3 . Born Hedwig Eva Maria Kiesler Nov. 9, 1914, the Austria native took an early interest in the performing arts, but seemed equally fascinated with science and engineering. In 1937, she signed a contract with Hollywood's Metro-Goldwyn-Mayer studio under the name Hedy Lamarr. Her first film was a great success and soon Lamarr was a household name.
During her Hollywood years, Lamarr was known for her knowledge on aviation (航空) design and theory. But it wasn't until 1942 that Lamarr's innovative thinking inspired a creative invention. In cooperation with composer George Antheil, Lamarr designed a frequency-hopping (跳频) system that minimized the jamming of radio signals.
During World War II, Hedy's mother was trapped in Vienna. It was hard for Hedy to help her mother to get to America because every American ship was getting blown up by the Nazis. So she worked on inventing a remote controlled torpedo (鱼雷) so advanced that it would be able to hunt down and blow up every Nazi submarine in the Atlantic, thus securing safe passage to the US. To make sure the Nazis couldn't detect the radio signal for her torpedo, she created a "secret communication system" that couldn't be detected.
The “ secret communication system" employed changing radio frequencies to prevent enemies from interpreting messages. Multiple radio frequencies were used to broadcast a radio signal, which changed frequencies in an apparently random manner. To anyone listening, it would just sound like noise. But the signal would be clear if both the sender and receiver hopped frequencies at the same time.
Although the technology was never used in wartime, it ended up playing a critical role in communication methods throughout the decades. Many believe that Lamarr's invention made technology like Wi-Fi, GPS and Bluetooth, as well as devices like cellphones, possible.

5 . Tropical rainforests are disappearing at an alarming rate, and according to a new report by Rainforest Foundation Norway, humans are to blame. The world's dependence on coal, farming. soy. palm oil and mining has resulted in two-thirds of Earth's tropical rainforests being completely destroyed, and the remaining ecosystems being put closer to a tipping point.
Tropical rainforests once covered 14.5 million square kilometers of Earth's surface, but now, just one-third of that remains intact. Of the original area tropical rainforests once occupied, 34% is completely gone and 30%is suffering from degradation. All that remains is roughly 9.5 million square kilometers, and45% of that is in a degraded state, the report says.
Researchers blame human consumption for the loss. While agriculture has always been a driving factor of rainforest loss, the report said that energy consumption, international trade and the production of soy and palm oil, logging and mining have been the largest threats over the past century. A significant number of U. S. commodities rely on resources from tropical rainforests. The country heavily relies on palm oil, rubber and cocoa, all of which come from forests around the world. Oftentimes, these resources are harvested from illegally deforested lands.
Tropical rainforests are home to more than half of the Earth's biodiversity and have more carbon in living organisms than any other ecosystem. Along with supporting significant animal life, tropical rainforests are also essential to slowing down global warming. “These highly specialized ecosystems are suffering from constant abuse, through our bottomless appetite for land and resources,” said Anders Krogh, who authored the report. “We expect that upcoming UN climate and biodiversity summits provide specific targets and measures to protect intact tropical rainforests.”
The rescarchers also believe that the loss of tropical rainforests puts the whole world at risk of future pandemics. “Massive deforestation is violating nature's natural virus protection systems.” Krogh said. “The aftermath of COVID-19 should bring rainforest protection to the top of the agenda of all policy makers and world leaders concerned about preventing the outbreak of new pandemics.”
1. What is the purpose of the numbers in paragraph 2?| A．To point out the threat to the current ecosystem. |
