托福机经写作
Integrated Writing:
阅读文章：1. Rootworms can be killed by pesticides. Pesticides还对植物有好处?
2. Early planting can avoid rootworms. 等到虫子吃的时候，植物的根茎已经很成熟了，虫子就不喜欢吃了。
3. Alternating of growing can avoid rootworms. Corn and soy 可以轮流栽培。虫子只爱吃corn,不爱吃soy。如果corn和soy轮流栽培，虫子在栽培soy的那年就会饿死。
听力段子反对：1. Some of the rootworms have already developed a resistance.
2. Frost, snowstorm can cause the early planting corn to die. 死的总数相当于被虫子吃了的数量。
3. Some rootworms can lay their eggs for 2 years, and can hatch their eggs when core is being planted.那些虫子可以等到栽corn时再hatch.
Independent writing:
Agree or disagree, It's more important for government to spend money on modern houses than on building traditional or historical building or homes.
