Enable students to learn more about agriculture, countryside and farming. By talking they can exchange their experience with each other.

Sweat down the field soon.

Sample writing:
A fish farm is a pond or cage in the sea where farmers raise fish. In this case farmers can help fish grow faster to be big enough. This summer holiday I'm going to visit a fish farm near Yingshan lake.
A fish farmer has to be careful when he keeps fish in a pond .He must keep the water of the ponds from becoming too dirty. He also is to keep fish very close together.
What I am most interested in is to feed fish. I think fish must be fed regularly--twice or three times a day. I enjoy the scene in which fish jump up to take food. Besides feeding, the other task I have to do is to try to stop fish being affected by disease. I understand that fish disease are a serious problem. If that happened, all the fish in the pond would die. So I have to examine fish for disease. If so,I have to give some medicine to the fish.
I imagine I'll be busy on a fish farm and have a good time.

SUMMING UP
Write down what you have learned about working the land.
We have learned about agriculture and deeds of Dr Yuan Longping. We also know what organic farming is and grasp how to express our ideas and write a poster.
From this unit you have also learned:
Useful verbs: expand export circulate rid…of reduce struggle equip
Useful nouns: hunger bacteria fertilizer mineral supply level
Useful adjectives and adverbs: super sunburnt satisfied fertile organic
Other expressions: would rather lead a…life refer to year after year
New grammer item: the –ing form used as the subject and object
Step III Project
As for project on Page 54.teachers can ask the students to choose three kinds of crops and refer to some books to find out where they are grown. Students may be asked to make a booklet after class and display it on the classroom wall for the rest of the class to enjoy. The contents of the booklet include if they can be grown in different climate and countries and where they cannot be grown.
Here are some information for them to refer to::
Cucumbers are grown for eating fresh or preserving as pickles. They must be grown in warm temperatures and full sunlight, and will not stand frost. Cucumbers mature quickly and are best suited to large gardens but can be grown in small areas if caged or trellised.
Cucumbers do best in loose, sandy loam soil but can be grown in any well drained soil. Remove rocks, large sticks and trash before preparing the soil. Leave fine pieces of plant material such as dead grass and small weeds. They will help enrich the soil when turned under. Spade the soil to a depth of 8 to 12 inches. This is about the depth reached by most shovels or spading forks. Turn each shovel of soil completely over so all plant materials are covered with soil.
Tomatoes are warm season plants requiring at least six hours per Temperatures are very important. Most varieties of tomatoes will not set fruit unless the average nighttime temperature stays above 55degrees. If nighttime temperatures are expected to drop below 55 degrees, protect the plants using a polyethylene film.
One of the most common problems with tomatoes is called blossom end rot which appears as a gray or dark leathery scar or rot on the blossom end of the fruit. It can also be caused by a lack of calcium in the soil. Another common problem of tomatoes is blossom drop. This can occur if nighttime temperatures drop below 55 degrees and plants are not protected. Germination and tube growth are so slow that the blossoms drop off before they can be fertilized.
Peas are a frost-hardy, cool-season vegetable that can be grown throughout most of the United States, wherever a cool season of sufficient duration exists. For gardening purposes, peas may be classified as garden peas (English peas), snap peas and snow peas(sugar peas). Garden pea varieties have smooth or wrinkled seeds. The smooth-seeded varieties tend to have more starch than the wrinkled-seeded varieties. The wrinkled-seeded varieties are generally sweeter and usually preferred for home use. The smooth-seeded types are used more often to produce ripe seeds that are used like dry beans and to make split-pea soup. Snap peas have been developed from garden peas to have low-fiber pods that can be snapped and eaten along with the immature peas inside. Snow peas are meant to be harvested as flat, tender pods before the peas inside develop at all. The Southern pea (cowpea) is an entirely different warm-season vegetable that is planted and grown in the same manner as beans.
Step IV Checking yourself
This is a chance for students to collect knowledge they have learned in this unit. Teacher can give the students some time to discuss it and then finish the questions in the chart. Doing this task can improve students ability of teaching by oneself.
