Students will be able to: know something about Nature & Nurture; grasp the main idea and structure of the text; master the key language points and grammatical structures in the text; conduct a series of reading, listening, speaking and writing activities centered upon the theme of the unit. Part One Teaching Objectives
Task 1: Nature? – Spotting out the truth! Task 2: Nurture? – Why was Einstein so clever? Task 3: Explanation – Like father, like son? Task 4: Nature or Nurture? – Talking about twins Part Two Preparation
Common sense and personal experience tend to suggest that nature and nurture are both important, each having a greater or lesser effect, depending both on the complexity of the gene and the conditions of the environment.
Nature: everything a person inherits genetically Nurture: home environment; the parental influences on the children, e.g. family influence peer influence educational experiences Nature & Nurture
Task 1Nature? Spotting out the truth! Directions: Decide which of the statements are scientifically correct. Your genes have a strong enough effect on your height for you to be able to predict what the adult height of your children should be if they are given a good diet. The need to wear glasses is not genetic. Most shortsightedness is caused by environmental influences such as using computers or reading a lots of small print. the percentage of body fat carried by a middle-aged woman is more determined by her genes than by diet or exercise. Your eating habits are governed by your genes. It would be as easy to change your dining habits as it would to change your breathing! Genes have great influence on our ability to withstand pain. This seems to be much less related to our experiences while we are growing up.
Task 2 Nurture? Why was Einstein so clever? Listen to a passage about Einstein and answer questions: 1. Was there something special about Einstein’s brain? Scientists have found that the part of his brain that has to do with visual imaging and mathematical thinking was enlarged. 2. Are there any other factors that helped nurture this genius? Einstein had a very supportive and encouraging environment in which to grow up. Task 2
Task 2Nurture! Genius without education is like silver in the mine. Benjamin Franklin 未受教育的天才，犹如矿中之银。 富兰克林 Genius only means hard-working all one's life . Mendeleyer 天才只意味着终身不懈的努力。 门捷列耶夫
What does it mean? Agree or disagree, why? (explanation must last at least 1 minute.) Task 3 Explanation Like father, like son.
Task 4 Nature or Nurture? Who are they?
Task 3 Nature or Nurture? Talking about Twins As children twins are usually raised together and share a very similar environment as they grow up. But one third of all twins born share much more than this – identical twins have exactly the same genes. Non-identical twins have genes which are as different as any normal brother or sister but their environment as they are growing up is very similar. Identical twins who have grown up apart were shown to have very similar dining habits despite their different upbringings. They like to eat at the same time of day and felt full after the same about of food. One of the most striking and magical features of identical twins is their appearance. Even close family often find it difficult to tell them apart. Task 3
Task 3 Nature or Nurture? Talking about Twins • Do you know any twins? What can you say about them? • Why are people curious about twins? • How do you think it feels to be twins? • what it must be like to grow up alongside a genetic copy of yourself ? Task 3

Assignment Directions: Write a composition on the topic: Which has a stronger influence, heredity or environment? Your composition should be no less than 120 words according to the outline given below in Chinese: 1) 父母遗传很重要； 2) 后天环境影响起关键作用； 3) 我们是先天遗传与后天环境的综合产物。
Which has a stronger influence, heredity or environment? Which is more important in shaping a person’s character, heredity or environment? First, let us examine the influence of heredity. A kind-hearted mother may expect a child who is also gentle and kind. An engineer father who used to get high marks in mathematics tests is very likely to have a son or daughter who is also good at math and plans to be an engineer, maybe because the child inherits the “math gene” from the father. Stubborn (顽固的) parents are likely to have children who are as hard to turn as a donkey (犟牛般的子女).
However, the environment also plays a key role in molding many of a child’s characteristics. Environment can change a person no matter what one inherits from parents. Exercise, sports and good food, for example, can make a person grow taller and stronger, which explains the reason why young Chinese are obviously bigger and taller than their grandparents. Intelligent professionals’ children are not necessarily intelligent, so intelligence is not inherited. On the other hand, the son of a thief is not necessarily a thief.
In conclusion, we are the product of nature and nurture. It is family, schools, and society that work together to shape who we are. Therefore, both heredity and environment have great influence on a person’s personality. Heredity creates a person, but environment can create an improved one.
