Europe’s deadly outbreak of a rare form of E. coli bacteria (大腸桿菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(腸) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.

三．閱讀理解：（20×2.5=50分）
People have smoked cigarettes for a long time. The tobacco used to make cigarettes was grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking, and soon the dried leaves were transported to Europe where smoking began to catch on. In the late 1800s, the Turk(土耳其人) made cigarettes even popular.
Cigarettes smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases breathing rate.
Smoking cigarettes is dangerous. The U.S. Public Health Service stated that cigarette smoking is the cause of lung cancers and several other deadly diseases. The U.S. government now requires that each package of cigarettes bear（帶有）a special warning about the danger of smoking.
1. The expression “catch on” in the passage may mean _________.
A. start B. cost a lot C. become popular D. dangerous
2. Before Columbus discovered America __________.
A. Europeans had smoked B. Nobody smoked in the world
C. Nicotine was not in tobacco D. Europeans had never smoked
3. In the nineteenth century smoking became popular because of the people in ________.
A. India B. Turkey C. the U.S. D. British
4. Breathing is affected by ___________.
A. nicotine B. tar C. heat D. both A and B

The days of Europeans relaxing in the cafe with a newspaper and a seemingly endless cup of coffee appear to be numbered．A new English expression is popular in Europe these days：“coffee to go．”
“Five or ten years ago it was much more normal to sit in a cafe for several hours than it is nowadays，”says Joann，who works in a central Berlin coffee bar owned by the Canadian coffee and bakery chain Tim’s.
“There is a trend towards a more fast-paced life．But people still act surprised when you ask if the coffee is‘to go’．You mean I can take it with me? they ask..”
“Europe is often five or eight years behind trends in America，”says Joann.“In the States.‘coffee to go’is part of everyday life.”
Owing in part to Starbucks，it appears to be very much part of everyday life in many other countries too．
The Seattle-based group compete with a growing number of global chains in attempting to reshape coffee drinking cultures in regions including Asia and the Middle East．
The US is the model for continental Europe’s new“coffee to go”culture：Each of the new cafe bars offers bagels，muffins，brownies and cookies to go with the coffee.
But then,“coffee to go’’might sound a little odd to English ears used to the words “takeaway”or take one．
It does sum up the brisker pace of life since the city resumed its status as the German capital following the fall of the Berlin wall in 1989.
As one more sign of the changing times，one of Berlin’s most venerable(古老而莊重的)coffee houses，cafe Einstein，has followed the trend by opening a small chain of coffee shops across the city．
Taking coffee,slowly and in decorous（端正的）surroundings,has been a feature of European coffee houses,particularly in German speaking countries,for decades.
For the elderly citzens of Vienna it amounts to a ritual（儀式）when they gather in coffee houses around the city for a cup of their favovrite drink and a piece of rich,creamy cake.
1.From the passage,we can see that .
A、“coffee to go” springs in Europe these days
B、Europe is often a few years before trends in America
C、America often follows Europe’s “coffee to go”culture
D、it’s easy to reshape coffee drinking cultures in the Middle East
2.Every new cafe bar offers some to go with the coffee
A、food B、newspaper C、drink D、music
3.More and more Europeans have takeaway coffee because .
A、Europeans live a more fast-paced life now
B、The coffee is much cheaper
C、Europeans are used to taking away the coffee
D、the coffee is easy to take away
4.The characteristic of European coffee houses is .
A、“coffee to go ”as part of daily life

C、having coffee slowly in a pleasant atmosphere
D、taking away coffee in a hurry
