Lichens (地衣) are difficult to see. They don’t move. They often mix into the living place. You might not even recognize one if you are looking right at it.

Lichens live on rocks, branches, houses, and even metal street signs. You can find these colorful organisms (微生物) almost everywhere — from deserts to rainforests, and from Antarctica to Africa. They’ve traveled in outer space, and some scientists think there might even be lichens on Mars.

What you probably don’t realize is that a lichen is more than a single thing. It includes two different types of living organisms: a fungus (菌类) and an alga (藻类). Neither of these organisms is a plant, so the lichen isn’t a plant either.

Through photosynthesis (光合作用), the alga gets the sun’s energy to make food for the fungus, which is the place for the alga to live in. However, the alga cannot leave the fungus.

Around the world, scientists have found tens of thousands of types of lichens. Many may not even have been discovered yet. As scientists continue to find new kinds of lichens, they are also working to understand how they are connected to one another. By putting together a lichen family tree, they hope to understand why so many different types of lichens have grown in so many places around the world.

Many researchers are trying to understand basic facts about the organisms and their connections. Researchers are also using lichens to examine the health of the environment.

What do we know about lichens according to the passage?

A. They will die if they leave Earth.

B. There are more lichens than plants on Earth.

C. They look similar to the environment around them.

A. The way lichens live.

C. The way lichens work as organisms.

D. The family tree of lichens.

A. To understand basic facts about them.

B. To creat a lichen family tree.

C. To understand how lichens are related to each other.

D. To understand why lichens can live in different places.

A. lichens can be used to better understand the environment

B. lichens don’t have any differences in colors or sizes

Of all my teachers, Mr. Brown is the one who impresses me mostly. Mr. Brown teaches us physics. Though he is in late forties, he looks very young for his age. And he is one of the most popular teachers in our school. Comparing with other teachers, he pays much attention to his way of teaching. He tries various ways make his classes lively and interesting. In his opinion, we should not only know “what”, but also understand “why”. So, instead of giving us answers immediately, he encourages us to think of ourselves whenever he puts forward some questions. Under his help, we’ve learned how to analyze and settle physical problems. How a wonderful world of “why” he leads us to! He is so inspiring a teacher that we all admire.

 

If you are having trouble falling asleep, you are in good company. About 65% of Americans said they have sleeping problems a few nights each week, according to a recent study by the National Sleep Foundation. Sleeping too little can lead to a higher risk of becoming fat and getting depressed(沮丧的). But before you go to a doctor for advice, it is worth examining your sleeping habits one more time. Some of your favorite evening habits may have something to do with the sleeping problems.

Setting a Bright Alarm Clock

     The light of your bright alarm clock can prevent you from falling asleep. You can make your room as dark as possible. Cover the bright numbers with a book or consider buying a small travel clock. Your cellphone alarm may also do the trick.

Counting Sheep

When you just can’t fall asleep, it’s useless to stay in bed to count sheep. If you’ve been trying to fall asleep for more than 30 minutes, the National Sleep Foundation suggests you get up to do some reading or watch TV for a while. Such activities will make you sleepy. Before you know it, you’ll be going back to bed really tired.

3. Exercising Late at Night?

       Daytime workouts(锻炼) will keep you full of energy for hours. That’s why you don’t want to exercise within three hours of hitting the sack. Fierce(剧烈的)  physical activity raise your body temperature and pumps your energy level—both are bad for a good night’s sleep.

What can we learn from the first sentence of the passage?

    A. It’s not good to fail to fall asleep at night.

    B. People in a good company often have sleeping problems.

    C. There are many people who have sleeping problems.

    D. You should find someone to talk to if you can’t fall asleep.

The town I live in is about to put cameras at all traffic lights to catch people who run red lights．It   36   me of how many people I’ve seen who take the yellow light as a   37   to go faster．I also can’t understand why people don’t move when the traffic light has turned green．Above all, there are those   38   situations in which someone doesn’t even   39   that the light turns red, and just keeps going．That is why so many   40   happen! All these situations make me   41__    the purpose of traffic lights．

         42   , it’s even more frightening to imagine letting people make their own decisions at   __43   crossroads．Do the biggest cars get to go first? Who decides who goes next? So I guess I do like the idea of a system to   44   traffic．And I’ll do my best to   45   the traffic rules: to go, to be cautious, and to stop when I’m   46   to．

       It occurs to me that my   47   have done much the same for me   48   teaching me how to live．They have given me many   49   lights: to get along well with others, to listen and talk to them, to help others, and to   50   with joy and purpose．They have also given me some red lights   51   my life goes astray（误入歧途）: not to be greedy, to keep my temper, and to control my desires．And there   52   have been some yellow caution lights: to watch how much I drink, to keep control of my behavior, and to   53    school regularly and work hard．

       If I obey these rules, my life will be as   54   as it can be．Just as I’m wise to pay attention to the traffic lights when I’m walking across the street, I’m wise to pay attention to the“   55__ signals” given to me by my parents．
