托福综合写作机经试题

主题： Three methods of controlling the spread of kudzu

阅读

1. One way of getting rid of the invasive kudzu is by removing its root crown. The root crown is the part of the kudzu where its stem and roots meet. New kudzu vines grow from the root crown and not from the roots. Therefore, cutting just below the root crown and removing the crown from the soil will prevent new kudzu vines from growing and may help eradicate kudzu.

2. Another control technique involves transporting goats to areas overgrown with
kudzu and allowing the goats to graze (feed) on the kudzu to remove it. Goats are
relatively Small but eat a great deal, so a large herd of goats can be driven in trucks to areas of kudzu infestation, where the goats can graze until the kudzu has been cleared. Importantly, grazing by livestock weakens kudzu and prevents it from regrowing, so this control method has the potential to address the problem.

3. A third control method consists of using naturally occurring microorganisms, such as fungi, that feed on kudzu. Some scientists have recently conducted a series of experiments with fungi. When a kudzu plant was infected with fungi in the morning, signs of infection were already visible by the afternoon. Specifically, the plant's leaves had become weak and lifeless. The use of fungi may thus help eliminate kudzu.

1. Ok, the reading says that one way to stop kudzu from growing is to remove the root crown. Well, that's easier said than done. You see, although the root crown begins just two or three centimeters below the surface, it also grows deep into the soil. It's very hard to find the bottom of the crown dig below it and cut it from the system of roots beneath it. If any part of the crown remains in the soil after an attempted removal, kudzu will grow back quickly from this remaining part. And given the large size of the root crown and how deep in the soil it goes, the chances of some part of the crown remaining in the soil are high

2. Second, goats will fully remove kudzu only if you let them graze in the same area
continuously for a long period of time. Only continuous grazing weakens kudzu to the point of preventing its regrowth. So loading goats on trucks and moving them from place to place, as the reading suggests, will not work. If the goats stay in each area for just a short time, they will remove some K zoo, but as soon as they're moved to another area, the kudzu will grow back. Only long term continuous grazing works. But it's impossible to bring goats for long term grazing to all the areas infested by Kudzu.

托福学术讨论写作机经试题

Doctor Diaz: Let's continue talking about consumer behavior. We have been discussing different ways people go about choosing what products to buy, and there are many potential sources of information and advice for consumers. In your opinion, which is the better strategy for making purchasing decisions, relying on advice from friends and family, or depending on information from online sources? Why?
Kelly: Asking friends and family members for product recommendations might seem like an easier option, but it might take too much time to get all the information you need. An internet search would be much more efficient. There are many consumer magazines available online that compile lots of data to compare the advantages and disadvantages of one product versus another.
Andrew: The last time l bought a computer, l just watched a few videos online to make a decision, and now l regret that. My friends could have advised me better because they know my preferences and the kind of features that l am interested in. Consumers should get advice from the people around them to find the most suitable products.
