Homemade Ice Cream in a Bag
Difficulty: Very Easy
Average User Rating:★★★★☆(4.3/5)
Milk can become homemade ice cream in five minutes by using a bag! This homemade, creamy treat is a summertime delight for your kids and you alike.
What you’ll need:
1 tablespoon of sugar; 1/2 cup of milk; 1/4 teaspoon of vanilla (香草香精); 6 tablespoons of rock salt; 1 small-sized plastic food storage bag; 1 gallon-sized plastic food storage bag; ice cubes.
How to make it:
l Fill the large bag half full of ice, and add the rock salt. Seal the bag.
l Put milk, vanilla, and sugar into the small bag, and seal it.
l Place the small bag inside the large one, and seal it again carefully.
l Shake until the mixture turns into ice cream, which takes about five minutes.
l Wipe the top of the small bag, and then open it carefully. Enjoy!
Tips:
1/2 cup of milk will make about one spoon of ice cream, so double the recipe if you want more. But don’t increase the amount more than that—a large amount might be too big for kids to pick up because the ice itself is heavy.
Here is another version of the homemade ice cream recipe from another parent!
These are the homemade ice cream ingredients:
1/4 teaspoon of vanilla butter and nuts; 1 tablespoon of sugar; 1/2 cup of milk.
These are the other supplies:
Plastic sandwich bag; 12 salt pellets; 1 dish of ice; large plastic bag.
Put the ice cream ingredients in the small bag, and then put the bag, salt and ice in the big bag. Hold the bag shut and move it around on the floor for about 5 minutes.
When I made ice cream at home last time, although the salt pellets didn’t really dissolve (溶解) that well, I still got ice cream. It was not smooth ice cream, probably because of the low-fat milk. It was incredible that it could be ready in 5 minutes (not counting preparing the ingredients)
Next, I changed the recipe, using a tablespoon of cocoa, a tablespoon of sugar, and a cup of milk. It was a bit too chocolaty, but good!The underlined “that” in “Tips” section refers to ____.
| A．1/2 cup of milk | B．1 cup of milk |
| C．1 spoon of ice cream | D．2 spoons of ice cream |
Which of the following things is NOT included in both recipes?
| A．Sugar | B．Ice | C．Plastic bag | D．Nuts |
Which of the following statements about the second parent is TRUE?
| A．He/ She doesn’t agree with the first parent. |
| B．He/ She doesn’t think five minutes is enough |
| C．He/ She doesn’t like cocoa better than nuts. |
| D．He/ She doesn’t think the chocolaty tastes bad. |
The massive 8.8 quake, the seventh strongest in recorded history, hit Chile（智利） and should have shortened the length of an Earth day by 1.26 milliseconds. More impressive is how much the quake shifted the Earth’s axis（地轴）.
The computer model used to determine the effects of the Chile earthquake effect also found that it should have moved the Earth’s figure axis by about 8 cm. The Earth’s figure axis is not the same as its north-south axis, which Earth turns around once every day at a speed of about 1,604 kph. The figure axis is the axis around which the Earth’s mass is balanced. It is offset（偏离）from the Earth’s north-south axis by about 10 meters.
Strong earthquakes can change Earth’s days and its axis. The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami（海啸）, should have shortened Earth’s days by 0.0068 milliseconds and shifted its axis by about 7cm.
One Earth day is about 24 hours long. Over the course of a year, the length of a day normally changes gradually by one millisecond. It increases in the winter when Earth moves more slowly, and decreases in the summer.
The Chile earthquake was much smaller than the Sumatran quake, but its effects on the Earth are larger because of its location. The fault（断层） responsible for the 2010 Chile quake also cuts through Earth at a larger angle(角度) than the Sumatran quake’s fault. This makes the Chile fault more effective in moving the Earth’s mass vertically and hence more effective in shifting the Earth’s figure axis.
The findings are based on early data available on the Chile earthquake. The Chile earthquake has killed more than 700 people and caused widespread damage in the South American country.

Until quite recently, I knew only three things about my father: I knew his name, David S. Johnson, Jr. I knew he was an only child, and I’d been told he was killed on April 12, 1945, somewhere in Germany.
I used to come to visit my Granny. “Daddy David and his two friends were out in the fields, making sure the way was safe for the others to follow,” she told me. “All of a sudden there was an explosion. All three of them were killed.” Granny was looking down, stroking (抚摸)one thin hand with the other. Then there were no words but silence.
I began my search and collection for information about my father as my 50th birthday and the 50th anniversary of his death drew near. I was told that the explosion had blown him to bits and I had great difficulty collecting anything I could find about him bit by bit. Bits of information about his began falling into my hands, my mind and my heart. Longing to know my father kept me connected to him. It was time to transform my longing into knowledge.
Once upon a time he was alive, and my mother and father were deeply in love. They were married, and they had a child, my brother David. Then my father left for the war.
I was born in January 1945. On February 15 my father wrote me a letter of welcome. The letter is kept in my baby book, “Dear Susan, you have a very good family. Your dad is sort of a less able person. Your mother is the most wonderful person I’ve ever known. I’ve always marveled at my great good fortune to have her and been loved by her. If you follow her words and examples, you may expect to meet life in the best possible way, and your path will always be the right one. Your father, Dave.”
Black on white paper, the words are from my father. From them I grow into a person of loyalty and love. How I long for stories that will bring him to life!

The United States is on the verge of losing its leading place in the world’s technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S. scientists and engineers.
Since 1976, employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-old the near term source of future PhDs is declining. Further adding to the problem is the increased competition for these candidates from other fields law，medicine，business，etc. While the number of U.S. PhDs in science and engineering declines，the award of PhDs to foreign nationals is increasing rapidly.
Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor‘s and Master‘s degree holders. Too often，promising PH.D.candidates, confronting(面临) the cost and financial sacrifice of pursuing their education, find the attraction of industry irresistible.
1. The U.S.will come to lose its leading place in technology probably because ________.
A. scientists and engineers are not employed
B. the number of PH.D. degree holders is declining
C. the number of scientists and engineers is decreasing
D. the number of 22-year-ilds is declining
2. The field of science and engineering is facing a competition from ________ .
A. postgraduates
B. technology
C. such fields as law，medicine and business
D. foreign nationals
3. Large-scale enterprises now need _______.
A. new inventions B. engineers
C. advanced technology D. bright graduates and postgraduates
4. PH.D. candidates "find the attraction of industry irresistible" means that _________.
A. they cannot work for industry any longer
B. they find industry is attracting more and more college students
C. they don’t think they can prevent themselves from working for industry
D. they cannot resist any attraction from all sides
More than 2 million US teenagers have suffered a serious bout（发作) of depression in the past year, according to a federal government survey released on Tuesday.
On average, 8.5 percent of adolescents aged 12 to 17 described having had a major depressive episode in the previous year, the Substance Abuse and Mental Health Services Administration reported.
But there were "striking differences" by sex, with 12.7 percent of girls and 4.6 percent of boys affected.
Depression is the leading cause of suicide, which in turn is the third-leading cause of death for 15- to 24-year-olds in the United States.
"Combined 2004 to 2006 data show that rates of past year major depressive experience among youths aged 12 to 17 generally increased with increasing age," the researchers wrote.
Researchers at SAMHSA and RTI International in Research Triangle Park, North Carolina, prepared the report using data from the National Survey on Drug Use and Health.
More than 67,700 youths aged 12 to 17 answered questions about mood and depression. They were also asked to rate how depression affected them using the Sheehan Disability Scale, which measures impact on family, friends, chores at home, work and school.
Researchers defined a major depressive episode as two weeks or longer of depressed mood or loss of interest or pleasure, and at least four other symptoms(症状) such as problems with sleep, energy, concentration or self-image.
Nearly half of the teenagers who had major depression said it severely damaged their ability to function in at least one of the areas on the disability scale.
"Fortunately, depression responds very well to early intervention and treatment," SAMHSA Administrator Terry Cline said in a statement.
