新概念英语第二册Lesson 94 Future Champions课文详解+重点词汇+语法+语法填空 讲义

Lesson 94文本  Future champions Experiments have proved that children can be instructed in swimming at a very early age. At a special swimming pool in Los Angeles, children become expert at holding their breath under water even before they can walk. Babies of two months old do not appear to be reluctant to enter the water, It is not long before they are so accustomed to swimming that they can pick up weights from the floor of the pool. A game that is very popular with these young swimmers is the underwater tricycle race. Tricycles are lined up on the floor of the pool seven feet under water. The children compete against each other to reach the other end of the pool. Many pedal their tricycles, but most of them prefer to push or drag them. Some children can cover the whole length of the pool without coming up for breath even once. Whether they will ever become future Olympic champions, only time will tell. Meanwhile, they should encourage those among us who cannot swim five yards before they are gasping for air. 文本解析 一）词汇学习Word study 1. instruct vt．（1）指导，教，传授：Children can be instructed in swimming at a very early age.儿童在很小的时候就可以开始学习游泳。Dan instructs chemistry at a nearby college.丹在附近的一所学院教化学。 （2）指示，命令，吩咐：The doctor instructed Jimmy to stay in bed for a week.医生嘱咐吉米卧床一星期。I've been instructed to give you this parcel.我奉命将这个包裹交给您。 2. compete vi．（1）比赛，对抗（通常与 with或 against连用）：The children compete against each other to reach the other end of the pool.孩子们比赛看谁先到达游泳池的另一端。How many people will compete in the race?有多少人参加这个比赛？During the singing contest, Mary competed with Helen for the first prize.在歌咏比赛中，玛丽与海伦争夺一等奖。 （2）匹敌，比得上，媲美（通常与with连用，多用于否定句）：Hugh's house can't compete with yours.休的房子比不上你的。None of his later books can compete with his first one.他后来的书没有一本能比得上第一本。 二）课文详注 Further notes on the text 1. …children become expert at holding their breath under water even before they can walk．……孩子们甚至在还没有学会走路时就已经能熟练地在水下屏住呼吸了。（1）expert表示“熟练者”、“专家”，后面通常跟 at／in+ doing sth．结构（cf．第59课课文详注）：Rex so
