Passage 2
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to
eat. some research has shown that perhaps eighty percent of all human illness are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illness because of the food that is characteristic in these cultures.
That food related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in
our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful.
The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the
Food and Drug Administration （FDA） has tried repeatedly to control these procedures, the practices continue.
Why do farmers give drugs to their animals?

【教学设计】
Teaching aims:
Knowledge aim:
Students will master the meaning and usage of the structure “be doing” through reading the passage.
Ability aim:
Students will apply the “be doing” to communicate with each other in real situation.
Emotional aim:
Students will be more interest in learning English.
Key and difficult point:
Key Point: Students will master how to improve reading abilities through finding main idea and details.
Difficult Point: Students will apply the “be doing” to communicate with each other in real situation.
Teaching procedure:
Step 1: Warming-up
1. Greetings.
2. Play a riddle and students guess the animals, such as “long nose, big ears and strong body——elephant”, then lead to the topic of “let’s go to the zoo to see what animals are doing”.
Step 2: Pre-reading
1. According to the title, students have a prediction about what kinds of animals are mentioned in the passage.
Step 3: While-reading
1. Fast reading: students read the passage fast and figure out what kinds of animals are mentioned in the passage then make a list.
2. Careful reading: students read the passage carefully and answer the question: what are the animals doing? Then fill in the blanks.
1. How do you improve students’ interest in learning English?
2. What principle should you use in the post-reading step?答案：解析：1.
In the process of English teaching, teachers should enrich the teaching approaches, not only teach students through "listening, speaking, reading", but also integrate situational teaching, so that students can feel the diversity of teaching and learning.
Besides, teachers can make use of the form of cooperative study and organize various practice activities in the classroom to create an atmosphere of mutual assistance and cooperation, so that students have positive sense of learning.
2.
First, we should persist in the communicative principle. In the production step of reading
class, students should be organized in groups to cultivate their speaking ability and communicative ability. In this way, we can reach the New Curriculum Standard.
Then, we should insist on the truth principle. That means we should provide more real materials that are closet to students’ real life, such as situation creation like what I did in this class. In this way, students’ interest can be aroused and they can apply what they’ve learned in real communication. -

Investing in the stock market has always been more profitable man putting money into a traditional savings account. However, it is only in the last few years that private share ownership has become accepted as a reliable form of investment. There are many reasons why more and more people are buying shares. To begin with, the whole process is now far more flexible and user-friendly and public awareness of investment products and their tax implications is a lot higher. Even more importantly, this awareness means people now realize that in the medium to long-term shares are far more lucrative than deposit accounts. Today, people are also more likely to invest in a company for ethical reasons or as a show of support for that company.
When deciding to invest in shares, it is essential to think about your objectives. In order to avoid an expensive mistake, you need to consider your existing short-and long-term financial commitments and how quickly you expect to see a return on your investment. Most importantly, you need to decide the extent to which you are prepared to speculate and then select the investment products which best reflect your attitude towards the perils inherent in any stock market investment.
Recently, newspapers have been full of stories of investors realizing massive profits, usually in connection with the flood of Internet companies that have issued shares in the last 12 months. Such companies, however, are anything but a safe investment. Although people have been attracted by the phenomenal rate at which these companies are expanding, many investors have seen their shares fall well below the issue price within months of buying them.
Private investors unwilling to tolerate high levels of risk can reduce this uncertainly by buying shares in blue chip companies, which are established organizations such as banks or large international corporations. Although such an investment may minimize risk, it also limits the potential profits. Some investors try to remove the element of risk by closely monitoring stock market movements on a dally basis or by paying a regular sum into a managed fund over a long period of time. However, no matter how carefully people follow the markets or what expert advice they receive, statistics show that the safest option is to spread risk by investing in a wide range of different companies across different sectors.
As a first-time investor, it is Vital to seek professional advice. Consultants can provide information on how to invest in the most attractive companies in both the UK and overseas. They can explain how stocks, shares, unit trusts and bonds actually work, how much each type of investment costs and, most importantly, which products best match their clients’ requirements.
One reliable way of managing-investments is through a broker, who charges a brokerage fee in the form of a percentage of the money invested. An alternative method is to deal in shares on the Internet. This incurs none of the regular broker’s commission and investors can therefore easily afford to buy and sell shares more regularly. However, although some potential investors may find online trading exciting, they should be aware that direct trading is perhaps the least secure way of approaching the stock market, with few investors having the necessary skills and knowledge to make any profit whatsoever, never mind the fortunes popularized by the media.
