<綜合測驗>[題組:第16-20題]Astronomers have discovered the darkest alien planet known to exist in the galaxy. The Jupiter-sized planet, known as TrES-2b, is located in another solar system some 750 million light years away from Earth. Reflecting less than one percent of the sunlight 16 on it, TrES-2b is less reflective than black acrylic paint, and is blacker than coal. The only light that comes from TrES-2b is a faint red glow, 17 the heated coils on an electric stove or a very dim light bulb. Researchers believe this results from its extremely hot atmosphere, which is as high as 1,800°F (980°C), 18 its closeness to its sun-its source of energy. So how does this planet manage to absorb about 99% of the light it receives from its sun? 19 researchers are not completely sure, they believe it could be because its atmosphere is composed of light-absorbing chemicals like vaporized sodium or even some elements whose existence is not yet known. Although they may never be able to 20 exactly how the planet remains so stealthily hidden, scientists are sure of one thing-there are many more even darker planets out there just waiting to be discovered! 16. (A) falls (B) falling (C) fallen (D) to fall
答案
答案：(B)。略解：句意為該行星反射不到百分之一的照射陽光。sunlight與fall為主動關係，用現在分詞作後置定語，(B) falling符合語法；(A) falls(謂語動詞)、(C) fallen(過去分詞，被動)、(D) to fall(不定詞，將來)均不符，故選(B)。 報錯 ChatGPTDeepSeek
