Native to Europe and Asia, cheatgrass is an invasive species of grass that is causing problems in North American fields. The plant quickly dominates fields that it has invaded and drives out other plants. This can cause, among other problems, severe damage to animal habitats and to scenic areas. Several solutions to the cheatgrass problem have been proposed by ecologists.

原产于欧洲和亚洲的cheatgrass 是一种入侵物种，给北美的土地带来了问题。这种植物很快占据了它入侵的土地，并将其他植物驱逐出去。除了其他问题外，这还会对动物栖息地和景区造成严重破坏。生态学家提出了几种解决旱雀草问题的方法。

One option is to encourage animals such as cattle to feed on cheatgrass. Cattle and other livestock are known as grazers because they graze, or eat. small portions of grass or other plants throughout the day. If grazers were released in fields where cheatgrass is prevalent, the cheatgrass would be reduced That would create room for native species to reestablish themselves and flourish. This plan is appealing because cheatgrass is most prevalent in areas of North America where cattle and other livestock are raised.

一种选择是鼓励像牛这样的动物吃旱雀草。牛和其他牲畜被称为食草动物，因为它们每天吃少量的草或其他植物。如果把食草动物放生到旱雀草茂盛的田地里，旱雀草就会减少。这将为本地物种的重建和繁荣创造空间。这个计划很有吸引力，因为在饲养牛和其他牲畜的北美地区，旱雀草最普遍。

Now listen to part of a lecture on the topic you just read about.

Professor:

The methods mentioned in the reading are not likely to work very well in controlling cheat grass.Here’s why.

阅读材料中提到的方法不太可能很好地控制旱雀草。原因如下。

First, cheat grass is not a plant that grazers prefer. This means that if grazers are released in a field that has a lot of cheat grass, but that also has other kinds of plants, the grazers will eat the other kinds of plants first. The grazers might eat some of the cheat grass, but only after the native grasses and plants, the grasses and plants that we are trying to protect, have been destroyed. So releasing grazing animals into fields with cheat grass with probably have the opposite effect of the one intended. There will be fewer native grasses, but plenty of cheat grass still around.

首先，旱雀草并不是食草动物喜欢的植物。这意味着，如果被放生在有很多旱雀草但也有其他植物种类的地方，食草动物会先吃后者。食草动物可能吃一些旱雀草，但只有在我们试图保护的原生牧草和植物被破坏之后。因此，将食草动物放生到有旱雀草的牧场可能会产生与预期相反的效果。所以周围将是更少的本地草与大量的旱雀草。

Second, fire will destroy cheat grass plants on the surface, but that doesn’t mean cheat grass won’t quickly come back. Cheat grass produces many many seeds. The seeds can germinate 。。。。此处省略一半原文！

Question: Summarize the points made in the lecture, being sure to explain how they cast doubt on the specific methods proposed in the reading passage.

TPO63综合写作范文：

The author in the reading holds that there exist several solutions to the cheatgrass problem, while the lecturer in the lecture expresses an opposite opinion.

To begin with, the author claims that it’s appealing to encourage animals such as cattle to feed on cheatgrass. However, the lecturer refutes that grazers don’t prefer cheatgrass, which indicates only after eating up native grasses and plants which are meant to be protected will grazers likely eat some of cheatgrasses. Consequently, releasing grazing animals in the field with cheatgrass will possibly backfire, giving rise to fewer native grasses but extensive cheatgrasses around.
