Will you throw them away like most girls or try to reuse them? The story of Carly and Charley may help you. Carly and Charley are the girls who often lose their socks. At first, they just matched different colors or styles like some other girls. But most of the time, these socks couldn39。t match their clothes. So they came up with an idea and started Odd Sox: they collected these socks and gave them away to homeless people. But the problem wasn39。t solved. They still had missing socks until they realized that they could make a business out of it. So they set up Single Sox: he girls sell socks in packs(包)of three so you can mix and match as you wish. Each pack is super colorful and super inspiring(激勵(lì)人心的)—Carly and Charley have written words on every sock to encourage girls to celebrate their differences.

They taste good and you don39。t have to wash them before eating them. However, British scientists say that the fruit may disappear by 2050. One reason for this is climate(氣候) change. Scientists at the University of Exeter collected data(數(shù)據(jù)) from 27 countries and regions that produce 86 percent of the world39。s bananas. They found that climate change has improved growing conditions in 21 of these countries. In the past 60 years, the average yield(平均產(chǎn)量) has reached tons of bananas per hectare(公頃). However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world39。s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out. Shouldn39。t bananas grow more easily if it39。s hotter outside? In fact, the perfect temperature range for growing bananas is between 24 and 32 C. If temperatures get too high, they will stop growing. Diseases are another danger to bananas. Unlike other crops, the bananas we grow e from shoot cuttings(莖段) rather than seeds. This means that all banana plants have the same genotype(基因型). In other words, if a disease is able to kill one plant, it could kill them all. One serious disease is called Panama. Caused by fungus(真菌) in the soil, it spreads easily. It has spread across South Asia, Africa, the Middle East, and Australia. If one banana plantation(種植園) suffers from the disease, it will take 30 years until it is able to grow bananas again. Scientists have yet to find a cure for this disease.(1)What does the underlined word this in Paragraph 2 refer to? A.People39。s love for bananas.B.The taste of bananas.C.The convenience of eating bananas.D.The future disappearance of bananas.(2)What might happen if temperatures keep going higher? A.More countries will start to grow bananas.B.Bananas will grow better in most countries.C.Bananas will not be able to grow any more.D.Bananas won39。t be as tasty as before.(3)What does Paragraph 5 tell us? A.What diseases bananas may suffer from.B.How bananas are grown.C.How diseases can easily
