文章大意:本文是一篇说明文。主要介绍了世界各地不同的文化中有不同的打招呼的方式,目的是为了让人们感到自己受欢迎,有些人只喜欢口头打招呼而不喜欢被接触,而有一些敏感植物也是一样,为了不被动物吃掉,受到触碰时会变成枯萎的样子。

【推荐1】Cultures across the world have different ways for people to greet one another. In New Zealand, they bump noses! The goal of these actions is to make others feel welcome. However, some people would rather say hello orally. They don’t like being touched. Neither does the sensitive plant. Some people keep the sensitive plant as a houseplant because of its interesting behavior. When you touch the leaves of the sensitive plant, it releases (释放) water from its leaves and stalks. As water runs to the plant’s base, the leaves close and the stalks droop. This causes the plant to look wilted (枯萎)!

The sensitive plant draws back from physical contact because it doesn’t want you to touch it, of course! Just like people, this plant sends physical signals that you should leave it alone. This reaction to touch is a defense system. Many animals and insects eat plants, so the sensitive plant learned to move to scare away predators (捕食者). Frightened by the sudden wilting, hungry animals move away to find a different plant to cat. Additionally, wilted plants don’t look mouth-watering. This encourages other nearby predators to look for their dinner elsewhere.

If you touch the sensitive plant and it wilts, have no fear! It’s still a healthy plant. After a few minutes, it will send water back to its leaves and stand straight up again. However, it takes lots of time for the sensitive plant to refresh itself. Don’t touch the plant just to watch it wilt. It may seem like fun, but it’s not fun for its refreshment.

It’s always important to pay attention to the body language of plants, animals, and other people! We should never want to make other living things uncomfortable, and especially not for our own entertainment.

1. What’s the main purpose of writing paragraph 1?
A.To introduce the cultures across the world.
B.To list the actions that can make others feel welcome.
C.To compare different ways for people to greet one another.
D.To lead readers to make a connection between people and the plant.
2. We can infer that the sensitive plant may be also called _________.
A.forget-me-notB.touch-me-notC.rose of sharonD.daughter of wind
3. The sensitive plant’s interesting behavior is actually a way to _________.
A.protect itselfB.entertain itselfC.attract animalsD.kill animals
4. In the writer’s view, _________.
A.watching the sensitive plant wilt is fun
B.we should treat other living things kindly
C.body language doesn’t help us know each other better
D.it’s a good idea to keep the sensitive plant as a houseplant

文章大意:本文介绍了不同的动物的尾巴的作用。

【推荐2】Many animals have tails(尾巴). They use their tails to do many different things.

Some animals use their tails as flyswatters(苍蝇拍). Have you ever seen a cow shake its tail back and forth? It’s driving away the flies. Horses also use their tails in the same way.

Some animals hang by their tails. Monkeys often do this. Then they can use all four of their paws for other things, such as eating. Monkeys use their tails as a “hanger”, which can help them hang in the trees and climb trees. Animals that live in the water use their tails to help them swim. A fish uses its tail from side to side. A kangaroo has a large, useful tail. It’s like a chair. The kangaroo stands on its tail to rest. It helps the kangaroo stand well. The tail is also good for landing. This is important because an adult kangaroo can jump as far as 15 feet at a time. A fox has a big tail. This is a good tail to have on cold nights. The fox can put its tail over its nose and paws while it sleeps. The tail can keep the fox warm.

Some animals don’t keep their tails with them at all times. If their enemies(敌人)catch them, their tails will break off(折断). Don’t worry. They will soon grow a new tail. How amazing(令人惊异的)it is!

文章大意:本文介绍了如何管理时间的一些方法建议。
【推荐3】下面文章中有5处需要添加小标题,请从以下选项(A、B、C、D、E和F)中选出符合各段意思的小标题。其中一项为多余选项。

How to manage your time

Time is very valuable. How to finish your plans in a limited time is very important to your work. The following tips may help you a lot.

    1    

Sometimes it is difficult to complete every task. The best way to achieve success is to make a plan. This starts as a list of all the tasks that are important to accomplish your goals.

    2    

Take a long, hard look at your relationship with e-mail and social media. Although they are important to everyday communication, they can draw your more attention than they deserve. Consider shutting them off completely as you work on a task that requires your full attention.

    3    

Those asking you to take part in their activities would be more disappointed if you unwisely agreed to do something, but then failed to do it. Learn to refuse them and be honest with others.

    4    

Taking breaks is good for your brain. Don’t be hard on yourself: you will actually perform better if you take breaks. This might seem to be opposite to all those tasks on your list, but ways to deal with difficult problems can come from a refreshed brain.   

    5    

Your plan and priority list will need to be regularly updated, particularly when things are not going well. Don’t be nervous if your plans fail: instead, rewrite your plan and aim to get rid of all other unnecessary tasks.

A.Update(更新) your plan
B.Learn to say “no”
C.Make a plan
D.Don’t pay attention to something unimportant
E.Do one thing at a time
F.Give yourself a break
