  托福综合写作范文Sample answer:

  The reading and listening discuss about options to solve Cheatgrass problem. The reading points out three methods to control Cheatgrass. Whereas, the professor totally refutes the three points presented in the passage.

  Firstly, the professor rebuts the reading’s first method of encouraging grazers such as cattle to eat Cheatgrass. The professor claims that 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.

  Secondly, the professor contradicts reading’s second method of using controlled fire to eliminate Cheatgrass. The professor mentions that fire cannot burn the whole Cheatgrass completely, but only the part above the soil surface. The hardy seeds of Cheatgrass can germinate easily.

  At last, the passage points out the third method of using fungi to restrict Cheatgrass. However, the professor explains that 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.
