Important creativity (P4-5)
辽宁省沈阳二中 李珊珊
I. Lead-in:
Discussion
1. Who do you think is greater in terms of their contributions to the Western world: British physicist Isaac Newton or Greek philosopher Aristotle?

2. Which major will you pick when you enter college: A science major or a liberal arts major? Why?

II. Reading Comprehension
Read the article and answer the following questions.

1. Why are science majors called the “wiser” choice compared with liberal arts majors?
Science majors are the “wiser” choice because they’re considered to be useful, while studying liberal arts majors is believed to take you nowhere.

2. Why is the University of Wisconsin-Stevens Point considering dropping 13 liberal arts majors?
The reason is simple - liberal arts majors don’t have “clear career pathway”, according to a statement from the school.

3. What message does the BBC’s new documentary Civilizations convey?
Human civilization isn’t just about technological inventions, but also “those moments when human beings first began to create things that were there to be seen and to leave a mark of their existence for future humans to witness and admire.”

4. What’s the conclusion of the article?
Liberal arts majors are not less important than science majors. In fact, humans have combined both majors to make important examples of creativity.

III. Intensive Reading
It’s in Apple’s DNA that technology alone is not enough—it’s technology married with liberal arts, married with the humanities, that yields us the result that makes our heart sing.
本句中两次使用了it is…that…强调句型,分别强调“在苹果公司的DNA中”和“技术与人文学科的结合”;married with …作定语,修饰technology; 第三个that 引导定语从句,修饰先行词result.
释义:在苹果公司的DNA中,光有技术是远远不够的---只有让技术与人文学科相结合才能够创造出震撼心灵的产品。

IV. Grammar Focus:
强调句
 

 

 

 

 

 

 

强调句与主语从句的区别
强调句将句子中的it is / was …that同时省去,句子仍然成立;而主语从句将that与后面部分代替it,成立.如:
(1) It is Li Lei’s brother that you met in the street yesterday.
你昨天在街上所见到的就是李蕾的兄弟.
本句若将It is 及 that同时省去为:You met Li Lei’s brother in the street yesterday. 句子同样成立,因此前面的句子是强调句型.

(2) It is exciting that we have succeeded in sending up Shenzhou V. 我们成功地发射了神舟五号这件事情真令人兴奋.
本句若将It is 及 that同时省去为: Excitingly, we have succeeded in sending up Shenzhou V. 显然句子错误,因此,前面句子不是强调句型,而是主语从句.
强调句与定语从句的区别
It is in the house that he lives.    强调句
It’s the house where he lives.    定语从句
第一句,当我们把it is…that…去掉时,句子变为: In the house he lives. 句式结构完整,所以是强调句。
第二句很显然不能构成强调句式。先行词是the house, where是定语从句的引导词。因此第二句为定语从句。

Ⅴ. Exercises
1.-- Where did you meet him while in Beijing?   定语从句
  --It was in the hotel _____ I stayed.
A. that
B. which
C. when
D. where
2. –Where did you meet the famous actress?
  --It was in the supermarket ____we went shopping last Sunday.   定语从句
A. that
B. where
C. there
D. when
3. It was on October 15 ____ the Communist Party 17th Congress began.  强调句
A. that
B. when
C. where
D. which
4.It was a problem ____ we should support him.  主语从句
A. that
B. what
C. whether
D. if

Ⅵ. Assignment
Write a letter to the principle of the University of Wisconsin-Stevens Point. Try to suggest not dropping the 13 liberal arts majors and state your reasons.

 


Growing space food (P6)

江苏省江阴市第一中学  季春艳

Lead-in
Space exploration
It’s one small step for man; one giant leap for mankind.
First man to walk on the moon
Ø Name: Neil Armstrong
Ø Country: USA

Pre-reading
What do astronauts eat in space?
They usually eat dry food in airtight bags and cans.

While reading
Read the passage and answer the following questions.
1. Can space explorers eat foods such as fresh fruits and vegetables while exploring space? Why?
No, they can’t. Because there are strict weight limits on items taken into space so they typically rely on dry food in airtight bags and cans.

2. What difficulties have people attempting to grow food during space missions faced?
The absence of gravity, and a lack of soil, air and humidity.

3. What were the results of the experiments with human urine, according to New Scientist?
Human urine could supply three to four out of the six nutrients that plants need. Urine-fertilized plants also produce no harmful by-products, such as carbon dioxide or ammonia.

4. What is the advantage of a urine-fueled life support system, according to New Scientist?
By recycling liquid waste and producing food, an efficient cycle will be created. And most importantly, the duration of space missions will be greatly extended to “20 years of flight”, meaning we may be soon sending astronauts on missions to Mars, or even beyond.

Critical thinking
What is the point of space farming?
To begin with, plants planted in space will provide astronauts with more essential nutrients and fresh air, which is beneficial to their health. What’s more, the act of growing space food will bring mental comfort to the astronauts who miss life on Earth. Most importantly, the duration of space missions will be greatly extended, enabling astronauts to realize the dream of exploring Mars.

Post-reading
If you visited Mars as an astronaut, what would you grow? Give your reasons.
