The Peppered Moth, a kind of insect(昆虫), is found in England. It is light brown in colour and likes to settle(栖息) on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.
But with the development of industry(工业) , smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change colour. It became darker as well. Though the change took several years, some scientists soon notice that newly-born moths were a little darker than usual.
A scientist with the name Kettlewell decided to make a careful study of this phenomenon(现象). He marked some of the light moths and some of the darker ones, and set them free in the woods near Bermingham, an industrial city. Later, he recaptured(重新捕获) as many as the marked moths as possible. The results were as follows.
| |
light moths |
darker moths |
| Moths set free |
201 |
601 |
| moths recaptured |
34(16%) |
206(34%) |
Kettlewell's research (研究) was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke and factory pollution.

Twelve years ago, a young traveler named Rhett Butler from San Francisco, California, visited the Sabah rainforest on Malaysian Borneo. In one area of the rainforest, he watched a bird flying through the trees. The beautiful sight left quite an impression on him. But weeks later, back home, Rhett Butler got the news that trees had been cut down in the area he visited.

He often calls on experts for information. For example, he interviewed Alison Jolly, a top experts on lemurs(狐猴).

Your children’s teacher will be providing extra time for test preparation. This school year’s test will be held on January 8 and 9. The test preparation time is open to all students, and we strongly encourage your children to attend.
This year we are changing the time for our test preparation: it will be on Thursday mornings from 8:10 to 8:50. This helps children who ride the bus and cannot stay for the after-school period. It also helps avoid conflicts with after-school activities.
Danielle and Marina will be working with the recent new test takers 6 days on the following Thursdays: 15th, Nov; 29th, Nov; 6th, Dec; 13th, Dec.; 20th, Dec. and 3rd, Jan.
Besides the test preparation lectures on these dates, teachers are already putting test preparation into their usual courses. We are finding that we can help our students to be both skillful and whole-hearted readers and test takers — after all, we all know that the best test preparation is good reading and writing training.
What can you do at home? Again, the best and most effective test preparation for the ELA test is reading and more reading. The research is quite clear — students who do well in the tests are those who are good readers. Reading not only builds reading ability, it also helps build confidence — important for successful test taking! But do discourage your children from spending too much time on books that are too hard or even a bit too hard. Children best develop comprehension skills when they are reading books just right for them (too easy doesn’t hurt here either).
Finally, on Friday, December 7, we will have a morning lecture on the ELA. Please pay attention!The text is mainly about ________.
| A．how teachers will provide more time for test preparation |
| B．the reason why time for test preparation will be changed |
| C．how teachers have put test preparation into their usual courses |
| D．test preparation information that parents should know about |
The time for test preparation has been changed to _________.
| A．make it more convenient for the students to attend |
| B．help the new test-takers have more time to read |
| C．avoid disagreement in time between different years of students |
| D．avoid conflicts between preparation time and the usual courses |
From the passage, we know that ________.
| A．Danielle will help students prepare for different tests |
| B．the school year test will be on a Tuesday |
| C．all the children must take part in the test preparation |
| D．the students can learn how to write well in the test preparation |
Parents should _____ at home.
| A．prepare good meals for their children |
| B．read more books with their children |
| C．ask their children not to spend too much time on reading |
| D．encourage their children to read more books fit for them |
Why did the school encourage all the students to take part in the test preparation?
| A．Test preparation is what they always do. |
| B．The students will learn what will be included in the final exam. |
| C．Test preparation helps students to be more interested in reading and confident. |
| D．The test is a long way off and there are better things to do. |

I suppose that having been brought up in the countryside and close to animals，it wasn’t remarkable(不平常的)when I decided to become a vet(兽医)．Luckily I was also good at all the necessary science subjects. So after the college entrance examination I found myself at a veterinary college，training to look after animals in all kinds of situations. I hoped that I would be able to work in the research field so that I could find cures for animal diseases.
Much to my surprise，I found public health care was a very important aspect of my course. This is an area of animal medicine where a vet’s work has many things in common with the work of a doctor of human diseases. I particularly liked it because I recognized that the study of animal diseases can help human medicine. As we know，many infectious diseases come from animals—including SARS and bird flu.
Some of the infections have only been understood after carefully analytical work in labs by animal doctors. They helped identify the animal source for diseases such as SARS. They were also the first to identify various kinds of viruses. Sometimes vets are also able to suggest a cure for human illnesses. When I found this out I was determined to make public health medicine my chosen career.
After graduation，I applied for a job in public health. Soon I found myself concerned with the problem of bird flu. This is an illness that attacks birds，but humans can catch the disease if they are in close contact with infected birds. Though the job is dangerous，it makes me proud that vets and other animal disease researchers are in the front line helping to fight these unknown human diseases

| A．it was both important and interesting |
