March 20th is World Water Day every year. According to a report from the United Nations, 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.    小題1:   In most of the past 35 years, it didn't reach the sea.
The Nile in Egypt, running 6, 650 km, is the longest river in the world. 小題2:Now it is down to 2 billion m' or so.  Australia's Murray River reaches the sea only every other year.  One fifth of America's Rio Grande has no water, either.
____小題3:   
Mostly it's damming (筑壩) and global warming that make rivers dry.
____小題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 glacier (冰川) are becoming smaller.   小題5:   Global warming has had certain effects on water sources (源頭). Droughts (干旱) happening around the world make people pay more attention to this fact.
A．Dams hold water to irrigate (灌溉) fields and make power.
B．The source of the Yellow River is drying up because of it.
C．It used to carry 32 billion m' of water a year.
D．How does it happen?
E. Factories pour waste water into rivers directly.
F. Its source on Qinghai-Tibet Plateau is drying up.

文章大意：每年的3月20日是世界水日。根據(jù)美國的一個(gè)報(bào)道，世界上有一半多的主要河流嚴(yán)重缺水或被污染。黃河，世界上第五大河，在過去的35年里，就沒有流到大海里。同意，埃及的尼羅河，世界上最長的河流，由原來每年的32000000000平方米的流量降低到2000000000.等等。是說明原因造成這樣的現(xiàn)象？主要是由于筑壩和全球變暖導(dǎo)致河流干涸。

Happiness is important for everyone. Most people want to be happy, but few know how to find happiness. Money and success alone do not bring lasting happiness. Happiness depends on ourselves. In other words, we make our own happiness. Here are a few ways to help you be happier.
The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future—for example, getting into college or getting a good job-that we fail to enjoy the present. You should enjoy life’s simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have several close friends tend(有……打算) to live happier and healthier lives.
The second secret to leading a happy life is to be active. Many people experience this, dancing or playing a sport. You can forget about your problems, and only think about the activity.
Finally, many people find happiness in helping others. According to studies, people feel good when they volunteer their time to do many meaningful things for other people. If you want to feel happier, do something nice for someone.
Title; 小題1: _
What happiness depends on?
Happiness depends on 小題2:______
小題3: to be happy ,-
To enjoy小題4:_____in life.
To be active.

Conclusion
Happiness is important for everyone and we make happiness by ourselves.

閱讀下列短文，根據(jù)短文中的信息完成文后表格。在答題卡標(biāo)有題號(hào)的橫線上，寫出空缺處所填單詞的正確形式。（每空一詞）
‘USA? Britain? Which country is better to study in?’ We often hear such discussions. As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world.
It’s true that studying abroad can help students develop themselves. Their foreign language skills will be improved and it may be easier to find jobs.
But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language.
Students must also learn to live without parents’ care and deal with all kinds of things they haven’t had to do before, like looking after themselves. There are reports about Chinese students abroad running into an ocean of difficulties and giving up finally. When they have to take care of themselves, it is hard for students to study well.
Finally, studying abroad brings a heavy burden（負(fù)擔(dān)）to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it?
We know that there are many famous people who have achieved success through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there, but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games. So when you wonder which country is better to study in, think again.
