Do you like air travel with a service dog? Air travel makes some people very nervous. The crowds, the noise and flying itself can cause unease. But there are classes people can take to help them defeat their fear of flying. And, let me introduce similar training for service dogs that suffer the same problem

Service dogs almost never leave the side of the people they care for. You will see them working on buses, trains and other public transport systems. But the busy environment found at an airport can trouble even the best trained working dog.

    People with disabilities depend on their dogs. They want the animals to safely guide them through security areas. They also need the dogs to remain calm on duty on the plane, even when the flying is not smooth. This takes special training. The Air Hollywood K9 Flight School is one place where such help can be found.

    The school has a piece of equipment that provides the sights, sounds and even the feel of an airplane in flight. It is called a flight simulator, which was built for filming airplane scenes in movies.

    Sandy Alexander has a disability that requires his two-year-old dog, Doc, to be always at his side. Mr. Alexander took the dog to the flight school to get him ready for plane trips. He says Doc did not like the bumpy part of the flight simulation( 模拟).

    Dog trainer Mary Segall is with Canine Companions for Independence. It provides dogs for people with disabilities. Ms Segall says successful training is based on a simple rule: preparation.

    " Dogs need to be exposed gradually and repetitively to stimulation, to the environment, to loud noises, to sounds and to other dogs so that when this experience happens to them on a daily basis, they are  able to act in a way that they're used to acting and that they don't get excitable."

    Dog owners who attended the training at Air Hollywood K9 Flight School say they now feel much more at ease about future flight. Their dogs also seem ready for take-off.

    There's a new achievement in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale(大规模地). And the industry isn't stopping there.

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that—it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same", freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers(消费者) to print food with customized(定制的) nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients (烹饪原料) must be changed to a paste（糊状物）before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are limited to dry ingredients, because meat and milk products may easily go bad. Some experts are doubtful about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

    There are so many expressions in American English that sound pleasant but are not.

    “Face the music” is a good example. When someone says they have to face the music, it does not mean they are going to a musical performance or concert. To face the music means to accept the unpleasant results of an action.

    Imagine a friend asks you to take care of her beautiful red sports car. She gives you the keys and says, “Thanks so much for watching my car while I'm away. But please do not drive it. It is an extremely fast car.” But you do not listen. You want to show off and pretend the car is yours. So, you drive it around town. As bad luck would have it, you lose control of the car and drive it into a stop sign. The damage is serious. When your friend returns, you must tell her what you have done and “face the music”. That could mean losing her friendship or paying for repairs to her sports car or both. Whatever the music is, you must face it.

    There are other American expressions that mean the same as “face the music”.

    To “take your medicine” means to accept the results from something bad you have done. And if someone says, “You made your bed. Now lie in it.” He means you created a bad situation and now you will experience the results, or as we say in American spoken English, you must deal with it!

    “Pay the piper” also means the same as “face the music”. But, that expression has its own very interesting beginning. We will talk about that on another Words and Their Stories.

    Blue Planet It's latest episode focuses on how plastic is having a devastating effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.

    Though it seems now that the world couldn't possibly function without plastics, plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.

    We put all these plastics into the environment and we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.

    And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning in the same breath as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don't have to remake our planet energy system.

    This is not a problem where we don't know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose (处理) of it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag--when taken collectively, these choices really do make a difference.

    Police Officer Tidwell left the station just after 8 a.m. on Sunday June 4. He had spent a boring night on duty and was looking forward to his day of rest. By habit he took a short-cut down the path behind Dugby Hall road and after a minute or two he saw a man climbing down a drainpipe (雨水管)from an open bedroom window of Number 29. In silence, Tidwell crept into the garden. The man reached the ground and was dusting himself down when he felt his arm caught.

    "It's 8:15 on a Sunday morning," said the officer, "and this sort of thing seems an unlikely adventure at such a time. Would you mind explaining?"

The man was obviously scared but tried to keep calm. He said, "I know what you are thinking, officer, but it isn't true. This is a funny mistake."

    "It's part of my job to take an interest in unusual events. I think you've just left this house in a manner other than the customary one. That may be quite innocent, but I'd like to make sure." Tidwell took out his notebook and a pen. "Name, address and occupation and then, please, tell me your story..."

    "Charlie Crane, lorry driver, from Nottingham, 51 Breton Street. My story..."

    "Yes. What were you doing like a fly on that wall, Mr. Crane?"

    "Well, I had a breakdown yesterday and had to stay the night here. Bed and breakfast. The land-lady's name is Mrs. Fern. She gave me breakfast at seven, and I was out of he: mthe right way and down at the lorry by half past seven. Only when I felt around for a cigarette did I realize I'd left $80 in my envelope under the pillow here at number 29. I always put it under my pillow at night. It's a habit I've got into. I even do it at home...

    "I see. Why didn't you miss it when you went to pay Mrs.... What's her name?"

    "I'd paid her last night. You've got to pay when you take the room, see? So I came rushing back, but it's Sunday, and she'd gone back to bed, and could I wake her? I rang the bell and banged on the front door for ten minutes before I came round here to the back and spotted my bedroom window still open. Up I went, then, up this pipe. It's a trick I learned in the army. She didn't make the bed、and money was still there. You know the rest, I hope you believe it because... "

    "Mr. Crane, whatever are you doing here? I thought you'd gone an hour ago." It was Mrs.  Fem, speaking from the kitchen at the corner of the house.

Gemini Man

    Gemini Man is a big-budget Hollywood sci-fi-action movie based on an original concept, rather than on a superhero comic or an old TV series, even though this particular original concept is more 20 years old. In it a government assassin (杀手)is being hunted down by his own clone The original script was sold by Darren Lemke to a studio in 1997, and since then almost every male A-listener has been attached as a potential star. Now, at long last, Ang Lee has directed Gemini Man, and Will Smith plays both the veteran assassin and his much younger doppelganger (分身).

Jojo Rabbit

    During World War Two, a 10-year-old German boy (Roman Griffin David) is desperate to be a dutiful Nazi, only to discover that his mother (Scarlett Johansson) is hiding, a Jewish girl (Thomasin McKenzie) in their house. It may not sound like the stuff of a big-hearted comedy but Taika Waititi can make anything warm and funny. As well as writing and directing Jojo Rabbit, Waititi co-stars as the boy's imaginary friend,a nitwitted Adolf Hitler.

Doctor Sleep

    Mike Flanag's new film is adapted from Stephen King, novel, Doctor Sleep, which was a sequel (续集) to The Shining. You can expect to see blood flowing out of lifts in a rapid stream, ghostly twin girls and headache-including carpet patterns. Ewan McGregor stars as Danny Torrance, the boy with psychic powers m 1980 film. Now, he is a middle-aged hospital counsellor.

Maleficent: Mistress of Evil

    Here's another chance to see Angelina Jolie. In 2014 she starred in Maleficent, Disney's live-action remake of the Sleeping Beauty cartoon from 1959. The twist was that the eponymous wicked fairy wasn't so wicked, after all, and that the real villain was the father of Princess Aurora (Elle Fanning). The sequel's subtitle promises that Maleficent will actually be evil this time around, her change of heart prompted by Aurora's engagement to handsome prince (Harris Dickinson).
