   Penguins are the number-one attraction for many visitors to Antarctica. If you go on a ship that is allowed to make shore landings, you may see them. But to get a close look at penguins, you have to be smart.

First of all, keep in mind that Antarctica’s visitor rules require that you remain at least five meters away from the penguins in order not to disturb them. You could easily become responsible for the death of a little penguin or the destruction of an egg if your too-close presence should disturb a penguin parent.

If a penguin is trying to move away from you, you must stop what you’re doing and back off even if you’re farther than five meters away. However, the rules don’t prevent a curious penguin from approaching within five meters of you — as long as the bird makes the move, not you.

Little penguins, in particular, are quite curious. I’ve seen several lucky tourists who were astonished to find that little penguins came right up to them. If a penguin comes extremely close to you, remember that you are not allowed to touch or hold it.

Here are more tips for getting close to penguins.

Ignore the smell: where penguins live is filled with guano(海鸟粪)and the smell takes some getting used to.

Be quiet because loud noises make penguins nervous. Fast or sudden movements signal meat — eating animals to penguins, and they react accordingly, so slow down when you walk around them.

Since it may take half an hour or more before the penguins get used to you, you need to be patient. Put away your camera — too often people are so focused on getting the pictures that they forget to look with their own eyes, but most of your most memorable experiences in Antarctica will be marked in your mind, not on a roll of films.

【小题1】What will happen if visitors disturb penguins according to Paragraph 2?
A.Visitors may step on a little penguin.
B.Penguin parents may break their eggs.
C.Visitors are easily attacked by penguins.
D.Penguin parents may attack other animals.
【小题2】When a penguin is trying to move away from you, you’d better ____________.
A.step backB.try to stop it
C.go after it quietlyD.keep five meters away from it
【小题3】If a penguin comes very close to you, ____________.
A.you may hold it
B.you may touch it gently
C.you should stay where you are
D.you should walk away carefully
【小题4】The author advises visitors to Antarctica to ____________.
A.ignore loud strange noises
B.take as many pictures as they can
C.allow penguins to get used to them
D.stay away from meat-eating animals

   Today, we drive safer cars on safer roads, but most car accidents are the result of human error. 【小题1】 So it’s a good idea to review some basic rules for safe driving. Here are four driving tips that will help bring you and your passengers home unharmed.

1. Practice defensive(保护的)driving.

Defensive driving includes keeping a safe distance and not speeding. 【小题2】 Accept small delays, such as staying in line behind a slower car instead of suddenly changing lanes.

2. 【小题3】

Sometimes, it doesn’t matter how safely you drive. You are driving at the speed limit and obeying all traffic rules but someone else can crash into you. One good rule is to think everyone else on the road is a fool and be prepared for anything unexpected. 【小题4】 And it pays to be ready when you do.

3. Don’t follow too closely.

Drivers need enough time to react if the car in front makes a sudden turn or stop. It can be too difficult for drivers to judge the proper distances while driving and the exact distance is adjusted by speed, so most experts suggest a “three-second rule”.

4. Be more careful in bad weather.

【小题5】 Drive below the speed limit if necessary, keep extra space between you and the car ahead, and be especially careful around curves. If the weather worsens, just find a safe place to wait out the storm.

A.Wear your safety belt.
B.Watch out for other drivers.
C.Chances are that you’ll eventually meet someone foolish.
D.The best way to reduce accidents is to practice safe driving behaviors.
E.If you’re driving through fog, heavy rain or on icy roads, be extra careful.
F.Remaining calm in the face of annoying traffic is another major part of the idea.
G.If a driver is tired enough to fall asleep while driving, the results are terrible.

   For some people, the warmest memories from childhood come from being read a great story. 【小题1】 It develops children’s language skills and increases their ability to succeed in school and, later, work.

Experts say parents should read books that are not too long and on the right age level so that children will not lose interest. They say parents should also point to and talk about pictures in books for infants (幼儿). 【小题2】

Elizabeth Lyttleton has three daughters. They are at age ten, eight and two. 【小题3】 She says, "I watch my two-year-old, who is now getting a big language explosion. So much of it comes from the books that she reads. With my eight-year-old, it’s now the broadening horizons (眼界). The oldest now truly reads for pleasure and can get lost in young adult books. "
