New genetic analysis has revealed that many Amazon tree species are likely to survive human-made climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out. A study,   1  in the latest edition of Ecology and Evolution, reveals the   2  age of some Amazonian tree species -- more than 8 million years -- and   3  shows that they have survived previous periods as warm as many of the global warming imagined periods   4  for the year 2100.

The authors write that, having survived warm periods in the past, the trees will   5  survive future warming, provided there are no other major environmental changes.   6  extreme droughts and forest fires will impact Amazonia as temperatures   7 , the trees will stand the direct impact of higher temperatures. The authors   8  that as well as reducing greenhouse gas emissions to minimize the risk of drought and fire, conservation policy should remain   9  on preventing deforestation（采伐森林）for agriculture and mining.

The study disagrees with other recent researches which predicted tree species’ extinctions   10  relatively small increases in global average air temperatures.

Study co-author Dr Simon Lewis (UCL Geography) said the   11  were good news for Amazon tree species, but warned that drought and over-exploitation of the forest remained major   12  to the Amazon’s future.

Dr Lewis said: “The past cannot be compared directly with the future. while tree species seem likely to   13  higher air temperatures than today, the Amazon forest is being transformed for agriculture and   14 , and what remains is being degraded by logging, and increasingly split up by fields and roads.

“Species will not move as freely in today’s Amazon as they did in previous warm periods, when there was no human   15 . Similarly, today’s climate change is extremely fast, making comparisons with slower changes in the past   16 .”

“With a clearer   17  of the relative risks to the Amazon forest, we   18  that direct human impacts -- such as forest clearances for agriculture or mining -- should remain a key point of conservation policy. We also need more aggressive   19  to reduce greenhouse gas emissions in order to make minimum the risk of drought and fire impacts and   20  the future of most Amazon tree species.”

I take the firm position that parents do not owe their children a college education. If they can  __1  it, they can certainly send them to the best universities. But they must not feel guilty if they can’t. If the children really want to go, they’ll find a   2   out. There are plenty of loans（货款）and scholarships for the bright and   3  ones who can’t afford to pay.

When children grow up and want to get  married, their parents do not owe them a down payment on a house. They do not have the   4  to baby-sit their grandchildren. If they want to do it,it must be considered a(n)   5  not an obligation（责任，义务）.

Do parents owe their children anything? Yes,they owe them a great deal.

One of their obligations is to give their children personal   6  .A child who is constantly made to feel stupid and unworthy, constantly  7  to brighter brothers, sisters, or cousins will become so  _8_ , so afraid of failing that he（or she）won’t try at all .Of course they should be __9__ corrected when they do wrong, but it’s often better to let children learn their mistakes by themselves in time.All our parents should do is to trust them, respect them, tolerate（宽容）them and give them chances to try and fail.They must learn to stand   10  .When criticisms（批评）are really needed,they should be  11 with praises,with a smile and a kiss.That is the way children learn.

Parents owe their children a set of solid values around which to build their lives.This means teaching them to  12 the rights and opinions of others;it means being respectful to elders,to teachers,and to the law.The best way to teach such values is by  13  .A child who is lied to will lie.A child who sees no laughter and no love in the home will have   14  laughing and loving.

No child asks to be  15  .If you bring a life into the world,you owe the child something.

A couple were having a wedding All of their friends and family came to see the lovely  1 and all had a wonderful time. The bride was  2  in her white wedding gown and the groom was very handsome .Everyone could tell that the  3  they had for each other was true

A few months later ,the wife came to the husband with a 4 ,“Each of us will write a list of things we find a bit  5  with the other person ,Then ,we can tale about how we can  6 them and make our lives happier”The husband  7 ,So they went to think of the things that annoyed them about the other

The next morning ,at the breakfast table ,they decided they would go over their  8

“I’ll start ”said the wife ,She  9  her list , It had many items on it ,enough to fill three pages , As she started reading the list of the little annoyances ,she noticed  10  were starting to appear in her husband’s eyes.

“What’s wrong?”she asked “Nothing,”the husband replied ,“11 reading your list,”

The wife continued to read until she had read all three  12 to her hushand.

“Now, It’s your  13 and then we’ll talk about the things on both of our lists,”she said happily

 14  the husband stated，“I don’t have anything on my list , I shink you are  15 the way that you are , I don’t want you to change anything for me , I wouldn’t want to try and  16 anything about you.”

The wife ,  17 by his honesty and the depth of his love for her and his  18  of her,turned her head and wept.

In lire, there are enough times when we are disappointed. Depressed and annoyed , We don’t really have to go  19 them. We have a wonderful world that is rull of beauty ,light and promist Ehy not see the  20  things before us?
