2 . Help Hermit Crabs
Hermit crabs are nature’s recyclers. They eat waste and help keep oceans and shores clean. Unlike other crabs, the hermit crab has a thin outer shell over its soft tail. This makes the hermit crab easy prey for hungry predators. Hermit crabs stay safe by living in old seashells. A hermit crab is picky; it tries on many shells until it finds one that fits just right. In recent years, however, many hermit crabs have had trouble finding their perfect homes. What is the problems There are not enough shells to go around!
One reason for the seashell shortage is that ocean water is not as clean as it once was. This has caused chemical changes to sea water. Some sea animals, like snails, are affected by these changes. Now there are fewer snails making shells. People visiting the beach often take shells home as souvenirs. This is another problem. Other people even take shells for their own pet hermit crabs! They do not realize that hermit crabs in the wild need those shells too.
Now people are working to solve this hermit crab housing shortage. They are teaching beach-Boers to leave seashells where they belong — at the seashore! Some people even make fake seashells that they hope the hermit crabs will like. For example, a group called Project Shelter invited people who visited their website to create different designs for hermit crab shells.
These designers had a lot to consider. What kind of material should be used to build a seashells. The material must be light enough for the hermit crab to carry, but strong enough to protect the crab from predators. The man-made shells could not contain glue or any other substance that might harm a hermit crab. Another challenge with building a hermit crab home was the opening to the shell. Too big would mean the crab would not feel safe. Too small would be uncomfortable, and the crab would not want to move in.
The Project Shelter shells are placed in the wild for hermit crabs to find. Lucky hermit crabs can move into these new dream homes.

3 . He knew his colors and shapes, he learned more than 100 English words, and with his own brand of one-liners he established (确立) himself in TV shows, scientific reports, and news articles as perhaps the world’s most famous talking bird.
But last week, Alex, an African parrot, died, obviously of natural causes, said Dr Irene Pepperberg, an expert at Brandeis University and Harvard who studied and worked with the parrot for most of its life and published reports of his progress in scientific journals. The parrot was 31.
Scientists have long debated whether any other species can develop the ability to learn human language. Alex’s language ability was, in some ways, more surprising than the efforts of those animals that have been taught, like Koko, the gorilla (猩猩) trained by Penny Patterson at the Gorilla Foundation in Woodside, or Washoe, another gorilla studied by R. Allen and Beatrice Gardner at the University of Nevada in the 1960s and 1970s.
When Dr Pepperberg, who was then a doctoral student in chemistry at Harvard, found Alex was good at remembering words in a pet store in 1977 and bought it, scientists had little expectation that birds could learn to communicate with humans. Most of the research had been done on pigeons, and was not promising.
But by using novel methods of teaching, Dr Pepperberg taught Alex to learn about 150 words, which he could put into categories. He could count small numbers and tell colors and shapes. “The work changed the way we think of bird brains,” said Diana Reiss, a psychologist at Hunter College who works with dolphins and elephants. “We used to look down upon those birds, but now we look at those brains — at least Alex’s — with some awe.”
