①It's hard to turn down a tasty banana. They taste good and you don't have to wash them before eating them. However, British scientists say that the fruit may disappear by 2050.
②One reason for this is climate (气候) change. Scientists at the University of Exeter collected data (数据) from 27 countries and regions that produce 86 percent of the world's bananas. They found that climate change has improved growing conditions in 21 of these countries. In the past 60 years, the average yield (平均产量) has reached 1. 37 tons of bananas per hectare (公顷) .
③However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world5s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out.
④Shouldn't bananas grow more easily if it*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.
⑤Diseases are another danger to bananas. Unlike other crops, the bananas we grow come from shoot cuttings (茎段) rather than seeds (系中子) . This means that all banana plants have the same genotype. In other words, if a disease is able to kill one plant, it could kill them all.
⑥One 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 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.

Dear Rita, How are you? Last time you asked me about the greatest invention in my eyes. I have also discussed it with my best friends, Anna, Sue and Kris. We have different ideas. Anna thinks it is the high﹣speed railway; Sue, the shared bike; Kris, the online shopping; and I prefer the Internet. The Internet is just like a net, and it connects us with the world. In the past, it was nearly impossible for people to communicate immediately with people in other countries. They had to spend a long time to reach their destinations (目的地), and not everyone could do that. But the Internet has made the impossible possible. Now we can communicate with foreigners online. The Internet also helps us know what is happening around the world, and has made our life and work easier. In recent years, shopping online is very popular. We can just stay at home and buy what we need online. We can also do online office work and distance education. Besides, we can watch movies, listen to music and even play games to relax ourselves on the Internet. So, I think that the Internet is one of the greatest inventions. It has changed our world! Although there are still many problems with the Internet, they will be solved in the near future. As a student we should make good use of the Internet! Yours, Martin |
