Scientists in California and Virginia will try to decode

genetic makeup of two plant-destroying microbes, including 【M1】______

one blaming for killing tens of thousands of oak trees along the 【M2】______

West Coast.

Backed by ＄4 million in federal grants, the scientists hope

to sequence the genomes of the two species of Phytophthora.

The most notorious of the pair is P. ramorum, that causes sudden【M3】______

oak death syndrome.

With the genomes in hand, scientists expect to develop

the mean to track, detect and, eventually, treat both diseases.【M4】______

P. ramorum has killed tens of thousands of black oak,

coast live oak and tan oak trees in northern California and

southern Oregon as it first appeared in 1995. This year, 【M5】______

scientists invented coast redwoods and Douglas fir also 【M6】______

are susceptible, as is at least 14 other plant species. 【M7】______

At the same time, scientists at the Walnut Creek laboratory

and at the Virginia Bioinformatics Institute in Blacksburg will

sequence the genome of P. sojae, a related microbe

responsible soy rot, which is estimated to cause ＄1 billion in 【M8】______

damages to soy Bean crops worldwide. Both sequences will be

free available on the Internet once completed. 【M9】______

The two species of funguslike organisms are closely

related to algae. Among their relatives is P. infestans, the microbe

responsible for the failure of potato crops in Ireland in the

19th century and the resulting famine. The name

Phytophthora means "plant devourer" in Greece. 【M10】______

【M1】

ys.科学家了解人类的一种方法是研究如老鼠、猴子这样的动物。The scientists in this laboratory are

experimenting on mice. They are studying the relationship between diet and health. At this time, over one hundred experiments are being done in this laboratory.

In one of these experiments, the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy diet. But the amount of food that each group is receiving is different. The first group is eating one cup of food each day, the second group is eating two cups, and the third group of mice is eating three cups.

After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Most of the day, they are running, playing with one another, and using the equipment in their cages. Also, they are living longer. Mice usually live for two years. Most of the mice in this group are still alive after three years.

The second group of mice is normal weight. They are healthy, too. They are active, but not as active as the thinner mice. But they are only living about two years, not the three years or more of the thinner mice.

The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. They are not very active. These mice are living longer than the scientists thought - about a year and a half. But they aren't as healthy. They're sick more often than the other two groups.

A：T

B：F

(2)、The first two groups are receiving the most food.

nds, words, a system of word order, and grammar.Word order is more important in English than in some other languages.The sound system is very important in Chinese and in many African languages.

Language is always changing.The earliest known languages had complicated grammar but a small, limited vocabulary.Over the centuries, the grammar changed, and the vocabulary grew.For example, the English and Spanish people who came to America during the sixteenth and seventeenth centuries gave names to all the new plants and animals they found.In this way, hundreds of new words were introduced into English and Spanish vocabularies.Today life is changing very fast, and language is changing fast, too.

There are several major language families in the world.Some scientists say there are nine main families, but other scientists divide them differently.The languages in each family are related, and scientists think that they came from the same parent language.

We learn our own languages by listening and copying.We do this without studying or thinking about it.But learning a foreign language takes a lot of study and practice.

(1).What do all languages in the world have？

A.Complicated vocabularies

B.Single grammar

C.Large vocabularies
