Having taught English in an senior high school for 26 years, my teacher has developed the habit of trying to make his students to get good marks in exams. But some textbooks who include dozens of mistakes will have a seriously bad influence in students. Since he's found out over 30 real mistakes in your last 3 textbooks nothing, I firm believe that he can still find out other mistakes in your next textbook for free. Wishing us to use good textbooks than before, he's willing to proofread（校对）it before it was printed. Frankly spoken, my honest and responsible teacher has no intention of looking down upon you textbooks.

3 . Earth Hour is organized by the World Wide Fund for Nature. It's a big event usually at the end of March every year. On this evening, people “go dark”.     1    

It's true that turning off lights for just one hour saves only a small amount of power.    2    On one level, joining in Earth Hour makes people think about the problem of climate change and what we can do in everyday life to protect nature.

But on another level, a large number of people’s acting together sends a powerful message to governments and companies.     3     They begin considering green issues when big decisions.

The logo(标识) of Earth Hour is “60+” .The number 60 is for the 60 minutes of Earth Hour.     4     In fact, people who join in Earth Hour say that taking part makes them want to do more for the environment.

    5     Musicians give concerts by playing acoustic(原声的) instruments instead of electric ones, and using candles instead of electric lights. Celebrity chefs have created special recipes for families to prepare and eat by candlelight. Tree-planting sessions, group walks and runs are also among the options.

4 . In general, elderly people, after retirement, can spend time in_______such as taking care of their grandchildren, traveling around, taking part in group dancing,_______, attending special classes. But after 70, when their responses start slowing and health begins declining, they have to find ways_______their remaining years in relative comfort.

The majority would prefer home-based care,_______has been the tradition in China,_______it allows them to live in a familiar environment, preferably in the company of their children and grandchildren. But the problem is that China’s_______big families with three-to-four generations living_______ one roof is fast becoming history. Usually, elderly parents and their grown-up children live in different parts of a city, even in different cities or different countries,_______it difficult or impossible for their children to take care of them.

_______the grown-up child lives only a few kilometers away in the same city, he finds it difficult to attend to his parents, as________he is the single child of the parents.

The government is encouraging home-based care for the aged not only because it is the top choice of the elderly________   because it is perhaps the only workable solution to the aging society problem. By the end of last year, China had more than 250 million people above the age of 60________about 29 million above 80, It is too large a group for any government or social organization________ .

To help the elderly people, the government is sponsoring day-care centers in local communities in many cities, where the government ________housing space and part of the funds to the centers which________by the local communities. The elderly people, after paying a lump sum(一次性付款), can enjoy meals, chat with their peers, exercise or________a nap in the daytime in these centers.

For those who prefer to stay________, information about their health and special requirements are collected by the community nursing center which, at a phone call, can________send people to their homes to help them with cooking, shopping, cleaning and dealing with any emergencies. Though this form of caring for the aged is welcome, it is________to be adopted nationwide________ some poor cities don’ t have enough resources to run such centers and services.

5 . A Great Way to Teach Children to Take Responsibility

As parents, one of the most important things to teach children to take responsibility is to include chores as a part of their daily routine. In order to make a family function smoothly, every member must contribute. Teaching your children to take responsibility at an early age makes it easier for them to shoulder greater responsibilities as they grow older.

    1     If your children leave their crayons lying on the table after drawing, picking up those crayons is not a chore. It is cleaning up a mess they have created.     2    

    3    . For example, if it is to feed the dog every day, make   sure   the   children understand that if they fail in their responsibility, the dog will go hungry.

Make rewards and punishments a part of the lesson. Together decide whether they will be rewarded or not.     4     Some parents make their reward a monetary payment, while others choose to reward with certain privileges, such as extra television viewing time.

Children need to be taught that there are punishments for their actions in case of not doing their assigned chores. Decide and agree from the start what the punishment will be.

Teaching your children the importance of contributing to the family is of great importance.     5     By taking this step, you have done a wonderful thing for your children by providing them with life skills they can take with them into society.

6 . “Smombies”— people walking while staring at their smartphones are very real and a growing cause for concern. To let people pay more attention to their surroundings to avoid serious accidents, government in a small German town has come up with a more positive solution — embedding (嵌入) traffic lights in the pavement to make them noticed by people always looking down at their phones.

The safety measure was taken. Authorities in Augsburg decided to act, installing ground level traffic lights at two tram (电车) stops last Tuesday. The lights flash red when a tram is coming, or when the regular traffic light turns red. “We realized that the normal traffic light isn't in the line of sight of many pedestrians these days,” said Tobias Hermes, a city official. “So we decided to have an extra set of lights — the more lights we have, the more people are likely to notice them.”

Some Augsburg people appear to be quite happy with the idea. “I think it makes sense,” Jack Smith said, speaking to The Augsburg Alleghenies. “One always sees young people these days running over red lights. This makes it more obvious that you need to stop.”

Others, however, found the need for ground traffic lights unnecessary and even frightening. “I find it scary that smartphone users are so engrossed that they need to install lights in the ground so that they notice the tram coming,” one person told the local paper.

But do this kind of pavement-embedded lights actually work? One interviewed teenager believes not really. “To be honest, I didn't even notice it,” he told The Augsburg Alleghenies. "Maybe it’d be useful at night, but I didn’t realize it was there until just now.”

7 . Clothing rental is a hot new industry and retailers (零售商) are demanding to get on board in hopes of attracting green shopper.

But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated (调查) this question and concluded that it's not as sustainable as it seems.

Take shipping, for example, which has to go two ways if an item is rented — receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.

She writes, ''An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's.''

Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high impact and polluting process. All the rental services that Cline looked into have replaced perchloroethylene (氯乙烯), a carcinogenic (致癌的) air pollutant, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great either.

Lastly, Cline fears that rental services will increase our appetite for fast fashion, simply because it's so easily accessible. There's something called ''share washing'' that makes people waste more precisely because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as ''a way to share rides and limit ear ownership.'' and yet ''it has been proven to discourage walking,bicycling, and public transportation use.''

Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step — that's wearing what is already in the closet.
