Passage 1
The Pacific Ocean covers more of the earth's surface than all of Earth's land, and the Mariana Trench is the lowest point on Earth. However, it has only been little over a hundred years since humans first explored the depths of the Pacific.
In 1899, a Swedish scientist named Otto Sverdrup explored the Marianas with a rope and a lead weight. In 1951, researchers William Beebe and Otis Barton made the first descent in the Bathysphere, a small diving bell. They set the first depth record for aquatic exploration, reaching a depth of 923 meters.
Since then, scientists and explorers have been continuously discovering more about the Mariana Trench. In 1960, Jacques Piccard and Don Walsh made history by reaching the bottom of the trench, 10,928 meters below the ocean's surface. Only three people have ever visited this darkest and least understood corner of Earth.
In recent years, unmanned submersibles have been sent to the Mariana Trench to further explore its mysteries. In 2012, a robotic vehicle called the Nereus reached the trench's deepest point, known as Challenger Deep, at a depth of nearly 11,000 meters.

Passage 1
The world's population is projected to reach 9.7 billion by 2050, and feeding this growing population will be a challenge. One potential solution to this problem is insect farming.
Insects are a highly sustainable source of protein as they require less water, land, and feed compared to traditional livestock. They also emit fewer greenhouse gases and produce less waste. In addition, insects are rich in nutrients such as omega-3 fatty acids and vitamin B12.
Furthermore, insects can be farmed in urban areas, providing a local and efficient food source that reduces transportation and distribution costs. Insect farming can also create job opportunities and boost economic development.
However, there are cultural and psychological barriers to the acceptance of insects as a food source. Many people have a natural aversion to insects and may find it difficult to overcome cultural biases against consuming them. Education and awareness programs are needed to promote the benefits and safety of insect-based foods.
5. What is one advantage of insect farming mentioned in the passage?
答案：Insects require less water, land, and feed compared to traditional livestock.
6. What are some potential benefits of insect farming mentioned in the passage?
答案：Insects emit fewer greenhouse gases, produce less waste, and are rich in nutrients such as omega-3 fatty acids and vitamin B12.
Passage 2
