When many people think about planting a tree,...

When many people think about planting a tree, they do not realize that there are several things that they need to consider. You can’t simply just dig a single hole, throw the tree into that space, and expect it to grow without any disease. 1.

The first thing that you need to take into account is the time of year that you are looking to plant the tree in. Believe it or not, in order to plant a tree that will stay alive and be able to survive, you have to plant it at the time of year that is right for the tree. 2. The burning sun during these periods of time will cause a big amount of stress of the tree, which will then lead to its death. 3.

4. You should choose a suitable region and climate for the tree. If you decide to plant a tree that is not a native of a particular climate, you need to consider different factors about the tree such as the growth habits of the tree and how much tolerance the tree has to different weather conditions.

5. Sometimes in cases where people will be digging deep holes to plant a tree, they need to make sure that they are not digging around the phone lines that may be buried below the surface. Among other things, the hole determines if the tree can survive.

A. Normally you should never plant a tree in late spring or summer.

B. When digging a hole for a tree, you’d better dig as deep as possible.

C. You should then look at the place where you plan to plant the tree in.

D. The best time to consider planting your tree is around autumn or early spring.

E. The tree will not only be planted but will continue to grow well for years to come.

F. The next thing that you need to know is whether there are requirements where you’ll dig.

G. There are a few basic things that you need to do in order to make sure the tree grows healthily.

Today, many people use plants from other places to design their yards. Well, do they have any influence on animals living nearby? As we know, plants supply food for things like insects and plant-eating animals. In turn, birds and meat-eating animals feed on these insects and plant-eating animals. It is easy to see how important plants are.

Although foreign plants may look beautiful, they can cause problems when there are too many of them. I live in Virginia, USA, and sometimes see a plant—commonly known as Kudzu—that seems to cover everything in the area, even climbing over whole trees and houses.

Kudzu is an unbelievable plant since it grows very fast. It was first brought to the United States from south-east Asia around the 1870’s as a crop that farmers could grow. However, Kudzu quickly came to be considered harmful throughout the southern United States.

Since Kudzu grows fast in many different environments, it can completely cover areas of land quickly. The plant is also not eaten by any insects or birds in the United States so it can grow unchecked. Kudzu can cover trees, bushes, and even houses. It costs the United States 500 million dollars a year to just keep Kudzu from growing too fast. The plant is a perfect example of what scientists call an invasive (侵略性的) species, which grows more quickly than other native plants.

All foreign plants have the possibility to spread quickly. Not only are they costly, but planting them in gardens actually takes away food from insects. If everyone filled their garden with plants native to where they live, many lovely butterflies and other native creatures would be attracted to their backyards! So, take a look out of your window — how does your garden grow?

1.We can learn from the text that Kudzu in Virginia ________.

A. is very popular

B. is difficult to grow

C. can cause big trouble

D. can make air cleaner

2.Which of the following is TRUE of Kudzu?

A. It served as food at first in America.

B. It came to America in the early 19th century.

C. It grows fast in Asia, but slowly in America.

D. It is often eaten by insects or birds in America.

3.How does the author sound when telling of these foreign plants?

A. Sad.                B. Worried.                C. Proud.                D. Excited.

4.What does the author mainly discuss in the text?

A. Everyone should learn to love nature.

B. It is a hard job to grow plants in yards.

C. Gardening has become a serious hobby.

D. It is important to say no to foreign plants.

Coffee drink is widespread. When people argue about whether coffee is good for health, they’re usually thinking of the health of the coffee drinker. Is it good for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.

Traditionally, coffee bushes were planted under the shade of taller trees. However, more and more farmers in Latin America are deforesting the land to grow full sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t any trees. With increased production come increased profits.

Unfortunately, deforesting for coffee production immediately decreases the local wildlife habitat, because native birds nest and hide from predators（捕食者）in the tall trees and migrating birds rest there.

Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides（杀虫剂）are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, and then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.

Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade-grown" and "bird-friendly".

Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it’s worth it.

1.Which opinion does the author agree with?

A. People should buy full-sun coffee.

B. Shade-grown coffee should be supported.

C. Farmers should change the places to grow coffee.

D. Pesticides should be forbidden in coffee planting.

2.Compared with the traditional method, what advantage does the full-sun method have?

A. It can protect the ecosystem.

B. It can promote people's health.

C. It can provide mare nests for birds.

D. It can increase the production of coffee.

3.How do farmers get more land to grow full-sun coffee?

A. They cut down trees.

B. They move to other countries.

C. They turn grassland into farmland.

D. They buy more land from other farmers.

4.What can we learn from the passage?

A. It is quite worthwhile to buy shade-grown coffee at any cost.

B. Farmers all have realized the importance of protecting the environment now.

C. South American farmers are taking action to plant coffee in the traditional way.

D. The full-sun method does good to the health of human beings in the long run.

Are you nervous about climbing because you think it’s too dangerous? Do you feel you’re not fit enough to climb? Do you know how to start climbing?

Let’s consider the idea that climbing is dangerous. Being afraid is natural, but if you use suitable ropes and other climbing equipments you will feel completely safe. Climbers are usually very careful because they know what they are doing is dangerous. Accidents happen, but when they do, they tend to attract a lot of publicity. As a result, people think there are many more accidents than there are in reality.

You cannot expect to start climbing straight away. Climbing is a challenge and challenges take time. It is necessary first of all that you achieve a good level of fitness. Begin as soon as you become interested in climbing—go to the gym, go swimming, take up jogging and continue to do so throughout your training period.

Discover as much as you can about climbing. Visit the library and find books especially for beginners or buy climbing magazines and look for articles which describe your situation. Look up information on the Internet. Find out about equipment, methods and places to go.

Next, take a course on a climbing wall. There are plenty of climbing walls all over the country which have trained and qualified people as instructors. Call your local leisure centre to find out if there is one in your area. These training sessions are a quick way to get experience and you are likely to meet other beginners. After this, you can do an outside course or join a club where you can meet climbers of all abilities and eventually join in group-climbing events.

At first you may not understand the importance of a good training period, but after you have completed your first climb and you are standing safely at the top of a rock feeling thrilled, then you will know it was the right thing to do.

1.The article is written by ______.

A. a doctor　　　　　　　　 B. an experienced climber

C. a beginner　　　　 　　 D. a fitness instructor

2.The writer thinks a new climber should ______.

A. begin by becoming fit

B. be aware of the causes of the accidents

D. do enough sports to get interested in climbing

3.By climbing walls you can ______.
