【当堂检测】阅读理解
①Lucky you--if you're looking for a four-leaf clover(四叶草),you might be able to find one in any clover patch(一块地)you come across! However, finding this sprout (嫩枝)will actually take some time.
②Clover plants grow in most temperate(温和的) areas around the world. They appear in places like fields and forests. These plants usually have three leaflets. Only about 1 in every 5,000 clover leaves has four leaflets.
③ ▲ A lot of it has to do with genes(基因).In humans, genes control eye colour, height, foot size, and much more. In clovers, genes decide things like the number of leaflets that a plant has. And a clover must have a special set of genes to grow four leaflets. The environment also affects how many leaflets a clover has. For example, four-leaf clovers grow better in warm temperatures than in cold ones. So, four-leaf clovers need just the right genes and environment in order to grow. This makes them difficult to see.
④ Looking through a clover land one by one to find a four-leaf clover might get a little tiring. Instead, when you come across some clovers, scan them with your eyes. Three-leaf clovers look like triangles, and four-leaf clovers look like squares. As you glance(一瞥)over the patch, look for square shapes in the sea of triangles.
⑤With time,patience(耐心)and a little good luck, you have a good chance of finding a four-leaf clover!
