______ has finished the work ahead of time will be rewarded though we don’t know______ it will be.

A. Who; who B. Whoever; whoever

C. Who; whoever D. Whoever; who

D

【解析】

试题解析:考察从句引导词。第一空考察主语从句引导词,who与whoever在语法上都符合,但是句意为在规定时间之前完成工作的任何人都会被奖励,故填whoever;第二空,考察宾语从句引导词,我们不知道这个人会是谁,没有表示任何人的意思,故填who。句意:任何在规定时间之前完成工作的人都会被奖励,尽管我们不知道它会是谁。故选D。

考点:考察从句引导词。

Be Your Own Best Friend

Why would you want to become your own best friend? There are a number of benefits of creating your own support system from within rather than relying on your partner, friends or family to be there for you when you’re suffering. We all have it in us to give ourselves what we need, without seeking it from outside. 1. Here’s how to become your own best friend.

1.Be nice to yourself

The first step in becoming a friend to yourself is to treat yourself like you would treat a friend. 2. Start by accepting your good qualities, talents and abilities and begin to appreciate yourself.

2. Imagine how you would support a friend in the same situation

Think about a loved one, a friend, a family member, or someone dear to you and imagine that they are in the same situation you are facing. 3. Then consider how to best offer help and advice to them. Allow yourself to feel supported, and give yourself what you need.

Write down the words that you would say to your greatest friend and then say them gently to yourself.

3. 4.

Following the theme of considering how you would help a dear friend, you need to start taking your own advice and putting your own needs first. Do you need a day off from work? 5. Whatever it is that you need, allow yourself to put it at the top of the list rather than the bottom.

Use these methods to become your own best friend and start being there for yourself!

A. Honor your needs

B. Believe in yourself.

C. A long hot bath?

D. Help them first and then they will help you.

E. That means that you need to stop being doubtful of yourself.

F. Think about how they’re struggling, suffering with this problem.

G. Isn’t it far better to know how to support yourself in times of need?

Harvard researchers have created a tough, low-cost, biodegradable(可生物降解的) material inspired by insects’ hard outer shells. The material’s inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative(替代物) to plastic. The material, made from shrimp(虾)shells and proteins produced from silk, is called “shrilk”. It is thin, clear, flexible and strong.

A major benefit of the material is its biodegradability. Plastic’s toughness and flexibility represented a revolution in materials science during the 1950s and 1960s. Decades later, however, plastic’s very durability(耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill(垃圾池) where they will degrade for centuries. What is the point of making something that lasts 1,000 years?

Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, fond in everything ranging from shrimp shells, insect bodies to living plants that makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material.

Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they’re exploring ways to use it in wet environments. They’re also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They’re even exploring combining it with other materials like carbon fibers, to give it new properties.

1. Paragraph 1 of the passage is mainly about shrilk’s ______________.

A. remarkable design

B. interesting name

C. major features

D. basic elements

2.What has become a concern about plastic?

A. Using it properly

B. Producing it cheaply

C. Developing its properties quickly

D. Evaluating its contributions fairly

3.According to the inventors, shrilk has great potential partly because _________ .

A. it can help plastic degrade

B. it can be found in living things

C. its mass production has been realized

D. its raw materials are plentiful in nature

4. What are the inventors doing in the lab?

A. Replacing carbon fibers with shrilk

B. Testing shrilk’s use in wet conditions

C. Making shrilk out of used household goods.

D. Improving shrilk’s flexibility for medical purposes

5. Which of the following can be the best title for the passage?

A. Recent Progress in Environment Protection

B. Benefits of Insects in Scientific Research

C. The Harm of One-time Products

D. A possible Alternative Plastic
