托福综合写作Topic 议题:option to solve Cheatgrass problem
Reading Listening
Thesis 总论点 The reading points out three methods to control Cheatgrass. Refute the three explanations mentioned in reading passage.
Sub-point 1 The first method is encouraging grazers such as cattle to eat Cheatgrass. Grazers prefer to eat native plants instead of Cheatgrass. This method will result in an unfortunate phenomenon that native plants might be damaged, especially those precious.
Sub-point2 The second method is using controlled fire to eliminate Cheatgrass. Fire cannot burn the whole Cheatgrass completely. Only the part above the soil surface will be destroyed by fire. Besides, the hardy seeds of Cheatgrass can germinate easily.
Sub-point 3 The third method is using fungi to restrict Cheatgrass. Cheatgrass and fungi have lived together for thousands of years in Europe and Asia. And some Cheatgrass has been resistant toward fungi. The fungi just work on injured Cheatgrass.
