Try reading the following sentences as fast as you can. “ She sells seashells by the seashore. The shells she sells are surely seashells. So if she sells shells in the seashore, I’m sure she sells seashore shells.”
Not very easy, was it? What you’ve just read is called a tongue twister（绕口令）. It is an exercise made up of sounds that are hard to pronounce in order to help people pronounce words faster and more correctly. Try the next example.
“Peter Piper picked a peck of picked peppers, Did Peter Piper pick a peck of picked peppers? If Peter Piper picked a peck of picked peppers, where’s the peck of picked peppers Peter picked?”
Tongue twisters usually do not have much meaning. They are just designed to improve people’s ability（能力）to pronounce words. Although they may be very difficult, these exercises are very important to people who are trying to speak English correctly. This is because tongue twisters help people to tell the differences between similar sounds.
So if you wish to pronounce words more smoothly, you’d better try picking out some tongue twisters and practicing them.
