Electric ears are dirty.In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about "zero-emissions vehicles", but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---usually coal, oil,but also by heat generated in nuclear power plants. There are a few wind farms and geothermal plants as well, but by far we get electricity mainly by burning something.
In other words, those "zero-emissions" cars are likely coal-burning cars. It's just because the coal is burned somewhere else that it looks clean. It is not. It's as if the California Greens are. covering their eyes---"If I can't see it, it's not happening." Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it.But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat---at the generator, through the transmission lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars bum more fuel than gas-powered ones. If our electricity came mostly from nukes; or geothermal,or hydro, or solar, or wind,then an electric car truly would be clean. But for political, technical,and economic reasons,we don't use much of those energy sources.
In addition,electric cars' batteries which are poisonous for a long time will eventually end up in a landfill.And finally, When cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.

Pulling heavy suitcases all day in the summer is hard work, especially when you are a thin 14-year-old boy. That was me in 1940-the youngest and smallest baggage boy at New York City's Pennsylvania Railway Station.
After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it."
When I got home that night, I told my dad what I wanted to do. "You give an honest day's work," he said, looking at me straight in his eye. "They are paying you. If they want to do that, you let them do that."
I followed my dad's advice for the rest of that summer and have lived by his words ever since.
Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possession. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone.
Whether you're on a sports team, in an office or a member of a family. if you can't trust one another, there is going to be trouble. What can be inferred about the baggage boys?
| A．They could earn much, but they had to work hard. |
| B．Many of them earned money in a dishonest way. |
| C．They were all from poor families. |
| D．They were thin, young boys. |
What does the father's advice imply?
| A．It is wrong to give more to the passengers. |
| B．Don't believe them if they are paying you more. |
| C．Don't follow others to overcharge the passengers. |
| D．It is difficult to work hard and live as an honest boy. |
The underlined word "it" (in Paragraph 2) refers to______
| A．overcharging passengers |
| B．pulling heavy suitcases all day |
| C．paying passengers money |
| D．working in an honest way |
The writer can't put up with stealing because he thinks that _______
| A．it is a total shared experience |
| B．it is considered as the most dangerous |
| C．it does great harm to human relationship |
| D．it may led to the loss of his sports team. |
It can be concluded from the text that _______
| A．his father's advice helped him to decide which job to take up |

Say you're in the wine store and you want to buy something new. You have nothing to go by outside of the label. Will the label tell you anything you should know? Here's some general advice:
Vintage. This is the first thing we look for ourselves. You don't need to care whether 2001 or 2002 was a better year in the Sierra Foothills. The vast majority of wines at the store are meant to be drunk right away, so you make sure the wine isn't too old, particularly if you're buying it expecting lively, fresh fruitiness. We often see five-year-old Pinot Grigio and two-year-old Beaujolais Nouveau at stores, for example, so as soon as we see that kind of age on wines like those, we know we can skip them and move on(and possibly not shop there again).
Alcohol content. Too many wines have too much alcohol, which leaves them unbalanced. Sure, there are some classic wines with high alcohol levels, but many of today's regular table wines--Merlot, Chardonnay--have levels at 15% or above. Some of those might be terrific, but if we had nothing else to go on, we'd look for alcohol content at about 14% and below.
The more specific the better. A wine that says it's from Napa is probably a better bet than a wine that simply says it's from California. Unfortunately, this will also probably be reflected in the price, so this might not tell you much about value, If you care enough to know a few of famous vineyards for producing high-quality grapes, they might help you make an educated guess about quality.
Old vines. Theoretically, older vines produce fewer, but more flavorful grapes, but the problem is that no one has defined what an "old vine" is, so anyone can put this on the label. Just ignore it.
A phone number. You'd be surprised many small-production wines these days include a phone number on the back and an invitation to call the winerY, which is a sign of a highly personal winerY. We have called those numbers many times over the years and it's amazing how often the winemaker or winerY owner answers the phone. The underlined word "Vintage" in the second paragraph probably means "________ " .
| A．the place where the wine was made | B．the year when the wine was made |
| C．the freshness of the wine | D．the label of the wine |
It's better to buy
| A．five-year-old Pinot Grigio | B．the wine labeled from older vines |
| C．the wine from famous vineyards | D．two-year-old Beaujolais Nouveau |
From the passage we Can infer that
| A．the wine with high alcohol levels is definitely terrific |
| B．most wines at the store are intended to be drunk right away |
| C．older vines have lower production |
| D．some winemakers keep the promise all the time |
What is paragraph 4 mainly about?
| A．Geography. | B．Price | C．Quality. | D．Grapes. |
I was standing in the kitchen helping with dinner, asking my mom about my brother's doctor ' s appointment. They were testing him for autism(自闭症 ) .

I felt that same feeling I had in the bus line. The entire room was laughing when I raised my hand. " Yes , Alexis?" Mrs. Young asked. "I don't think we should make fun of the short bus, because there are a lot of people on that bus who have great personalities and have the same feelings as we do. And also ,I know some people on those buses and they are some of the most caring, sweetest, and smartest people , so I would appreciate it if you didn't make fun of them. "

A decades-old tradition, illustrated in a modem children's book, links the sweetness of honey with the joy of learning to read.
The grandpa held a jar of honey so that all the family could see. He then dipped a spoon into it and put some honey on the cover of a small book.
The little girl had just turned five. Stand up, little one, "he asked the girl softly. "I did this for your mother, your uncles, your
old brother, and now you ! "
Then, he handed the book to her. "Taste f "
She touched the honey with her finger and put it into her mouth.
" What is the taste?" the grandpa asked.
The little girl answered, " Sweet ! "

This is the beginning of a profoundly moving children's book entitled Thank You, Mr. Falker.
In this book, Patricia Polacco writes of her own passion to read, inspired by the honey on the book. It wasn't until fifth grade that she met her beloved teacher who provided the help that she needed to finally unlock the magic of the written world.

She spooned honey on the cover and tasted the sweetness---Then she held the book, honey and all, close to her chest.

Dear Mom, Clear My Calendar
September is around the corner, and some of us are already complaining about summer’s end. But parents have a special reason to do so. The end of summer means the start of school. And these days, planning a young child’s schedule is a big challenge. The challenge is no longer finding activities to fill a child’s day; it is saying no to the hundreds of options available. Our mailbox is filled with brochures urging us to sign our kids up for classes from cooking to martial arts(武术).
Educators are themselves discouraged by the number of special classes that many children attend. In the name of “enrichment,” three-year-olds not only go to preschool in the morning but study French or gymnastics after lunch. One teacher tells of a four-year-old asking for help in the toilet before hurrying off to tennis. Another teacher says that children sometimes hold on to her at pickup time. What happened to unstructured time?
A generous explanation is that we enjoy giving children opportunities we never had. The truth however is that many parents have doubts about how much time they spend away from their families. And one way to reduce this guilt is to believe that time spent in these classes is somehow more beneficial to children than the time we know we should be giving them ourselves.
David Elkind, an expert on children, suggests that the 1960s gave birth to the belief that earlier is better. Parents hope that early music lessons, for example will build a child’s confidence. The truth, however, is that any time children are asked to do too much, too soon, they are at greater risk for feelings of failure.
A child’s time does not have to be planned to be meaningful. Remember the lazy days of summer? Some children sleep late and play with the kids across the street until it’s time to come home for dinner. However, with the majority of mothers working, fewer children enjoy that idle (空闲的) time now.
Come September, children across the country will finish a full day of kindergarten, only to attend an after-school program until 6 P.M., when a working mom or dad comes to take them home. That’s too much for a five-year old. Finances, of course, do limit some parents. But let’s be honest with ourselves – our own busy schedules, whatever they involve, are no excuse for burdening a young child’s. The author holds that it’s a challenge to plan a schedule for a child mainly because _____.
| A．a child’s schedule is too complex |
| B．activities suitable for kids are limited |
| C．parents are stuck in numerous choices |
| D．children always say no to parents’ advice |
What the two teachers say in Paragraph 2 implies that _____.
| A．children love to stay at school |
| B．they are popular with children |
| C．children dislike after-school classes |
| D．after-school classes are of poor quality |
According to the author, what is the real reason for parents to send their children to after-school classes?
| A．Parents want to make up for their own regrets. |
| B．After-school classes develop children’s potential. |
| C．Parents have doubt about their own ability to guide children. |
| D．After-school classes give parents an excuse for being absent. |
Which of the following will the author probably agree with?
| A．For children’s benefits, the earlier the better. |
| B．Children’s spare time should be carefully designed. |
| C．Idle time for children is becoming a thing of the past. |
| D．Parents should be forgiven if they have a good reason., |
