Transcript 马丽u20 l3 scientific breakthrough

Lesson 3
Objectives
In this period, you will be able to:
• expand knowledge of some scientists and their
breakthroughs
• know the influences of them and develop an
interest in science
• improve reading strategies for identifying
accurate information.
Pioneers of science
&
their scientific breakthroughs
…
Let’s have a quiz about
scientists and their discoveries
with respect and great
gratitude
1. A British scientist(1808 -- 1882). He laid the
foundation of modern evolutionary theory. The
Origin of Species was published in 1859. And he
argued for the “Survival of the Fittest”: the biggest,
the smartest and the strongest are not the survivors.
Rather, the survivors are the most adaptable.
Charles Darwin
2. An American inventor (1847-1922), best known
for the development of the telephone and the
foundation of the Bell Telephone Company. In
1876, his "electrical speech machine," which we
now call a telephone, was born.
Alexander Graham Bell
3. A French scientist(1867--1934). She was born in
Poland and in 1891 she came to study in France, where
she married Pierre Curie. In 1898 she discovered
radium. She received two Nobel prizes, one for physics
(1903) and one for chemistry (1911).
Marie Curie
4. An American scientist (1847- 1931). He was an
inventor of many electrical devices such as electric
light bulb and is considered one of the most prolific
inventors, holding a record of 1,093 patents to his
name.
Thomas Edison
5. A great Chinese agriculturalist(1930-). He
invented a new species that produced a 20 percent
higher yield(产量) than common types of rice and is
known as China’s “father of hybrid(杂种的)rice”.

Second-reading Reading strategy 2: identifying
accurate information
a strategy to deal with
True or False Details (细节理解题之判断正误)
Steps:
• Read the questions / statements and identify key
words.
• Find the relevant (相关的）part of the text and
identify the key words .
• Decide if these key words express the same ideas.
• To decide if there is no information, make sure
that the answer (true /false) cannot be inferred
from the text.
Base your decision only on the information in the text!
True or False Details (细节理解题之判断正误)

• 偷换概念、张冠李戴
• 添油加醋、半真半假
• 断章取义、以偏概全
• 片面绝对、过度引申
• 凭空捏造、无中生有
• 曲解原意、混淆视听
True or False Details (细节理解题之判断正误)
1. According to the passage, which of the following
statements is true? ____
C
A. Einstein was at work when he thought of the
equation “E=mc2 ”.
凭空捏造 无中生有
… was rocking his one-year-old baby when he was suddenly
inspired. “E=mc2”was born.
B. Einstein participated in the program that
developed the nuclear bomb. 凭空捏造 无中生有
C. Hubble discovered that our galaxy is bigger
than we thought it was.
He discovered …which proved that the universe was vastly
larger than had previously been thought.
D. There was a blue mould around the bacteria in
the dish left by Fleming. 曲解原意、混淆视听
He... saw a blue mould in the dish around which the bacteria
had been destroyed.
