In order to know a foreign language thoroughly, four things are necessary. Firstly, we must understand the language when we hear {#blank#}1{#/blank#} spoken. Secondly, we must be able to speak it correctly with confidence and without hesitation. {#blank#}2{#/blank#}, we must be able to read the language,and fourthly, we must be able to write it. We must be able to make sentences that are grammatically correct.

    There is no easy way to success {#blank#}3{#/blank#} language learning. {#blank#}4{#/blank#} good memory is of great help, but it is not enough only {#blank#}5{#/blank#} (memorize) rules from a grammar book. It is not much use learning by heart long list of words and {#blank#}6{#/blank#}  meaning, studying the dictionary and so on. We must learn by using the language. {#blank#}7{#/blank#} we are satisfied with only a few rules we have memorized, we are not really learning the language. "Learn through use" is a good piece of {#blank#}8{#/blank#}  (advise) for those {#blank#}9{#/blank#} are studying a new language. Practice is important. We must practice speaking and {#blank#}10{#/blank#} (write) the language whenever we can.

    Once I was playing in the woods when the sky started to turn dark and the wind started to blow. I saw a big black cloud{#blank#}1{#/blank#}(move) towards me. Suddenly, I felt the rain hitting my face! Actually, it was pouring! Then I saw lightning in the sky. And later, BOOM!!! A loud clap of thunder! Then I saw a little old hut and ran inside. It smelled awful and the walls were shaking, but it was{#blank#}2{#/blank#}(good) than nothing! Outside, the wind was howling and things were flying around. I just stood in the corner, cold and scared.{#blank#}3{#/blank#}(lucky) my dad came and found me. I was safe!

    Electric bicycles have made life a lot {#blank#}1{#/blank#}(easy) for food delivery workers here in China. More than 10,000 kilometers away, there was a familiar sight in New York City. {#blank#}2{#/blank#}, owing to a new policy, e-bikes can no longer be{#blank#}3{#/blank#}(common) seen on the street over there.

    City officials in New York are promising a crackdown(严厉打击) on e-bikes  The pollution-free vehicles are loved by environmentalists and the often poor workforce {#blank#}4{#/blank#}. relies on them. But there are also frequent complaints{#blank#}5{#/blank#} the bicycles from drivers and pedestrians(行人) who consider them{#blank#}6{#/blank#} public danger.

    Now it is legal to own and sell the bicycles, but{#blank#}7{#/blank#}(ride) them on the street could lead to a fine of up to $500. Businesses that equip their{#blank#}8{#/blank#}(employ) with the bicycles will also be heavily fined.

    The bicycles, which look just like regular bicycles, can reach speeds of 30 km/h and are sometimes operated recklessly (鲁莽的). Lots of people have stories about dangerous situations where they{#blank#}9{#/blank#}(step) out into the street, only to be nearly hit by a quick-moving e-bike.

    Police enforcement (强制执行) against the bicycles has already been tightened. Almost 1,000 of them{#blank#}10{#/blank#} (take) away by police since last year, an increase of several hundred from the year before.

    I paid a visit {#blank#}1{#/blank#} Cambridge last January. Though the trip took me 5 hours and it rained the whole day with strong winds, the town deserved a visit.

    The bus started at 6:10 am. It stopped at 4 stops before we finally arrived, {#blank#}2{#/blank#} wasted more time than we had expected. {#blank#}3{#/blank#}(tire) with long time of sitting, one passenger stood up to relax his numb (麻木的) legs. The driver asked him to sit down but in vain. So he pulled up and said {#blank#}4{#/blank#} (serious), "You either get off or sit down." To him, {#blank#}5{#/blank#} (safe) was the first policy.

    Cambridge consists of nearly thirty colleges. The {#blank#}6{#/blank#} (old) part of the university was built in the 13th century {#blank#}7{#/blank#} the newest was founded in the mid-1960s. The number of the students {#blank#}8{#/blank#}(be) so great that many students live in lodgings（出租房）and move into college for their final year.

    The heart of Cambridge has shops, pubs, and supermarkets, but most of it is university colleges, departments, libraries and other places for university staff and students. Students fill the shops, cafes, banks and churches, {#blank#}9{#/blank#} (make) them as well part of the university.

    With over 10,000 undergraduates and postgraduates, the town is a busy place indeed. Students here are not allowed {#blank#}10{#/blank#} (keep) cars. If you happen to be walking in the street during a break, you'd better stop for a moment to avoid the sea of bicycles hurrying in all directions, which carry students from one college or a lecture room to another.
