All living things must fight to stay alive. They have to feed on something and at the same time avoid being eaten. Therefore they have to solve this big problem of staying alive in their own way.

The danger of being eaten in the sea is great. Those plants and animals that do survive usually reproduce very fast and in great numbers.

Certain sea animals have defensive devices(装置) which help them to survive. The jelly fish have poisonous tentacles(触角) which are used for attack and defence.

Another method of survival which sea plants and animals use is disguise(伪装). They usually have the same color as their surroundings.

In order to stay alive, animals need to have good senses. Fishes have sharp eyes. Almost all animals are sensitive to touch. Fishes judge movements in the water by means of their lines. Fishes and other sea animals can hear well and many of them can make different types of warning sound.

A great woman once said, “Women must try to do things as men have tried. When they fail, their failure must be a challenge to others. “These are the words of US pilot Amelia Earhart（1897- 1937）, a pioneer in aviation（航空领域）, who was the first woman to fly across the Atlantic Ocean

Her story ended in mystery when she disappeared without a trace（踪迹）during a flight over the Pacific Ocean. Theories about what happened to Earhart were proposed, but nothing was ever confirmed—until now. A study published in March conducted by Richard Jantz from the University of Tennessee, US, determined that bones found in 1940 on a remote Pacific island belonged to Earhart. Following the discovery, the world’s memories of the legendary female pilot were brought back to life.

Earhart was born in 1897. When she was young, she was very interested in stories about women who were successful in male-dominated（男性为主的）professions, such as engineering and law. But in 1920, Earhart’s life changed after her first experience of being a plane passenger. As soon as the plane left the ground, Earhart knew that she loved flying, so she found herself a teacher and started to learn how to fly for herself. To pay for the lessons and buy a plane of her own, she took all sorts of jobs.

Inl932, Earhart flew solo（独自地）across the Atlantic, becoming the first woman ever to do so. She also designed a flying suit for women and went on to design other clothes for women who led active lives. When she was nearly 40, Earhart was ready for a final challenge—to be the first woman to fly around the world. Her first attempt was unsuccessful but she tried again in 1937 with her navigator（领航员）Fred Noonan. But one month later, they disappeared in bad weather in mid-flight.

Even though it’s still not clear how she ended up on the island, we’re one step closer to finding the answer. And no matter what, Earhart will be forever remembered as a brave pioneer, both as a pilot and as a woman.

1.When did Earhart first fly across the Atlantic Ocean alone?

A. In 1920.　　 B. In 1932.

C. In 1937.　　 D. In 1940.

2.What started Earhart’s interest in flying?

A. Her parent’s influence.　　 B. Her teachers’ encouragement.

C. Her first experience as a passenger.　　 D. Her childhood love for engineering.

3.Which of the following words best describes Earhart?

A. Open-minded and patient.　　 B. Creative and helpful.

C. Talented and outgoing.　　 D. Pioneering and determined.

4.What’s the article mainly about?

A. The discovery of Earhart’s bones.

B. What made Earhart a great pilot.

C. The inspiring life story of Earhart

D. Some possible causes of Earhart’s death.

We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.

If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）. Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.
