Ai đó làm giúp em bài này với ạ. Em cảm ơn mọi người nhiều
STEP 1 Circle all of the transition signals in the following paragraphs.
STEP 2 Punctuate the transition signals if necessary.
Genetic research has produced both exciting and frightening possibilities. Scientists are now able to create new forms of life in the laboratory due to the development of gene splicing. On the one hand, the ability to create life in the laboratory could greatly benefit mankind. For example, because insulin is very expensive to obtain from natural sources, scientists have developed a method to manufacture it inexpensively in the laboratory. Another beneficial application of gene splicing is in agriculture. Scientists foresee the day when new plants will be developed using nitrogen from the air instead of from fertilizer therefore food production could be increased. In addition, entirely new plants could be developed to feed the world's hungry people. Not everyone is excited about gene splicing however. Some people feel that it could have terrible consequences. A laboratory accident, for example, might cause an epidemic of an unknown disease that could wipe out humanity. As a result of this controversy, the government has made rules to control genetic experiments. Still, many people feel that these rules are not strict enough even though the scientific community may feel that they are too strict enough even though the scientific community may feel that they are too strict.
