Recently years,with the rapid development in our country,more and more people own their private cars.Some people think that private cars should be restricted,while others think that private cars should be encouraged.As far as I concern,I think owning a private car has both advantages and disadvantages.
On one hand,private cars do bring the owners convenience and comfortable.If you have a car,you don’t need to take the bus or subway to work.You can image how crowded and slow when you get on a bus, especially during the rush hours.With your own car,you just don’t need to worry about this problem.What’s more,you can go to any places at any moment with your private car.Traveling by car is very comfortable and flexible.You can stop as you pleased and don’t need to worry about others feeling.I guess this is the biggest advantages of private cars.
On the other hand,the disadvantages of private cars are obvious.The noises that produce by cars are unbearable,the exhaust gas that cars give off are bad for people’s health.With countless cars on the street, people find it becomes harder to find a parking spot.What’s worse,tens of thousands people are killed or injured in the traffic accidents.
To sum up,private cars provide us with convenience as well as harm. Whether or not afford a private car depends on personal details.
Nowadays,the controversial issue of cloning has been in the limelight and has aroused wide concern in the public.It’s quite understandable that the views of this issue vary from person to person.
Some people are in favour of cloning,who firmly believe that scientists can bring the extinct animals back to life by cloning.It’s indisputable that cloning is a great process to produce quantities of commercial plants as well as new species of plants.
However,the cloning of the sheep Dolly attracted public’s attention but arouse a storm of objections.For instance,if heaps and heaps of evil leaders like Hillary attempt to clone themselves,a disaster will break out in the world.In addition,the objectors insist that cloning has a huge impact on genetic diversity.
As for me,I suggest that cloning plays an important role on improving our quality of life.Needless to say,that cloning is an effective access to cure serious illnesses that at present have no cure.What’s more,not only can cloning assist us to acquire unknown knowledge about the creature,but it also is a wonderful breakthrough.Thought now there are lots of questions about cloning,by no means should we give in to the unsolved problems.
