Read This Poem by Langston Hughes.

Theme for English B
BY LANGSTON HUGHES
The instructor said,

Go home and write
a page tonight.
And let that page come out of you—
Then, it will be true.

I wonder if it’s that simple?
I am twenty-two, colored, born in Winston-Salem.
I went to school there, then Durham, then here
to this college on the hill above Harlem.
I am the only colored student in my class.
The steps from the hill lead down into Harlem,
through a park, then I cross St. Nicholas,
Eighth Avenue, Seventh, and I come to the Y,
the Harlem Branch Y, where I take the elevator
up to my room, sit down, and write this page:

It’s not easy to know what is true for you or me
at twenty-two, my age. But I guess I’m what
I feel and see and hear, Harlem, I hear you.
hear you, hear me—we two—you, me, talk on this page.
(I hear New York, too.) Me—who?

Well, I like to eat, sleep, drink, and be in love.
I like to work, read, learn, and understand life.
I like a pipe for a Christmas present,
or records—Bessie, bop, or Bach.
I guess being colored doesn’t make me not like
the same things other folks like who are other races.
So will my page be colored that I write?
Being me, it will not be white.
But it will be
a part of you, instructor.
You are white—
yet a part of me, as I am a part of you.
That’s American.
Sometimes perhaps you don’t want to be a part of me.
Nor do I often want to be a part of you.
But we are, that’s true!
As I learn from you,
I guess you learn from me—
although you’re older—and white—
and somewhat more free.

What inferences did you make while reading ''Theme for English B'' ?

Answers

Answer:

Theme for English B”, As a Representative of Self: This poem is about the speaker’s attitude, interests, and background. The professor asks the narrator to write a page about himself. The speaker begins his assignment, providing some necessary autobiographical details because he wants true. After talking about his age, academic history and identity, he unveils a crucial reality that he is the only colored student in his class. He believes people belonging to different casts, color and identities share common interests. Also, he writes that his assignment will not fully represent him. Willingly or unwillingly, they both influence each other. In this way, all of his doubts, questions, and hesitations become his page for English B.

Major Themes in “Theme for English B”: Identity, creativity, and racism are major themes of this poem. Right from the beginning, the black speaker struggles to come up to the expectations of his white professor. Although there is a divide between the speaker and his professor, yet he writes about his experiences and likes to present his true character in his assignment. At first, he is a bit nervous as he feels indifferent. However, he realizes that his likes and interests are similar to the people belonging to other races, which makes him confident. The speaker establishes a ground reality that America is a land of diversity and people influence each other regardless of their identities and skin color.

Read the excerpt from Team Moon.

The trouble with option 2 was that the venting might push the fuel to an unstable condition. Or, another possible outcome of the “burping”: what if the landing gear hadn’t deployed correctly? Could any movement, or any resulting burst—no matter how small—tip the LM over? Many a voice in the debate thought the safest option was to abort—now! But that opinion was quickly overruled by the Grumman and NASA leadership (who were confident of the landing gear), and the consensus of the leaders was that it would be safe to gently, gently burp the engine.

Why does the author use a problem-solution text structure in the paragraph?

to help the reader understand the astronauts’ feelings about the landing
to help the reader understand the intense pressure of the situation
to help the reader understand the similarities between the leaders’ options
to help the reader understand the process of “burping” an engine

Golden Days

by Lizzie Lawson

There are days of summer sunshine,
Of warm and sunny weather,
When the hedge is full of hawthorn
And hills are glad with heather.

There are days of silent sadness,
Of frost, and snow, and rain,
When we fear that summer's gladness
Will never come again.

And now our songs are minor key,
And now in merry tune;
The windward side will change to lee,
And January to June.

Day and night the sun is shining,
Though he may hide his head;
Each cloud has a silver lining,
The flowers are asleep not dead.

Every day may have its playtime
Made bright by cheerful lays;
And life be one long Maytime,
A year of golden days.

Read the theme.

Life, like nature, has pleasant and unpleasant moments.

How does this theme develop over the course of "Golden Days"?


Happiness is like the warmth of summer, and sadness is like the coldness of winter.

The playtime of spring helps people feel alive and excited again after a long winter.

The seasons are all rewarding and pleasant in their own unique ways.

Nature and life are both unpredictable, especially during winter and summer months.

Answers

Answer:

Life is unpredictable in terms of whats gonna happen next , time is rewarding and in a keen way sad because it can be spent but not bought back . I feel like the theme of this poem is to not underestimate a days worth , in terms of some seasons feeling gloomy when others are full of happiness spend your time accordingly so you can make the most of it.

Explanation:

I hope I was able to answer your question , thank you and have a great day :)

Time is rewarding and in a sharp way sad because it can be spent but not recovered, and life is unpredictable in terms of what will happen next. The poem's main message, in my opinion,

What is an opinion?

An opinion may be expressed regarding subjective issues for which there is no definitive evidence or it may be expressed regarding facts that are being contested on the pretext that everyone has the right to their own ideas.

Is not to undervalue a day's worth of opportunities. Given that some seasons can be depressing while others are joyful, you should plan how you will spend your time so that you can get the most out of it.

Therefore, opinion is preferable to being unpleasant without cause, especially

Plant and animal cells have many of the same parts. Every cell has a(n)  cell membrane  that helps it keep its shape. Most cells have an nucleus that contains the organism’s genetic information. Between these two cell parts both plant and animal cell contain a gel-like substance called cytoplasm. Both plants and animals use a process called cellular respiration to convert food to energy. The rod-shaped structures that help carry out this process are mitochondria. Both plant and animal cells contain saclike storage structures called vaculoes. Because plants make their own food in a process called photosynthesis, their cells have some structures that animal cells do not have. The pigment that makes some plants green is called chlorophyll. The membranes in plant cells are surrounded by cell wall. Animal cells do not have these structures.

adapted from To My Old Master

This letter was written by Jourdon Anderson, a person who escaped slavery during the Civil War. The letter is addressed to the man who once held him in slavery, Colonel P.H. Anderson. After the Civil War, Colonel Anderson’s plantation was failing, and he wrote Jourdon to ask him to return to work the fields and help him save his business.

Dayton, Ohio, August 7, 1865.

To my old Master, Colonel P. H. Anderson, Big Spring, Tennessee.

Sir:

I got your letter, and was glad to find that you had not forgotten Jourdon, and that you wanted me to come back and live with you again, promising to do better for me than anybody else can. I have often felt uneasy about you. Although you shot at me twice before I left you, I did not want to hear of your being hurt and am glad you are still living. I would have gone back to see you all when I was working in the Nashville Hospital, but one of the neighbors told me that Henry intended to shoot me if he ever got a chance . . .

I want to know particularly what the good chance is you propose to give me. I am doing tolerably well here. I get $25 a month, with victuals and clothing; have a comfortable home for Mandy (the folks call her Mrs. Anderson), and the children, Milly, Jane, and Grundy, go to school and are learning well . . .

As to my freedom, which you say I can have, there is nothing to be gained on that score, as I got my free papers in 1864 from the Provost-Marshal-General of the Department of Nashville. Mandy says she would be afraid to go back without some proof that you were disposed to treat us justly and kindly; and we have concluded to test your sincerity by asking you to send us our wages for the time we served you. This will make us forget and forgive old scores and rely on your justice and friendship in the future. I served you faithfully for thirty-two years, and Mandy twenty years. At $25 a month for me, and $2 a week for Mandy, our earnings would amount to $11,680. Add to this the interest for the time our wages have been kept back, and deduct what you paid for our clothing, and three doctor’s visits to me, and pulling a tooth for Mandy, and the balance will show what we are in justice entitled to.

From your old servant,

Jourdon Anderson

P.S.— Say howdy to George Carter and thank him for taking the pistol from you when you were shooting at me.
In "To My Old Master," which quote from the text best states a claim Jourdon makes about the value of the Colonel's offer of independence and a better life?

"I have often felt uneasy about you. Although you shot at me twice before I left you, I did not want to hear of your being hurt and am glad you are still living."

"As to my freedom, which you say I can have, there is nothing to be gained on that score, as I got my free papers in 1864 from the Provost-Marshal-General of the Department of Nashville."

"I get $25 a month, with victuals and clothing; have a comfortable home for Mandy (the folks call her Mrs. Anderson), and the children"

"Mandy says she would be afraid to go back without some proof that you were disposed to treat us justly and kindly; and we have concluded to test your sincerity by asking you to send us our wages for the time we served you."

It might not be well known, but there is a desert in North America. It spans along the western side of the continent, from southern Oregon to northern Mexico. It is mostly contained in the arid area between the Rocky Mountains to the east and the fertile coast of the Pacific Ocean to the west. Researchers estimate that the desert is between 500,000 and 730,000 square miles.

Differences of latitude, elevation, climate, topography, vegetation, soil, and human use have divided the desert into a cold region and a hot region. The cold region of the desert is known as the Great Basin Desert. This area covers almost all of Nevada, western Utah, and sections of the neighboring states. South of this basin is the Mojave Desert, which is the hot region of the North American Desert. This area covers much of California, southern Nevada, and some of Mexico.

As a desert, the area is arid because of high evaporation, extreme temperatures, high winds, localized storms, and sun-beaten land. Life in the desert is a struggle for humans. People do live in this desert, but the pockets of people are dispersed and isolated. Native Americans and European settlers have added to the population of the region. Despite the harsh conditions, a surprising number of plants, animals, and reptiles make the desert their home. In fact, some species can only be found in the desert.

What evidence does the author use to support the idea that there are people who live in the desert?

A. This area covers almost all of Nevada, western Utah, and sections of the neighboring states.
B. Native Americans and European settlers have added to the population of the region.
