لغز الشمس الشابة الخافتة

مفتاح الإجابات

1. Early in its history, the Sun shone considerably more dimly than it does today, which raises an awkward question.“Considerably more dimly” تستخدم ظرفًا في مقارنة. “Which” تشير إلى الواقعة كلها.
2. If sunlight was so weak, why did liquid water apparently flow across the surface of the young Earth?“Apparently” هنا تعني يبدو أن. “Liquid” تُنطق LIK-wid؛ وحرفا qu بصوت kw.
3. One proposal is that a thicker blanket of greenhouse gases once trapped enough heat to keep the oceans from freezing.“Blanket” تُستخدم مجازًا. “Keep from freezing” تعني تمنع التجمّد.
4. Another suggests that the planet reflected less light than it does now, simply because there were fewer clouds.“Than it does now” تستخدم “does” بدل “reflects”. “Fewer” تُستخدم مع “clouds” المعدودة.
5. Neither explanation is settled, and that is precisely what makes the puzzle so attractive to researchers.بعد “Neither” يأتي فعل مفرد. “Precisely what” جملة مشقوقة تبرز السبب.
