Result

 

 

 

Charles Darwin

 

 

The wild life of Galapagos, many varieties of garden roses

 

 

There were differences between the species of the different islands’yet all showed a clear relationship with those of America’ differences in habitat could lead to different species in birds as well as in plants.

 

 

Gregor Mendel

 

 

 

Flowers and peas

 

 

Many characteristics were passed on from one generation to the next, without influence by the environment. His research gave  birth to the science of genetics.

 

 

 

Gote Turesson

 

 

A wild plant found on the Swedish west coast

 

 

Found evidence for the existence of stable varieties within species in nature. He showed that differences between plants of one species occurred as a result of the environmental conditions in their habitat.

 

The text can be divided into four parts

Part I Pa1-3:   Darwin and his research.

Part II Pa4-5:  Mendel and his experiment.

Part III Pa6:  Turesson and his study

Part IV Pa7:  the importance and significance of the research of the three.

 Scanning

 1.(1) What did Darwin discover about  bird species in Galapagos?

           Darwin found 13 kinds of finches, related to each other in the structure of their beaks, tails, shape of body and colors of their feathers. The most curious fact was the differences in the size of the beaks.

 (2) What did Mendel observe in his  experiments with peas?

         In his experiments with peas, Mendel observed that many characteristics were passed on from one generation to the next, without influence by the environment.

 (3) Looking at wild plant species in  Sweden, what did Turesson discover?

        Looking at wild plant species in Sweden, Turesson discovered that plants changed their appearance and adapted to the new environment if they were moved to the other type of habitat.

 (4) What were Darwin’s discoveries  based on?

        Darwin’s discoveries were based on his observation in Galapagos.

   2. Why are Turesson’s discoveries still   important to agriculture then?

 Because different soil conditions lead to different output of crops. That is, the soil conditions will greatly influence the growth and output of the crops.

Important sentences in the passage

1. It was Darwin’s visit on the Beagle to the Galapagos Isles that gave him the key to his new theory.

2. Back home, in England, Darwin realized that differences in habitat could lead to different species in birds as well as in plants.

3. As a result of Darwin and Mendel’s research, scientists of the nineteenth century formed the belief that that influence of the environment was behind the development of new species.

4. It would take a next generation of scientists to bring the importance of the environment on species back in view.

Homework

Make some observations of the plants somewhere in the wild areas as required in the textbook, but make sure you are in a safe distance. Make notes of your impressions of the plants. For this task, you can work in groups or pairs in a corporative way, and you must think of ways to describe what you have seen or done.

Grammar

Revision

Joseph Banks was born into a wealthy family, and he could have led a life of privilege, but from an early age, he had an appetite for knowledge, he wanted to make a career in science, he chose to pursue his passion to the full, so he devoted his money to the career, he took pain and effort to join the exploration, collecting every possible information about plants, he helped to develop the royal gardens into one of the greatest botanical gardens in the world, etc. He really contributed a lot to the science of botany. His devotion, his pursue for knowledge, his sacrifice will forever encourage us to embrace greater dream, to study and work hard to make our country richer, stronger and more beautiful.

Tell what is used as the Object.

Born in 1743, Joseph Banks played an important role in botanical research in the eighteenth century. 

(2) Even before going to Oxford in 1760, Banks showed an appetite for knowledge.

As a member of the Royal Society, the 25-year-old Banks paid 10,000 pounds for the equipment of the expedition.

(4) The Royal Society gave him the opportunity he had been waiting for.

Do you know who else joined Banks on the expedition with Captain Cook in 1768?

He asked explorers to send him new plant species from around the world, which he included in the collection at Kew Garden.

(8) He enjoyed spending hours in the greenhouses at Kew, among the strange plants from Southeast Asia.

The first “Tea Roses” from China came in a wide variety of pink tones, and it was Joseph Banks who introduced them to England at the end of the eighteenth century.   

(10) As a reward for his contribution to botany, Joseph Banks had a flower named after him.
