Out of Control
As the man tried to swing the speedboat round，the steeringwheel came away in his hands.He waved desperately to his companion，who had been waterskiing for the last fifteen minutes.Both men had hardly had time to realize what was happening when they were thrown violently into the seaThe speedboat had struck a buoy，but it continued to move very quickly across the waterBoth men had just begun to swim towards the shore，when they noticed with dismay that the speedboat was moving in a circle.It now came straight towards them at tremendous speed.In less than a minute，it roared past them only a few feet away.After it had passed，they swam on as quickly as they could because they knew that the boat would soon return.They had just had enough time to swim out of danger when the boat again completed a circle.On this occasion，however，it had slowed down considerably.The petrol had nearly all been used upBefore long，the noise dropped completely and the boat began to drift gently across the water.
失去控制
当那个人试图使快艇转弯时，方向盘从手中滑脱，他拼命向他的同伴挥手，这个同伴在刚才十五分钟里一直在水上滑水橇。两个人都来不及弄清发生了什么事，就被猛烈地抛进了海里。快艇撞上了一只浮标，但它继续很快地穿过水面。两个人开始往岸上游，惊愕地发现快艇在转圈子，并以极快的速度向他们冲来。不到一分钟的工夫，汽艇在离他们仅几英尺的地方咆哮而过。汽艇过后，他们尽可能快地继续游着，因为他们知道汽艇很快还会转回来。他们刚刚游出险境，汽艇又转了一圈，不过这次速度大大放慢了。汽油已差不多用完了。有一会儿马达声完全消失，汽艇开始缓慢地漂在水面上了。
A Perfect Alibi
“At the time the murder was committed，I was travelling on the 8o’clock train to London.”said the man.
“Do you always catch such an early train？”asked the inspector.
“Of course I do.”answered the man.“I must be at work at 10o’clock.My employer will confirm that I was there on time.”
“Would a later train get you to work on time？”asked the inspector.
“I suppose it would，but I never catch a later train.”
“At what time did you arrive at the station？”
“At ten to eight.I bought a paper and waited for the train.”
“And you didn’t notice anything unusual？”
“Of course not.”
“I suggest，”said the inspector，“that you are not telling the truth.I suggest that you did not catch the 8o’clock train，but that you caught the 8：25which would still get you to work on time.You see，on the morning of the murder，the 8o’clock train did not run at all.It broke down at Fergreen station and was taken off the line.”
托辞完美
“在凶杀案发生的当时，我正坐着八点的火车去伦敦。”这个人说。
“你经常赶这班早车吗？”探长问。
“当然是的。”那个人回答说。“我必须在十点钟上班。我的老板可以证明我是准时到那儿的。”
“要是坐下一班火车能使你准时上班吗？”探长问。
“我想可以，但我从未坐过下一班的火车。”
“那你到火车站时几点？”
“八点差十分，我买了一张报在等车。”
“你没有发现什么异样的事吗？”
“当然没有。”
“我认为，”探长说，“你没有讲实话。你没有坐八点那班车，而是坐的八点二十五分那班车，这班车也能使你按时上班。因为，发生凶杀案的那天早上，八点这班车根本没开。火车在弗恩格林车站发生故障，那班车取消了。”
SlowDown—Radar
Whirrr！Whirrr！Whirrr！A police siren！And a flashing red light！The police car was after me！
I pulled my station wagon over to the side of the road.The police car stopped tooAnd I got my first ticket—for speeding.
“You were going 62miles an hour.”the policeman said.
“I didn’t think I was going that fast.”I answered.
“But you were.”the policeman said“I didn’t check you.Radar did.”
“Radar to check speeding？”I asked.“How does it work？”
“I’ll show you，if you have time.”the policeman said.
I followed the policeman back down the road to another car“The radar instruments are set up here.”he said“Officer Scott is the radar man.”officer scott pointed to an instrument.This instrument is aimed at
cars coming this way.It sends out radio waves.When the radio waves hit a car，they bounce back to the instrument.But they bounce back at a different wave length.The wave length is a shouter.The faster the car is moving，the shorter the wave length.”
Then Officer Scott showed me a second instrument.“This does the arithmetic.”he said.“It shows how fast a car is moving.It showed 62when the radar checked you.I called the police car parked up the roadI said that the station wagon was doing 62.”
I knew the next part of the storyI got a ticket.
The radar man pointed to still another instrumentHe pulled out a paper that was covered with ink lines.“We have a record of your speed.”he said“See this line？This is for your car.It hits 62.”
I got that ticket year agoI didn’t know then that radar was used to check on speeding.There were no signs to warn me.
But now I see signs to warn drivers.“SPEED CHECKED BY RADAR.”the sings say.The police want drivers to know that radar is used.When drivers know their speed is checked，they drive at a safe speed.That is the reason for the warning.And that is the reason for the radar check—to make our roads safer.
减速——前有雷达
呜—呜！呜—呜！呜—呜！一阵警车笛声！而且红光闪闪！警车在追我！
我把旅行车停到路边，警车也停下了。我收到今早第一张违章通知单——因为超速行车。
警察说：“你刚才的车速是每小时62英里。”
我答：“我不认为我行驶得那么快。”
“但你的确行驶得那么快，”警察说，“查你的车速的不是我，是雷达。”
“雷达查速度？”我问。“它怎么检查？”
警察说。“我会让你看的，如果你有时间的话。”
我跟随警察沿路往回走到另一辆汽车处。“雷达仪器就安装在这儿。”他说。“斯科特警官是雷达操纵员。”
斯科特警官指着一个仪器。“这台仪器对准这条路上来的车。它发出无线电波。无线电波碰到汽车上后，就反射到这台仪器上。但反射回来的无线电波的波长改变了。回波的波长比去波短。车跑得越快，回波的波长越短。”
接着。斯科特警官又让我看另一台仪器。“这是计算用的。”他说。“它显示汽车行驶得多快。刚才用雷达测验你的车速时，这显示的是62。我就呼叫停在马路前方的警车。我说，那辆旅行车的车速为62英里。”
我知道了故事的后一部分。我收到了一张违章通知单。
雷达操纵员指着又一台仪器。他抽出一张纸，上面涂满墨水线条。“我们有一张你的车速的记录，”他说，“看到这条线了吗？这是代表你的汽车的。它达到了62。”
我收到那张违章通知单是几年前的事了。那时，我还不知道警方用雷达来检测超速行车。当时还没有交通标志牌来提醒我。
但是，现在我看到提醒司机的标志牌了。标志上写着，“雷达测速区。”警方这样做，为的是要提醒司机，他们正在使用雷达。司机们知道他们的车速正受到检测时，他们就会以较安全的速度行驶。这就是告诫的理由，这也就是雷达测速的理由——使我们的道路更安全。
All Together Now！
Have you ever heard of homemade music？That’s right—homemade music.Music that is made at home can be lots of funAnd all of the family can take part in it
“Not my family.”you may be saying.Why not？You don’t have to have good voicesAnd you don’t need to buy a musical instrumentAll that a family needs is to want to make music.
A singing game my family likes is Grazy Voices.Each person sings a different song.But everybody sings at the same time！We do sound a little crazy.But the tunes all fit together.
The trick is to use the right songs.We have lots of fun with “The Sideways of New York”，“A Bicycle Built for Two”and “In the Good Old Summertime”.
Sometimes we get all mixed up Then we just hum the songs.Or we put our hands over our ears.（That way each singer hears only himself.）Then we try it againAnd crazy voices fill the air！
There are little children in our familyFor them we get a rhythm band togetherWe don’t have any fancy instruments.We use things like egg beaters，tissue paper and combs，jugs whistles，flying pansOur best song is “Yankee Doodle”.One person gets us started.He taps out the rhythm with his foot.Then we are off！
