A. Dams hold water to irrigate (灌溉) fields and make power.

B. The source (源頭) of the Yellow River is drying up because of it.

C. It used to carry 32 billion m³ of water a year.

D. How does it happen?

E. Its source on Qinghai-Tibet Plateau (青藏高原) is drying up.

March 22nd is World Water Day every year. According to a report from the United Nations in 2006, more than half of the world’s major rivers have serious water loss and are polluted.

The Yellow River, the world’s fifth longest river, watered some of the oldest farms on earth. But now it has a serious problem.   1   In most of the past 35 years, it didn’t reach the sea.

The Nile in Egypt, running 6, 650 kms, is the longest river in the world.  2   Now it is down to 2 billion m³ or so. Australia’s Murray River reaches the sea only every other year.  One fifth of America’s Rio Grande has no water, either.

  3 

Mostly, it’s damming (筑壩) and global warming that make rivers dry.   4  Now about 45, 000 of them lie across the world’s rivers. They hold back around 15% of the world’s fresh water from running to the sea.

Global warming is making things worse. Warmer weather takes water away. The glaciers (冰川) are becoming smaller.  5   Global warming has had certain effects on water sources. Droughts (干旱) happening around the world make people pay more attention to this fact.

    According to scientists' research, the month in which babies are born could affect them in some ways.

    Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn  Scientists believe many of the differences can be explained by the mother's exposure to sunlight in pregnancy(懷孕).  Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health.

    Vitamin D, called the "sunshine vitamin", is known to help regulate（調(diào)節(jié)） thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health  This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring.

    Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting. He added, "These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth."

1.A baby's season of birth doesn't affect its_______.

    A health              B height              C length of life           D. mind

2. According to the passage,_______ can help people get Vitamin D.

A. enough sleep                              B. enough sunlight   

C fresh air                                        D. suitable seasons

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

    A. People born in spring may not be in good health.

    B. Children born under Aquarius are cleverer than those born under Libra.

    C. Professor Russell Foster is interested in star signs and believes in them

    D. People born in May will live longer than those born in October.

4. What does the passage mainly tell us?

    A. People can know the length of life by star sign.

    B. Women should choose to give birth to children in spring.

    C A child's season of birth has some effect on him or her.

D. Vitamin D is very important to people's health.

任務(wù)型閱讀 ，閱讀下面的材料，根據(jù)其內(nèi)容填空，完成后面的表格。

Playing with friends, going to a party, having a meal in a restaurant or receiving a birthday gift—as a teenager, you go to different places and meet different kinds of people. Everything you do leaves an impression (印象). So manners are very important.

Arriving 30 minutes late for a date may say: “This isn’t that important to me.” Taking a cell phone call while talking to your friend may say: “The caller is more important than the person standing in front of me.” Failing to show thanks to a gift-giver may say: “I don’t like the gift.”

Is that the message you really want to send? Maybe not. You do not want to be rude, but sometimes what you do makes people think you’re impolite.

How can you change that? First, you should know the proper ways to behave around people. We call this manners. Manners are about being honest, respectful (尊重) and considerate (考慮周到的). Good manners show in small things. Start to make your manners better now!

You could start by adding “please” and “thank you” to your vocabulary and avoiding bad language. You could start by holding a door open for someone after you to go through. You could start by showing up on time instead of letting others wait for you.

Start now! Start a new life and start to be a teenager with good manners!
