Science is always advancing over time. A self-driving car from the Google may be coming to a street near you. However, you won't be able to buy it now. “We're working to build the world's most experienced driver,” Kraft, director of the project, said. “Everything that we learn in one of our cars gets passed to all of our cars. But you may need to get over the idea of traditional car ownership along the way.”

    Google's software has already driven 5 million miles in U.S. cities, including an “early rider” test in Phoenix last April. Since then Google has grown confident enough to remove the “auxiliary wheel”: a human “safety driver”. Powering the vehicle's self-driving functions is a series of cameras, radars and sensors on the car's roof, which detect everything nearby from other vehicles and passers-by to cyclists.

    Kraft stressed that Google's cars aren't connected—they don't need a 5G wireless link to go anywhere. “The car has everything it needs to drive on the car itself.” He said, “There are no signals coming from outer space or something telling it to turn right.” The resulting ride may not be too exciting but safe. Kraft added. “We can see three football fields down the road, we would come to a stop before we ran into these crowds.”

    Google's system has a major advantage over the semi-autonomous（半自主的）systems of Tesla and Cadillac, both of which need continued human attention. Kraft said Google plans to have service in every major city by 2028 with thousands of cars driving themselves.

    You can tell a lot about a country by what's on its television sets. Britain's TV screens are completely steeped in class, and have long been so.

    From laughing at poor people in reality shows to laughing at posh people in Downton Abbey, this is how Britain likes to unwind in the evening: by laughing at other classes, and laughing at people for laughing about class.

    Like it or loathe it, many see the class system as a quite essential element of British life, together with our obsession for tea and cake and talking about the weather.

    Whether you are a lord, a lady, or just the king of your own middle class kingdom, everyone in the UK fits into the class system. How the class system works is a hard question even for a British person to answer.

    There are four main groups in the British class system: lower, working, middle and upper class. Although recently the BBC has tried to confuse everyone even more by adding three more categories.

    The British are very aware of class; it is often said that we have an in-built 'class radar'; we pick up on subtle social clues which indicate which class a person comes from. Class is not just about your job, where you live and how much you earn. It's about who you are.

    Public Health England (PHE) is targeting pizzas, ready meals, ready meat and takeaways. The government has also required the food industry to start using healthier food and encourage the public to opt for lower calorie foods.

    It is all part of an effort to cut calorie (卡路里) intake by 20% by 2024. The target will point to 13 different food groups, which are equal to about a fifth of the calorie taken by children. If action is not taken, PHE said, it would be prepared to ask the government to pass laws.

    PHE would be strictly monitoring progress by looking at which products people were buying and would be prepared to punish companies which do not take their duties. The government is also organizing a program encouraging adults to consume (消耗) 400 calories at breakfast and 600 each at lunch and dinner.

    At present, adults consume between 200 and 300 calories more than they should each day. PHE chief nutritionist Dr Alison Redstone said the 400-600-600 tip would make it easier for "people to make healthier choices" by being able to judge what they should be eating in each sitting.

    How many calories should we eat? It is suggested that women eat no more than 2,000 calories a day, while men should limit their intake to 2,500. For children, it depends on age. A four-year-old should consume no more than 1,300, while for teens aged 17 and 18, it is about 3,000, but overweight children are eating up to 500 calories more than that.

    Prof Russell Viner, of the Royal College of Pediatrics and Child Health, said it was a necessary move. He said, "Over the past 40 years, there had been a slow growth in food sizes, with pizzas and hamburgers simply much bigger than they were in our parents' time." The convenience of fast food at pocket money prices and the advertisement of unhealthy food and drinks to children add to the problem.

    Have you ever been to London? Here is some hotel information for you.

    While small may be beautiful, tall is just plain uncomfortable it seems, particularly when it comes to staying in hotels and eating in restaurants.

    The Tall Persons Club Great Britain (TPCGB), which was formed six months ago to campaign for the needs of the tall, has turned its attention to hotels and restaurants. Beds that are too small, shower heads that are too low, and restaurant tables with hardly any leg-room all make life difficult for those of above average height, it says.

    But it is not just the extra-tall whose needs are not being met. The average height of the population has been increasing yet the standard size of beds, doorways, and chairs has remained unchanged.

    "The bedding industry says a bed should be six inches larger than the person using it, so even a king-size bed at 6′6″ (6 feet and 6 inches) is falling short for 25% of men, while the standard 6′3″ bed caters for less than half of the male population." Said TPCGB president Phil Heinricy, "seven-foot beds would work fine."

    Similarly, restaurant tables can cause no end of problems. Small tables, which mean the long-legged have to sit a foot or so away from them, are enough to make tall customers go elsewhere.

    Some have already taken note, however. At Queens Moat Houses′ Caledoman Hotel in Edinburgh, 6′6″ beds are now put in as standard after requests for longer beds from taller visitors, particularly Americans.
