A high school in Hiroshima City has been the first to do something with DNA in the world. Its students have won praise not only for doing this research but also for presenting their findings to groups of expert scientists. The school is one of the Super Science High Schools allowed by the Ministry of Education, Culture, Sports, Science, and Technology, where students are given an opportunity to study science at an advanced level. Here, students use the same type of hitech experimental laboratories as those found at universities. In these labs, they conduct experiments and research in new fields of study not found in textbooks. As part of this science course, the students, with the help of Hiroshima University, used a machine called sequencer (音序器), and over the course of a year and a half they succeeded in decoding (解译) the DNA. They then presented their results to academic groups. Achieving a world first might sound very wonderful, but the process of decoding the DNA involved very hard work. The students were also responsible for maintaining the equipment, and they had to read difficult research papers and put in extra study beyond their regular schoolwork.

    "Researchers need to work hard. The work was tiring, but the students worked toward their ambitious goal of achieving a world first. They have a great sense of achievement, and the number of students who hope to become biologists has increased," said Taruma Akinori, who is in charge of the science course.

    In addition to the results being added to the scientific community, the students’ research paper will be translated into English and made available overseas. Moreover, the students have decided to take on a new challenge in DNA decoding.

Which of the following is the most suitable title for the passage?

A. Decoding the blueprint of life

B. Super Science High School

C. More students hoping to become biologists

D. Hi-tech experimental laboratory

Up to a point, their success is due to ______.

A. hi-tech experimental facilities

B. the great pressure their school put on them

C. the increasing number of biologists

D. little interest in their regular school work

The research paper will be put into English in order to ______.

A. become an English textbook   

B. help the students make English friends

C. make the results known by the whole world

D. challenge foreign scientists

The author’s attitude towards those students who have accomplished a world first in DNA decoding is ______.

A. indifferent          B. admiring

C. slighting            D. disappointed

Hi, everyone. To let us get closely to nature and do more exercise, the Committee of our
community will organise the activity. All residents they are interested in farming are invited to
take part the activity. Weather permitted, we’ll ride bike to do some farming this Saturday on a
farm. It is about 5 kilometres far away from our community. You can grow some vegetables,
plant some flowers and fed fish in the lake nearby. You will be trained and guide while
farming. Not only will you enjoy the pleasure of labour and get relaxed, but also you can taste
some fresh produce unless you are willing to. Everyone is welcome to attend!

Bollworms are a traditional threat to cotton crops．Young ones feed on the boll, the part of the

cotton plant that contains the seeds．

A bacterium known as Bt is able to kill bollworms and some other pests．Bt is short form for Bacillus thuringiensis．It was discovered in the early twentieth century．Farmers began using Bt as a natural pesticide（杀虫剂）．

Then，in the 1990s，researchers found a way to grow cotton plants that contain a Bt gene．The genetically modified cotton plant produces toxins that kill bollworms．Farmers around the world are now growing an estimated fourteen million hectares of Bt cotton．

Cotton bollworms also attack other crops．But scientists in China recently reported that Bt cotton may help suppress bollworm in other crops growing nearby．

The study involved crops grown in six provinces of northern China between 1992 and 2008.The study area contained three million hectares of cotton and twenty-two million hectares of corn，peanuts，soybeans and vegetables．

The researchers say the study suggested that Bt cotton not only controls bollworm on the transgenic cotton，but also may reduce its presence on other crops．And that reduction，they say，may decrease the need for insecticide use in general．

But the researchers also pointed out concerns．They say bollworms could develop resistance to the cotton plants designed to resist them．And they noted that insects called mirids have become “key pests” of cotton in China．They said this is because of a decrease in pesticide use made possible by Bt cotton．

The researchers say they do not believe that Bt cotton alone can solve all insect problems．Instead，they say farmers in China should consider it just one part of pest management systems．

44．What is Bt in this passage?

         A．It's a kind of hi-tech invention．      B．It's a natural bacterium．

         C．It's a kind of pest．                    D．It's a man-made pesticide．

45．Bt cotton has all the advantages EXCEPT that ________．

         A．it resists bollworms

         B．it does good to other crops growing around

         C．it reduces the use of insecticide

         D．it helps to develop new insects

46．The underlined word “ones” in the first paragraph refers to ________．

         A．bollworms             B．cotton crops          C．cotton seeds        D．pests

47．From the passage，we can infer ________．

         A．farmers around the world are now growing a large area of Bt cotton

         B．researchers are probably now searching for new ways to solve other cotton problems

         C．bollworms could not exist in Bt cotton any longer

         D．Chinese scientists found the way to grow Bt cotton
