文章大意:本文是一篇说明文。文章介绍了园艺中令人烦恼的杂草问题,提出可以用自然的方法替代除草剂来除草。

1 . Gardens are some of the most beautiful places on earth. The sad reality of gardening is that weeds compete with the plants you want and take away from their beauty.     1     Most people try to find a quick and easy solution to the problem of weeds by using chemical weed killers, known as herbicides. Sometimes, though, a solution can cause even bigger problems.

Actually using chemical herbicides can have quite a few unintended consequences.     2     They effectively kill weeds, but they can also kill other desirable plants and species. Not only that, but herbicides pose significant health risks to humans. And did you know that repeated use of herbicides can make weeds resistant to their effects?     3    

After weeds have already invaded your flower bed or garden, you obviously have to find a way to handle them. There are two basic methods of removing weeds: physical removal and mechanical removal. Physical removal — when using this method you are literally destroying the weeds by putting them out of the ground.     4     This method is generally very effective, but it takes effort. Mechanical removal — this method, which uses a weed eater or a lawnmower, mows weeds down to the ground. It doesn’t take out the roots, though, so the weeds will grow back.     5     With this method, it not only beatifies the garden but also saves you much effort.

By using some of these natural methods, you can keep your garden looking superb without using dangerous herbicides that could damage your health and the environment.

A.But herbicides use isn’t the only way to get rid of weeds.
B.Then, place garden plants close together to crowd out the weeds.
C.You can pull out the weeds by hand or take them out with a shovel.
D.As you might imagine, these chemicals poison the environment.
E.Here are some solutions to keeping weeds from invading your garden in the first place.
F.As for preventing weeds, covering the ground with landscapes fabrics may be a good way.
G.As a result, weed control seems to be a never-ending part of sustaining the beauty of a garden.
