Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour’s flight one of the scientists wrote in his book, “Look here for probable metal. ” Scientists in another airplane, flying over a mountain area, sent a message to other scientists on the ground, “Gold possible. ” Walking across hilly ground, four scientists reported, “This ground should be searched for metal. ” From an airplane over a hilly wasteland a scientist sent back by radio one word, “Uranium. ”

None of the scientists had X-ray eyes:  They had no magic power of looking down below the earth’s surface. They were merely putting to use one of the newest methods of locating minerals in the ground. . . trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing.

This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow in the surface.

At Watson Bar Greek, a brook(小溪) six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug out and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.

Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunks had more gold than those growing on the ends of the branches.

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag may feel extremely tired for several days. They may also have problems thinking clearly and remembering.
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.
The researcher took some saliva from the women”s mouths to measure levels of a hormone(荷爾蒙) that increases during stress(緊張). He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain”s temporal lobes(腦葉).
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently (永久性的) affect memory.
【小題1】According to the text, jet lag .

  1. can cause difficulties in speaking
  2. can make people feel tired for a few weeks
  3. can be only found in flight attendants
  4. can be caused by flying over several time zones
【小題2】It can be inferred from the text that .
  1. the conclusion is refused by many scientists
  2. scientists fear that this research is not done properly
  3. the scientific conclusion needs the support from many tests
  4. every women who were examined in the research were mot healthy
【小題3】From the result of the research we can see that .
  1. the women who have longer rest at home show better memory
  2. the women who fly in short time have smaller right temporal lobes
  3. the women who have longer flights fail the memory test
  4. the women who rest more than 14 days produce less hormones
【小題4】What is the subject discussed in the text?
  1. The cause of jet lag.
  2. A story of a group of flight attendants.
  3. The importance of having enough rest after flights.
  4. A research about the effects of jet lag on the brain.

FDA proposed the most sweeping food safety rules in decades, requiring farmers and food companies to be more cautious in the wake of deadly outbreaks in peanuts, cantaloupe (瓜），and leafy greens.

The long-overdue regulations are aimed at reducing the estimated 3,000 deaths a year from foodbome illness. Just since last summer, outbreaks of listeria (李氏桿菌）in cheese and salmonella(沙門氏菌）in peanut butter, cantaloupe and mangoes have been linked to more than 400 illnesses and as many as seven deaths, according to the Centers for Disease Control. The actual number of those sickened is likely much higher.

The FDA’s proposed rules would require farmers to take new precautions against contamination (污染）,to include making sure workers5 hands are washed, irrigation (灌溉） water is clean, and that animals stay out of fields. Food manufacturers will have to submit food safety plans to the government to show they are keeping their operations clean.

Many responsible food companies and farmers are already following the steps that the FDA would now require them to take. But officials say the requirements could have saved lives and prevented illnesses in some of the large-scale outbreaks that have hit the country in recent years.

In a 2011 outbreak of listeria in cantaloupe that claimed 33 lives ，for example, FDA inspectors found pools of dirty water on the floor and old, dirty processing equipment at the Colorado farm where the cantaloupes were grown. In a peanut butter outbreak this year linked to 42 salmonella illnesses ，inspectors found samples of salmonella throughout a New Mexico peanut processing plant and multiple obvious safety problems ，such as birds flying over uncovered trucks of peanuts and employees not washing their hands.

Under the new rules, companies would have to lay out plans for preventing those sorts of problems and how they would correct them.

“The rules go very directly to preventing the types of outbreaks we have seen/，said Michael Taylor, FDA’s deputy commissioner for foods.

1.The main task of FDA is probably______

A. to protect and promote the public health

B. to help those sickened recover

C. to research on food safety measures

D. to deal with water pollution

2.According to the passage, the new rules focus on_____.

A. inspecting the whole process of food production

B. improving food processing equipment on farms

C. preventing water pollution in food production

D. urging food companies to lay out plans

3.What does the word “they” in Paragraph 3 refer to?

A. Inspectors.    B. Farmers

C. Manufacturers. D. Workers.

4.Which of the following is TRUE according to the passage?

A. The new regulations should have come into practice earlier.

B. The 2011 outbreak of listeria is the most serious ever.

C. Farmers and food companies are strongly against the new rules.

D. Colorado and New Mexico are worst hit by food pollution.

Dear Guys,

I’d like to talk to you about the shame you subjected me to last night. Let me first refresh your memory: You, a group of fit, young men, were playing soccer on the field across from my apartment building. I, a better-than-average looking young woman, was walking along the sidewalk with my groceries. That’s when your ball came flying over the fence and landed in front of me.

One of you approached and asked politely if I would throw the ball back to you. Fighting the urge to drop my bags and run screaming down the street, I reluctantly (勉強(qiáng)地) agreed.

Before I continue, let me explain something that I didn’t have a chance to mention last night: I hate sports. More specifically, I hate sports involving balls. This results from my lack of natural ability when it comes to throwing, catching and hitting. I’m bad at aiming too. So you can understand why I’d be nervous at what I’m sure seemed to you like a laughably simple request.

However, wanting to appear agreeable, I put my bags down, picked up the ball and, eyes half-shut, threw it as hard as I could.

It hit the middle of the fence and bounced back to me.

Trying to act casually, I said something about being out of practice, then picked up the ball again. If you’ll remember, at your command, I agreed to try throwing underhand. While outwardly I was smiling, in my head, I was praying, Oh God, oh please oh please oh please. I threw the ball upward with all my strength, terrified by what happened next.

The ball hit slightly higher up on the fence and bounced back to me.

This is the point where I start to take issue with you. Wouldn’t it have been a better use of your time, and mine, if you had just walked around the fence and took the ball then? I was clearly struggling; my smiles were more and more forced. And yet, you all just stood there, motionless.

Seeing that you weren’t going to let me out of the trouble, I became desperate. Memories of middle school softball came flooding back. I tried hard to throw the ball but it only went about eight feet, then I decided to pick it up and dash with ball in hand towards the baseline, while annoyed thirteen-year-old boys screamed at me that I was ruining their lives. Children are cruel.

Being a big girl now, I pushed those memories aside and picked up the soccer ball for the third time. I forced a good-natured laugh while crying inside as you patiently shouted words of support over the fence at me.

“Throw it granny-style!” one of you said.

“Just back up a little and give it all you’ve got!” another offered.

And, most embarrassing of all, “You can do it!”

I know you thought you were being encouraging, but it only served to deepen the shame.

Anyway, I accepted your ball-throwing advice, backed up, rocked back and forth a little, took a deep breath and let it fly.

It hit the edge of the fence and bounced back to me.

I surprised myself-and I’m sure you as well-by letting out a cry, “DAMN IT!!!” I then willed myself to have a heart attack and pass out in front of you just so I’d be put out of my misery.

Alas, the heart attack didn’t happen, and you continued to look at me expectantly, like you were content to do this all night. I had become a sort of exhibition for you. I could feel your collective thoughts drifting through the chain-link: “Can she really not do it? But I mean, really?”

Unfortunately for you, I wasn’t really game to continue your experiment. Three failed attempts at a simple task in front of a group of people in a two-minute period was just enough blow for me for one night. I picked up the ball one last time, approached the fence and grumbled, “Please just come get the damn ball.”

And you did. And thanks to you, I decided at that very moment to never throw anything ever again, except disrespectful glances at people who play sports.

Sincerely, Jen Cordery
