Emily and I are twins. We love cooking healthy food together! Our parents have always cooked at home. They really
16． us a lot.

Working as sisters is interesting, as we have been through a large number of
17． experiences. However, sometimes we’d like more space of our own in the kitchen. We try to be fair. If one person manages to
18． a dish, the other person will write the process and take photos. Then we’ll change jobs next time.

Our dishes are so popular that we have been invited to be
19． for the Food and Health section in our school newspaper.

Sometimes not everything works out perfectly – and that’s OK! For example, we don’t know
20． what the readers want, so it’s quite hard to choose a widely accepted picture of the food. But we try our best to meet their
21．. We discuss the work and help each other to improve. That’s the best part about working together. We have been awarded “Best Campus Cook” several times for our
22．.

We love making new dishes, taking pictures, and then posting them on our school newspaper. It’s always good to try new things –
23． with food! When you eat healthily, it makes you feel better, and it can be twice as delicious.

   What do you need for an invention to be a success?

To begin with, good timing is very ________. You can have a good idea which the public doesn’t want yet. Take Giovanni Caselli as an example. He invented the first fax machine in the 1860s. Though the quality was excellent, his invention quickly ________. The fax machine did not become a necessary piece of equipment in every office until the 1980s.

Money also helps. The Frenchman Denis Papin had the idea for a steam engine almost a hundred years before James Watt was born. Denis never had enough money to ________ one.

You also need to be patient. It took scientists nearly eighty years to invent a light bulb. ________, you shouldn’t be too slow. In the 1870s, Elisha Gray developed plans for a telephone. Gray saw it only as “a beautiful toy”. When he finally sent details of his invention to the Patent Office (专利局) on February 14th, 1876, it was too ________. Almost the same designs hadarrived just two hours earlier. The young man who sent them was Alexander Graham Bell. He isremembered as the inventor of the telephone.

Of course what you really need is a wonderful idea. If you haven’t got one, a walk in the countryside and a careful look at ________ can help. The Swiss scientist, George de Mestral, had the idea for Velcro (粘扣) when he found his clothes covered in sticky seed pods after a walk in the countryside.

It’s 5:00 a.m.! A morming call wakes up Marco. He doesn’t get up so e
51． at home in Los Angeles. Well, maybe to eat breakfast once in a while but never to herd (放牧) cows and sheep! But Marco isn’t at home. He is in Africa, on the grasslands of Kenya (肯尼亚). He is living with the herdsmen.

“Life is very different in Kenya. People live a p
52． life here on the grasslands. They can’t afford TVs, cars or mobile phones. They make a living mainly by herding cows and sheep,” Marco says.

Marco’s trip to Africa isn’t a h
53．. It’s part of the school project for biology course at Sunshine School. The school hopes the students will have more life experiences. They have never been to Africa. Kenya is a country which is c
54． new to the students from Los Angeles. When the students get there, they put on local clothing. Boys herd cows. Girls collect firewood and water. Families depend on their cows. As a result, the herdsmen and the students have to m
55． from one area to another so that the cows have more grass to eat.

Now in Los Angeles, Kenya is on the minds of the students at Sunshine School all year. Disasters have killed many cows in Kenya, so the students decide to raise money to b
56． cows for the local people. Each cow costs about $100. “One cow means more to the health of a family than money,” says Marco. “Here we are really giving life. A cow will give a kid milk every day.”

The school wants to give the students a different way of thinking. Helping the herdsmen in Kenya is just the first s
57．. Next, the students will try to discover ways to give a hand to those in Los Angeles who need help.

Triathlon is a race in which each person swims, rides a bicycle and runs over very long distances. It has been held ten times in Hope Town. Sam, aged 20, finished nine races with his younger brother Luke. Every race was a victory for them. Luke can’t walk, talk or feed himself because of a rare brain illness since birth. But Sam wants his brother to know what it feels like to be part of a sport instead of having to sit and watch. A local TV journalist interviewed Sam after he received the Town Hero Award.
