Name
Date
Vocabulary
genome
nounThe complete set of genetic material present in an organism.
"The mapping of the human genome was completed ahead of schedule."
bioethics
nounThe ethics of medical and biological research and practice.
"Bioethics committees must weigh scientific progress against potential harm."
consent
nounPermission for something to happen, especially informed agreement to medical procedures.
"Informed consent is a cornerstone of ethical medical research."
embryonic
adjectiveRelating to an embryo; in an early stage of development.
"Embryonic stem cell research remains a contentious issue."
euthanasia
nounThe painless killing of a patient suffering from an incurable condition, sometimes called mercy killing.
"The ethics of euthanasia continue to provoke intense debate."
autonomy
nounThe right or condition of self-governance; a patient's right to make decisions about their own care.
"Respect for patient autonomy is a fundamental principle of medical ethics."
transgenic
adjectiveContaining genetic material artificially transferred from another species.
"Transgenic organisms have raised questions about the boundaries of nature."
moratorium
nounA temporary prohibition of an activity, especially by official agreement.
"Several countries have called for a moratorium on human gene editing."
Grammar Focus
Advanced conditional structures: mixed and inverted
Inverted conditionals omit 'if' and invert subject and auxiliary, creating a more formal register. 'Had I known' = 'If I had known'; 'Were she to agree' = 'If she were to agree'; 'Should it transpire' = 'If it should transpire'. These can combine with mixed time references: 'Had scientists not mapped the genome, we would still be unable to identify genetic disorders' (past condition → present result). Inverted forms are common in academic writing, formal speeches, and legal language.
Had the clinical trial been conducted properly, the drug would now be on the market.
Were the committee to approve the research, work could begin immediately.
Should it transpire that the data was falsified, the consequences would be severe.
Had it not been for the moratorium, gene-editing experiments would have proceeded unchecked.
Exercises
Exercise 1
Rewrite each conditional sentence using an inverted form (without 'if').
1. If I had known about the risks, I would never have consented. → about the risks, I would never have consented.
2. If she were to refuse treatment, the doctors would face a dilemma. → treatment, the doctors would face a dilemma.
3. If it should emerge that consent was not obtained, the study will be invalidated. → that consent was not obtained, the study will be invalidated.
4. If the gene therapy had been available then, many lives could have been saved. → available then, many lives could have been saved.
5. If the patient were competent to decide, the situation would be simpler. → competent to decide, the situation would be simpler.
Exercise 2
Select the correct inverted conditional form.
1. ___ the research funding been approved, the project would already be underway.
2. ___ the ethics board to reject the proposal, the team would need to redesign the study.
3. ___ it transpire that the results were fabricated, the university would face serious reputational damage.
Reading
The Ethics of the Threshold
Had the technology for gene editing not advanced so rapidly, the ethical questions surrounding it might have remained theoretical. As it stands, CRISPR-Cas9 has made it possible to alter the human genome with unprecedented precision, and bioethicists find themselves grappling with dilemmas that were once the province of science fiction. Were it possible to eliminate hereditary diseases before birth, should parents be permitted — or even encouraged — to do so? Should it transpire that such interventions carry unforeseen risks, who would bear the responsibility? The principle of patient autonomy suggests that individuals should have the right to make informed decisions about their own genetic material. However, were this right to be extended to decisions about the genetic composition of future generations, it would raise profound questions about consent — for the unborn child cannot consent. Had bioethics committees not imposed moratoriums on certain forms of research, it is conceivable that experiments would have outpaced our capacity for ethical reflection. The challenge is to ensure that scientific progress is guided by robust ethical frameworks, not constrained by them. Were we to fail in this endeavour, the consequences could be irreversible.
1. What ethical problem does the passage identify regarding gene editing and consent?
2. What role have bioethics committees played, according to the passage?
Speaking
Discuss these questions with a partner or your teacher.
Writing
Write a formal paragraph (6–8 sentences) discussing an ethical dilemma related to medical technology. Use at least three inverted conditional structures.
Example: Had organ transplantation not been developed in the twentieth century, countless patients would have died from conditions that are now treatable. Were the supply of donor organs to meet demand, the ethical dilemmas surrounding allocation would be far less acute. Should it become possible to grow organs artificially, the entire framework of transplant ethics would need to be reconsidered.
Answer Key — For Teacher Use
Exercise 1
1. Had I known · 2. Were she to refuse · 3. Should it emerge · 4. Had the gene therapy been · 5. Were the patient
Exercise 2
1. Had · 2. Were · 3. Should
Reading Comprehension
1. The passage argues that extending the right to modify genetic material to decisions about future generations raises consent issues, because an unborn child cannot consent to genetic modifications made on their behalf. · 2. By imposing moratoriums on certain forms of research, bioethics committees have prevented experiments from outpacing society's capacity for ethical reflection.
