the wild was around 100 000.在二十世纪初期,野生老虎的数量大约是十万。the number of是固定短语,意为“的数量”,后接可数名词复数,谓语动词要用单数。如:The number of students in our school has grown from 1,000 to more than 1,500.Language points【注意】a number

balance.它可以帮助保持其他野生动物的数量平衡。balance 在句中用作名词,意为“平衡;均衡”,常用短语be out of balance,意为“不平衡”;keep in balance意为“保持平衡”;balance还作动词,表示“(使)平衡;(使)均衡”。如:You must learn to keep your balance in skating.在滑冰时你必须要学会保持平衡。3.In recent years,tigers have been in danger of disappearing.近年来,老虎已经面临消失的危险。danger意为“危险”,通常是不可数名词,表示做某事的危险或发生某情况的危险等,常用短语 be in danger(of),意为“在危险中”。如:Is there any danger of fire?有发生火灾的的危险吗?1._(长颈鹿)are the tallest animals on land.2.What beautiful _(婚礼)clothes they are!3.Uncle Yan visited many _(亚洲的)countries last year.4.He is interested in _(历史).history
