Do you have trouble getting started in the morning? Do you have problems learning early in the day? If you do, you are not alone, __小题1:_ They learn better at night than they do in the morning.
To investigate when cockroaches(蟑螂) learn best, researchers at Vanderbill University tested the insects for which odor(peppermint 薄荷 or vanilla 香草) they preferred. Most cockroaches preferred the smell of vanilla to that of peppermint at all times. _小题2:_ Therefore, the scientists trained the cockroaches to prefer the peppermint smell by rewarding the insects with a taste of sugar water when they approached a peppermint smell. _小题3:__
When the cockroaches were trained at night, they remembered the new associations(peppermint=sugar water; vanilla=salt water) for up to 48 hours. However, if the cockroaches were trained in the morning, they quickly forgot which smell went with which water. __小题4:_
So, cockroaches learn better at night than they do in the morning. _小题5:_ Because of this, it is likely that information they gather at night will be more useful to them. These experiments provide some clues about the interactions between body rhythms, learning and memory.
A.When these insects moved toward a vanilla smell, on the other hand, they were punished with a taste of salt.
B.This result thus shows that the time when they were trained decided the effect of their learning.
C.They are often more active and tend to search for food during the night.
D.They were also found to like sugar water, but not salt water.
E.Cockroaches have the same problem!
F.But they prefer warm conditions found within buildings.
G.Pest species adapt easily to their environment.

Healthy Relationship Tips
Healthy relationships are effortless, if both the people involved take equal effort to maintain it. Here are a few healthy relationship tips to help you build the dream of your life.
小题1:Communication is an art of putting your thoughts into words, so that they are exactly understood by the opposite person. Communication does not mean going on talking unnecessarily. This is the first mistake that couples make. One person in the relationship assumes the role of talker and the other becomes the listener. Their roles remain so forever. The talker forgets to listen and the listener becomes used to listening and not reacting. If your partner takes time to open up, help them out by asking questions. So hear them out and give proper reactions. You will obtain the benefits of a healthy relationship through increased confidence in both of you to open up and hear things out.
小题2:Regular conversations take the form of heated arguments amongst many couples. Understand that not every statement needs a reaction. Maybe a certain reaction may lead to an argument with your partner. Just agree with whatever it is and there will be no harm done. Try and reach a mutual(相互的)agreement. If that’s not possible leave the topic for later. If you give it time, maybe both of you will be able to think about it rationally.
小题3:Every single day is a blessing. Each moment with your partner is a moment to learn something new and discover the finer nuances(细微差别)of your relationships. Each one of us keeps changing every day, the circumstances around us change every day and with that our attitude also needs to change. The same applies when you are living with a person. Learning every day and taking every day as a challenge will help you perfect healthy relationship tips.
小题4:This tip is especially meant for couples with children on how to maintain healthy relationships. After a certain period, couples complain about romance being lost. To keep your relationship healthy, take some time out from your day-to-day routines to spend some quality time with your partner. This can be done as dinners, indulging in outdoor activities or just hanging out at a coffee shop like old times.
小题5:Respect has to be earned. It can be earned only if you learn to respect. Often, one of the partners plays the role of a dictator to give orders, while the other simply follows. Both sides involved are equally responsible for this mistake. Learn to respect each other and understand that both of you are equally responsible for the relationship.
Creating a healthy relationship takes equal effort from both sides. Sharing, caring, being apologetic, forgiving and having realistic expectations are some of the important ingredients to the recipe of a healthy relationship.

阅读下列短文并根据所读内容在文章后表格中的空格里填入最恰当的单词,每空格1词(共10个小题;每小题1分,满分10分)
Zebras have their own bug repellent(驱虫剂)?
Eww bugs! They are so annoying! We humans are lucky that we can apply repellents to avoid nasty bites. But what’s an animal to do? They have no choice but to spend their days shooing them off with their tails, unless, of course, they are zebras, who apparently have their own automatic repellent--- their striped skin!
Scientists had originally thought that the reason why the animal had developed the black and white lines was to help protect itself from predators in the African savannah, because the stripes make it difficult to single out one zebra that is traveling with a herd.While that may be true, the theory has never been tested or proven. Now the experts have another---that the stripes have evolved to repel the annoying horse flies that not only feed off their blood, but also, transmit dangerous germs into the bodies of these innocent animals.
The study was performed by a team of Swedish scientists. One of the clues that got them thinking along these lines was the fact that darker horses got bitten more often than light-colored or white ones.
The fact that zebras are born black and only develop strips as they grow older made the scientists theorize that the stripes may be something the animals have developed to make themselves less attractive to flies.
To test if this may be the case, they painted some boards at a horse-infested horse farm in Budapest with patterns of black and white stripes of varying widths and applied a layer of glue on them. What they noticed was that the places where the black and white stripes were at their narrowest (similar to what zebras have) attracted the fewest flies. They achieved similar results when they painted horses with black and white zebra-like stripes.
While the research are not sure why this may be the case, they believe it may be something to do with the way insects operate---horseflies are attracted to horizontally polarized light(偏振光); since white does not reflect it, white horses are luckier than black ones. But zebras seem to be the luckiest of all. When the researchers measured the polarized light reflected from real zebra skins, they found that it matched light patterns that were the least attractive to horseflies.
While this theory does make logical sense, nobody is 100 percent sure that it is really true, given that it has never been tested on a real zebra. If it is true, it does raise the question of why a horse, a close relative of the zebra has failed to develop stripes. The researchers believe that this could be because there are more horseflies in Africa, where zebras reside, then anywhere else in the world.
