Mr. Klein told the class that a new student, Inez, would join them soon. He 1 that Inez was deaf. She “talked” with others by using sign language. Mr. Klein knew sign language, and he decided to teach 2 students so that they could also “talk” with Inez.
    First, they learned to sign the letters. Some letters were hard to3 . Other letters, such as C ,were easier because the shape of the hand was the same as the shape of the letter.
    The 4 thing they learned was finer spelling. They signed one letter after another to spell a word. They5with two-letter words such as at and on . Then they spelled 6words.
    Finally, Mr. Klein showed that 7 one sign could be used for a whole word. To make the sign for the word fine, a person spreads out the fingers on one hand, 8 the thumb(拇指) to the chest(前胸) , and moves the hand away from the chest. Signing is not just done with the hands. Expressions on the face are also9  . The students learned to sign a question mark by using expressions on the face.
When Inez first entered the classroom. She looked  10 . But the students signed, “Good morning, Inez. ” She gave the class a big smile and signed back, “What a wonderful welcome !”
