I am sorry to hear that you are worried about the variety of English you have been learning.

    Firstly, the differences between British and American English may surprise those{#blank#}1{#/blank#}have learned English for years.There{#blank#}2{#/blank#}(be) almost no differences in grammar and only a few differences in vocabulary.British and American people have no difficulty{#blank#}3{#/blank#}(understand) each other.They watch films and televisions from each other's countries for{#blank#}4{#/blank#}(please).

    Secondly, there isn't only one British{#blank#}5{#/blank#}American English.For example,all major cities in the UK have{#blank#}6{#/blank#} (they) own dialects with different accents from each other.Sometimes these accents can be{#blank#}7{#/blank#}(hard) to understand for even a British person than some Americans.Also,there are Englishes from many other countries.People who speak these Englishes usually also manage{#blank#}8{#/blank#}(communicate) with other English speakers without any problems.

    All learners need to be able to understand English spoken and written by as many people as possible and they need to be able to speak English so that as many people as possible can understand them.You should concentrate on this goal,not on{#blank#}9{#/blank#}to speak “British” or “American” English.

    I hope this is{#blank#}10{#/blank#}(help).

    This weekend I was delighted to show my parents around Seville, as they {#blank#}1{#/blank#}(come) for a short but sweet visit. Although the weather wasn't the best, we still made {#blank#}2{#/blank#} best of our time together.

    Being reunited with the people you love in a new place {#blank#}3{#/blank#}(bring) excitement. Showing them around the new city makes you{#blank#}4{#/blank#} (extraordinary) happy. For example, as Seville is known for flamenco (弗拉门科舞), I took them to see a famous {#blank#}5{#/blank#}(perform) my friends recommended to me, which gave us such a wonderful visual feast. Furthermore, getting to show your visitors the places {#blank#}6{#/blank#} (appeal) to you is a pleasant feeling, because you are eager to let them know where you love to spend your time. You are letting them get involved{#blank#}7{#/blank#} your new life. Also you have the opportunity{#blank#}8{#/blank#} (show) your beloved ones the new places that they may fall in love with.

    So, after a two-day trip, I feel pleased to have had the time to explore those {#blank#}9{#/blank#}(attraction) with my parents. I am already looking forward to their next visit {#blank#}10{#/blank#}I can show them more of what Seville offers and what I am still yet to discover.

    The heat wave that broke high temperature records in five European countries a week ago is now over Greenland, {#blank#}1{#/blank#} (cause) the surface of the islands vast ice sheet to melt at near-record levels and a huge {#blank#}2{#/blank#} (lose) of ice in the Arctic. On Wednesday alone, more than 10 billion tons of ice was lost to the oceans by surface melt, which is equal {#blank#}3{#/blank#} about 4,000,000 Olympic-sized swimming pools, said Ruth Mottram, a climate scientist with the Danish Meteorological Institute.

    Melting {#blank#}4{#/blank#} (increase) in recent decades because of climate change and has been decreasing accumulation from snow. Previously, during the 1970s and the 1980s, Greenland lost {#blank#}5{#/blank#} average of 50 billion tons of ice each year. From 2010 to 2018, that figure shot up to 290 billion tons {#blank#}6{#/blank#} (annual). This summer, the extent of the melt could surpass (超过) the record set in 2012, {#blank#}7{#/blank#} about 97% of the ice sheets surface began to melt. NASA-JPL Caltech reported at the time.

Greenland, the worlds largest island, {#blank#}8{#/blank#} (lie) between the Atlantic and Arctic oceans, with 82 per cent of its surface {#blank#}9{#/blank#} (cover) in ice. A June 2019 study by scientists in the U. S. and Denmark said melting ice in Greenland alone will add between 5 and 33 centimeters to the rising {#blank#}10{#/blank#} (globe) sea levels by the year 2100. If all the ice in Greenland melted, which would take centuries, the world's oceans would rise by 7.2 meters.
