Earlier this year I traveled to Turkana in Kenya. I was there to take pictures of the “broken food system”.

As a special visitor, I was greeted with songs and dances. The locals used to sing and dance all the time but now Turkana is silent and has been for some years. No one is singing or dancing any more because they have no food, nothing to celebrate. Many of them are surviving on a little corn a day and water, which they can get just every two days.

I met Tede Lokapelo, a local farmer who described the experience of a six-year drought(干旱). Tede used to have 200 goats, but now he has only seven left. He told me that this drought has taught him a hard lesson: It is too difficult to keep animals. He lives on animals. His traditional way of life has been completely destroyed now. Without the food aid(援助) they got, Tede is certain that they would starve because there are no other ways to feed themselves left.

Sadly, the same can be heard in almost any developing country around the world. Almost one billion people go to bed hungry each night. The food system is broken. In Turkana, not enough rain has fallen since 2005. They measure(测量) rainfall not in days or weeks but in minutes. More and more people are being forced to rely on food aid, but people like Tede don’t want food aid. They want to work and develop their country. It’s our responsibility(责任) to change the situation so that they can support themselves.

Drought is impossible to avoid but famine(饥荒) is manmade, and unless enough money is provided to develop a basic infrastructure(基础设施) for people in the area, thousands more lives are sure to be lost.

小题1: Why do people in Turkana no longer sing or dance any more?

A.Because they have no time.

B.Because they are tired of them.

C.Because they are always hungry.

D.Because they have other interesting things to do.小题2:During the drought Tede had experienced, ______of his goats were killed.

A.200

B.193

C.7

D.6小题3: Which of the following is NOT true about Tede Lokapelo?

A.He was a farmer in Kenya.

B.He has never received any food aid.

C.His traditional way of life ha s been changed.

D.He found it hard to raise animals after the drought.小题4:What’s the author’s purpose in writing the text?

A.To show drought is serious in the world.

B.To tell readers the serious situation of food shortage(短缺).

C.To ask more people to give food aid to people in Kenya.

D.To make it clear what is the right way to help people suffering from drought.

数学天才=数学教师? 陈景润是厦门大学数学系的高材生,四年课程他仅学了三年,就以优异的成绩提前毕业分配到北京的一所中学任数学课教师。 他在中学上课不能符合教学常规要求,缺少必要的基本功,稍不注意就把自己研究的课题——数论的内容讲出来,学生们意见很大。学校领导与教师多次提醒他加以改进,但效呆不大。没办法,学校只好在试用期满后劝其回母校,实际上是将他退回母校。 为了谋生,陈景润在福州街头摆了一个小人书摊,没有工商许可证,他就将大学毕业证文凭摆了出来,但仍不忘记:但仍不忘记研究他的猜想。后来母校认为原先对他的分配是一个失误。很可能是对未来数学家的埋没,于是就把他安排在图书馆数学资料室工作——结果他成为了我国著名的数学家。 陈景润是数学天才,但在学校里他做不好数学教师,问题出在哪儿?
