Not long ago, an airplane was flying over New Zealand. There was a television camera crew on board. Suddenly, out in the night sky, a bright sphere (球體) came into view. Everyone on board saw it and everyone though, "UFO"-Unidentified Flying Object. The camera crew went into action and started filming. That week people all over the world saw the film of this mysterious light on their television screens. What was it? Was it a spaceship full of visitors from another planet? The captain of the aeroplane and the film crew believed it was. Other observers had many different explanations. Some said it was Venus (金星). Others said it was just a trick of light.
An air traffic controller also saw it on his radar screen. He thought that a flock of birds was causing dots on his radar screen when the "UFO" appeared.
Most astronomers now believe that what these people saw was almost certainly the planet Venus. At that time of year it is very bright and easy to see. And from a moving aeroplane it can appear to be moving fast. So far there is no proof that UFOs or spaceships from other planets do exist. These years investigators of UFOs have investigated thousands of sighting-or occasions when people said they saw a UFO. Ninety per cent of these turned out to have a simple explanation.
However, it’s good idea to keep an open mind. Scientists in some countries are trying to persuade their governments to help them study UFOs. And they are planning to cooperate inter-nationally on reporting and investigating sightings of UFOs.
After all, it is quite possible that there is life out there in the universe. And if something is alive, it is quite possible that it will come to visit us.

Passage 1
In recent years, scientific and technological developments have drastically changed human life on our planet, as well as our views both of ourselves as individuals in society and of the universe as a whole. Maybe one of the most profound developments of the last decade is the discovery of recombinant DNA technology, which allows scientists to introduce genetic (遺傳學的) material (or genes) from one organism into another. In its simplest form, the technology requires the isolation of a piece of DNA, either directly from the DNA of the organism under study, or artificially synthesized from an DNA. This piece of DNA is then ligated (結(jié)扎) to a fragment of bacterial DNA which has the capacity to replicate (復制) itself independently. The recombinant molecule thus produced can be introduced into the common intestinal (內(nèi)部的) bacterium Escherishchia coli, which can be grown in very large amounts in synthetic media. Under proper conditions, the foreign gene will not only replicate in the bacteria, but also express itself, through the process of transcription and translation, to give rise to large amounts of the specific protein coded by the foreign gene.
The technology has already been successfully applied to the production of several therapeutically (療法的) important biomolecules, such as, growth hormones, interferon, insulin.
Many other important applications are under detailed investigation in laboratories throughout the world.
21. Recombinant DNA technology consists primarily of ____________.
○A. producing several therapeutically important biomolecules
○B(yǎng). giving rise to large amounts of protein
○C. introducing genetic material from one organism into another
○D. using a viral enzyme called reverse transcriptase
22. Recombinant DNA technology has been used in the production of all of the following biomolecules except ___________.
○A. growth hormones
○B(yǎng). Escherishchia coli
○C. interferon
○D. insulin
23. Which of the following is not true?
○A. The foreign gene will replicate in the bacteria, but it will not express itself through transcription and translation.
○B(yǎng). The bacterium Escherishchia coli can be grown in large amounts in synthetic media.
○C. Research continues in an effort to find other uses for this technology.
○D. Recombinant DNA technology is a recent development.
24. Expression of a gene in Escherishchia coli requires ________.
○A. the viral enzyme reverse transcriptase
○B(yǎng). the processes of transcription and translation
○C. production of insulin and other biomolecules
○D. that the bacteria be grown in a synthetic media
25. The term recombinant is used because ___________.
○A. by ligation, a recombinant molecule is produced, which has the capacity of replication
○B(yǎng). the technique requires the combination of several types of technology
○C. by ligation, a recombinant protein is produced, part of whose amino acids come from different organism
○D. Escherishchia coli is a recombinant organism
