The trip by railroad from village to city center graphically illustrates the integration of rural spaces into the urban fabric.The image of these speeding inter-city trains indeed has become a virtual new wave in which the station and the sound of the train in the distance articulate memory and narrative,and becomes shorthand for mutations in the event.The commuter train getting in and out of the area of the railway station circumscribes the cityscape and is abstracted by it.

Passage 2
Are you carrying too much on your back at school?You're not alone.Back experts in the United States are worried that young students are having back and neck problems as a result of carrying too much in their backpacks (schoolbags).
"It hurts my back when I run," said Oberlin Reyes,a student in Virginia."It's hard to get up the stairs with my backpack,because it's too heavy."
Oberlin is among students whose backpacks were weighed for a week in a recent study.
They had regular backpacks with two straps (带子) to carry them,but a number of students with heavy loads had switched to rolling backpacks (which have wheels and can roll on the ground).
Shirley Park,whose backpack weighed 10 kilograms,said she changed to a rolling backpack because she was starting to have back pain.
How much is too much?Experts say students should carry no more than 10 to 15 percent of their own body weight.A few students had one suggestion to lighten the load:less homework.
P.S.(附言) Doctor's suggestion:
① Lighten the load.Clean out binders (活页材料) and take home only the books you need that night.
② Wide straps are better.They send out the weight over your shoulders more evenly (均匀).And be sure to wear both straps rather than hanging the pack over one shoulder.
③ Pack smart.The heavier things should be packed closed to the back.④ Bend both knees when you pick up the pack,and don't just bend over at the waist (腰).（273 words）

第一部分：
Components of clutter
This raises the question:What other ads does a particular brand compete with?In the broadest sense it competes with all other ads-even those not in the same product category.This is known as the general level of on-air clutter and any ad has to break through it.This general level of clutter is relatively constant,at least in the short term.However,it has tended to grow over the long term not only because of more time given to ads but also because of an increase in the use of shorter-length commercials.Shorter-length commercials boost the total number of commercials on air and thus the number that people see in any given time period,and increases the general impression that there is more advertising overall.
As well as the general level of clutter there is,even more importantly,category clutter.The ad in question competes with other ads in the same product category.This is called category clutter ,and this does vary from week to week.
What may be surprising to many readers is that the ad also competes with any other ads for the same brand that may be aired in the same week.That is,multiple but similar advertising executions for the same brand frequently compete among themselves and can set up interference effects that impede their individual effectiveness(especially with low-involved audiences).

我会怎么想呢?我会想起,you are here,我会想起 give me a hand.然后呢?没有头绪.
