There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community（医学界）{#blank#}1{#/blank#}a method of fighting heart disease, has had some unintended side{#blank#}2{#/blank#}(effect) such as overweight and heart disease—the very thing the medical community was trying to fight.

    Fat and salt are very important parts of a diet. They are required{#blank#}3{#/blank#}(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt{#blank#}4{#/blank#}(remove) from food, the food tastes as if is missing something. As {#blank#}5{#/blank#} result, people will eat more food to try to make up for that something missing. Even {#blank#}6{#/blank#} (bad),  the amount of fast food that people eat goes up. Fast food {#blank#}7{#/blank#}  (be) full of fat and salt; by {#blank#}8{#/blank#} (eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be {#blank#}9{#/blank#} (care) not to go to extremes. Like anything, it is possible to have too much of both, {#blank#}10{#/blank#} is not good for the health.

    Music is in the comers of everyday life. It is said to be {#blank#}1{#/blank#}(benefit) to us both physically and mentally.

    There are many ways to make music. For example, if you blow into bamboos or shells, {#blank#}2{#/blank#}(permit) air to come in, they can produce pleasant music. A recent discovery suggests that music is played much earlier than we think. In 1995, deep in {#blank#}3{#/blank#}cave in Slovenia occupied 45,000 years ago by Neanderthals, a leg bone of a bear with four finger holes was found, {#blank#}4{#/blank#} suggested that flutes（笛子）had come into {#blank#}5{#/blank#}(exist) at that time. Later, many other {#blank#}6{#/blank#}(tradition) musical instruments like drums were unearthed. Ancient people even {#blank#}7{#/blank#}(seek) a way to make music out of a bow that {#blank#}8{#/blank#}(intend) for hunting, so we have to admit that they did have a great gift {#blank#}9{#/blank#}music. But if accurately dated, the Neanderthal flute is by far the {#blank#}10{#/blank#}(early) known example of music.

    Now music can be found in every known culture, and even the most isolated（孤立的）groups have a certain form of music.

    The first UN Chinese Language Day {#blank#}1{#/blank#} (observe) on Friday at UN Headquarters in New  York in 2010. {#blank#}2{#/blank#} the world's most widely spoken language, it seems appropriate that Mandarin (普通话) has one day every year dedicated (把…专用于) to it. This {#blank#}3{#/blank#} (official) marked day of Mandarin language celebration was set by the United Nations as a way of celebrating the language's history and {#blank#}4{#/blank#} (contribute) to the world. It is hoped that having one day every year {#blank#}5{#/blank#} (celebrate) Mandarin will encourage more people around the world to take it up. With China likely to become the {#blank#}6{#/blank#} (large) economy in the world, it is important that the wider world becomes interestingly more perfect in this wonderful language. Every year UN Chinese Language Day {#blank#}7{#/blank#} ( fall) on April 20. A great way to get {#blank#}8{#/blank#} (involve) in the celebration is to join a Mandarin class or attend one of the many Confucius Institutes (孔子学院){#blank#}9{#/blank#} are set up in countries around the world. The number of people learning Chinese is on {#blank#}10{#/blank#} increase in China's neighboring countries, such as Korea, Japan, and Vietnam.

    You see them everywhere: people walking with their attention {#blank#}1{#/blank#}（concentrate）on their smartphone screens on busy streets. But walking and texting can be dangerous and cities in the United States and Europe have stepped {#blank#}2{#/blank#} their efforts to deal with it.

    In Honolulu, using the phones while crossing the street is forbidden. It has passed a law that says “No pedestrian （行人） shall cross a street or highway while viewing a mobile electronic device. In other words, do not look at a screen when you cross the street{#blank#}3{#/blank#} you could be fined. Honolulu is the first major U.S. city{#blank#}4{#/blank#} （forbid）what is called “distracted walking”.

    People {#blank#}5{#/blank#} text while walking are nearly four times as likely to have at least one dangerous action. A lot of people do it {#blank#}6{#/blank#} they know it is dangerous. They tell themselves that it is important.

    Using phones while walking may lead to injuries and deaths, but it seems to be a global problem. Pedestrian deaths {#blank#}7{#/blank#}（increase）as the use of cell phones rises in the past 5 years, and it is expected that the tendency will continue.

    Other cities have come up with creative ways to help protect those using cellphones while walking. A small town near Amsterdam has set up special crosswalks with flashing lights on the ground. When the traffic lights turn red or green,{#blank#}8{#/blank#} do the lights on the ground, reminding pedestrians when it's safe to cross. In a town of Germany, similar lights were used after a teenager using her smart phone was hit and seriously{#blank#}9{#/blank#}（injure）.

    If you still want to text while walking you could avoid being fined in Honolulu {#blank#}10{#/blank#}using voice-controlled digital assistant（数字助手） like Siri or Google Assistant Or you could just wait until you are again, safely off the street.

    Beijing's {#blank#}1{#/blank#} (forbid)City—traditionally off-limits at night for anyone except emperors—was lit up with lanterns after dark Tuesday as China {#blank#}2{#/blank#} (celebrate)the end of the Lunar New Year holiday.

    The palace complex, home to Chinese emperors for five centuries, {#blank#}3{#/blank#} (usual)closes by 5 p.m. though some distinguished guests have been taken {#blank#}4{#/blank#} after dark on occasion. It was opened at night for the first time since its rebirth as the Palace Museum 94 years ago.

    The palace walls were brightened with red Chinese lanterns—designed to recreate the {#blank#}5{#/blank#}(feel)of the royal court of old—and {#blank#}6{#/blank#} light show lit up the complex while the China National Traditional Orchestra and the Peking Opera performed. An image of a treasured picture called “A Thousand Li of Rivers and Mountains” was beamed onto the palace roof.

    People rushed to get free {#blank#}7{#/blank#} (ticket)online, for the rare night-time opening, {#blank#}8{#/blank#} were snapped up within minutes.

    “Creativity makes the 600-year-old palace younger and draws traditional culture{#blank#}9{#/blank#}(close)to the public, ”said the People's Daily. The Palace Museum is now on a campaign {#blank#}10{#/blank#}(attract)even more visitors.
