How do actors and actresses memorize hundreds of lines? Memorizing lines takes practice and constant repetition. However, there are a few ways to make the memorization process run smoothly and quickly.   

{#blank#}1{#/blank#}

    For most performers, there is no quicker way of memorizing lines. To learn lines, an actor must recite the play loud over and over again. Most rehearsals(彩排) encourage this by running through the lines or having a ＂read through＂. By the time opening night arrives, most actors have spoken their lines hundreds of times.

Listen to your cast members.

    Sometimes inexperienced actors spend rehearsals looking at fellow performers, waiting patiently to say their next line. {#blank#}2{#/blank#} This will help the actor learn his lines better because the context of the dialogue is absorbed.

    Because there is often not enough rehearsal time, many performers find ways to listen to the play's dialogue during everyday activities. They use a tape recorder or an MP3 player to listen to the lines from each relevant scene. Some actors prefer to record the lines of all the characters, including their own. {#blank#}4{#/blank#}  Others like recording the lines of fellow cast members, and they leave a blank space so that they can insert their dialogue while listening to the recording.

Think positively and don't panic.

    Most actors will experience stage fright before the opening night. Actors forget lines now and then. When it happens, however, most of the time the audience never notice. If you forget a line in the middle of your performance, don't freeze. Stay in character. Keep the scene going to the best of your ability. If unfortunately you forget a line once, you will probably never forget that line ever again. {#blank#}5{#/blank#}

A. Record your lines.

B. Practice makes perfect.

C. Read lines loud and repeat them.

D. Read lines loud and remember them in a short time.

E. Sometimes embarrassment is the toughest method of memorization.

F. Then, they not only listen carefully, but they also speak all of the lines.

G. Instead, they should be listening carefully, responding in character at all times.

    For teenagers, it's great fun to explore new places and it feels like an adventure, even when you know you're not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.

    ◆Do the map reading if you're being driven somewhere. It'll be easier if you keep the map following the direction you are traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat.

    ◆Get a group of friends together and go exploring. You'll need a good map, a compass, a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies. Tell someone where you're going before you set out and let them know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

    ◆See if your school or a club organizes orienteering(越野识途比赛) activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B(and B to C, etc. ) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compass and gain some special skills. In some way, it's not only good fun, but also a great way to keep fit.

    Do you often dream at night? How do you feel when you dream? Is it useful to our health? “Dreams may be more important than sleep, and we all need to dream,” some scientists say.

    Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in colour. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer. Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.

    Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear quickly from memory.

    Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is at work when we dream. That is why we may have a long sleep and still wake up tired.

    Green tree ants are important builders in the rainforest. They're like the worker bees of the ant world. The native forest of Thala Beach Nature Reserve is the natural home of these insects.

    They climb all over the tree that contains their nest and protect it from enemies with great fierceness. The ants are often in the fruiting trees of Tropical North Queensland. When an animal tries to help themselves to some tasty fruit, they find themselves attacked by a powerful, frightening army of green tree ants! Their bite is not very painful but many ants attacking at the same time can be extremely uncomfortable.

    The nests are large and constructed by sticking the leaves at the end of branches together to create a home looking roughly like a globe. Most of the nest construction and weaving is conducted at night. A mature colony of green tree ants can hold as many as 100,000 to 500,000 workers and may include as many as 12 trees and contain as any as 150 nests. Green tree ant colonies have one queen and a colony can live up to eight years.

    However, the ants are so busy that they fail to spot a dishonest figure. There is a spider called the Salticid spider, or the jumping spider, as they are sometimes referred to, which has excellent eyesight and is only active during daylight, weaving a protective covering of silk to spend the night in. Interestingly, the Salticid spider does not look like a green tree ant. Instead, it chemically copies green tree ants' smell. Effectively pretending to be an ant, it goes into the green tree ants' nest, enters the nursery and feasts on their babies. Green tree ants don't have good eyesight and smell everything with their antennae (two long thin parts on an ant's head). Therefore, the ants think the spider is another ant and ignore its presence within the nest.

    Next time, as you wander around Thala's native forest, keep an eye out for these busy little creatures. Look up into the trees and you'll likely spot their nests.

    In recent years, much of the sea ice that polar bears use as a hunting platform for seal meals has melted, forcing some bears — particularly young males — farther north or onto land, where they are not as skilled at hunting. When stuck on land for months, a polar bear typically is forced to survive on its own fat reserves.

    The bears were listed earlier this year as a threatened species under the U. S. Endangered Species Act as populations have declined. Meanwhile, snow geese are booming near the western Hudson Bay, and there are in fact too many of them. Their eggs can be a good food source. The geese nest on tundra (冻原；苔原) that some bears have retreated to.

    "Over 40 years, six subadult (接近成年的) male bears were seen among snow goose nests, and four of them were sighted after the year 2000," says Robert Rockwell. "I've seen a subadult male eat goose eggs whole or press its nose against the shell, break it, and eat the contents."

    Ice is melting, on average, 0.72 days earlier each year in the region studied. Snow geese are hatching eggs about 0.16 days sooner each year, according to Rockwell and his graduate student Linda Gormezano. Current trends indicate that the arrival of polar bears will correspond to the average hatching period in 3.6 years, and egg consumption could become a viable option, which the researcher concluded in a statement released today.

    A polar bear, the largest land carnivore (食肉动物), would need to consume the eggs of 43 nests to replace the energy gained from the average day of hunting seals, but Rockwell and his colleagues figure that while many polar bears may starve in coming years, the resourceful animals just might survive disappearance.

    Polar bears survived a warm period about 125,000 years ago, when sea level was 12 to 18 feet higher than it is now and trees lived above the Arctic Circle, the scientists point out.  "They've been through the warm period before，" Rockwell said.

    The polar bears' potential movement to a diet of more eggs brought to mind a quote by Ilkoo Angutikjuak, an Inuit who lives in the Canadian province of Nunavut, in the February 2008 issue of Natural History magazine, Rockwell said. Angutikjuak said: "The animals will adapt. I've heard that because they depend on sea ice, polar bears will disappear, but I don't believe it. They are very adaptable. As the sea ice changes, polar bears might get skinnier and some might die, but I don't think they will disappear."

My 13-year-old daughter sent a postcard to us while we were still away on our most recent trip to California. It 1 our house about a week later. The touching 2 nearly brought me to tears.

"Even though we 3 have two days of adventures ahead of us, I am just so 4 for everything we have experienced together on this trip," she writes.

Our youngest daughter is just about to 5 11 years old. In those years, we have never taken a true 6 as a family of four to a place we've never been. Like most 7 , I have no idea where the time has gone. But I also think these are some of the best ages to 8 with kids.

This vacation to California was our very first 9 , long-distance trip together. The kids helped 10 the trip with input on things they might like to see and do. They reached for our hands in crowds. I can't remember the last time they held our hands 11 .

One of our family bonding moments came when we took a family surfing lesson. It was the first time any of us had tried surfing, although it was something the girls had been 12 . The smiles on the girls' faces were everything. They were so 13 when they stood up on the board and rode the waves one by one.

Those are memories I'm going to 14 . And yes, I will remind them of these times the next time I reach for their 15 .
