Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released five simple rules for preparing food in a safe way. 1.

Key 1: Keep clean.

The first key tells about the importance of washing. People should wash their hands often—before touching food, while they are preparing food, and any time after they go to the toilet. People should wash all surfaces and equipment used for preparing food. 2.

Key 2: 3.

People should separate raw, or uncooked food from foods that are already cooked and foods that will not be cooked. People should store raw meat, chicken, and fish in containers, or in separate areas. Raw foods should not touch prepared foods.

Key 3: Cook completely.

People should cook eggs and meat, like birds, seafood, and animals, especially carefully. These foods may carry more micro-organisms than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.

Key 4: Keep food at safe temperatures.

When people are finished with eating, they should keep the left food in a refrigerator below 5℃ and shouldn’t store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. 4. They cannot grow as quickly in a very hot or very cold environment.

Key 5: Use safe water and raw materials.

5. Damaged or old food may develop harmful chemicals as it gets older.

A.Eat cooked food immediately, while it is still hot.

B.They call these rules the “Five Keys to Safer Food.”

C.Separate raw and cooked.

D.People should use safe water and choose fresh foods.

E.Keeping everything clean helps people to avoid micro-organisms.

F.People should also protect cooking areas and food from insects and animals.

G.But temperatures above 60℃ or below 5℃ control the growth of micro-organisms.

About 1966 or so, a NASA (美国航空航天局) team doing work for the Apollo moon mission (任务) took the astronauts near Tuba City. There the landscape of the Navajo Reservation (保留地) looks very much like the lunar surface. Among all the trucks and large cars were two large figures that were dressed in full lunar space suits.

Nearby a Navajo shepherd (牧羊人) and his son were watching the strange creatures walk about, occasionally being watched over by other NASA workers. The two Navajo people were noticed and approached by the NASA people. Since the shepherd and his son did not know English, they asked the NASA people who the strange creatures were. The NASA people told them that they were just men that were getting ready to go to the moon. The shepherd became very excited and asked if he could send a message to the moon with the astronauts.

The NASA officials thought this was a great idea so they provided a tape recorder. After the man gave them his message, they asked his son to translate. His son would not.

Later, they tried a few more people on the reservation to translate and every person they asked would chuckle (偷偷地笑) and then refuse to translate. Finally, with cash in hand someone translated the message,

“Watch out for these guys, they have come to take your land!”

Some people surveyed tasted the sweet, salty and crunchy together with other tastes of food as they listen to different noises.It shows that louder noises reduced the reported sweetness or saltiness of food while incr eatasing the measure of crunchiness（松脆）.

It may go some way to explain Why airline food is widely complained about by both the workers and paddengers.Andy Woods,a researcher,said,“It's a general opinion that plane foods aren't fantastic,but I'm sure airlines do their best,so we wondered if there were other reasons,One thought was that perhaps the background noise may have an effect.NASA gives their space explorers very strong -tassting foods,because for some reason,they can't taste food that Strongly-^again, it may have something ti do with the background noise.”

In a studr ,48 people were fed sweet foods or salty ones, while listening tonoting or noise through earphone. Meanwhile they rated(划分等级) the foods. In noisier settings,foods were rated less or sweet than they were when it was silent,but were rated crunchier.“The evidence shows that if the background noise is loud,your food,

attention might be drawn to that, away from the food.” Dr. Woods said.

“We ae still at an early stage of progressing and this is a rather small study to really draw definitive(最完整可靠的）conclusions from,” Dr Woods said,“but they suggest that restaurants could well their choice of food for a given environment.”

Also in the group's findings there is the suggestion that the overall satisfaction with the food is also related to the degree to which people like what they are hearing .

It is like a scene from a horror film：a spider web is several meters wide，which is home to thousands of spiders.And that was what Jason G．Goldman，an animal behavior researcher，found along a muddy path in the Peruvian Amazon jungle—the web arched from tree to tree，a structure containing too many spiders to count.They appeared to function as a society，just like ants or bees.

Anelosimus eximius，the species Goldman met in the rainforest，is not the only kind of social spiders in the world，but it does construct the biggest webs.Some can reach more than 7.6m long and 1.5m wide.A web of that size could contain as many as 50,000 individual spiders.

Anelosimus eximius was first discovered more than a century ago by a French scientist named Eugene Simon.More social spiders have been discovered since.One was found as recently as 2006.

An Anelosimus eximius colony(群体) contains adult males and females as well as youngsters，but the majority of spiders on the web are females. Males account for only between 5% and 22% of any colony’s population.Social spiders work together to build，maintain and clean their webs.They work together to catch prey(猎物)，and dine together when they trap a large feast.The females work together to care for the young in the colony.They feed their youngsters by vomiting(吐出) up food for them，just like mother birds.

Why did these spiders become social？Researchers have discovered three ecological(生态的) elements that often lead to cooperative(合作的) living among spiders.

Social spiders tend to feed on bigger prey，for one thing.Spiders living in places where it is difficult to hunt large or more profitable prey alone may eventually figure out that it is in their interest to work together.

1.What can we know about Anelosimus eximius from the text?

B. It was discovered by Jason G．Goldman.

C. It has been in existence for less than a century.

C. They live and work together.

D. They mainly exist in the rainforest.

An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son.
