18.I would like to talk to you about space vegetables,and to show you that space vegetables are healthy and good for you.
Space vegetables are grown from seeds(种子) that have been taken to and brought back from outer space.The seeds are affected by radiation and low gravity in outer space.When they are brought back to the Earth,these seeds produce vegetables that are bigger,healthier and more nutritious (有营养的)than normal vegetables.However,some people worry about eating space vegetables.They think that space vegetables might not be good for us and could give us cancer as a result of their exposure (暴露)to radiation in space.People should not be scared,as space vegetables are actually perfectly healthy.
Here are some facts that you should know about space vegetables:
Space vegetables are grown from seeds that are carefully selected.When seeds are brought back from space,people test the seeds to make sure that the vegetables they grow will be safe to eat.There are no traces of radiation after testing.
Space vegetables are better for you than normal vegetables.For example,space tomatoes stay fresh for twenty days,which is one week longer than normal tomatoes.Another popular space vegetable is the pepper(辣椒).Space peppers contain 20per cent more Vitamin C than normal peppers.
After genetically modified(改进的) foods come onto the market,people worry that they are eating unknown things.For example,if nut genes are put inside potatoes,people allergic(对…过敏) to nuts might get very sick from eating these potatoes because they do not know they are also eating nuts.Unlike genetically modified foods,space vegetables have not been genetically changed.This means that no new genes are put into the vegetables.Therefore,they won't damage your health.

15.Little Tommy lived in a village with his grandpa.Each morning Grandpa was up early sitting at the kitchen table reading his book.One day Tommy asked,"Grandpa!I try to read the book just like you but I don't understand it,and I forget what I do understand as soon as I close the book.What's the (46)A of reading then?"
Grandpa pointed to an old coal basket in the corner and replied,"Take this basket down to the river and bring me back a basket of water."Tommy did as he was told.Of course,he brought back an(47)Bbasket.
Grandpa laughed and said,"You'll have to move a little faster next time."
Tommy tried again.This time he ran faster (48)A the result was the same.
"Grandpa,it was (49)Dto carry water in a basket."
"Tommy,I don't think you are trying hard enough.Why do you (50)C so easily?"
With lots of questions in mind,Tommy decided to have a last try.This time he did it even (51)D,but no matter how hard he tried,it still made no (52)A.
"See,Grandpa,it's useless!"Tommy shouted when he got into the house,(53)B.
"So you think it's useless?"the old man said,"Look at the basket."
Tommy looked at the basket and for the first time (54)Cthat it was different.Instead of a dirty old coal basket,it was clean,inside and out.
"Tommy,that's what happens when you read books.You might not understand or(55)D everything,but when you read it,you will be changed,inside and out."
