2、ays a strictly practical role.To get a full appreciation of what this means we must turn first to some recent human inventions. Everyone knows that if he shouts near a wall or a mountainside, an echo will come back. The further off this solid obstacle, the longer time it will take for the return of

3、the echo. A sound made by tapping on the main body of a ship will be reflected from the sea bottom, and by measuring the time interval between the taps and the receipt of the echoes the depth of the sea at that point can be calculated. So was born the echo-sounding equipment, now in general use in s

4、hips. Every solid object will reflect a sound, varying according to the size and nature of the object. A shoal of fish will do this. So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish. With experience, and with improved equipment, it is now possible not onl

5、y to locate fish but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo.A few years ago it was found that certain bats emit squeaks (吱吱聲) and by receiving he echoes they could locate and steer clear of obstacles-or locate flying insects on which they feed. This echol

6、ocation in bats is often compared with radar, the principle of which is similar.Text2原文較大改動(dòng)改編Welcome to Faith Radio Online-Simply to Relax,Im Faith.Over the years as Ive sought out ideas,principles and strategies to lifes challenges,Ive come across four simple words that can make living worthwhile.F

13、ome in. Someone will give you an electronic PIN (個(gè)人身份號(hào)碼)to wear. This PIN tells the house who and where you are. The house uses this information to give you whatyou need. When its dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves w

Ifyou get a telephone call, only the nearest telephone rings. Of course, you are also able to tell the house if you want somethin

15、g. There is a home control console (控制臺(tái)), a small machine that turns things on and off around you. The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works

16、 for you because you have the keys. My house works for you because you wear the PIN or hold the console. I believe that ten years from now, most new homes will have the systems that Ive put in my house. Thesystems will probably be even bigger and better than the ones Ive put in today. I like to try

17、new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, How will I live without them?Text2.根據(jù)新華社原稿出題A group of leading scientists on Thursday proposed the launch of an ambitious follow-up to t

18、he 13-year, 3-billion-U.S.-dollar Human Genome Project (HGP), including creating a fully synthetic human genome within 10 years.Called Human Genome Project-Write (HGP-write), the proposal by genome research pioneers such as Jef Boeke and George Church was first revealed two weeks ago, when a secret

19、meeting at Harvard University on this topic triggered debate in the life science community.TIME TO WRITE HUMAN GENOMEThe original Human Genome Project only aimed to read DNAs 3 billion pairs, but Boeke, Church and colleagues declared in the prestigious U.S. journal Science that now is the time to be

20、yond that to write them via chemical synthesis.They argued that the original HGP, which ended nominally completed in 2004, was also once considered controversial by some but now recognized as one of the great feats of exploration, one that has revolutionized science and medicine.According to these s

21、cientists, although technology for sequencing DNA continues to advance rapidly, the capability to construct DNA sequences in cells is mostly limited to a small number of short segments, restricting the ability to manipulate and understand biological systems.Further understanding of genetic blueprint

22、s could come from construction of large, gigabase-sized animal and plant genomes, including the human genome, which would in turn drive development of tools and methods to facilitate large-scale synthesis and editing of genomes, the scientists said.To this end, we propose the Human Genome Project-Wr

23、ite (HGP-write), they wrote. HGP-write will require public involvement and consideration of ethical, legal, and social implications from the start.HGP-WRITE GOALSThe group said they planned to launch HGP-write in 2016 with 100 million dollars in committed support, from public, private, philanthropic

24、, industry, and academic sources from around the world.Total project costs, they said, are difficult to estimate, but would likely be less than the three billion dollars spent by the original HGP.The primary goal of the proposed follow-up, according to the scientists, is to reduce the costs of build

25、ing and testing large genomes, defined as having 0.1 to 100 billion base pairs, in cell lines by over 1000-fold within 10 years.This will include whole-genome engineering of human cell lines and other organisms of agricultural and public health significance, or those needed to interpret human biolog

26、ical functions - gene regulation, genetic diseases, and evolutionary processes, for example.This goal is necessarily ambitious, since building a human genome at todays prices would cost more than the original HGP, they said.This effort should begin with stepping stone projects that will focus on a f

28、ost-efficient vaccine and pharmaceutical development using human cells and organoids.ETHICAL ISSUESIn 2010, genome research pioneer Craig Venter had succeeded in synthesizing the genome of a bacteria known as Mycoplasma mycoides, which consists of 1.08 million base pairs.In 2014, an international te

30、n University bioethicist Laurie Zoloth, who were the first to reveal the secret Harvard meeting, slammed the project as raising ethical issues and moral implications.For example, would it be OK to sequence and then synthesize Einsteins genome? they asked in an article. If so how many Einstein genome
