8. I WANDERED LONELY AS A CLOUDBy William WordsworthI wandered lonely as a cloudThat floats on high o'er vales and hills,When all at once I saw a crowd,A host, of golden daffodils;Beside the lake, beneath the trees,Fluttering and dancing in the breeze.Continuous as the stars that shineAnd twinkle on the milky way,They stretched in never-ending lineAlong the margin of a bay:Ten thousand saw I at a glance,Tossing their heads in sprightly dance.The waves beside them danced; but theyOut-did the sparkling waves in glee:A poet could not but be gay,In such a jocund company:I gazed—and gazed—but little thoughtWhat wealth the show to me had brought:For oft, when on my couch I lieIn vacant or in pensive mood,They flash upon that inward eyeWhich is the bliss of solitude;And then my heart with pleasure fills,And dances with the daffodils.Answer the questions based on the poem above.1.How many verses does this poem consist of? . . . .2.Dos the poem have rhymes? . . . . 3.The figure of speech that you find in the line “I wandered lonely as a cloud” is a . . . .Why? ……………………4.There are two similes in the poem.

Aku merasa kesepian

Oleh William Wordsworth

Aku merasa kesepian

Yang mengambang di atas lembah dan bukit,

Ketika semua sekaligus aku melihat kerumunan,

Kumpulan bunga bakung emas;

Di samping danau, di bawah pohon,

Berkibar dan menari tertiup angin.

Terus menerus seperti bintang-bintang yang bersinar

Dan twinkle di bimasakti,

Mereka berbaring tak berujung

Sepanjang tepi teluk:

Sepuluh ribu aku melihatnya sekilas,

Melemparkan kepala mereka dalam tarian riang.

Ombak di samping mereka menari; Tapi mereka

Overdid gelombang berkilauan di glee:

Seorang penyair tidak bisa tapi menjadi gay,

Dengan rombongan joki:

Aku hanya … dan … tapi sedikit berpikir

Apa kekayaan menunjukkan kepada saya telah membawa:

Untuk sering, ketika di sofa saya aku berbaring

Dalam suasana hati yang hampa atau termenung,

Mereka berkedip pada mata batin

Yang merupakan kebahagiaan kesendirian;

Dan kemudian hati saya dengan kesenangan,

Dan tarian dengan daffodils.

13. Tolong terjemahin Achieving the high quality of implementation needed to be successful with such measures requires an unusual an unprecedented speed of secision making by top leaders, operational thoroughness by public health systems, and engagement of society. 20 given the damage that can be caused by uncontrolled, community level transmission of this virus, such an approach is warranted to save lives and to gain the weeks and months needed for the testing of therapeutics and vaccine development. Furthermore, as the majority of new cases outside of china are currently occurring in high and middleincome countries, a rigorous commitment to slowing transmission in such settings whit non pharmaceutical measures is vital to achieving a second line of defence to protect low income countries that have weaker health systems and coping capasities. The time that can be gained thorough the full application of these measures even if just days or weeks can be invaluable in ultimately reducing covid-19 illnes and deaths. This is apparent in the huge increase in knowledge, approaches and even tools that has taken place in just the 7 weeks since this virus was discovered thorough the rapid scientific work that has been done in china​


Untuk mencapai kualitas tinggi dari implementasi yang dibutuhkan untuk menjadi sukses dengan langkah-langkah seperti itu membutuhkan kecepatan yang luar biasa dari pembuatan keputusan oleh para pemimpin puncak, ketelitian operasional oleh sistem kesehatan masyarakat, dan keterlibatan masyarakat. 20 mengingat kerusakan yang dapat disebabkan oleh penularan virus tingkat komunitas yang tidak terkendali, pendekatan semacam itu dijamin untuk menyelamatkan nyawa dan untuk mendapatkan minggu dan bulan yang dibutuhkan untuk pengujian terapi dan pengembangan vaksin. Selain itu, karena sebagian besar kasus baru di luar Cina saat ini terjadi di negara-negara berpenghasilan tinggi dan menengah, komitmen yang ketat untuk memperlambat transmisi dalam pengaturan semacam itu, baik langkah-langkah nonfarmasi sangat penting untuk mencapai garis pertahanan kedua untuk melindungi negara-negara berpenghasilan rendah yang lebih lemah sistem kesehatan dan kapasitas penanggulangan. Waktu yang dapat diperoleh melalui penerapan penuh dari langkah-langkah ini bahkan jika hanya berhari-hari atau berminggu-minggu dapat sangat berharga dalam mengurangi jumlah kematian dan kematian.

14. Acid rain can severely damage both plant and animal life. Certain lakes, for example,have lost all fish and plant life because of acid rain. Acid rain comes from sulfur in coal and oil.When they burn, they make sulfur dioxide (S02 ). Most sulfur leaves factory chimneys as thegaseous sulfur dioxide (SO2 ) and most nitrogen are also emitted as one of the nitrogen oxides(NO or NO2), both of which are gasses. The gasses may be dry deposited absorbed directly bythe land, by lakes or by the surface vegetation. If they are in the atmosphere at any time, thegasses will oxidize (gain an oxygen atom) and go into solution as acids. Sulphuric acid (H2 SO4) and the nitrogen oxides will become nitric acid (HNO3 ). The acids usually dissolve in clouddroplets and may travel great distances before being precipitated as acid rain. Catalysts such ashydrogen peroxide, ozone, and ammonium help promote the formation of acids in clouds. Moreammonium (NH4 ) can be formed when some of the acids are partially neutralized by airborneammonia (NH3). Acidification increases with the number of active hydrogen (H+) ionsdissolved in acid. Hydrocarbons emitted by, for example, car exhausts will react in sunlight withnitrogen oxides to produce ozone. Although it is invaluable in the atmosphere, low-level ozonecauses respiratory problems and also hastens the formation of acid rain. When acid rain falls onthe ground it dissolves and liberates heavy metals and aluminum (Al). When it is washed intolakes, aluminum irritates the outer surfaces of ma
