"Over the years the unthinkable has become thinkable and today we sense we are close to being able to alter human heredity ?#)." These were the words of David Baltimore of the California Institute of Technology, on December 1st, when he opened a three-day meeting in Washington to discuss the morality and use of human gene editing. Dr Baltimore is an old hand at these sorts of discussions, for he was also a participant in the Asilomar conference, in 1975, which brought scientists together to discuss a safe way of using the then-new tcchnology of recombinant DNA, and whose recommendations influenced a generation of biotechnology researchers.

Four decades on, the need for a similar sort of chin-wag has arisen. The International Summit on Human Gene Editing has been held by the national scientific academies of three countries — America, Britain and China. They are particularly concerned about whether gene editing should be used to make heritable changes to the human germ line, something Dr Baltimore described as a deep and troubling question. Like those of Asilomar, the conclusions of this meeting will not be binding. But the hope is that, again like Asilomar, a mixture of common sense and peer pressure will create a world in which scientists are trusted to regulate themselves, rather than having politicians and civil servants do it for them. The meeting is being held against a backdrop of rapid scientific advance, Since 2012 research into a new, easy-to-use editing tool called CRISPR-Cas9 has blossomed. This technique involves a piece of RNA (a chemical messenger, which can be used to recognise a target section of DNA) and an enzyme (酶) called a nuclease that can snip unwanted genes out and paste new ones in.

Public interest was aroused in April, when Chinese scientists announced they had edited genes in non-viable ( 無(wú)活力的) human embryos, and again in November when British researchers said they had successfully treated a one-year-old girl who had leukaemia ( 白血病), using gene-edited T-cells. T-cells are part of the immune system that attack, among other things, tumour cells. The researchers altered T-cells from a healthy donor to encourage them to recognise and kill the patient's cancer, to make them immune to her leukaemia drug, and to ensure they did not attack her healthy cells.

In another recent development, a firm called Edit as Medicine, which is based in Cambridge, Massachusetts, has said it hopes, in 2017, to start human clinical trials of CRISPR-Cas9 as a treatment for a rare genetic form of blindness known as Leber congenital amaurosis (伯氏先天性黑蒙). Though other companies are already testing gene-editing therapies, these employ older, clunkier forms of the technology that seem likely to have less commercial potential. Moreover, researchers at the Broad Institute, also in Cambridge, said this week that they had made changes to CRISPR-Cas9 which greatly reduce the rate of editing errors — one of the main obstacles to the technique's medical use.

On the subject of germ-line editing, Eric Lander, the Broad's head, told the meeting it would be useful only in rare cases and said it might be a good idea to "exercise caution? before making permanent changes to the gene pool. The need for caution is advice that might also be heeded by those pursuing work in animals other than people, and in plants — subjects not being covered by the summit.

1.Which ofthe following is TRUE about CRISPR-Cas9?

A. It has fewer side effects.

B. It can modify human gene.

B. It can protect immune system.

D. It has less commercial potential.

2.The underlined word "chin-wag" in Paragraph 2 can be replaced by______

A. discussion B. negotiation

C. argument D. comparison

3.What can be inferred from the passage?

A.Dr. Baltimore started his research on modiffing gene in 1975.

B. Scientists' opinions about the use of gene editing are consistent.

C. CRISPR-Cas9 has been applied to cure Leber congenital amaurosis.

D. More research should be made before the technology comes into wide use.

4.This passage is most probably a______.

A. science fiction B. scientific report

C. conference summary D. commercial advertisement

Teenagers are especially likely to suffer loneliness. Here are some suggestions for speeding a recovery from loneliness.

Reach out to others, but start small. A smile and a friendly greeting for the student behind you in line at the cafeteria won’t make you best friends. 1. It also can make it easier to interact the next time.

Find a safe place to make connections. If going to the school dance makes you feel like you just don’t belong, try joining a special-interest group. Maybe it’s the drama club or the marching band 2. .

Find other ways of making connections. Lonely people hunger for acceptance and friendship. Sometimes feeling accepted and liked comes more easily when you do something for others. 3. Teach a child in reading. Take notes for a disabled classmate. You might be surprised at the connections you make after reaching out in these ways.

4. Loneliness is an absence of quality friendships, not of a particular quantity of friends. That’s why it’s important to know how to select a friend. The best friendships are those based on similar values and attitudes.

You get what you expect, so expect the best. If you expect others to be friendly, you will behave in similar ways.

5. It goes away as teens learn how to find their way through their social world and connect with others.

A. But it will make you both feel pretty good.

B. So consider becoming a volunteer.

C. Some teens aren’t so adaptable, however.

D. Encourage people to be friendlier to you.

E. Choose the right people.

F. For most young people, loneliness is only temporary.

G. Look for a group that allows you to ease in gradually.

科目：高中英語(yǔ) 來(lái)源：2016屆江蘇省揚(yáng)州市高三上學(xué)期期末考試英語(yǔ)試卷（解析版） 題型：閱讀理解

“There’s no point in talking with you: you don’t understand me. You don’t even know me.” A teen spits these words at a parent, who is hurt and annoyed. How can her own child say these things? She’s worked hard getting to know him, learning to read his feelings from his voice and gestures. How can her own child now say to her, “You don’t know who I really am”?

Nothing shakes a parent’s confidence as much as the starting of a child’s adolescence. The communication that has flowed easily through words, glance and touch becomes a minefield(雷區(qū))

Recent discoveries that the human brain undergoes specific and dramatic development during adolescence offer new “explanations” of teen behavior, particularly of the impulsiveness(沖動(dòng)) of teenagers. During this development, there may be too many synapses(神經(jīng)元突觸) for the brain to work efficiently, the mental capacities of decision-making, judgment and control are not mature until the age of twenty-four.

An old explanation is that anger hormones account for the apparently unreasonable moodiness(情緒化) of teens. Though hormones do play a role in human feelings, the real task of adolescence, and the real cause of the unrest, is the uncertainty of teenagers about who they are, alongside their eagerness to establish a sense of identity.

This involves self-questioning, self-discovery and self-development across a range of issues, including sex, faith, intellect and relationships. A sense of who we are is not a mere luxury; without it we feel worthless. A teen often looks upon his or her friends sa models: “ I don’t know who I am, but I know who he is, I’ll be like him,” is the underlying thought. Parents also become such mirrors: teens want that mirror to reflect back to them the vividness and clarity they themselves do not feel.

Arguments with parents can often be understood in this context. While those common teenager-parent quarrels, which explode every few days, are often over small things such as homework, housework, and respect; a teenager’s real focus is on a parent’s recognition of his maturity and capability and human value. “ No, you can’t go out tonight,” implies that a parent you got your keys?” or “Do you have enough money for the bus?” are questions that can be easily accepted if asked by a concerned friend, but awaken a teen’s own doubts if asked by a parent. Feeling the need to distinguish himself from the kid who can’t remember to take his lunch, his keys or his money, he blames the parent for reminding him of the child-self still living within him. What my research shows is that quarreling witj your teen doesn’t necessarily mean you have a bad relationship. The quality of teenager-parent relationship has several measures.

1.According to the text, teenagers_____________.

A. can fully understand their parents’ feelings

B. need guidance in every aspect of their life

C. may experience a huge mental change

D. know themselves better than their parents do

2.What do we learn from the text?

A. Parents hate talking to their children because they can’t understand them.

B. The brains of teenagers work more efficiently because of the synapses.

C. Hormones are the real causes of unrest and moodiness in teens.

D. What teens really care about is being recognized by their parents.

3.What is implied in the last paragraph?

A. Quarrels between children and parents often involve serious issues.

B. A parent should not ask a child about money.

C. A child wants respect, especially from his or her parents.

D. Quarrels are a sign of a bad relationship.

4.What will probably be written in the following paragraph?

A. Other ways of assessing teenager-parent relationship.

B. The anger and sadness of parents about their teens.

C. How important the friends of teenagers are.

D. When children become mentally mature.

Recently, more and more schools have set up special organizations calling “Waking Up Club”. They aim to encourage students get up early in the morning. A discussion about set up a similar organization in our school is organized by the Student Union last Monday. 120 students took part in it, of which 67 supported it because they believed it would help them develop good habits and make fully use of the morning time. Therefore, 48 students didn’t think it was a good idea. They held that if to get up early or not depends on one’s habit and it is not right to force us to do so. The rest of the students insisted on that everyone should follow their own wishes and their own lifestyles.
