[00:09.97]Exercise 1.2
[00:13.66]In many big cities in the world ,
[00:16.39]the over use of cars is thought to be
[00:19.18]one of the major causes of air pollution,
[00:22.03]What will cars be like in the future?
[00:25.38]Some experts² think that today's cars are
[00:27.45]in trouble because they use too much gas,
[00:31.63]They say the car of the future will be much，
[00:34.15]much smaller.
[00:36.15]The car of tomorrow will be made without a
[00:38.43]motor or air conditioning⁴.
[00:40.77]It'll have no radio and no lights,
[00:43.90]Tomorrow's car will be an open air car
[00:46.17]with no doors and windows,
[00:48.67]It won't need a pollution control system
[00:51.29]because it won't use gas .
[00:53.71]In fact,this new car will be pushed
[00:56.34]by the driver's feet,
[00:58.50]Very few people will be killed in accidents,
[01:01.69]because the top speed will be
[01:03.42]five miles per³ hour.
[01:05.66]However,we are also warned⁵ not to
[01:08.14]ask for pretty colors,
[01:10.31]because the cars will come in gray only.
[01:13.92]Other car experts do not hold the same idea.
[01:17.67]They are sure that the future will be happy.
[01:20.62]They think that all our problems will
[01:22.38]soon be solved by car companies
[01:24.53]with the production⁶ of the Supercar.
[01:27.48]Tomorrow's car will be bigger,faster,
[01:29.73]and more comfortable than before.
[01:32.08]The Supercar will have four rooms ,
[01:34.61]color Tv,running water,heat,air conditioning.
[01:38.98]and maybe a swimming pool.
[01:41.05]Large families will travel
[01:42.56]on long trips comfortably.
[01:44.90]If gas is in short supply⁷,
[01:47.51]the Supercar will run on water.
[01:55.69]Exercise 2.1
[01:59.46]Ask the Expert¹:
[02:01.42]The page where we try to answer
[02:03.28]all your problems,large and small.
[02:07.07]My question is about food,
[02:09.66]especially about fruit.
[02:11.50]Is it possible to freeze⁸ strawberries?
[02:15.48]Many fruit can be frozen⁹ very easily.
[02:19.49]As a rule,
[02:20.67]soft fruits like strawberries,etc.
[02:23.78]are difficult to freeze.
[02:26.65]I have just bought a shirt in a street market.
[02:30.11]The shirt is white
[02:31.54]and it has some dark blue letters,
[02:34.03]How should I wash it?
[02:36.20]You should be careful the first time
[02:38.50]you wash your shirt
[02:40.43]because the blue color might come out
[02:42.63]and mark the white part.
[02:44.89]A shirt like this should be washed
[02:46.98]in cold water,by hand.
[02:50.56]I have a new computer.Is it okay
[02:53.75]if I put it on the desk under the window?
[02:57.27]It depends.
[02:59.44]Does the window receive a lot of sunlight¹⁰?
