The seed vault（种子地窖）

A lot of countries need different kinds of seeds so that they can plant them again． There is an important reason for this， Sometimes plants can't grow in a country because of bad weather or disease， so farmers need new seeds．

You can keep seeds in a "seed vault"． It's a place at a special temperature． The seeds don't grow，but they can live for a long time． Norway has the biggest seed vault in the world ﹣the Svalbard Global Seed Vault﹣and it has seeds from a lot of different countries．

The vault is on the island of Spitsbergen． The island is about one thousand kilometers from the North Pole． It's a very cold place so it's good for seeds． Above the ground， the doorway is small， but inside， the building is huge． You walk down a long corridor （走廊）， which is one hundred and thirty meters inside a mountain．At the end of it， there are three large areas with seeds．

There are about half a million kinds of seeds inside the vault． For example， there are kinds of seeds for rice from Asia and Africa， 32 kinds of seeds for potatoes from Ireland and seeds for different tomatoes from the USA．

The seed vault has space for a lot more seeds． You can put about 2.2 billion（十亿）seeds inside． The seeds can live here for thousands of years because of the cold temperature of ﹣18℃． So in the future， humans can grow any seed they want． In other words， the seed vault is the difference between life and death．

For thousands of years， humans have explored（探索）the Earth． Nowadays， we are exploring space． Astronomers （天文学家） are the modern﹣day explorers，Now， many astronomers are looking for new planets and new places for humans to live in the future． But where do astronomers start looking？

First of all， astronomers look for a star． That's because our own Earth moves around a star（the Sun）． More importantly， it is the correct distance（距离） from the Sun for heat and light． So when astronomers have found the star， they look at the planets around it In recent years，astronomers have found nearly 400 new planets with stars． However， many of these planets are either too near to the star or too far away．

However， if the planet is in a good position， astronomers look for three key things： water， air and rock．Water is important because all life needs water． Humans can drink it and they can also grow plants with water．And plants produce air for humans to breathe and food to eat． Rock on a planet is also important． That's because there is often water under the rock．

After many years of scrutinizing．astronomers have found a planet that is similar to the Earth. It's Gliese 581g and it's near a star. The astronomers think it has water and rock and the average(平均的) temperature is between-310C and -120C. That's cold，but not colder than Antarctica or Arctic Circle, for example, Gliese 581g is bigger than the Earth. A year on Gliese 581g is only 37 Earth days instead of 365. But astronomers do not think there are big differences and some them thing Gliese 581g will be a new Earth. However, Gliese 581g is twenty light years from the Earth.

（1）What do astronomers have to find first before starting to look for a new place for humans to live？　　

A．	new star．
B．	A new planet．
C．	Some heat．
D．	Some light．

（2）What does the rock on a planet tell us？　　

A．	The star is in a right position．
B．	We may discover water under it．
C．	The planet is too near to the Sun．
D．	There can be air around the rock．

（3）What does the underlined word " scrutinizing" mean in the last paragraph？　　

A．	discussing．
B．	waiting．
C．	looking．
D．	traveling．

（4）What's the main idea of the text？　　

A．	Gliese 581g is already a new Earth．
B．	There are planets similar to our Earth．
C．	Water， air and rock are important．
D．	Astronomers are looking for a new Earth．

Students in Kenya are returning for their third term． They begin their school year in January and it is broken up into three terms． In Kenya， in the past， students were not required to attend school and the education was not free， either．

I taugth math, English and physics at Chamasiri Secondary School whiel I was a teacher in Kenya. This school had four classrooms-one for each grade, Form 1, Form 2, Form 3 and Form 4. They are equivalent (对等) to our 9th ,10th ,11th, and 12th grade. Teachers traveled from classroom to classroom instead of the students going from room to room. The Form 1 class had 60 students, Form 2 had 45, Form 3 had 30, and Form 4 about 12 students. The class sizes became smaller as the grades continued on. Why did this happen? Many families were very poor and couldn't afford the school fees(学费).

Most countryside schools in Kenya did not have a lot of money． As a result， there were very few textbooks for the students to use． I had seven math texts for my Form 2 class and 14 for the Form I class． Anything the students needed to know was put up on the blackboard and the students copied it down into their notebooks， The notebooks became the students' textbooks．

Kenyan students study ten different subject areas． Some of the students spend over an hour running home．They do chores at home and hopefully manage to find some time to study before it gets dark． Most families do not have electricity and may not even have candies for their children to study by．

Luckily， Kenyan education has been becoming better and better in the past few years． I'm sure it will have a good future．

A．	The students did not pay the schools．
B．	The schools couldn't afford the textbooks．

（3）Why do some students run home from school？　　

A．	They aren't allowed to stay at school．
B．	They don't like studying in the school．
C．	They hope to have more time to study．
D．	They want to get candles in the stores．
