Do you know why different animals or pests(害虫) have their special colors? Colors in them seem to be mainly used to    1   themselves.

But as the harvest time comes, locusts change into the same brown color    5  crops have. Some other pests whose colors are   6   plants are easily found and eaten by   7  . So they have to hide themselves for lives and appear only   8  .
If you    9 animals’ life, you’ll find the main use of colors is to protect    10  . Bears, lions and other animals  11  quietly through forests. They cannot be easily seen by hunters   12  their colors are much like the trees.
Colors are useful not only on the land, but also in the   13 . A kind of fish can   14  a kind of black liquid(液体) when they face danger. The liquid spreads over quickly, so they cannot be found by their enemies and can quickly swim away. That is   15  they can live safely though they are not strong at all. So colors are really useful to animals.

Homesick is a compound (复合的) word made up of “home” and “sick”. You know
  1  each word means on its own, of course. But think about what the words mean when they are   2  together. “Homesick” means “Thinking of home, unhappy away from home.” In other words, it means “sick for home”.
  Now think for a minute   3  the word SEASICK. If you change the word “home” in the definition (定义) to the word “sea”, would the definition  4  “seasick” ? Does seasick mean “thinking of sea, unhappy away from sea”? It means something quite  5 . Seasick means “made sick by the only place where you are on the sea.” It means “sick because of the sea.” When you are homesick, the only place you want to be is at home. When you are seasick, the   6  place you want to be is at sea.
  Have you ever   7  a person being heartsick? Heartsick does not mean that something is wrong with a person’s heart. People are heartsick when they are   8 down deep inside as if (好像) their hearts are broken.
   And so, when you are carsick, you are “made sick by the movement of a car on the road.” You are sick because of the car, not sick for it.
You can see, then, that   9  compound words are what they seem at first glance (一瞥). Think about the compound words, such as handshake and   10 . Perhaps you may write definitions for them. It must be helpful to know something like this in your English study.

Is learning a foreign language ever easy? Yes. If you are five and move to another country, you will quickly pick up the language. But what about for the rest of us who are no longer five, and need to be polite when traveling for business or for pleasure? I think that answer is also yes. Language learning can be easy if you don’t want or need to learn too much.
The key to successful language learning in my mind is not to set the goal too high. It is rather like running. Even if you run twice a week, you don’t necessarily want to be able to run a marathon (马拉松). You might just want to keep a level of fitness. I think the same can be true for language learning.
Let’s get back to the goal. If you decide to learn ten words in a foreign language before visiting the country, you know that you will be sure to do this. However, if you decide to talk to people with great fluency (流利), unless you are quite a talented person, you will probably fail and give up in half-way.
It is also far easier to start learning a foreign language than to finish. In other words, the better you are, the slower it can be to improve, because you will not be able to move further because of grammar, making sentences, learning less common words, etc. If you are only trying to learn a few foreign words and sentences, you will enjoy faster progress, have more fun, and won’t have to spend too much time.
The idea of learning only a few hundred words in a language, and then stopping, isn’t the usual way to language learning, but it can be a very meaningful and enjoyable activity.
小题1:In the writer’s opinion, it is easy for adults to learn English if _______.
A.they are especially talented people
B.they don’t want or need to learn too much
C.they have to spend a lot of time on it
D.they have a chance to go abroad
小题2:The writer believes that if you want to be good at a foreign language, you will probably _______.
A.forget your own goals
B.become a talented language learner
C.get tired of learning it
D.reach your learning goal
小题3:The best title of this passage would be _______.
A.Easy Language Learning B.Hard Language Learning
C.Fluency in a Foreign Language D.A way of Language Learning

I know what you’re thinking: pizza? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to.
I know lots of women who skip (跳过) breakfast, and they have a lot of different excuses for doing it. Some say they don’t have time. Others think they’re “saving” calories, still others just don’t like breakfast food.
But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R, D, who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded(装填) with vegetables, and you just eat one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating (吃得过多) later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of getting weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers — it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow.” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body get the fat-burning effects.
小题1:The word “leftovers” in Paragraph 1 probably means_______.
A.food left after a meal B.things left undone
C.meals made of vegetablesD.pizza topped with fruit
小题2:What can we infer from the text?
A.Working women usually have breakfast in a hurry.
B.Many people have wrong ideas about breakfast.
C.There are some easy ways of losing weight.
D.Eating vegetables helps save energy.
小题3:According to the last paragraph, it is important to_______.
A.be careful about what you eatB.eat calorie-controlled food
C.heat up food before eating itD.eat something for breakfast
小题4:The text is written mainly for those_______.
A.who want to lose weightB.who go to work early
C.who stay up lateD.who eat before sleep
