Too cold for recess?  School policies vary as much as temps

When is it too cold for schoolchildren to go outside for recess(课间休息)? The answer varies widely based on where a school is located and what the kids are used to.

Consider:  One northern Minnesota school says it has to be 15 below zero before kids are kept inside. But in areas along the East Coast, temperatures below 35 to 40 degrees could keep kids inside. Canceling recess because of the cold is no small issue considering that much of the USA is trembling through what may be its coldest winter in a generation, according to AccuWeather.

There is no national temperature standard for when to keep kids inside during the winter months, the U.S. Department of Education says. Decisions are made at the local level, either by principals or school districts.

Consequently, policies are all over the map:

• In International Falls, Minn., the self-described "Icebox of the Nation," where the average high temperature in January is 13 degrees, Falls Elementary School Principal Jerry Hilfer says, "if it's 15 below (or warmer), they go out, no matter what." "At 20 below, it gets iffy," he adds.

• In Wicomico County, Md., principals typically keep children indoors when temperatures drop below freezing, or if it's raining or snowing, says Susan Jones, the school system's director of elementary education.

"That's the bottom line," says Curtis Twilley, principal of Pemberton Elementary School in Salisbury, Md. Twilley says students get little exercise when recess stays indoors. At Pemberton Elementary, the students will typically play board games or computer games in a classroom because the school's gym is occupied with other classes, he says.

• For schools in Marquette, Mich., which averages about 12 feet of snow per season, school officials acknowledge students are probably a little more prepared than those in some more mild climates.

1.Which of the following is not true according to the passage_________.

A. No national temperature standard is made for when to keep kids inside during the winter months

B. Susan Jones insists students get little exercise when recess stays indoors.

C. In Wicomico County, children are kept indoors when temperatures dip below freezing.

C. physical activity can boost student performance.  D. decisions are made at the local level,

4.The underlined word iffy means _______.

A. uncertain                  B. surprising           C.  serious  D. worse

 A warm blanket is the ideal sleep aid for a freezing winter night. The right blanket can warm your bones but the wrong one can affect your sleep. I asked experts for advice on picking the perfect blanket for a good night’s sleep. Here’s what they told me.

     When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. “People seem to sleep best at temperature between 62 and 70 degrees F,” says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can rouse you from sleep. A good blanket helps drive the coldness away.

     At the other extreme, overheating yourself can affect your sleep as well. “Core body temperature typically drops during the first four hour’s of sleep,” says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep.

     “In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control,” says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe.” This is the reason why many people like to sleep under a blanket even in summer.

     “If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults,” Moor says. She adds that weighted blankets are not recommended for those recovering from surgery.

     “People can also have serious preferences for a particular blanket,” says Dr. Hoagland. “Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker.” In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily.

1.The author wrote the passage mainly to tell us _____.

A. the importance of blankets

B. how to choose the perfect blanket

C. different materials used to make blankets

D. the history and usage of blankets

2.The underlined word “rouse” in Paragraph 2 is the closest in meaning to “______”.

3.What do we know from the passage?

A. Body temperature rises when we fall asleep

B. The perfect sleep temperature should be above 70 degrees F.

C. Weighted blankets should be at least 30 pounds.

D. People are advised to use their own blankets.

 

Lettuce (莴苣)has been eaten for over 4,500 years, and was known to the Egyptians, Greeks and Romans. Now, people in some countries start the meal with lettuce as part of a salad. There are hundreds of kinds of lettuce. The main ones include head lettuce, such as iceberg, leaf lettuce ,Boston, bibb and romaine.

Experts say lettuce is one of the easiest crops to grow in your garden. The best time to plant the seeds is during cool weather. The University of Illinois Extension advises that the best planting temperature is 15 0C.

Lettuce seeds are small, so do not place them too deep in the ground. If you plant some seeds every week or two, you will have crops ready to eat one after another.

To start the seeds inside, you can use a seed tray in your home or other shelter. This container should be deep enough to hold at least three centimeters of soil or more. There should be about one centimeter of space between the soil and the top of the container. The container should have holes in the bottom so the extra water can flow out. Drop the seeds over the surface and cover them lightly with soil. If the soil is not already a little wet, give it some water. But do not drown the seeds.

Next, cover the seed tray with paper. When the seedlings have come up far enough to touch the paper, take it off. You can transplant the seedlings into the garden when they are about two to three centimeters tall. Do this when the weather is not too hot and not too cold. Take out as much soil as you can with the seedlings, Then dig a hole in the ground bigger than the lettuce roots. Water the plants but not too heavily.

Harvest leaf lettuces when the leaves are big enough to eat. Pull the leaves from the outside of the planting so the inside leaves will keep growing. Or, you can cut off the whole plant. Leave about two or three centimeters above the ground so the plant will re-grow. Cut off head lettuces at ground level.

Lettuce is best when served fresh, so make a salad and enjoy. Experts say lettuce is one of the easiest crops to grow in your garden.
