Golden Gate Park is in San Francisco, California. It is one of the largest urban {#blank#}1{#/blank#}(park) in the United States. Over one million colorful flowers, trees and other plants grow in the park. But originally most of the park{#blank#}2{#/blank#}(cover) in sand. After a lot of work, it was finally built in 1870. Today, there are many people{#blank#}3{#/blank#}(visit) the park every day. They play basketball, soccer, golf and many other sports there. The park is closed in many places to traffic so people can walk, cycle, or skate{#blank#}4{#/blank#}(free).

    China is leading the world in facial recognition algorithms（人脸识别算法）. It is reported that its best algorithm can recognize l0 million people {#blank#}1{#/blank#} a single mistake in less than a second.

    The top five of the 39 facial recognition algorithms in the word come from China, according to a test, {#blank#}2{#/blank#} released the results for 2018 last Friday. YITU Technology, {#blank#}3{#/blank#} Shanghai-based company that claimed both the top and second spot on the list, said that its top algorithm is able {#blank#}4{#/blank#} （recognize）nearly every person in a sample base of 10 million. However, "it is very likely for a human brain to make {#blank#}5{#/blank#} （mistake） in recognizing the identities of 100 people," the company said. Algorithms from Beijing-based company Sense Time {#blank#}6{#/blank#} （win） the third and fourth spot, while the Shenzhen Institutes of Advanced Technology（SIAT）claimed {#blank#}7{#/blank#} （five） in the test. YITU said that high facial recognition accuracy（精确）means that users gain {#blank#}8{#/blank#} （good） experiences when {#blank#}9{#/blank#} （use） related products. For example, when a user uses facial ID for payment on a smartphone, it will not authorize the payment for someone else with a similar {#blank#}10{#/blank#} （appear）as the user, the company noted.

    Do you have sleeping problems? If so, then these tips may help you fall asleep fast.

    Set aside the thought that you have to fall asleep. The more you think of it, the {#blank#}1{#/blank#} (hard) you will fall asleep.

    The foods you eat also play {#blank#}2{#/blank#} important part. Avoid eating or drinking things like chocolates, coffee, tea and energy drinks. If you have to, then have them in the morning and never in the afternoon, {#blank#}3{#/blank#} (especial) before going to bed. Don't eat too much at night. A full stomach will make it more difficult for you {#blank#}4{#/blank#} (fall) asleep because your body is working more time to digest the food you ate.

    Make a fixed time to go to bed. For example, by 9 o'clock in the evening you should already be {#blank#}5{#/blank#} bed. Do this even if you're not sleepy yet. Once {#blank#}6{#/blank#} (follow) this routine, you will gradually see that you will feel sleepy when it's 9 o'clock in the evening.

    Make your room {#blank#}7{#/blank#} (comfort) for sleeping. You should also take notes that the sleeping environment also {#blank#}8{#/blank#} (affect) your sleep. It must be in the room {#blank#}9{#/blank#} it's not noisy. Otherwise, you will find {#blank#}10{#/blank#} difficult to fall asleep again after waking up.

    Li Hua and Wang Hai are two students of Senior One. {#blank#}1{#/blank#}of them work hard but they have various learning methods.

    Li Hua listens to her teachers{#blank#}2{#/blank#}(attentive) and asks her teacher {#blank#}3{#/blank#}help as soon as possible if she has some problems. Because of this, she spends less time {#blank#}4{#/blank#}(do) her homework, so it is certain {#blank#}5{#/blank#} she can keep energetic in the day. However, Wang Hai has quite a{#blank#}6{#/blank#} (difference) way of learning{#blank#}7{#/blank#} (compare) to Li Hua. He likes to sit up late at night doing his homework, so he often feels sleepy in class. As a result, he misses lots of key points, {#blank#}8{#/blank#}makes it difficult for him{#blank#}9{#/blank#} (concentrate) on what he is doing.

    In my opinion, Li Hua learns more effectively in class and she{#blank#}10{#/blank#} be a better learner. So I prefer her learning method.
