A study suggests that a woman’s blood group could influence her chances of getting pregnant.
一項研究顯示，女性的血型可能會影響她受孕的機會。
Researchers who tested a group of women seeking fertility treatment found those with the blood type O appeared to have a lower egg count and poorer egg quality than others. By contrast those with blood type A seemed to have More and better quality eggs.

The findings could lead to women with type O blood being advised to try for a baby earlier, but experts said more research was needed before such a step was taken.
這一發現可能會幫助"O型血"婦女接受建議，嘗試更多辦法，更早的懷上小孩。但是專家說在採取這樣的方式之前，還需進行更多的研究。
The lead author, Dr Edward Nejat, of the department of obstetrics and gynaecology at the Albert Einstein College of Medicine in New York, said his findings were based on women having fertility treatment at the Yale University and the Montefiore Institute in New York.
研究領導者、紐約阿爾波特?愛因斯坦醫學院婦產科系愛德華?奈加特教授說，他的調查是對正在耶魯大學和紐約蒙特菲奧裏研究所接受生育治療的婦女進行研究而來的。
The study of 560 women, whose average age was just under 35, found that those with blood type O were more likely to have higher levels of “follicle stimulating hormone” (FSH) than those with type A.
接受調查研究的560位女性平均年齡在35歲以下，研究發現"O型血"婦女的卵泡刺激素(FSH)的數值比"A型血"婦女要高。
Fertility experts regard a high FSH level as a key indicator of having a low egg count. FSH is produced by the body to stimulate the follicles in the ovaries that produce eggs.
生育專家將卵泡刺激素的數值作爲重要指標來衡量女性體內卵子數量，數值高則卵子數量少。卵泡刺激素由體內產生，以刺激卵巢中的卵泡產生卵子。
As a woman’s ovaries run out of eggs in her 30s and 40s, production therefore has to be stepped up to encourage more eggs. The presence of high levels of FSH indicates lower numbers of eggs.
處於30歲到40歲之間的女性，她們的卵巢可能就不再產生卵子，所以需要通過(其他方法刺激)讓其產生更多卵子。高數值卵泡刺激素則意味着更少的卵子。
The study found that women with blood type O were twice as likely to have an FSH level above 10 as those in any other blood group.
研究發現，"O型血"婦女體內的卵泡刺激素數值很可能是其他血型婦女的兩倍，數值在10以上。
People with blood group A carry the A antigen, a protein on the cell surface, that is absent in people with O type.
"A型血"人羣體內攜帶A血型抗原、一種細胞表面的蛋白質，這種蛋白質在"O型血"人羣中是沒有的。
考研英語閱讀精華美文2：Studying for an exam while listening to music is not smart, because background music can impair your ability to perform memory tasks, new research has found.
最新研究發現，邊聽音樂邊複習功課並非明智之舉：因爲背景音樂會降低你完成與記憶力相關的任務的能力。
Study participants were asked to recall a list of eight consonants in the order they were presented. They did this while in five different sound environments: quiet surroundings; music they liked; music they disliked; changing state (a sequence of random digits); and steady state (a sequence of steady digits such as “3, 3, 3, 3”).
參與調查者聽到8 個輔音字母，他們必須按照播放順序進行復述。他們聽的時候，分別處在5 種不同的背景聲音中：安靜環境、喜歡的背景音樂、不喜歡的背景音樂、數字不斷變化的響聲，數字不變的響聲(例如：3，3，3，3)。
The participants’ recall ability was poorest when listening to music, regardless of whether they liked or disliked it, and in changing-state conditions. The most accurate recall occurred when participants performed the task in steady-state environments, according to the study published online in the journal Applied Cognitive Psychology.
結果顯示，無論他們喜歡還是不喜歡背景音樂，在播放音樂和數字不斷變化的聲音環境裏，被調查者的記憶力都最差。該研究發現刊登在《應用認知心理學》上，研究指出人在安靜環境下記憶力最好。
“ The poorer performance of the music and changing-state sounds are due to the acoustical variation within those environments. This impairs the ability to recall the order of items, via rehearsal, within the presented list, ” explained lead researcher Nick Perham, a lecturer in the School of Psychology at the University of Wales Institute in Cardiff, in a news release from the journal’s publisher.
威爾士大學卡地夫學院的首席研究員尼克·珀罕在該期刊的新聞發佈會上說：“音樂與不斷變化的聲音影響了人們的表現，這是因爲那些環境聲音變化會影響人們複述測試內容的能力。”
“Mental arithmetic also requires the ability to retain order information in the short-term via rehearsal, and may be similarly affected by their performance in the presence of changing-state, background environments,” he added.
“心算也需要通過練習在短時間內記住信息的順序，因此也可能受到背景環境的影響，”珀罕補充道。
When performing a challenging mental task, do it in silence, Perham recommended.
珀罕建議人們應該找一個安靜的環境來完成一項具有挑戰性的腦力勞動。
