But he was bothered by his easy and quick decision of leaving the young man stranded alone in the desert.3) Why did the author decide to start his journey across America pennilessly?He wanted to test if a person could still rely solely on the kindness of strangers or the good will of his fellow Americans these days.4) What did he discover as he travelled?He found out that others shared his fear.

Write down the main idea of each part.Part: One; Paragraph(s): 1–7; Main Idea: Because of a past experience of neglecting a hitchhiker in need of help, the author decided to travel across America without any money to find out if one could still rely on the kindness of strangers these days.Part: Two; Paragraph(s): 8–28; Main Idea: During his trip, he found out that people were generally compassionate and willing to help although they might have fears.Part: Three; Paragraph(s):29-31; Main Idea: He talked to school children and concluded in a patriotic manner that in America people could still depend on the kindness of strangers.Task Two Reading Between the LinesRead the following sentences carefully and discuss in pairs what the author intends to say by the italicized parts.1) In the middle of the desert, I came upon a young man standing by the roadside. He had his thumb out and held a gas can in his other hand. (Para. 1)By doing so, the young man was telling the passing drivers that he wanted to hitchhike as his car had run out of gas.2) The week I turned 37, I realized I’d never taken a gamble in my life. (Para. 7)This week I would be 37 years old, yet I realized that I had always been very careful in my life and I had never taken a risk, for example, trusting on the kindness of others.3) It would be a cashless journey through the land of the almighty dollar. (Para. 7) The author is being a bit sarcastic here. He would take no money with him and travel across the US, where it is believed that money can do everything and anything. The phrase "almighty dollar" is a playful allusion to the familiar term "Almighty God"4) Yet I was treated with kindness in every state I traveled. I was amazed by the stubborn capacity of Americans to help a stranger, even when it seemed to run contrary to their own best interests.

(Para. 13)The author had mixed feelings: whether to kiss the two women for their kindness, or give them a lesson by cautioning them not to trust any stranger, for they could have run into a bad person instead of himself.Checking Your VocabularyWord Detective1 Choose the definition in Column B that best matches each italicized word in Column A.1) c2) d3)a4) j5)h6)b7) e8) i9) g10) f2 A synonym is a word that has the same or nearly the same meaning as another word.

Under such circumstances, names are no longer important.3) What can we learn about the silent woman from Para. 5?The silent woman always s its up front and never responds to others’ greetings.

The passengers are all delighted to have their company. They always chuckle and nod when the Haitians are all aboard.8) Why is the woman who sits up front always silent?She has a speech impediment. Talking is hard for her.9) What do you know about the silent woman’s family life?She is a single mother with a disabled son who is receiving special care away from home.

The Sunday-morning bus ride is the best thing she does all week, and an occasional visit to the fish restaurant is almost as good as the second best thing. She rides the Sunday-morning bus simply for the companionship of the driver whose name she doesn't know, but who appreciates the hot coffee she brings.10) How did the author and his wife feel about the dinner with the silent woman? They all had a wonderful time. For the silent woman, an occasional visit to the fish restaurant was a pleasant experience and this time it was even better with the companionship of the author and his wife.
