Question

【题目】 Most people may not think that there are any problems with watermelons， but some Japanese sellers do． There is often wasted space when they store watermelons， because round watermelons do not sit nicely on shelves． So some clever farmers have solved the watermelon problem． They make their watermelons grow in square glass boxes so the watermelons become square． The only problem now is the price． The square watermelons cost about 80 dollars each．

Many people know the saying "Roses are red， violets are blue， sugar is sweet and so are you．" Well， today the poem needs to change to "Roses are red， roses are blue"! Australian scientists have just recently discovered that when they put a chemical from a blue flower into a rose， they can create a nearly 100% blue rose． Some of science's inventions are beautiful， not just useful!

Since the mid﹣1990s， many Chinese farmers have had amazing rice harvests． For many years Chinese scientists have been working on developing new kinds of stronger rice and now they have produced a new kind， called super rice． Super rice not only can protect itself against insects and diseases， but it also produces more than any other kind of rice， Today farmers can grow almost one and a half times more rice than they could grow in the past．

Doctors might be able to use vegetables to fight cancer now． US scientists have discovered a way to put a chemical into tomato plants while they are growing． When cancer patients eat the tomatoes， the tomatoes will fight the cancer in their bodies． These cancer﹣fighting vegetables are not yet for sale， because scientists have not finished testing them． If study finds no problems with the tomatoes， then patients can begin to use this easy and delicious new treatment．
