Researcher Robert Engelman from Population Action International says by the year 2025 about 3000 million people may lack water. At least 18 more countries are expected to have serious water problems. The need for water keeps increasing.

    Mr Engelman says the population in these countries that lack water is growing faster than in other parts of the world. The report says lack of water in the future may result in(导致)several problems. It may even increase1problems. Lack of water often means drinking water isn't safe. Mr Engelman says there are problems all over the world because of diseases, Lack of water may also2more international con flint(冲突), Countries may have to compete for water in the future. Some countries, such as Egypt, the Netherlands, Cambodia, now get sixty percent of their fresh water from other countries. And the report says lack of water would affect(影响)the ability of developing to improve their economies. This is3new industries(工业)offer need a large amount of water when they are beginning.

    The Population Action International study gives several solutions4the water problem. One way, it says, is to find ways to use water for more than one purpose.5way is to teach people to be careful and not to waste water. A third way is to use less water of agriculture, The6also says long-term(长期的)ways of dealing with the water problem must include controls on population growth.

Dan is a Grade 7 student and he is 13 years old. He lives on Oak Street in Toronto, Canada. Dan is waiting for the bus because he is going home now. There are also some other people waiting at the bus stop. Dan is looking at them and thinking about where they are going.

There is a short man. He is wearing a blue jacket and a baseball cap. He is reading a map. Maybe he is a tourist(旅游者).There is an old man with glasses. He looks like Dan's grandfather. Dan wants to know where the old man is going. Is he moving to a new town? There is a girl standing near the old man. She looks very worried and is looking at her watch. Maybe she is late for work.

The bus finally comes and Dan gets on with the other people. Dan thinks he can write a story about the people he saw at the bus stop today.

My son Sam is 16 and autistic (患自闭症的). It was Sam's very first day at high school. We'd set up a 1 of how he'd get home: I'd pick him up outside the 2 near his school at 3:30 p.m.

Unknown to me, very bad weather was on its way, and I was 3 . But because of his dead phone battery, I was 4 to communicate that to him. 5 , he became very upset and frightened outside the shop, exactly where I'd told him to wait.

This was 6 a beautiful old lady not only went to check on him, but took him inside her shop, 7 him down, got my phone number from him and called me. After that my son would go into her shop every afternoon, buy a drink and have a 8 .

Sam graduates this year, and I'm increasingly feeling the need to 9 the shop to let this 10 lady know that she helped Sam, and that she saved me from the situation. I'm not sure if I can 11 all of this, but at least I will get to thank her.

There are people I will not get to thank, though — the many kind strangers who have been there for Sam. And believe me, if you're wondering if this world is a complete 12 right now, I'm here to say that it is not.

So I guess this is a love letter to those of you who have helped a 13 out of the goodness of your heart. Please know that you as well as your beautiful heart and kindness are 14 , and perhaps 15 , you have made a great difference in someone's life.

①Almost every kid on the planet loves snacks, but they seldom care how unhealthy those snacks are. Some snacks like chocolate and candies are found everywhere, however, others are unique to a country or a culture. 

②In Japan, Matcha(抹茶) is a kind of green tea powder. It is made from tea leaves and can be used with ice cream or cake. In fact, Matcha came from China first but took off in Japan. Biscuits or cookies covered with chocolate are also a Japanese favourite. 

③Potato chips and French fries are very popular in the US. They are cheap but tasty. But they are high in calories and eating too much may make you fat. Popcorn is another typical snack. People eat it when they are watching sports games or visiting the amusement park. Most cinemas also sell popcorn. 

④In the UK, many people sit down for snacks at around 4 pm every day. They call it"afternoon tea". Traditional afternoon tea is biscuits and tea. People also have scones(烤饼) with jam and cream, which is probably the most classical English snack. Potato chips and French fries are popular in the UK too. 

⑤Do you want to eat snacks in a healthy way? Here are some helpful tips. Have a look! A handful of walnuts (核桃) are great for your brain. But a whole bag will add nothing but fat. If you're crazy about chocolate, try a hot chocolate drink instead of a chocolate bar. Don't eat too many snacks after dinner. 

In 1988, a serious earthquake hit Armenia. It killed(杀死)about 25,000 people in less than four1 . A father rushed to the school where his son was,2 to find that the building was flattened(变平).

But he remembered the3 he had made to his kid, "No matter4 happens, I'll always be there for you!" Tears began to fill his eyes. He ran5 to the place where his kid's classroom had been and started digging(挖掘).

Other parents tried to pull him out of what was left of the6 . To each parent, he asked in a7 voice, "Are you going to help me?" Then he went back and8 his digging, stone by stone.

A firefighter(消防员)9 and tried to pull him away. The police came as well. To them, he asked the 10 question, "Are you going to help me?"

He dug11 eight hours...18 hours... 28 hours... And then, in the 38th hour, he pulled back a12 and heard his son. He called his son's name, "ARMAND!" He heard back, "Dad? It's me. Dad! I told the other kids not to worry,13 I'm sure that you would come to save us."

"What's going on in there?" the father asked.

"There are 14 of us left out of 33, Dad," his son answered.

"Come on out, Son!"

"Let the other kids out14 . I know you'll get15 ! No matter what happens, I know you'll always be there for me!"
