There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community(医学界) a method of fighting heart disease, has had some unintended side (effect) such as overweight and heart disease—the very thing the medical community was trying to fight.

Fat and salt are very important parts of a diet. They are required (process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt 64 (remove) from food, the food tastes as if is missing something. As result, people will eat more food to try to make up for that something missing. Even (bad), the amount of fast food that people eat goes up. Fast food (be) full of fat and salt; by (eat) more fast food people will get more salt and fat than they need in their diet.

Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be (care) not to go to extremes. Like anything, it is possible to have too much of both, is not good for the health.

B

I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.

I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.

I examined the chick(雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.

The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

A nervous night to be sure,but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH!The parents had done their duty and would probably continue to do so.

Scientists have found living organisms trapped in crystals(晶体) that could be 50,000 years old.

The organisms were found in a hot, but beautiful cave system in Naica, Mexico. These ancient life forms can be seen only with a microscope. Penelope Boston, who leads the Astrobiology Institute at NASA, the space agency of the United States, says the ancient microbes(微生物) were able to live by eating minerals such as iron.

She spoke about the discovery recently at a meeting of the American Association for the Advancement of Science. If the findings are confirmed, they will show how microbes can survive in extreme conditions. Forty different kinds of microbes and some viruses were found in the underground area. The genetic structures of these organisms are 10 percent different from those of their nearest relatives.

The caves in Naica are 800 kilometers deep. They were once used for mining lead. Before the miners began working in the caves, the area was separated from the surface and the outside world. Some of the caves are as big as the large religious centers built during Europe's Middle Ages. There are crystals covering the walls. The caves are so hot that scientists must wear special clothing to keep cool. The clothing keeps the crystals safe from human germs(病菌)or other damage. Boston said the researchers could only work for about 20 minutes at a time before they had to go to a room that was 38 degrees Celsius to cool down.

NASA officials would not let Boston share her findings with scientific experts before last week's announcement. So scientists could not say much about the findings. But Norine Noonan, a biologist with the University of South Florida, said she believed them. "Why are we surprised?" Noonan asked. "As a biologist, I would say life on Earth is extremely tough and extremely colorful."

Boston is also studying microbes commonly found inside caves in other countries, such as Ukraine and the United States. These microbes appear to be impossible to kill. Boston said they show how difficult life on Earth can be.

1.The existence of the ancient microbes relies on _______.

A. surrounding insects B. diverse plants

C. eating minerals D. absorbing air

2.What can we infer about the caves in Naica from the passage?

A. The walls are covered by crystals.

B. The temperature in the caves is quite low.

C. The caves have been explored since they were formed.

D. The environment in the caves is difficult to adapt to.

3.What is the biologist Norine Noonan’s attitude towards the findings?

A. Critical B. Positive.

C. Doubtful. D. Indifferent.

4.What’s the main idea of the passage?

A. Living organisms bring hope to scientific research.

B. Scientists Discover 50,000-year-old “super life” in Mexico.

C. Microbes show great power to survive in terrible conditions.

D. Caves provide living environment for living organisms.

You may use banknotes every day. But did you know that there is a lot of science behind the money? 1.

Australia was the first country to use polymer(聚合物)banknotes in 1988. 2.

They can stop water from making them wet. They are also cleaner because bacteria don’t grow easily on them.

Now, the Australians have improved their banknotes again by creating a new 5-dollar note. The new one has a clear window in the middle in which there are pictures of an Australian bird and a building. 3.

Tilt (倾斜)the note a little and you will see the bird flapping its wings as if trying to fly away. Turn the note from side to side and you will notice the building come to life and spin. While these features are impressive and entertaining, that was not the reason why the Australian Government spent ten years perfecting them. Their primary purpose was to make it impossible to fake a banknote.

4. The new $ 5 bill now has a raised bump alongside the two long edges, enabling the blind or those with limited vision, to quickly determine its value.

The Australian government will give the new 10-dollar note the same features in a year’s time. 5.

A. Note makers still have a long way to go.

B. Other notes will have them in the future.

C. The magic of the new features lies in them.

D. They have many advantages over paper notes.

E. The new Australian 5-dollar note is a good example.

F. The new note is also the first touchable Australian banknote.

G. Their material and pattern set them apart from ordinary banknotes.
