Research on embryonic stem cells (胚胎干细胞) is debatable because it requires the destruction of live human embryos.

Supporters find it easy to minimize the significance of this fact because the embryos are only a few days old—nothing more than “blastocysts (胚泡)”.

But if it’s OK to destroy 5-day-old embryos to further scientific inquiry, is it OK to destroy embryos that are five weeks old? Five months? Eight months? Science can’t answer that question.

You don’t have to be part of the pro-life group to have concerns about this kind of scientific research. James Thomson, the University of Wisconsin biologist has said, “If human embryonic stem cell research does not make you at least a little bit uncomfortable, you have not thought about it enough.” However, the president’s new order suggests we should not think too much.

Recently, supporters of embryonic stem cell research called on president to allow experiments using “surplus (多余的)” fifty frozen embryos in fertility clinics, arguing that they would be disposed of anyway. But Obama didn’t limit his new policy to these fertilized eggs.

On the contrary, he left open the possibility of funding studies using embryos created specifically so their cells can be harvested. He did, however, reject another option. “We will ensure,” he said, “that our government never open the door to the use of cloning for human reproduction. It is dangerous, profoundly wrong and has no place in our society, or any society.”

But this position is hard to square with his claimed approach. On one hand, the president says his policy is “about letting scientists do their jobs, free from pressure”. On the other, he will use pressure to keep them from doing reproductive cloning.

What this policy means is simple: It may be permissible for scientists to create cloned embryos and kill them. It’s not permissible to create cloned embryos and let them live. Their cells may be used for our benefit, but not for their own.

It’s the policy that is risky not just to days-old human embryos. The rest of us are sure to receive important medical benefits from this research one day. But we may lose something even more important in a moral sense.

1.It’s implied in the fourth paragraph that pro-life group ________.

A. support the research on embryonic stem cells

B. don’t agree with any kind of scientific research

C. agree with James Thomson’s opinion

D. rarely think of the consequences of embryonic stem cell research

2.The underlined phrase “square with” in the passage is closest in meaning to ________.

A. find a square tool for                B. be in line with

C. quarrel with                            D. pay off

3.Which of the following statement is TRUE according to the passage?

A. The author thinks there’s a big difference between a 5-day embryo and a 8-month embryo.

B. In Obama’s policy, embryonic researchers can only use surplus embryos in fertility clinics.

C. President Obama hasn’t expressed his attitude toward human reproductive cloning.

D. The research on embryonic stem cells may bring people medical benefits in the future.

4.The author thinks the policy is worrying because ______.

A. the research is against the law

B. we may suffer morally for the research

C. scientists are not really working without pressure

D. ban on human cloning is in the long run harmful to human development

Pets provide an unconditional love that requires very little on the part of the human.

Animals are so special to those of us who love them. We miss them when they are no longer with us. We grieve (哀悼) for them in ways which are just the same as grieving for a human loved one.

Whether the end comes through old age, illness, or sudden death, the death of a pet can cause enormous feelings of sorrow, guilt, and loneliness for children and adults alike, as the animal was considered a family member, a child's favoured playmate, or an older person's loyal and faithful companion.

Some people don't want a pet because they do die! It's understandable to be unwilling to expose yourself to death but, at the same time, we become immeasurably more human because our animals die. When we live with animals we're more in step with the rhythms of the planet from day to night and from season to season because our companions make us more aware of the changes around us. Our companion animals teach us about the simple gifts of a beautiful day, a good meal and a gentle touch.

The death of a pet can make us struggle with our belief structure－a natural part of the grieving period. Whether grieving an animal or human, we question our beliefs and many people find their belief structure becomes stronger when they ask themselves hard questions. Others find a new way of acceptance.

And we learn from our animals. Animals aren't afraid to die; they show us that the end of life can be faced without fear. They can teach us to accept death as an opening for love and wonder.

Allow yourself to grieve in whatever way is appropriate for you. The loss of a pet is real grief and causes us to travel through the stages of grief－denial, anger, depression, guilt, and acceptance. These stages must be lived through for the mourning to allow full healing.

1. According to the passage, the reason why some people don’t want a pet may be that ________.

A. animals may change our belief structure

B. animals are so special for those who love them

C. pets can never escape from death which makes people sad

D. pets only provide people with love but never ask for return

2.The underlined sentence in paragraph 4 probably means ________.

A. the animals’ death is unacceptable for their owners

B. the animals’ death may arouse their true feelings inside

C. the animals’ death may expose people to the changes in life

D. the animals’ death is more understandable than human’s death

3.According to the passage, we can infer that ________.

A. pets can give us some gifts when they have a good meal

B. pets are so selfless and brave that all the people love them

C. people can never accept the death of pets or the one they love

D. people may go through several stages before they can accept the death of a pet

4.What’s the attitude of the author towards grieving a pet?

A. Neutral.         B. Negative.            C. Positive.            D. Critical.
