题目内容

Invisible ink has fascinated kids for generations. You might think that it would be difficult to make, but it’s not.

All you’ll need for this experient is some milk; some white paper; a clean cotton swab (药签) or small, clean paintbrush; the kitchen stove; and help from an adult. The most difficult part of this mini-project is choosing the message that you’ll write with your invisible ink. Maybe you’ll want to pretend that you’re a spy on a secret mission, writing messages that would lead to big, big trouble if they were discovered. Choose your words carefully.

All you need to do is, using the brush of cotton swab, write your message with milk on the paper. Don’t use a lot of milk and soak the paper. Use just enough to make a thin coating.

Once you’ve finished writing, ask the adult who’s helping you to turn on the kitchen stove to a low heat. Very carefully, using kitchen mitts ,hold the paper about a foot above the warm burner. If you don’t see results, you may have to make the burner a little hotter.

Do not, however, hold the paper low over the burner. As the paper heats up, your message will become brown and you’ll be able to see what was written. You want to know why? It’s because chemical compounds in the milk have a low burning point. When the paper gets warm, those compounds will heat up and trun brown, while the paper will be unaffected.

You also can try this experiment with other liquids, such as orange juice, lemon juice, vinegar, and apple juice. Just be sure to follow all safety rules and have an adult around to help you.

As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more.

Lewis and his co-workers carried out their study by videotaping (录像) the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children. “In general the more question-asking the parents do, the higher the children’s IQ scores,” Lewis says. “And the more children there are, the less question-asking there is.”

The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings (兄弟姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the table and walk around during dinner, chances are it’s the middle child.” There is, however, one thing that stops all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event.”

Let's face it-English is a crazy language. There is no egg in eggplant (茄子) nor ham in hamburger; neither apple nor pine in pineapple(菠萝). English muffins (松饼) weren't invented in England nor French fries in France. Sweetmeats are candies while sweetbreads, which aren't sweet, are meat.

We take English for granted. But if we explore its paradoxes (似是而非的说法),we find that quicksand(流沙) can work slowly, boxing rings are square and a guinea pig is neither from Guinea nor is it a pig.

If teachers taught, why didn't preachers "praught"? If a vegetarian eats vegetables, what does a humanitarian eat?

How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can a person be "pretty ugly"?

You will be very surprised at the unique lunacy(荒谬) of a language in which your house can burn up as it burns down, in which you fill in a form by filling it out and in which an alarm clock goes off by going on. Why is a "crazy man" an insult(侮辱), while to insert a comma and say "crazy, man" is a compliment (as when clapping for a Jazz performance).

English was invented by people, not computers, and it reflects the creativity of the human race (which, of course, isn't a race at all). That is why, when the stars are out, they are visible, but when the lights are out, they are invisible. And why, when I wind up my watch, I start it, but when I wind up this essay, I end it.

According to the passage, which of the following statements is TRUE?

A. A wise man is similar in meaning to a wise guy.

B. "An alarm clock goes on" and"An alarm clock goes off" are opposite.

C. Boxing rings are square rather than round.

D. Sweetmeats are sweet meat while sweetbreads are not sweet at all.

Which of the following pairs contains expressions that are opposite in meaning?

A. "A fat chance"and "a slim chance".

B. "To fill in a form"and "to fill out a form".

C. "Crazy man" and "crazy, man".

D. "Quite a lot" and "quite a few".

Which of the following statements about the English language is NOT true according to the passage?

A. It is a crazy language.

B. It reflects the creativity of the human race.

C. It was invented by the British people.

D. It can be quite irregular.

Several times my daughter had telephoned to say, “Mum, you must come and see the daffodils （水仙花）before they are over.” I wanted to go, but it was a two-hour drive from Lake Arrowhead. “I will go next Tuesday,” I promised, a little unwillingly, on her third call.

The next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn’s house and hugged and greeted my grandchildren, I said, “Forget the daffodils, Carolyn! The road is invisible （看不见的）in the cloud and fog, and there is nothing in the world except you and these children that I want to see!”

My daughter smiled calmly and said, “We drive in this weather all the time, Mum. You will never forgive yourself if you miss this experience.”

After about twenty minutes, we turned onto a small road and I saw a small church. On the far side of the church, I saw a hand-lettered sign that read “Daffodil Garden”.

We got out of the car and each took a child’s hand, and I followed Carolyn down the path. Then, we turned a corner of the path, and I looked up and gasped. Before me lay the most beautiful sight! There were five acres of flowers! “But who has done this?” I asked Carolyn. “It’s just one woman,” Carolyn answered. “That’s her home,” Carolyn pointed to a well-kept A-frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio （庭院）, we saw a poster. “Answers to the Questions I Know You Are Asking” was the headline.

The first answer was a simple one. “50,000 bulbs （鳞茎）,” it read. The second answer was, “One at a time, by one woman.” The third answer was, “Began in 1958.”

I thought of this woman whom I had never met, who, more than fifty years before, had begun -- one bulb at a time -- to bring the beauty and joy to the mountain top.

1.The author didn’t go to see the daffodils at first because _________.

A. she was not interested in them

A. She must be out of mind.

B. She acted as a gardener there.

C. It took her great determination to grow the daffodils.

D. She was poor and made her living by selling daffodils.

3.What could the author probably learn from this experience?

A. Nothing is too difficult if you put your heart into it.

B. We must put the interests of others above our own.

C. We can change the world by growing flowers.

D. It’s never too late to learn.

4. What would be the best title for the passage?

A. An Unforgettable Experience. B. Beautiful Daffodils.

C. One Bulb at a Time. D. I Love Daffodils.
