Have you ever had a case{#blank#}1{#/blank#} a mistake helped you understand an idea or a skill? For me,it was sailing.I took a sailing class when I was in high school.No matter how many times I read the{#blank#}2{#/blank#} (explain),I could not understand the difference between a “tack" and a “jibe”—two methods of turning a boat—one much{#blank#}3{#/blank#} (safe) than the other. Later, one day, when I was sailing, a heavy wind{#blank#}4{#/blank#} ( blow ) up.We needed to head back, {#blank#}5{#/blank#} I mistook the “tack” for the “jibe” and pushed the boat in the wrong direction. Before I realized{#blank#}6{#/blank#} (I) mistake, it was too late. Luckily, no one{#blank#}7{#/blank#} (hurt).Only after this experience did I {#blank#}8{#/blank#} (clear) understand the sailing phrase “turning on the wind” that I {#blank#}9{#/blank#} (read) so many times in the textbook.I never confused a “jibe” with a “tack” again! Now I often share this story {#blank#}10{#/blank#} my students after they have made mistakes.I hope they can learn something from their mistakes and correct them instead of regretting all day.

    Tea is one of the most popular {#blank#}1{#/blank#}(drink) in the world. You make it by pouring hot water over the {#blank#}2{#/blank#}(dry) leaves of a tea plant. For centuries people believed that tea could cure illnesses, and they used it as medicine. Today scientists know that tea contains chemicals that prevent cells from {#blank#}3{#/blank#}(die). Most teas have caffeine in them, a substance that makes you feel more active. Some people have problems drinking tea because it can cause {#blank#}4{#/blank#}(sleep).

    The tea plant grows best in tropical and temperate places {#blank#}5{#/blank#} rain falls throughout the year. Tea plants can be grown from sea level {#blank#}6{#/blank#} about 2,000 meters above sea level, but the best quality grows in higher regions.

    Tea{#blank#}7{#/blank#}(come) from the leaves and buds of tea plants. Wild plants can be up to 9 meters high but on tea plantations they {#blank#}8{#/blank#}(cut) back to a bush of about a meter in height so that workers can pull the leaves {#blank#}9{#/blank#}(easy). It takes a plant tree to five years before it is ready for picking.

    A picker can harvest about 20 kg of tea a day. On large tea plantations the leaves are harvested by machines,{#blank#}10{#/blank#} the quality of tea is higher when the leaves are picked by hand.

    Texting while crossing the street will soon{#blank#}1{#/blank#}(ban)in Honolulu, Hawaii. From October {#blank#}2{#/blank#}, you could be fined if you step into a Honolulu street while looking at your phone. Honolulu is the first major U. S. city that passed a law,{#blank#}3{#/blank#}says, "No pedestrian shall cross a street or highway while viewing a mobile electronic device."

    The law {#blank#}4{#/blank#}(include) all electronic devices with screens: cell phones, tablets, gaming devices, digital cameras and laptop computers. The law does permit {#blank#}5{#/blank#}exception. Pedestrians may use such devices in the street to call emergency services and rescue workers, such as firefighters and police {#blank#}6{#/blank#}(officer).

    {#blank#}7{#/blank#}(hope), it will lower the number of people hit and {#blank#}8{#/blank#}(kill) by cars in the city. Pedestrian deaths in America have been increasing as the use of cell phones rises. Honolulu has {#blank#}9{#/blank#}(many) pedestrians hit in crosswalks than almost any other city in America. The number of pedestrian deaths in 2017{#blank#}10{#/blank#}(rise) to 6,000, 11% higher than in 2016.
