Nonfiction Reading Response #3

    In, “DDT Linked to High Blood Pressure in Women” by Lindsey Konkel and Environmental Heath News, women that are exposing to DDT when pregnant has a risk of high blood pressure later on in life. DDT is a commonly used insecticide; it is also a form of chemical. Even though DDT was banned in the U.S since 1972, it is still used in Africa as a “combat to malaria infected mosquitoes.” Research shows that women who are exposed to these chemicals could potentially develop high blood pressure later on.

 Exposure to DDT is very dangerous for pregnant women. “DDT interferes with hormones and it has been linked to decreased fertility, preterm delivery and diabetes” (Konkel and Environmental Health News 1). Since during pregnancy, whatever the mom is exposing to, the children does too, through the placenta. This can directly harm the growing fetus inside the womb. Statistics show that out of 111 children whose had been exposing to DDT, 21% had hypertension. Hypertension is caused by DDT and it might also lead to stroke and heart diseases. DDT is very dangerous for pregnant women.

       DDT also causes high blood pressure in women. It specifically targets the area in the body where the blood pressure is kept in control. Studies show that “pesticide applicators with high blood pressure had higher DDT exposures than those with healthy blood pressure” (Konkel and Environmental Health News 1). Approximately 2/3 of the people exposing to DDT had 2.5 to 3.6 times more likely to have high blood pressure before the age of 50. DDT causes high blood pressure.

       However, scientists cannot say that high pressure and hypertension is directly caused by exposing to DDT chemicals. High blood pressure can also be caused by previous diabetes, and factors like age, race, and body mass also contribute a part to it (Konkel and Environmental Health News 1). Many factors of high pressure and hypertension are not tested to confirm that DDT is the cause. “It also is impossible to know whether some women had undiagnosed high blood pressure or how blood pressure levels differed across exposure groups” (Konkel and Enviromental Heath News 1). High pressure can also be a result of obesity, sedentary lifestyle, and socioeconomic stress. There is not enough evidence to say that DDT is the cause.

       Scientific evidence, data, and research show that even though DDT does create a greater risk for high blood pressure, however many other factors can be contributed too. High blood pressure and hypertension are the worst things that we would ever want to be diagnose with. To prevent this from happening on any one of us, we need to make sure that we be extremely careful during pregnancy and keep track of what we eat every day.

Reading Response~anything #2


Title: Great Expectations
By: Charles Dickens

     Great Expectations written by Charles Dickens is regarded as a masterpiece of English novels. It narrates the story of Pip, an orphan boy who has good luck and great expectations, and then loses both his luck and expectations. 

     Pip has lost his parents when he was fifteen years old. He was brought up by his sister and her husband--Joe Gargery, a blacksmith who takes Pip on as an apprentice, teaches him his trade and makes friends with him. One day before Christmas, when Pip went to the churchyard where his parents were buried, he met an escaping convict-- Abel Magwitch. Pip brought cakes for the hungry man, which touched Abel deeply, although he was caught by police. After the Christmas, Pip was invited to play with Estella, a beautiful girl adopted by Miss Havisham. Miss Havisham was the richest man in the village. But she was very strange. She was dressed a bridal veil all the whole life after her fiancé left her at the wedding day, taking her a large amount of property. So she lived in the revenge and hated all the men. She treated Estella as a tool to take revenge on all man. When Pip met Estella, he loved her, so did Estella. But Estella knew she was just a tool to carry out the revenge plan of Miss Havisham, so she pretended to be proud, indifferent and look down upon Pip- a relative of a poor blacksmith, which broke Pip’s heart. As a consequence, Pip was determined to become a real gentleman who is in possession of money, good manners, luxurious life and a great expectation for Estella’s sake. Under the help of a stranger who donated a lot of money to him, Pip left Joe and the village, and went to London to live a luxurious life to learn to how to become a real gentleman. Pip started to waste money, look down upon other poor people, even including Joe, his brother-in-law and best friend! Gradually, Pip lost himself in the whirlpool of money, although he has had a large number of debts. As the same time, Estella has become more and more beautiful, graceful and brilliant. She walked in the crowd of men and married one of them as the Miss Havisham’s wish, which really tore Pip into pieces. And, as the same time, the mysterious benefactor of Pip came out. He is Abel- the escaping convict whom Pip has helped. When he escaped from the prison again, he earned much money and wanted to pay back Pip in that way. But Abel soon was caught by police and died. The properties he gave to Pip also were confiscated by police. Pip fell from the heaven to hell. He couldn’t stand it. As a result, he had a serious ill.

After receiving a letter describing the bad situation of Pip, Joe came to London to look after Pip in spite of the bad attitude Pip ever towards him. After recovering, Pip realized his wrong. He decided to be a gentleman by his own endeavor. So he came back to the small village and spared no efforts to make business with his friend--Herbert. Several years later, Pip met Estella again at the old house of Miss Havisham. After knowing her husband has died and the real reason why Estella didn’t choose him before, Pip made a proposal to her. At last, the two lovers were in together and Pip found his real great expectation at the end. 

     Among the characters, which impressed me most are not Pip and Estella who should be regarded as the leading roles, but Joe and Magwitch. I feel awfully sorry that I was not brave enough to read the original edition that is as thick as a brick. Otherwise, I may appreciate Joe and Magwitch more. Yes, they are not the main characters in the novel. However, what they said and what they did deeply touched me. It’s interesting, isn’t it? They are quite the opposite guys. One is a totally good man without the least bit of wickedness while the other is a prisoner who is believed to have committed every evil. I believe that everyone who reads the book is to like Joe. When he talked about his heavy drinking father who hit him a lot, he said he had a lot of love. Faced with his rude wife, he would rather seem a bit weak or foolish than stand

     However, I appreciate Magwitch, the bad guy. Magwitch did a lot of evil things when he was young. But how can you be unmoved when you get to know that the old man kept himself going just by thinking of the boy who once did him a small favor He lost his only daughter and Pip had no parents, so he considered himself as the boy’s second father, making up his mind to help his dear boy became a gentleman. He did every kind of job and led a hard life in Australia. At last he made a big fortune and promised himself that all the money would go to Pip. He could have led a better life in Australia, but he chose to go back to London .with the simple intention of seeing Pip, he went back at the risk of being hanged! “Whatever the fault he had from the start, remember, reader, he had a good heart.” Joe used these words to describe his father. But I think these words can better describe Magwitch. He lived with the fear of death all his life. Who shuts love out, in turn shall be shut out from love. However, thankfully, because Pip finally realized his good heart, his ending was peaceful.

When I finished reading the novel, I also take consideration to the question “what a real great expectation is?” In my opinion, great expectation does not means money, luxurious life provided by others, even the benefactors are your parents. It is our own dreams that we want to realize by our own efforts. Great expectation may be the further study, a respectable degree, a good job, a warm family or something else. But we must know that our future and great expectation must be mastered by our own. We should work for them, fighting for them, even dying for them, whatever. Only when we got what we want by our own endeavor, can we say we have had a great expectation.
