Lake Titicaca, a famous lake in South America, lies on the border between Bolivia and Peru. But the lives of the ancient people, who once lived around the lake and {#blank#}1{#/blank#} culture was thought to be highly developed, have long remained a secret. Recently, however, scientists {#blank#}2{#/blank#}(take) part in an exploration project at the lake have found {#blank#}3{#/blank#} 1000-year-old temple beneath the water.

    Divers from the study group have discovered a building that scientists think is the remains of a temple {#blank#}4{#/blank#}(build) by the people who once lived beside the lake. The project leaders hope to begin raising {#blank#}5{#/blank#}(value) materials from the site later this week {#blank#}6{#/blank#} bad weather forces a change in their plans.

    "The scientists have not yet had the chance to study the materials {#blank#}7{#/blank#}(careful)," said the project {#blank#}8{#/blank#}(found), John Aubi. "But some have put forward the idea that the remains date from this period because they are similar {#blank#}9{#/blank#} those found elsewhere."

    So far, they {#blank#}10{#/blank#}(make) more than 200 dives into water 30 metres deep. During these dives, they have been recording the ancient remains on film. There will be a meeting, starting later this year to review the film.

    There are {#blank#}1{#/blank#} (vary) kinds of theme parks. Some parks are famous {#blank#}2{#/blank#} having the biggest or longest roller coasters, {#blank#}3{#/blank#} for showing the famous sights and sounds of a culture. {#blank#}4{#/blank#} and whatever you like, there is a theme park for you!

    The theme park you are {#blank#}5{#/blank#} (probable) most familiar with is Disneyland. With all these attractions, no wonder {#blank#}6{#/blank#} (tour) is increasing wherever there is a Disneyland.

    Dollywood is one of {#blank#}7{#/blank#} (unique) theme parks in the world. It has one of the world's largest bald eagle {#blank#}8{#/blank#} (preserve).

    In England's Camelot Park, every area of it is {#blank#}9{#/blank#} (model) after life in the days of King Arthur and the Knights of the Round Table. There you can experience the ancient days and great {#blank#}10{#/blank#} (deed) of English knights and ladies, princes and queens.

    A material can be really special when it was named after the place where it {#blank#}1{#/blank#} (create) originally. That certainly the case {#blank#}2{#/blank#} “china”. And of all types of china, white porcelain(瓷)is among the most famous.

    Nowadays, the {#blank#}3{#/blank#} (tradition)material has taken on a modern look in the  {#blank#}4{#/blank#}(hand)of four Chinese artists in the Modern White Porcelain Exhibition. And the key word here is “modern”. One of the works {#blank#}5{#/blank#} (be) a porcelain boat. But look {#blank#}6{#/blank#} (attentive) and you'll see that the boat {#blank#}7{#/blank#} (build) with porcelain looks like a takeout box. Inside the boat is a statue of a baby. The baby stands for humans and the boat is {#blank#}8{#/blank#} supports life. It suggests we may have done some damage to {#blank#}9{#/blank#} environment and that we're treating life like fast food.

    All the four artists gave white porcelain a modem style, each in {#blank#}10{#/blank#} (they)own way. And this is what the exhibition's theme comes from. It's a dialogue between the past and the present.

    Many people living in cities see riding a bicycle as good exercise. But, a recent medical {#blank#}1{#/blank#} research warned that cyclists should think twice before cycling in the streets: it actually does more harm than good {#blank#}2{#/blank#} their bodies.

    Is cycling in cities really bad for your health? Probably yes. The main danger comes from the air around you. Breathing {#blank#}3{#/blank#} in air pollution from taxis and buses can damage blood vessels(血管).Scientists say the damage could outweigh the health benefits of cycling.

    David Newby, a British {#blank#}4{#/blank#} researcher at Edinburgh University broke the news. In his tests, 15 healthy men cycled {#blank#}5{#/blank#} on exercise bikes in a room with levels of air pollution similar to those found {#blank#}6{#/blank#} on a crowded city street. After an hour of cycling, the scientists found their blood vessels became less flexible and produced less of a protein(蛋白质){#blank#}7{#/blank#} the heart needs. The damage leads to the early stages of heart disease. What's worse, the faster a cyclist pedals (蹬车),{#blank#}8{#/blank#} more air they breathe in. So those who believe {#blank#}9{#/blank#} they are improving their fitness the most are storing up the biggest trouble for {#blank#}10{#/blank#}.
