Tide is the regular rise and fall of the ocean level caused by the movement of the sun， the earth and the moon． It is considered a promising source of green energy to produce electricity in coastal areas．
To make use of tidal energy， we need to build tidal power stations． The bays and the river mouths where the tide is high（the tidal range is more than 10 metres） are usually perfect sites to build tidal power stations． There are many such places in the world． According to the IRENA （ the International Renewable Energy Agency）， by just using 2% of our coastlines， we can produce 4，383TWh of ocean power each year， enough to meet 16.4% of the world's electricity needs．
To build a tidal power station， we need to build a dam． In the dam are many turbines and on each turbine there is an electric generator'． When the tide rises，water comes through the dam，the turbines turn and the electric generators work， producing electricity．When the tide falls，water goes out through the dam， the turbines turn again．The electric generators continue to work．
Tidal energy has its advantages．Using tidal energy to produce electricity is much cheaper than using the traditional energy， like coal or gas． For example， the Rance Tidal Power Station in France has been there for over 50 years， producing around 5.000.000TWh of electricity each year． The cost is only 1.3 cents/TWh．
Tidal energy can be used nearly 24 hours a day． As long as the sun， the earth and the moon exist，we can use it to produce electricity． But without sunshine， there is no solar energy． When there is no wind，electric generators will not work． In addition， with the development of modern technology， tidal energy can be stored and used to produce electricity continuously．
However， we still have some problems to solve． It is difficult to build a dam in the sea， and the cost is very high．Moreover it's expensive to keep a tidal power station in its best condition．Scientists are working on them．
（1）A tidal power station is best built ．
A．at a river mouth with wind
B． along the coast with waves
C． In a bay with tide high enough
D．in coastal areas with sunshine
（2）The underlined word "turbine" in Paragraph Three is a machine to ．
A． make the tide rise and fall
B． make an electric generator work
C． let water go through the dam
D．keep the dam in good condition
（3）What advantage does tidal energy have？
A． We can use it to get useful tide．
B． It can improve the ocean environment．
C． We can use it nearly all the time．
D． It meets 16． 4% of the electricity needs．
（4）How can we make better use of tidal energy？
A． By digging more bays and river mouths．
B． By building cheaper tidal power stations．
C． By closing traditional electric power plants．
D． By using tidal energy to replace other energy．

任务 1:完成表格，每空一词
On October 31 every year, children in the US will see “witches” and “ghosts” walking on the street. Is this the end of the world? No, but it is Halloween!
Halloween is exciting and popular with the people in the US and Canada. There are many colorful activities to celebrate it. One traditional, and favorite game is trick-or-treat. During the night of Halloween, children in scary clothes walk around the town. They knock on nearby houses and shout, “trick or treat!” This means “You can give us some candy, or we’ll play a trick on you!” Most people love giving sweets to children. So there are seldom any tricks. Some schools also hold Halloween parties. Sometimes, teachers are also happy to dress up and join in the party. Grown-ups may visit haunted(闹鬼的) houses. It can be very scary sometimes. But they just love following the saying “The scarier, the better.” What exciting night of scares!

任务1根据英文释义及首字母提示，拼写单词。
The Chinese and Western eating habits are different. Everyone has his or her own plate of food in the western countries. In China, we put the dishes on the table and everybody shares. It is always polite to let guests or older people at the table taste every dish first.
Although there are no strict rules on how to set chopsticks and spoons, there are some things
you should never do during a Chinese meal. Firstly, and the most importantly, we will put your chopsticks on the dish instead of putting them upright (直立的)in the rice bowl. If you stick your chopsticks in the rice bowl, it seems you want someone at the table to die. Don’t tap on your bowl with your chopsticks. Beggars tap on their bowls, so this is not polite, especially when you eat in a friend’s home.
任务2:同义句转换，每空一词。
Chopsticks will _______ ______ on the dish instead of putting them upright in the rice bowl.
任务 3:根据短文内容简答问题。

For hundreds of years, scientists have been trying to answer what things have an effect on people’s emotions(情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be affected by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, it helps our bodies produce vitamin D(维生素). Vitamin D helps our bodies make a special chemical. This special chemical affects our brains and makes us feel happy. For example, there are long, dark winters of little sunlight in some countries in the world, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial lights have been built. People can go there and get “sunlight” for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these days, the weather can affect our emotions. Sadly, while the weather can change us, we can hardly change the weather.

It was Molly’s job to hand her father his blue paper lunch bag each morning before he went to work. One morning, besides his usual lunch bag, Molly handed him a second brown paper bag. “What’s in it ?” his father asked. “Just some little things. Take it with you,” Molly answered.
At noon, he opened Molly’s bag and took out the things in it: three hair ribbons, two small stones, a plastic dinosaur, a small doll… The busy father smiled, finished eating, and swept the desk clean into the dustbin, Molly’s bag was together with. That evening, Molly ran up behind him as he was reading the paper. “Where’s my bag?” “I left it at the office. Why?” “I forgot to put this note in it, ” she said. “And, besides, Daddy, the things in the bag are the things I really like— I thought you might like to play with them in your free time. You didn’t lose the bag, did you, Daddy?” “Oh, no,” he said, lying. “I just forgot to bring it home.”
While Molly hugged her father’s neck, he opened the note that read: “I love you, Daddy.” Molly had given him her treasures(财富)— all that a 7-year-old girl had. Love in a paper bag, and he missed it—not only missed it, but had thrown it in the dustbin. So he went back to the office, got the bag back and carried it home.
Sometimes we can think of all the happy time in our sweet life, We should all remember that it’s not the destination(终点) that is important in life, but the journey. That journey with the people we love is all that really matters. It is such a simple truth but it is so easily forgotten.
