The earth’s surface temperature     3    (go) up by about 1 degrees centigrade in the past 100 years. As a matter of fact, we may feel that we can hardly put up with the extremely hot summer and we can’t get accustomed to warm winter. The rise of the earth’s surface temperature has made much     4    (different) to human health, the existence of creatures     5     the balance of ecosystems. There is no doubt that it is human activities that result     6     the bad environment. As a     7    (consequent), conditions permitting, all countries in the world should try their best     8    (improve) our environment. Even if our effect is limited, it will     9    (eventual) make a great difference if we keep on     10    (work) together to deal with global warming. Without all people’s joint efforts, what would our future be like?

There are many types of reports. A report is simply an account of something that    1       (happen). The commonest    2       (be) news reports. We get them in newspapers, over radio and on television. Sometimes cinemas also show us newsreels.

The main purpose of a newspaper is to provide news.       3    you examine a newspaper closely, you will find that there are all types of news: accidents, floods, wars, fashions, sports, books, etc. The news covers everything     4     happens to people and their surroundings. Sometimes there are news items which are very    5     (amuse).

A news report is usually very short,     6       when it is about something very important and it contains a lot of information. It is also written in short paragraphs. The first paragraph is in fact a summary of the news item. It gives all the necessary information, what, when, where, how and why. The     7       paragraphs give full details of the subjects. There may also be interviews     8       people. The words actually    9       (speak) by them are within inverted commas.

Often there are photographs to go with the news    10     (make) it more interesting.

【推荐2】Generally speaking, joy     1    (express) by laughter. But as it turns out, it reveals a lot more than the fact     2     you are happy. It enables listeners, even those who cannot observe you,     3    (realize) if you are having a good time with a close friend or laughing     4    (polite) with a complete stranger.

At least, this is the conclusion     5    (reach) by a team of scientists led by Greg Bryant,    6     assistant professor of Communication Studies at the University of California, Los Angeles. The researchers began by     7    (request) volunteers from across the world to send them audio clips(音频剪辑) of people laughing. The 48 tapes they received     8    (range) from recent recordings of laughter between two college friends     9     ones from conversations made ten years ago. The clips also had all possible     10    (combine)---communications between friends, strangers, all-male groups, all-female groups, etc.

Bryan says that the results of this cross-cultural examination show that people all over the world know laughter in similar ways.

As humans, we have five tools     1     help us explore the world around us. The first one is sight. You can watch a movie, see a beautiful sunset, or run and play outside because of your     2     (eye). The second important sense is hearing. Our ears allow us     3       (enjoy) things like talking with our friends and listening to music.     4     (be) able to hear also helps protect us from     5     (dangerous); for example, we can hear if a car is coming when we’re crossing the street. Smell is another important sense.     6       our noses we couldn’t enjoy things like our favourite meal or flowers. Our nose also helps us know     7     we’re eating. The     8     (four) important sense is taste. Our tongues (舌头) can pick out five types of tastes — bitter, sour, sweet, hot and     9       (salt). The last important sense is touch. Our skin is very sensitive (敏感的) to what it touches, allowing us to feel. Our sense of touch can also prevent us     10     (hurt).
