The human body can tolerate only a small range of temperature, especially when the person is engaged in vigorous activity. Heat {#blank#}1{#/blank#} usually occur when large amounts of water and/or salt are lost through oversweating following exhausting exercise. When the body becomes overheated and cannot {#blank#}2{#/blank#} this overheatedness, heat exhaustion and heat stroke are possible.

    Heat exhaustion is generally {#blank#}3{#/blank#} by sweaty skin, tiredness, sickness, dizziness, plentiful sweating, and sometimes fainting, resulting from a(n) {#blank#}4{#/blank#} intake of water and the loss of fluids.  First aid treatment for this condition includes having the victim lie down, {#blank#}5{#/blank#} the feet 8 to 12 inches, applying cool, wet cloths to the skin, and giving the victim sips of salt water (1 teaspoon per glass, half a glass every 15 minutes) over a 1-hour period.

    Heat stroke is much more serious; it is a(n) {#blank#}6{#/blank#} life-threatening situation. The characteristics of heat stroke are a high body temperature (which may reach 106° F or more); a rapid pulse; hot, dry skin; and a blocked sweating {#blank#}7{#/blank#}. Victims of this condition may be unconscious, and first-aid measures should be {#blank#}8{#/blank#} at quickly cooling the body. The victim should be placed in a tub of cold water or {#blank#}9{#/blank#} sponged with cool water until his or her temperature is sufficiently lowered. Fans or air conditioners will also help with the cooling {#blank#}10{#/blank#}. Care should be taken, however, not to over-chill the victim once the temperature is below 102° F.

Titanic II Could Sail as Soon as 2022

    If you thought the long-delayed project to launch a full-size copy of the ill-fated Royal Mail Ship Titanic was sunk in the water—think again. Just like Celine Dion sang back in 1997, the travel project will "go on and on."

    Australian businessman and politician Clive Palmer, who is behind the {#blank#}1{#/blank#}, announced in September that work on the ship had started again. The idea was first floated in 2012. It is said that the new ship will be a(n) {#blank#}2{#/blank#} copy of the infamous ship, which sank in 1912 following a crash with an iceberg (冰山).

    To avoid a(n) {#blank#}3{#/blank#} disaster, Titanic II will apparently be equipped with plenty of life boats, modern navigation (导航) and radar equipment. The first voyage, however, will take passengers from Dubai to New York, reports CruiseArabia, with the first sailing {#blank#}4{#/blank#} to take place in 2022. Blue Star Line says the nine-decked ship will be home to 835 cabins, and 2,435 passengers will be {#blank#}5{#/blank#}. You'll be able to buy first-, second- and third-class tickets—just like in the original.

    Meanwhile tourists with plenty of money might soon have the chance to dive to the {#blank#}6{#/blank#} of the original Titanic. American company OceanGate has planned diving trips for 2019, costing $105,129 per person.

    Of course, the original Titanic voyage ended in {#blank#}7{#/blank#}, with over 1,500 people losing their lives. For many, voyages to the original ship are in bad taste. Steve Sims, founder of The Bluefish, said earlier in 2018 that he doesn't see diving to the original one as {#blank#}8{#/blank#}.

    Realistically, it's {#blank#}9{#/blank#} whether Titanic II will ever see the light of day—or whether the diving tours will happen soon. But one thing is for certain, more than 100 years after the Titanic's first and only voyage, global interest in this ship shows no {#blank#}10{#/blank#} of slowing down.
