The way we cook is important. In many countries, the two choices are {#blank#}1{#/blank#}(nature) gas or electric ­powered stoves.

    The World Health Organization warns that millions of people {#blank#}2{#/blank#}(suffer) from indoor air pollution at present time, which results from the use of {#blank#}3{#/blank#}(danger) fuels and cook­ stoves in the home.

    WHO officials say nearly three billion people are {#blank#}4{#/blank#}(able) to use clean fuels and technologies for cooking, heating and lighting. As a result, more than seven million people die from exposure to indoor or outdoor air pollution each year. Most of the deaths are in {#blank#}5{#/blank#}(develop) countries, such as India, China and Latin American countries.

    WHO officials say opening a window or door {#blank#}6{#/blank#}(let) out the harmful air will not correct the situation. {#blank#}7{#/blank#}will only pollute the outdoors.

    Nigel Bruce, {#blank#}8{#/blank#} is a professor of Public Health at the University of Liverpool, says researchers are developing good cook­stoves and other equipment to burn fuels {#blank#}9{#/blank#} a more efficient way.

    But, this is just a start. It is urging developing countries to use {#blank#}10{#/blank#}(clean) fuels and increase access to cleaner and more modern cooking and heating appliances (用具).

    Many people agree that going to a museum is a good way of learning about ancient treasures. However, others may find {#blank#}1{#/blank#} boring to spend hours there. Therefore, how to make museums and their lifeless collections more appealing is a tough question worth {#blank#}2{#/blank#}（attach）importance to.

    Luckily, National Treasure（国家宝藏）, a TV program which{#blank#}3{#/blank#}（begin）to air on Dec, 3, 2017, shed light on ways to inspire interest in museums and their collections.

    Aiming to make ancient relics to come {#blank#}4{#/blank#}（live）, the program presents treasures through different artistic{#blank#}5{#/blank#}.（method）including dramatic performances and storytelling, {#blank#}6{#/blank#} fully interprets the history behind each cultural relic, so that audiences can not only understand how to appreciate the beauty of cultural relics, {#blank#}7{#/blank#} also know the civilization and the spiritual core of Chinese culture. In fact, such programs that promote traditional ancient relics have become popular {#blank#}8{#/blank#} recent years. For example, a 2016 documentary featuring the Forbidden City's cultural relics and their restorers, urged lots of college students {#blank#}9{#/blank#}（apply）to work as volunteers there. It is {#blank#}10{#/blank#}（universal）accepted that National Treasure has been successful in encouraging more people to visit museums by touching their hearts.

    The information I {#blank#}1{#/blank#}(collect) over the last few years leads me to believe that speed reading may be less {#blank#}2{#/blank#}(use) than most people think. The claim that you can read and comprehend over 30,000 words per minute is overstated. One researcher proved this in a study where irrelevant and illogical sentences were added to a text. The “speed readers” {#blank#}3{#/blank#} were tested didn't notice the irrelevant lines — the non-speed readers spotted them immediately.

    I've interviewed people who have attended the introductory sessions {#blank#}4{#/blank#} (offer) by some speed reading courses. {#blank#}5{#/blank#} (them) stories indicate that improper methods are sometimes used to sell the courses. Here's how: First, you're asked to read a passage from a book {#blank#}6{#/blank#} which most persons would be unfamiliar. Your reading speed and comprehension are tested during this exercise. Then, after about half {#blank#}7{#/blank#} hour of instruction, another reading test is given. But this time the reading is one most educated Americans know well — such as Huckleberry Finn. Not {#blank#}8{#/blank#} (surprising), persons attending these introductory sessions find that their “exit” speed and comprehension are better than their “entry”{#blank#}9{#/blank#} (perform).

    I'm one of the fiction readers who appreciate the beauty in good writing. Occasionally I'll read a passage or sentence over and over just {#blank#}10{#/blank#} (let) the beauty of its construction soak(参透) in. Good writing must be read carefully and thoughtfully to be fully appreciated.

    Do you ever throw away food at home? Have you ever thought about {#blank#}1{#/blank#} happens to the food that shops and supermarkets don't sell? Well, you might be shocked {#blank#}2{#/blank#} (find) out that nearly one third of the food {#blank#}3{#/blank#} (produce) by food industry gets wasted. What's more, around 800 million people in the world do not have enough food to lead {#blank#}4{#/blank#} healthy life.

    Many people in the UK are trying to do something about this imbalance and make use {#blank#}5{#/blank#} thrown-out food that is edible (可食用的). For example, there is a cafe in Leeds whose meals are created using unsold food from supermarkets, {#blank#}6{#/blank#} (include) a lot of vegetables, fruit, fish and other items. This unwanted food is turned into delicious soups that feed the hungry people of Leeds. Customers {#blank#}7{#/blank#} (simple) pay what they can afford, or help with the washing up.

    More cafes like this are being opened in other parts of the UK such as Bristol and Manchester, and it is now becoming a worldwide tendency. This is a(n) {#blank#}8{#/blank#} (amaze) project as food waste is one of the world's biggest {#blank#}9{#/blank#} (problem). Also, new law should {#blank#}10{#/blank#} (pass), so that supermarkets don't throw away so much perfectly good food!

    Wang: What's G. P.A.?

    Smith: G. P.A. stands {#blank#}1{#/blank#}the grade quality point average. Quality points are used {#blank#}2{#/blank#}(determine) the students' rank in class, academic honors, and academic warning, and probation or suspension.

    Wang: How can I list my overall undergraduate G. P.A. {#blank#}3{#/blank#}(use)3 digits?

    Smith: I think it's difficult to change your grade {#blank#}4{#/blank#} G. P.A., as our system of grading is different from {#blank#}5{#/blank#} in your country. I'd like to advise you to submit your {#blank#}6{#/blank#}(office) transcripts(文字稿)of all previous undergraduate and graduate work.

    Wang: That's a good idea. I took TOEFL last year, {#blank#}7{#/blank#} I haven't taken the GRE. What's to be done?

    Smith: The GRE may {#blank#}8{#/blank#}(require) by the particular graduate or professional program. You should go over the Table of Program carefully. What's your TOEFL{#blank#}9{#/blank#}?

    Wang: 630.

    Smith: Wonderful. In general, the graduate division requires a TOEFL score of at least 575. Those {#blank#}10{#/blank#}TOEFL scores are in the range 500­575 are admitted conditionally upon successful completion of further coursework in English as a second language.
