    Layla and her family were driving to the town park. It was a hot day. She wanted to swim in the lake. As they got out of the car, Layla saw {#blank#}1{#/blank#} (she) friends.

    "Let's go into the water!" she called. All the kids jumped in {#blank#}2{#/blank#} (happy).

    Layla always has fun at the park. In spring, Layla's dad often takes her fishing in {#blank#}3{#/blank#}(冠词) lake. They usually go early in the morning. The lake water is still (平静的). It is different {#blank#}4{#/blank#} (介词) the river, which has water that runs by

    In summer, {#blank#}5{#/blank#} (family) have picnics near the lake. The kids play and swim in the lake.

    In the morning of autumn, the lake has fog (雾) over it.

The water vapor(水蒸汽) in the air gets cool. It {#blank#}8{#/blank#} (become) small drops of water (水珠). We can see those drops of water hang in the air as fog.

    Layla loves winter at the park too. The cold {#blank#}9{#/blank#} (temperature) turn the water into ice. Many people go skating on the ice.

    The lake looks different at different times of the year, {#blank#}10{#/blank#} (连词) it is always a good place to have fun!

    Have you ever heard of friendships among animals? At a zoo in Germany, an unusual friendship developed {#blank#}1{#/blank#} a cat and a bear.

    No one is quite sure how the friendship first began. One day, some {#blank#}2{#/blank#} (worker) in the zoo noticed a black cat was in the bears cage(笼子), and the two animals were playing together peacefully. They were surprised {#blank#}3{#/blank#} well the small cat seemed to get along with the large bear. The bear keeper allowed the cat to stay with the bear, And later the pair and their unusual friendship {#blank#}4{#/blank#} (become)a hot topic at the zoo.

    After several years, a new cage {#blank#}5{#/blank#} (build) for the bear. However, the cat was still in the same cage, so it walked around {#blank#}6{#/blank#} (angry) and cried to be with the bear. The bear keeper finally took pity on the cat {#blank#}7{#/blank#} let it stay with the bear. The cat and the bear got {#blank#}8{#/blank#} (close) than before. They often sat together and shared meals in {#blank#}9{#/blank#} sun.

    Sometimes it may be natural for animals {#blank#}10{#/blank#} (have) their own ideas about who would make a good friend. These may surprise humans, who usually expect animals to form relationships with others of the same species.

    We all know that a good night's rest helps us stay healthy. After we sleep for 7 or 8 hours in bed and {#blank#}1{#/blank#} up next morning, our mind is better prepared to memorize and learn something.

    But what about getting a rest during the middle of the day?

    Scientists say, “Short periods of sleep, napping (小睡), may help learning and memory. Napping can help young children learn better. It can {#blank#}2{#/blank#}  help older people remember longer.”

    Take China as an example. Chinese people are used to napping after lunch.

    Recently researchers made a survey among nearly 3,000 Chinese people over 65 years old. The researchers asked them {#blank#}3{#/blank#} they napped and for how long. They found that about 60 percent of them took a nap and they napped for 60 to 90 minutes. The research shows that napping for about an hour is the best.

    However, these are the findings for those  {#blank#}4{#/blank#} the age of 65. Doctors say that napping for about an hour may be too  {#blank#}5{#/blank#} for young and healthy people. And they believe that half an hour is enough to {#blank#}6{#/blank#} young and healthy people from feeling tired. By doing so, {#blank#}7{#/blank#} will help them stay awake.

    Doctors also say, “If you have trouble falling asleep at {#blank#}8{#/blank#} , take a daytime nap for less than 45 minutes and don't nap after 3 p.m. in the afternoon.
