填充了比空气轻的气体。有些类型的飞艇有坚固的框架，并且所有飞艇在主体下方都有一个机舱。飞行员和乘客就在这个机舱里。
早在20世纪，大多数飞艇都填充氢气。这种气体很容易燃烧。1937年，一艘名为“兴登堡号”的飞艇在降落时起火。结果有36人丧生。这件悲惨的事让人们对飞艇望而却步。当时，飞机正在迅速改进。从那以后，人们在大多数航空旅行中都使用飞机。
现在，一家名为“轻于空气（LTA）研究”的美国公司想要改变这种情况。LTA研究公司已经致力于其飞艇“探路者1号”的研发约十年了。
这艘新飞艇长约123米，是自20世纪30年代以来同类飞艇中最大的。它使用氦气。这种气体也比空气轻，但不会燃烧。氦气填充了飞艇的13个独立部分。大约10000根长碳纤维管构成了一个坚固的框架，以保护这些部分。这艘飞艇由12个电动马达提供动力。电力来自电池或发电机。有了这些马达，飞艇无需跑道就能起飞和降落。
“探路者1号”可以运载约4吨货物。它的飞行速度最高可达每小时120公里。2023年11月，这艘飞艇在加利福尼亚州进行了首次试飞。LTA研究公司希望证明，他们的飞艇可以用来快速运输货物，而且不会污染空气。
