题目内容
_______ hard they worked, they couldn’t satisfy the boss.
- A.No matter however
- B.How
- C.Whatever
- D.No matter how
解析:
词组no matter意为“不管;
无论”,与疑问词how连用,相当于however,引导让步状语从句。选项A中no matter不与however连用,因为however相当于no matter how, how不能引导让步状语从句,选项C中whatever引导让步状语从句时,在从句中能作主语、表语、宾语或定语,但不能作状语。
Did you know that a turtle(乌龟)can lay 12 eggs in one minute? A large sea turtle lays
around 150 eggs at a time. She lays all these eggs in just a few minutes.
Large sea turtles live in the warm seas of the world. Except for when they lay their eggs,
they spend their whole lives in the water. When it is time to lay their eggs, the females swim toland. They usually return to the place where they themselves were born. How they find theirway back there is unknown.When they reach shore, the big, heavy turtles crawl slowly up to the high water mark.Using their flippers, they pull themselves along the sand. They must struggle like mountainclimbers. When they finally reach dry sand, they rest before beginning the difficult task oflaying eggs.The turtles lay the eggs in deep holes and cover them with warm sand. The sand protectsthe eggs from harm. Then the females leave them. After a few weeks, if you happened to be walking along the beach, you might see the sand begin to shake. You may see tiny black ballscoming out of the sand. The tiny heads of baby turtles!
