作為雅思考生，我們讀外刊要有一定的目的性，不僅僅是為了擴大我們的閱讀面，還要有意識地針對雅思考試，提高自己的水平。希望大家不幫是看源文內容，更要對文中注釋加以學習消化，希望對大家有幫助!

Jetlag may be the worst part of traveling. And it hits many people harder traveling east than west. Why they feel this way is unclear. But scientists recently developed a model that mimics special time-keeping cells in the body and offers a mathematical explanation for why traveling from west to east feels so much worse. It also offers insights on recovering from jet lag.

時差應該是旅行中最討人厭的事了。許多向東行的人又比往西走的更容易受時差影響。我們并不清楚為何這些人會有這種感受，不過科學家近來設計出一套模型，來模仿人體內專門計時的細胞，用數學說明為什么從西向東走造成的時差更難捱。這項研究也讓我們更加了解該怎樣倒時差。

【經典句式】

jet lag時差

model模型

time-keeping計時

【大作文萬用句式】

… offers insights on …讓我們更加了解…

Deep inside the brain, in a region called the hypothalamus (right above where our optic nerves cross) the internal clock is ticking. And approximately every 24 hours, 20,000 special pacemaker cells that inhabit this area, known as the suprachiasmatic nucleus, synchronize, signaling to the rest of the body whether it’s night or day. These cells know which signal to send because they receive light input from our environments— bright says wake, dark says sleep.

在人腦中央深處有個叫做下丘腦的部位(就在視神經交叉處正上方)，生物鐘就在這里運轉。大約每隔24小時，2萬個位于下丘腦“交叉上核”的特殊節律調節細胞就會同步一次，向身體其他部位發出信號，告知身體現在是白天還是黑夜。這些細胞知道該打什么信號，因為它們從環境中接收光線刺激，明亮時就表示人該醒著，昏暗時就該睡覺。

But when you travel across multiple time zones, like flying from New York to Moscow, those little pacemaker cells that thought they knew the routine scramble around confused before they can put on their show. The whole body feels groggy because it’s looking for the time and can’t find it.The result: jet lag.

然而，當我們跨過好幾個時區，譬如從紐約飛到莫斯科的時候，這些自以為通曉例行公事的節律細胞就被打亂了，不知該怎么辦才好。我們的身體也糊涂了，因為它想要對時，卻不知道是什么時間。結果就導致了時差。
