Would you believe that the first outstanding deaf teacher in America was a Frenchman? His name was Laurent Clerc. He became a friend of Thomas Hopkins Gallaudet and together they founded America' s first school for the deaf,

Laurent Clerc was born in a small village near Lyons, France, on December 26, 1785. When he Was one year old, he fell into a fire, losing both his hearing and his sense of smell.

At 12, Laurent entered the Royal Institution for the Deaf in Paris where he excelled in his studies. After he graduated, the school asked him to stay on as an assistant teacher.

Meanwhile, in America, Thomas Hopkins Gallandet was studying to be a minister. He was very concerned about the lack of educational opportunities for the deaf. Therefore, in 1815, Gallaudet sailed to London, England to seek ideas on how to teach deaf people. While he was there, he met a French educator of the deaf who invited him to go to Paris to spend three months learning at the Royal Institution for the Deaf, the school where Laurent Clerc was teaching. Gallaudet accepted the offer. The two worked and studied well together. When the time came for Gallaudet to return, he asked Clerc to come with him. Clerc accepted on one condition: that he would stay in America only a short time.

The two men set sail on June 18, 1816. The voyage across the Atlantic Ocean took 52 days; however, Clerc and Gallaudet put the time to good use. Clerc studied English, and Gallaudet studied sign language. They discussed the school for the deaf which they planned to open. On the long trip, they had many conversations about education and deafness. The year after they arrived, they founded a school for the deaf in Harford, Connecticut.

At the school, Clerc led a busy life. He taught signs to Principal Gallaudet; he taught the pupils; and he taught hearing men who came to the school to study deaf education.

In 1819, Clerc married Eliza Crocker Boardman, one of his pupils. They had six children. He retired from teaching in 1858. Although he had intended to return to France, he never did. He died on July 18, 1869 in the United States.

72. Why did Thomas Hopkins Gallaudet sail to London?

A. He needed to finish his studies to become a minister.

B. It was the easiest way to get to France.

C. He wanted to study their system of deaf education.

D. He wanted to marry Alice Cogswell.

73. From the information in this passage we can infer that ________.

A. Laurent Clerc was an intelligent man

B. Clerc had difficulties learning language

C. Clerc married Eliza in order to get his Green Card

D. Clerc was paid well because he made such important contributions to society

74. On their trip from Paris to America, Clerc and Gallaudet ________.

A. played cards and socialized

B. studied and discussed their plans for a deaf school

C. founded a school for the deaf

D. Gallaudet studied English and Clere studied Sign Language

75. Which is the right order of the things Clerc did?

A. Met Gallaudet, moved to America, got married, went to school in Paris.

B. Met Gallaudet, went to school in Paris, moved to America, got married,

C. Went to school in Paris, met Gallaudet, moved to America, got married.

D. Got married went to school in Paris met Gallaudet moved to America.

某探究性学习小组欲探究光滑斜面上物体下滑的加速度与物体质量及斜面倾角是否有关。实验室提供如下器材:

A.表面光滑的长木板(长度为L);B.小车;C.质量为m的钩码若干个;D.方木块(备用于垫木板);E.米尺;F.秒表。

实验过程:

第一步,在保持斜面倾角不变时,探究加速度与质量的关系。实验中,通过向小车放入钩码来改变物体质量,只要测出小车由斜面顶端滑至底端所用时间t,就可以由公式a=________求出a。

某同学记录的数据如下表所示:

根据以上信息,我们发现,在实验误差范围内质量改变之后平均下滑时间________(填“改变”或“不改变”),经过分析得出加速度与质量的关系为________。

第二步,在物体质量不变时,探究加速度与倾角的关系。实验中通过改变方木块垫放位置来调整长木板的倾角,由于没有量角器,因此通过测量出木板顶端到水平面高度h,,出倾角α的正弦值sinα=h/L。

某同学记录了高度和加速度的对应值,并在坐标纸上建立适当的坐标轴后描点作图如图,请根据他所作的图线求出当地的重力加速度g=________ m/s2。进一步分析可知,光滑斜面上物体下滑的加速度与倾角的关系为________。
