Some farmers in California are having a hard time picking their crops．There are not enough workers to help them with the harvest．

One farmer used to grow peaches (桃子), but will soon grow almonds (杏仁) instead．Peaches require more labor to harvest．They are easy to be damaged and need careful hand picking．He is now removing his peach trees．Then he will plant almond trees in their places． Almonds are harvested differently．It does not take as many workers to pick them because a machine shakes the almond trees．

The nuts fall on the ground and then are gathered up．The farmer does not have to hire many workers．

Some farmers think there are two reasons why they can' t find enough farm workers．One reason is that there are a lot of well-paid construction jobs in the are

A．Many people are taking these jobs instead of picking fruit．The other reason is that it has become more difficult for workers to come from Mexico into

California．Fewer workers are allowed to get into the country to work on the fruit farms．To settle the problem, farmers hope the government might allow these workers to work as guests．That would help workers provide for their family and help farmers harvest their crops．When the harvest season is over they' ll go back home．Farmers say that unless things change, more fruits will come from other countries．

This is because labor is cheaper in those countries than in the United States．

What will happen if the situation does not improve

Scientists have long tried to be able to know more about floods．So far, the best that scientists can do is to recognize the conditions for flooding．

Although deep snow alone seldom causes floods, when it occurs together with heavy rain and sudden warmer weather, it can lead to serious flooding．If there is a fast snow melt (融化) on top of frozen or very wet ground, flooding is likely to occur．Melting snow also causes high water levels in rivers．

Whenever rivers are already at their highest possible levels, heavy rains will result in the rivers' flooding the nearby land．

Rivers covered in ice can also lead to flooding．When ice begins to melt, it breaks into large pieces．

These pieces of ice move and float down the river．They can block the river, causing the water to rise and flood the land up the river．If the ice dam (坝) breaks suddenly, the large quantity of water held behind it can flood the areas down the river too．

Broken ice dams are not the only problem that can cause flooding．When a large human-made dam breaks or fails to hold the water collected behind it, it will also cause serious damage．

Although scientists cannot always know when floods will occur, they do know a great deal about when floods are likely, or probably, going to occur．

Scientists have long tried to be able to know more about floods．So far, the best that scientists can do is to recognize the conditions for flooding．

Although deep snow alone seldom causes floods, when it occurs together with heavy rain and sudden warmer weather, it can lead to serious flooding．If there is a fast snow melt (融化) on top of frozen or very wet ground, flooding is likely to occur．Melting snow also causes high water levels in rivers．

Whenever rivers are already at their highest possible levels, heavy rains will result in the rivers' flooding the nearby land．

Rivers covered in ice can also lead to flooding．When ice begins to melt, it breaks into large pieces．

These pieces of ice move and float down the river．They can block the river, causing the water to rise and flood the land up the river．If the ice dam (坝) breaks suddenly, the large quantity of water held behind it can flood the areas down the river too．

Broken ice dams are not the only problem that can cause flooding．When a large human-made dam breaks or fails to hold the water collected behind it, it will also cause serious damage．

Although scientists cannot always know when floods will occur, they do know a great deal about when floods are likely, or probably, going to occur．

It was Sharing Day! The teacher had asked the students to bring something interesting to class．

Jimmy found the little box he and Dad had made．Inside was a piece of rock, a sand dollar and a shark (鲨鱼) tooth．Nobody could have anything as interesting as these !

In class, Jimmy waited anxiously, hoping to be called on first by the teacher．But Kara was first．

She held up a sand dollar．Jimmy's eyes grew big．

"I found this on the beach, "Kara said．"It' s interesting．The little holes that make the sand dollar look like a flower are breathing holes．See all the needles They help the sand dollar move and dig into the sand．"

Jimmy was a little uneasy．Oh, well, he still had his rock and shark tooth．

Then Mark stood up． "This is my favorite rock, called pumice (浮石)．" Then Mark dropped the rock into a glass of water．"Look ! Pumice is the only rock that floats !"

Jimmy put up his hand and waved, but the teacher called on Justin instead．

"I found this shark tooth in Hawaii last Christmas, "Justin said．

The class was excited, but Jimmy lowered his head．"Sharks have rows of teeth．Every time a shark loses a tooth, another one takes its place．"Justin passed the tooth around．

Jimmy heard the teacher call him．He stood on one foot and then the other．"Well, ah, see．．．my treasure box is interesting ! It was just a piece of wood until Dad and I cut it into pieces and finally made a box out of it．It smells good, reminding us of camping．"

"What's inside" asked Lisa．

Jimmy opened his box．"A sand dollar, a piece of pumice and a shark tooth．"

His classmates' mouths dropped open．The teacher looked at the objects in the box and smiled．

"Now that' s interesting ! "he said．

On the Sharing Day, Jimmy_______．

Nineteen-year-old Melissa Goza couldn' t figure out why she failed to get a bank card time and time again．It only became clear when she was unsuccessful while looking for a new job in a Target store:Three different people are using her Social Security number (社会保障号)．

Target is one of the companies using credit (信用) reports when hiring new workers．At least one credit report didn't favor Goza in getting the job．A very low credit rate (评价) was under Goza' s Social Security number．Target, as required by law, told Goza why the company couldn' t offer her the job．

Sacramento lawyer Jennifer Shaw, a specialist in workplace law, says credit reports are just one more way employers use to find dishonest job seekers．"I think we need to know that, right now, there' s more information out there．And that means, there' s more information that can be used against us, "said Shaw．

Goza' s dark cloud may, however, have a silver lining．Target told her she' d be considered again for the job if she could get a letter from the Social Security Department proving that she' s the right owner of the Social Security number．

Now that Goza knows she' s suffered from other people' s wrongdoings, she will order copies of her credit reports to see what she can do to put things right．
