There are long rivers, and there are famous rivers. The Nile is the world’s longest and most famous river. It runs 6, 650 kilometers. Crocodiles and hippos live in its waters. Pyramids built by ancient Egyptians rise along its banks.
The main branch of the Nile, the White Nile, starts just above Lake Victoria, the world’s second largest fresh — water lake, in east central Africa. Then it flows to the north. At Sudan’s capital, another great river called the Blue Nile joins the White Nile. Together, they form one very powerful river. Then it goes through Egypt’s famous Nile Valley before reaching the Mediterranean Sea.
Ancient Egypt, the first great African civilization(文明), started along the banks of the Nile more than 5,000 years ago. Ancient Egypt ruled the Nile Valley for thousands of years. Great pyramids and temples were built on the banks and we can still visit them today.

Most of us use alarm clocks or mobile phones t0 wake up at the right time for school or work. We lo at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine. We can’t look at a clock for the right time for these activities. We must listen to the clock inside our bodies, the biological clock.
Barbara Wells exercised every morning. She woke up at 6:00 a. m. She ran about two miles before she went to work. But Barbara's legs and back started to hurt. She did some exercise before she ran. But her legs and back still hurt. She ran slower, but the pain didn’t stop. Barbara talked to her doctor. The doctor said, “Don’t run in the morning. Try to exercise later in the day. That is the time when your body is at the right temperature for exercise after work. Her legs and back didn’t hurt any more.
Today, doctors are learning more shout chronobiology(生物钟学)，the study of biological docks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep on time every right and to eat only when they’re hungry. Also, doctors discovered that some illnesses, such as heart attacks, occur (v. 发生) most often in the morning. This information tells them that the best time to take heart medication may be at night. When patients take heart medication at night, they may prevent a heart attack in the morning.
Many doctors believe chronobiology can help us live healthier lives. It may be the right time to listen to these doctors!

Dear Nancy’s parents,
My daughter had a bullying (欺凌) problem a couple of years ago. It wasn’t easy, but I ended it. When things are a serious as you describe, it is no time to be silent. These kids probably know each other from school, so take the rude text messages sent by the bully directly to the headmaster and show him. Describe to him how it is affecting your 13-year- old daughter. Tell him you will not stand it and you want him to put an end to it now.
Bullying is a dangerous and serious offense these days, and any good headmaster will take your charges seriously. He will probably address the issues with the parents. If they are crappy parents, then they may do nothing to their child. You may have to repeat this process several times, but you need to keep a check on those text messages and don’t allow your child to delete them.
Now is the time to draw your child close and take care of her, because she needs it. My daughter did not like me being involved(参与的)either, but you are the only hope she has of solving this problem, so do it and mean business. Always be polite but straightforward. The headmaster and the parents must know you mean business.
If repeated meetings with the headmaster (and parents, if he allows it) does not solve the problem, then I would consider hiring a lawyer. That will send the message across loud and clear. When you are talking about financial loss, most parents will stand up and take notice and act to keep their kid under control!
Good luck — I wish you the best in this terrible situation.
Yours,
Rachel

Today, the world’s diversity(多样性) of food crops is quickly decreasing. But scientists around the world are taking action. They are building seed banks. At seed banks, scientists store the seeds of many different crops.
There are now 1,400 seed banks around the world. However, some banks are in warm countries. If the electricity fails, the seeds will get too hot and die. Other seed banks are in countries troubled by war. Sometimes people damage the seed banks. If this happens, valuable seeds can be lost forever!
The organization Global Crop Diversity Trust decided they wanted to deal with this problem. So, they decided to build a global seed bank. This seed bank would contain a back-up, or extra copy, of all the world’s seeds. Smaller seed banks would still collect and keep local seeds. But they would also send copies of their seeds to the global bank.
Scientists from the Global Crop Diversity Trust chose the cold, snowy mountains of Svalbard, Norway to build the global seed bank — the Svalbard Global Seed Vault. Organizations, farmers, or local seed banks store their extra seeds there. And the people who place their seeds in the vault are the only people who can take them out. They pay to ship their seeds to Norway, but it does not cost them any money to store their seeds. The Global Crop Diversity Trust pays for this.
Cary Fowler is a scientist who heads the Global Crop Diversity Trust. He said, “If the Seed Vault simply supplies seed banks with copies of seeds that those banks lost by accident, the Seed Vault will be worth way more than it cost.”
