    Four Wild Animal Species Were Endangered

    Maybe you can still see them at the zoo. But that doesn’t mean they’re doing alright in the wild.

    Tigers

    All six tiger species are endangered, with Sumatran tigers and South Chin tigers at a seriously endangered status. The main reasons for their population decline are illegal hunting and destroyed habitats(栖息地), as humans clear forests to gather timber（木材）and build roadways. Only about 3890 tigers presently live in the wild.

    Ground squirrels

    That’s right, even squirrels are endangered, specifically the San Joaquin ground squirrel. Native to California, USA, these guys have been disappearing since 1979 on account of the construction and human developments going through their habitat. Their total population is unknown , but it could be anywhere between 124000 and 413000.

    Giraffes

    The International Union for the Conservation of Nature recently put giraffes at a vulnerable status, the level just before endangered. The giraffe population has declined 40 percent in the last 30 years, primarily due to loss of habitat and illegal hunting. Some giraffes are killed just for their tails, which are considered status symbols in Africa.

    Asian elephants

    The main threat to Asian elephants, one of the most intelligent animals, is their shrinking habitat. As the human population grows, people invade their land to build roads and railway tracks. Elephants in Myanmar are at an especially high risk for being captured and traded or used illegally in the tourist industry. Fewer than 50000 are left on the entire continent.

    1.What is the total population of tigers living in the wild?

    A. Around 3890.

    B. 50000.

    C. 124000.

    D. 413000.

    2.Which of the following is considered one of the most intelligent animals?

    A. Tigers.

    B. Giraffes.

    C. Ground squirrels.

    D. Asian elephants.

    3.What is the common threat to the four wild animals?

    A. Illegal hunting.

    B. Disturbed habitat.

    C. Developing tourism.

    D. Unnecessary construction.

    4.Which word can best describe the present situation for protecting wild animals?

    A. Satisfactory.

    B. Optimistic.

    C. Urgent.

    D. Stable.

    It was a cold March day in High Point,North Carolina.The girls on the Wesleyan Academy softball were waiting for their next turns at bat during practice,stamping their feet to say warm.Eighth-grader Taylor Bisbee shivered（发抖）a little as she watched her teammate Paris White play.The two didn’t know each other well—Taylor had just moved to town a month or so before.

    Suddenly,Paris fell to the ground,“Paris’s eyes rolled back,”Taylor says.“She stated shaking.I knew it was an emergency.”

    It certainly was,Paris had suffered a sudden heart failure.Without immediate medical care,Paris would die.At first,no one moved.The girls were in shock.Then the softball coach shouted out,“Does anyone know CPR?”

    Taylor’s swift action helped her teammates calm down.One girl called 911.Two more ran to get the school nurse, who brought a defibrillator,an electronic devices（器械）that can shock the heart back into work.Luck stayed with them: Paris’ heartbeat returned.

    “I know I was really lucky,”Paris says now.“Most people don’t survive this.My team saved my life.”

    Experts say Paris is right: For a sudden heart failure,the single best chance for survival is having someone nearby step in and do CPR quickly.

    Today,Paris is back on the softball team.Taylor will apply to college soon.She wants to be a nurse.“I feel more confident in my actions now,”Taylor says.“I know I can act under pressure in a scary situation.”

    Feet help us walk, run, dance, and jump. The words feet and foot are also used in everyday speech.

    To be under someone’s feet means to be troublesome. In other words, you are standing too close to someone and are getting in their way. Some adults criticize (批评) children for being under foot.

    Speaking of children, if someone says their home will soon have the pitter-patter of tiny feet, it means the family is expecting a baby!

    Now, people who are active do not let grass grow under their feet. They are never in one place for very long. People who can think and take action at the same time are said to be able to think on their feet.

    Some people appear to have it all. They have money, a good education, good looks, a great family and a large circle of friends. You could say they have the world at their feet. This means whatever they want seems to be there for them.

    People who have both feet firmly on the ground are realistic and practical. They are not dreamy. You might say such a person is well grounded. If you are a bad dancer, you might be described as having two left feet. To dance well, it is better to have a right foot and a left foot.

    Sam loves skiing. He thinks that it would be fun to own a ski resort (滑雪场) high in the mountains. But he knows nothing about running a business. So, he decides to get his feet wet. In other words, he wants to get used to a new situation.

    He joins an organization for resort owners and attends their meetings. He travels to ski areas all over the United States. This helps Sam get his foot in the door. Having a foot in the door is a starting point. This expression comes from people selling things door-to-door. They would block the door with their foot so people couldn’t close the door on them.

    1.What would you say to someone who is “under your feet”？

    A. Oh, I’m terribly sorry.

    B. Take off your feet!

    C. Sorry for the trouble.

    D. Excuse me, you are in the way.

    2.Which of the following describes people who keep moving about?

    A. They are always under foot.

    B. They can think on their feet.

    C. They have the pitter-patter of tiny feet.

    D. They never let grass grow under their feet.

    3.What should you try to avoid if you want to succeed in doing something?

    A. Having two left feet.

    B. Getting your feet wet.

    C. Getting your foot in the door.

    D. Having both feet firmly on the ground.

    4.What do we know about Sam’s new business?

    A. It’s a big success. B. It’s not started yet.

    C. It lies high in the mountains. D. It opens only in winter.

    5.What may be the best title for the passage?

    A. Use your feet properly. B. Feet help us walk and run.

    C. How to be a good dancer. D. Ready for a new business.
